Also change the expansion tank cap, its probably not holding the pressure.

sounds to me like a possible air-lock. might be worth seeing if it is,before buying a new thermostat & cap.

go with Bruce on this one, the cap is the cheapest fix, and one I should have remembered, a new cap is a few quid, a thermo and housing isnt!

Post it to the appropriate forum :P

 

so if its a mondeo question, post it in the mondeo section, if its a general question not specifically to the mondeo, the general Ford, or if its naff all to do with cars, the general chat :P
