O2 Sensor problem?

Posted on 21 May, 2020 at 18:00 Comments comments (20)

O2 sensors measure the burn rate of the exhaust gasses. This information is sent to the computer to calculate the intake of fuel and air for the next combustion stroke. If you have scanned your car and found an O2 sensor code, it doesn't mean the O2 sensor is always faulty. If you use the term 'We are what we eat' then this also applies to your car. If you have bad fuel or cheap 91 fuel in your tank then the combustion burn will no be as high as good 98 fuel. If you look at fuel rates, 91 means only 91% of the fuel will be burnt, another 4 to 5% of the fuel will recirculate and burn up eventually but the remainer 3% will deposit as sludge and gradually build up in your intake and throttle body. If the O2 sensor comes up as faulty, remove the sensor and check for unburnt carbon deposits. cleaning the O2 can save you heaps

Proper Air Conditioning use

Posted on 2 March, 2020 at 16:20 Comments comments (21)

In Cairns, inside vehicle temperature can reach 120 cel, most people jump into the hot car, turn on the A/C and drive away without giving it another thought.

Every vehicle is fitted with a recircualtion/vent switch. There is a reason for this. When you get into the hot vehicle you should wind the windows down, put the vent on fresh and run until the majority of hot air inside the vehicle is despirsed. you will feel it when it's cooler, then wind the windows up and put on recirc.

By turning on the AC and recirculating hot air this puts more stress onto the engine as the AC compressor takes longer cycles to cool the cabin of the vehicle. This means more stress on the AC system, more stress on the engine and more fuel used to cool the car. The fuel used to cool when on recirc is excessive, it may cost you only 30 cents extra but think of that cost when you stop and start over a 6 month period. Makes sense to operate the AC the proper way than to pour your money down the drain.

Warm Up

Posted on 2 March, 2020 at 16:05 Comments comments (0)

When you turn off your car and park it for the day or night, all the oil in the engine drains back into the sump, the coolant cools and the thermostat closes.

In the morning when you start it up and drive it straight away, without giving it enought time to warm up you are actually causing premature wear and tear on your engine.

You may say that warming your engine is an old fashioned way of doing things, but warming up is actually written in most manuals you get when you buy your car. Loading up is a term that means you stress the engine or put load onto the engine, if you load it up when cold, or drop it into drive and drive it straight away the lubrication hasn't had sufficient time to get through all the oil galleries, the engine revs slightly higher as its cold and more fuel is deposited until warm up is completed.

All you need to do is start you car and wait until the temp guage gets to normal operating temp, then drive it. This way you don't stress out the engine, you will get better fuel economy and performance and reduce wear and tear on your engine. This applies to any engine from a ferarri to a lawn mower, regardless what engine oil you use, even aircraft need to warm up before flying, it makes sense to warm your engine up before you use it.

Nissan Patrol 2009 3.0ltr belt tensioners

Posted on 17 January, 2020 at 21:20 Comments comments (25)

When going to change a drive belt on these models they are a nightmare, Usually the little shock absorber tensioner fails and you will need to change the whole tensioner. People go for the cheaper part so the cheapest part is a Gates 39214 Drive belt tesioner, however when you buy this cheap part you need to add the drive belt that they say suits the pulley @ $90.00 as the pulley is larger than the original. Next problem is the design of this engine as all the pulleys the drive belt runs on have what we call belt keepers. Belt keepers are a higher ridge pulley designed to keep the belt true to the belt grooves, but if you use the belt recommended ( 7PK1640) you will find this belt runs short, so you cannot get the belt over the keepers, all pulleys in nissans have keepers unlike everything else that has one pulley that the keeper is left off in order so you can get the new belt onto the pulley, the nissan engineers must have had a day off when designing this set up. This engine was partly designed by English engineers, This explains why there is problems as they really must be mummys boys to get them into engineering school, they create more problems with their designs, not solutions. So if you insist on the cheaper Gates tensioner then the recommended belt 7PK1640 will not fit, you need a 7PK1643 that is not available and the 7PK1645 is too large, it will fit but the tension will be too poor. The remedy using the cheaper tensioner is to remove the original pulley, replace the bearing and install the old pully to the new gates tensioner. This way when the belt breaks or after it's worn you will be able to get the correct belt when you quote your rego number or the other option you have is to buy the more expensive pulley or genuine pulley. The extra time needed to try and make this cheap tensioner fit far outweighs the extra cost of buying the tensioner that does fit. I've contacted Gates about this and they don't want to know about it, blaming this individual Patrol to my problem. But this is what i have experienced on at least 5 other models, so it's not a particular vehicle that causes this problem. It's the chinese lack of quailty that is infecting the automotive industry! My advise is buy a genuine belt tensioner or fork out a few extra for the correct size pulley, unless you want to go crazy rolling around on the grass in someone's driveway with dog shit stuck to your hair, is it really worth the stress?

Supercheap Auto ok with me

Posted on 22 October, 2019 at 20:45 Comments comments (78)

Supercheap over the years have picked up there act, before around 10 years ago I wouldn't buy supercheap products as they were cheap and nasty but now they are stocking brands found in all the major suppliers like Repco etc, except they are much cheaper. Tool pro for example are decent tools compared with what they used to sell, brands like Penrite and Bendex brake pads are the usual stocks they stock now, mind you some of the products i still wouldn't buy like sockets etc as i use them everyday, but for people who use tools on a week-end basis you can't go past Supercheap Auto.

They have extensive ranges of fridges and camping supplies, most of which I own for example the 40ltr EvaCool fridge I purchased 1 1/2 years ago hasn't missed a beat. the staff at Manunda store are excellent to deal with and very helpful, even the battery range are Century and aways use these batteries for my customers. My aim is to provide the best quality repairs and services with budget in mind. If your shopping for parts, oils etc you really can't go past Supercheap Auto Manunda.

Beware the Mobile Mech in a blue kia Rio

Posted on 13 September, 2019 at 1:10 Comments comments (119)

If a 'Mechanic' pulls up in your driveway in a blue Kia Rio like above then consider this. Ask to see his public liablity insurance certificate, he has none. ask also to see his qualifications, he has only a brief history with Toyota as a technician, a technician is not a Mechanic, it's a termination that dealerships use to train someone to do small jobs like servicing etc, they add the term 'Factory trained Technician' when we have no factory training in Australia, only specific training undertaken by dealerships and visiting dealer brand trainers.
I say this because this so called trade qualified 'Mechanic' tried to come into business with me, but when I done a trade check, his name does not come up as trade qualified in any state. I also asked him to provide his own public liability insurance, and questioned to see some trade papers, he slid the key to the workshop under my door and vanished. later I found out he was on the dole and doing cash in hand work advertising as a mobile mechanic. I need to make the public aware that if he repairs or services your car on your property and if he damages your car or injures someone, you will most likely experience this vanishing act he seems so good at. 

keeping your cool

Posted on 21 July, 2019 at 2:20 Comments comments (16)

Thermostats act as a regulator to slow your cooling system flow down enough to allow coolant to cool sufficiently

Thermostats usually fail in either stuck close or stuck open. If you Follow YouTube Mechanic's

guide to keeping your engine running cool, then I suppose you deserve the outcome of that lesson.

Cutting the guts out of your thermostat is ok to get you out of a situation, but to teach it as a fix

Is both wrong and unprofessional. If the coolant cannot slow enough to cool down properly the

increase in pressure will cause serious problems, like radiator expansion and added pressure to

gaskets and seals, more heat = more friction, added stress to engine oil and coolant, increase

In poor fuel economy and performance, it will also stress out the battery as the thermo fans need

to work longer to keep the engine cool. So much for the YouTube Mechanic.

Car Yard Dealers

Posted on 27 May, 2019 at 4:00 Comments comments (10)

I've been around a few years, i know the ins and outs of the Automotive Industry. I'm speaking from personal encounters with Local Car yards. I've been insulted by an offer one Car yard has offered for a trade against one of their vehicles against my vehicle as a trade. Now my 4WD is immaculate, nothing wrong with it, in fact a new gearbox installed 3 weeks ago, but the trade in price was $1500. The new gearbox is worth $3600. I rest my case.

I only wanted to trade down to a 2WD as I have no need for a 4WD and this is my work vehicle, it's spot on, it has to be! But dealing with these Morons really got my back up. I took it as an insult, then I remembered that once I advised one of my customers against buying from this Car Yard as the vehicle had a list of faults, I cost them a sale! Hence the reason for the insulting trade in price.

Seems I won't get a good trade in as they didn't like me joining there sales pitch with my customer. For that I make no apoligies. If I inspect a vehicle for the purchase from one of my customers and if I find faults, it's my duty to report ALL findings to my customer and advise with or against for the purchase or No Sale. If it doesn't pass, it doesn't pass.

So lets expose some sales tactics to the general public and if your saleperson uses these tactics, I strongly advise against using this salesperson.

1. Warranties. Every consumer that purchases a Used vehicle HAS to acknowledge that by consumer law they are given a statutory 30 day warranty. They upsell you a dealership warranty that has more clauses and conditions to that of a property purchase that makes it impossible to claim. They waste mechanics time asking for reports and quotes only to find it's not covered. Mr or Mrs consumer goes back to the Car yard to have the vehicle fixed but they get the buck pass back onto the warranty they forked out 100's for.

In other words they insist on selling you this warranty so when the shit box they are selling you breaks down they have an avenue of which to escape, they pass the buck onto your warranty only to find there's a clause that they won't pay for it. Do NOT buy one of these Warranties. You DO have normal consumer rights and a 30 day cooling off period by Queensland LAW. (They will not tell you this, the warranty they give you is there scape goat and designed to make it confusing when you use the word 'Warranty').

2. Stay away from vehicles that have no price. If you look at a vehicle that has no price then you don't have any control over the power of the sale. When you pull up outside they already know what your trade in will be, ask up front how much the car is and park a few meters down the road, don't answer any questions untill he/she has given you the purchase price. When you ask the price he/she will answer with another question, usually 'Do you have a trade?' Then he will give you the price. If he/she does this, walk away. Go to a different Car Yard with a price on the screen.

3. Used Car salespersons are not your friend. A Coffee and a chat is called 'Breaking the ice'. They have to seem interested in your life, but at the back of their minds they can't wait till you drive off with one of there pearlers. After the sale they don't want to hear from you again. That sounds cold, but it's the truth. They have more best friends coming to buy more Cars they have no time for your friendship.

4. Upsell. It's not enough that they buy a Car for 1500 and sell it for 10000, no they have to get comissions on all those usless 'extras' they feel the need to sell you while they write up the deal. Window Tint, side steps, alloy bodies, upgraded sound systems, battery systems, scotchguard seats, vinyl protection, rust proofing, paint protection the there's that all important clause to keep your warranty you have to service with them. You may as well give them a blank cheque. You will save 1000's getting extras for your car if you source those extras after the sale. Most of these extras are available online for a fraction of the cost, even EBay! Just concentrate on getting the car, it's fun to add the extras after the sale and you get your car looking exactly the way you want it. Not to mention the huge savings!

5. If you leave a Car yard thinking you got a bargain, chances are it's the salesperson who has the bargain. Thinking you are fully covered is NOT the same as actually being covered. do your research, don't trust a salesperson.

Service Prices.......Confused?

Posted on 12 April, 2019 at 2:20 Comments comments (10)

I got some feedback with not stating my Service prices, there is a valid reason for this and much of the confusion is understanding what is exactly a Service.

A General Service is a Engine Oil and filter change check all safety related items, tyre inflation, grease tailshafts and electrical tests and a scan of the computer, I throw in a wash and tyre shine in most cases, weather permitting.

A Major Service is all Fluids, all filters, tune up, brake caliper lube, and the list is huge.

A log book Service is a Service that has to be done to keep a Warranty valid and has to be done as per the manufactors specifications and Instructions.

So when someone calls me to inquire about a price, it's important to know what kind of Service you need. Then I can Quote you.

Every kind of Service requires different kinds of Parts, Oils and Filters. It's vital that the grade of Oil recommended for your car is used, I use good quality Oils and filters and the correct weight of Oil.

Take the $100.00 special Service for example, lots of business around here do this 'Special Service' to fault find your car, get more work out of you and to be honest, some of the things they say that need to be done straight away can often wait and can be spread out to suit most peoples budgets, not with the cheapo service guy, he wants your money now! I've been in the Automotive trade for 37 years and am well aware of the tactics taken especially from dealerships to upsell you as much as possible, squeeze every cent they can out of you and basically lie there ass off to keep you coming back and paying, how do you think they keep those flash coffee machines and air con lounges going?.....YOU PAY FOR THAT.

I vowed never to do this with my business, people come to me for my Skills, not to be upsold and grab your last penny.

Back to the $100 Special Service. Think about it before you book your car in, the generic oil they use will go in your engine, the cheap chinese oil filter will be installed, then it's on to fill a page with problems so the so called Mechanic will get a good commission at the end of the month. There is no such thing as a generic oil suited for all cars, it HAS to be the correct spec of Oil for the engine you own, same with gear oils, coolants etc and the bulk Oil they use is low quality, I know of one business that uses recycled Oil. That's a big no no and besides this it's my policy not to do anything to someone else's car that I wouldn't do on my own car and my cars are immaculate.

So for me to give you a price, you need to be aware that I intend to give your car the best service possible and use the correct materials to give you better fuel economy and make you car last longer, same goes with any repair I do, I can provide a quote but the reason I do not advertise a Cheap Service is all cars are different and it's impossible to quote a generic price as I do not do generic servicing, I don't have bulk Oils and buy the correct parts and materials to suit your make and model. I can guarantee though that I will beat ANY dealership price on Servicing or Repairs with a 12/20 warranty, as I don't have that flash coffee machine or Air Con lounge, but my customers get a better job and more money in there pocket! That should be good enough reasons to choose Everything Mechanical.

I thought I would give my veiwers the run down on Thermostats, what they do, how they work and the importance of cooling system service. I often get vehicles with faulty Thermostats. Please see below pic of the cooling system to give you a broader view of what i'm trying to explain.

A Thermostat slows and speeds coolant flow in the form of a resistance valve (thermostat) to allow coolant to cool at a slower rate, keeping the vehicle at it's specified normal running temperature. Gone are the days when you can cut the center out of a thermostat to get you going. Overtemp especially with vehicles with alloy and plastic radiators are fragile and overtemp means overpressure, it can also blow gaskets and seals all over the cooling system.

To avoid your cooling system being damaged you can get it serviced and the thermostat replaced every 2 years, avoid putting water in your cooling system and only use a full concentrate 5ltr bottle, no water. Water is a corrosive it carves valleys in mountains and does the same to your cooling system, some of the chemicals in water such as chlorine and flouride have an effect on the chemicals in the coolant such as glycol, if you must top up with water, use a demineralized water. Use a top quality coolant such as Penrite. And pay the extra for a genuine Thermostat as most aftermarket thermostats open at a different temp.

Damage: A closed Thermostat can, and often causes headgasket failure, cylinder bore glaze and cracked cylinder heads, not to mention expanded cooling systems. If you have a faulty thermostat it won't always let you know by the temperature guage, depends on the design of the engine if they place the sensor before or after the thermostat, I wonder sometimes if these Mechanical Engineers actually use the brain required to become an engineer, some of the cooling systems on thes new cars are simply not made for Australian climate and road conditions, imports are imported with the full flow thermostats for colder climates, they run fast flow coolant and overtime (at the end of the warranty period) the cooling system starts to leak and breakdown due to years of overpressure, all because they are not bothered to install a slower flow thermostat for Australian conditions. Imports which are now all new cars are generically made and exported to the world, no cars are made for our conditions except Toyota. Holdens are no longer Australian, they are Euro, hang your head in shame Holden, you're filling the road with shitboxes.

So that's a pretty good run down of a Thermostat, don't let the backyarder cut the guts out of your thermostat and she'll be right mate, do the right thing and get your cooling system serviced by a qualified mechanic, a drain and re-fill is NOT a service!
