Chaps, a problem is occuring and I would like some guidance as to the possible roots of the this!
In essense..
I have replaced the thermostat, refilled the water system, bled the system.
On driving the car, temperature stays fairly normal, however when idling it has boiled and does rise to 90 degrees plus, to alleviate this i turn on the heater and run this on hot, this bring the temperature down again.
When the car boiled the other day, the fan did not kick in, however it does normally!
There is no emulsion on the oil filler cap, no obvious oil in the water, however, when I turn off the engine after a run, the water system appears to have been pressurised and the header tank weeps water. Letting the engine cool and removing the cap from the header tank the water system remains pressurised.
Thoughts??
cheesy geezer 😬
