harveyp6 said:If the engine is so hot that it's burning off long lying residual oil and grease then it is running too hot. When that happens they just smell "HOT" too. Regardless of what you've done so far, you need to go back to the beginning and start again. (I don't mean replacing all the new parts you fitted, but I do mean checking them all very carefully), Along with all the normal suspects like the bleed pipe and manifold, and all the head gasket symptoms.

Coolant loss, micro bubbles in the coolant, excess pressure in the cooling system, steam/condensation/antifreeze smell from the exhaust, but as always check all the other, easier, things first.
Possibly, it s something that I will check.stina said:Is it possible you have an air lock in the system somewhere ?

I'll try that Paul, but I don't suppose there is a way of telling if its pumping strongly enough?
rockdemon said:well mine drops about an inch from the top of the rad when i rev it - without an expansion tank yours should do similar i guess?

The thermostat should always ensure that it gets up to temperature, unless it's so cold that it doesn't get hot enough for the stat to open, and I can't see that happening. If the cooling system is that efficient then the stat will just close again.
Hi Ron,SydneyRoverP6B said:Hi Mike,
Are you able to rule out that the thermostat is actually opening at the specified temperature?
Twice I have had a thermostat that when it failed actually closed rather than remaining open, and the coolant temperature rose rapidly as a result approaching the red before I shut it down.
I would be inclined to replace it straight away as a matter of course, then keep an eye out for symptoms of head gasket failure which may have occured from the engine overheating.
Ron.
