The tick creamy sludge is caused by oil and coolant mixing - so you need to know the original cause of that mixing - i.e. how is the oil getting into the coolant in the first place. The most common causes of this are failures of headgaskets or oil coolers. The suggestion that it will take some time for all the oil to be flushed out is rubbish, as any ...

Yes, overheating the engine can damage head gaskets and warp or crack the head(s) (4 cylinders have one head). On these types of engines, the heads mounts to the top of the engine and are (typically) made of aluminum. The engine, on the other hand, is made of cast iron and is very thick and heavy. So, when the engine gets too hot it can withstand the ...

If the gauge went all the way to the "H" you have no idea how hot the motor actually got because the gauge was at it maximum. If you had a leak the cooling system was low on coolant. the more coolant lost the hotter the engine ran. There is a good chance some damage was done from the motor overheating. There are tests your mechanic can do to confirm a bad ...

A big fat NO. I'm a corrosion engineer, trust me you don't have to play with the PH of solution and alter (generally increase) the corrosion rate of your radiator. Corrosion rates can raise up to like your radiator vanishing in 6-8 months. PH highly influences corrosion of copper that's why the coolant has a inhibitor (chemical specie) that controls the PH ...

There is nothing inherently wrong with what the service manager told you. (As an aside, service managers and mechanics are looking for add-on work. They get paid more money for this work than work you bring to them to do. If he says it's not a problem, believe them, because if they could make some money off of you, they'll do it.) If it serves your peace of ...
