how do you change the thermostat on on a 1.8 zetec escort si,
does cambelt need removing,
is it hard,
thanks

 

It's the other end of the engine to the belt, quite easy job, just undo pipes and bolts on stat housing to get at it, make sure to get a new o ring seal, should be with kit, and don't overdo the bolts upon reassembly as housing plastic can break.

When I did mine on my st170 there was no need to remove any pipes. Undo 3 torx screws, whip out old stat, slot new one in, job jobbed. Just make sure you fit the seal on the stat before it goes in, and put a bowl or something underneath the stat housing to collect lost coolant (you will get about half a litre), stick the coolant back in the header tank, 10 minute job!
