Hi,

I own a 2002 Ford Mondeo 2.0 Ghia.
I try to do all the fixing by my self.
I have this problem that I am unable to fix for a while now.
The car heats up when I STOP. I have to push on the gaz in order for it to cool down abit and that does not always work.

Here's the thing! I have replaced the:
1) Radiator
2) Thermostat
3) Water pump
4) all tubes plus coolant reservoir tank

No water is missing. No oil is missing.

the car still heats up.
I am frustrated.

please help.

 

have you changed the actual temperature sender-or checked the actual temperature of the coolant...? it may not be overheating at all

 

The temperature gauge is smack in the middle as it should be but only for the 1st 20mins so I assume if it shows the normal temperature at 1st it shows the overheating correctly as well.

 

not always-as the sender gets up to temperature it can misbehave-worth trying a new one for little expenditure-and or wire up a capilliary gauge to measure the actual temperature of coolant-or use a heat/temperature sensing gun
worth also checking if the cooling fan is turning the correct way-thats assuming it works as it should-if engine is genuinely hot it should be on trying to cool it

 

I have checked the temperture. the engine is most definitely overheating.

however, I have noticed something which I think is weird.
There are little tiny bubbles climbing back into the reservoir tank. (kinda like soda)
could it be a compression lose?! causing the pistons to rise the temperature of the water?

 

if its bubbling up it could be headgasket/cracked head/block etc

check for hydrocarbons in expansion bottle and go from there
