Guys,

2WD Cosworth engine, bailey header tank... temp gauge sits at quater, only rises if giving it the beans down a motorway and has never gone over halfway.

Fans have kicked in once since I have owned the car

Never burns any oil or water

No sludge in the oil

No smell in the header tank

All pipes get hot

Water boiled over when the temp gauge was between quater and halfway on the temp gauge... fans did not kick in at all...

No funny running problems, runs fine, pulls fine, no funny noises or extream condensation coming from the exhaust etc...

Any ideas?

Been told to check for air leaks, take the stat out and check it opens, common for these to stick which is a common or the water pump...


Now I guess the water pump is fine as all the pipes are hot? all the same kind of temp...?

Also I am guessing now air locks as all the pipes are hot?

Can anyone give me some instruction on removing the stat please... where, what to do, etc etc.

I want to take it out and put it in boiling water to see if it opens or not... pretty sure this is where my problem lies...


Also to add, the heater in the car works fine

Thanks in advance

Mark
