hi all , iv a problem with a mini which I can’t seem to figure out I’ll give some details of the car
Mini one
2011
1.6
Ok there’s pressure building in the coolant system and bubbling so my first guess was the head gasket so tested for exhaust gas to my surprise there was none picked up (using that color changing liquid) so my next guess was the thermostat stuck closed and overheating making the coolant bubble, so changed that didn’t fix it so this is were it gets tricky only happens when engine is revs on Tick over its fine , now If you rev the engine and watch the coolant rise in the expansion as soon as you put the fan on hot or cold the coolant will return the original level and no more gas bubbles or pressure so can’t figure out what the fan has to do with pressure in the system please help |
