What's this? you may ask, I'm committed to customer service and buy all the necessary tools to do the job right the first time, if you call a mobile mechanic and he shows up with a toolbox, get another mechanic, mobile mechanic's in my view need to have the right tool for the job. This little tool is a cylinder head diagnosis tool, the way it works is you add this dye and pump it in your cooling system, if the dye changes color to a yellow, this means you have emissions in the cooling system and diagnoses would be a blown head gasket, it's very accurate, expensive but my customers deserve the best.

That's good oil - Great Service! call John 0498 483 681 or www.everythingmechanical.com.au
