cooling issue
come off motorway and temp rises quite quickly to just below half way
hit traffic and temp rises quickly to 3/4 when fan comes in and takes it down to just below half way
Any ideas - thermostat ??? cap on header tank ??? water pump ??

When I bought my car it had this problem. Thermostat solved it but caused a few others!
Bad timing was causing the car to overheat. Which had been balanced by the dodgy thermostat.
Also heard of people removing them to hide overheating problems.
You will lose all the coolant changing the thermostat so remember to have some proper coolant ready to put back in, not crappy tapwater which is full of mud and chalk.
You will need a new rubber o ring aswell or it will leak forever.
When I did mine I half emptied coolant then poured in some traffic film remover and ran the engine till hot to give the cooling system a good clean. Anyone tried it? Someone reccomended it as I kept getting crap in my filler cap. It worked.
Probably not worth doing unless your coolant is manky like mine was. If you do try it remember to put the heater to hot to give the heater matrix a good clean aswell.

so far all seems well - car heats up a lot quicker with the needle sitting just a tad below half way no matter what happens. Hopefully all is cured now
