2002 escape 2.0L Zetec 4-cyl 5MTThere was a significant leak at the thermostat real estate where that mates w the engine. As explained in plenty of topics across the internet, the housing plastic crumbled in one spot at the groove because that the real estate gasket, causing the leak. I installed an alternative thermostat housing for a 1998 Ford edge (the 2000 Contour housing could likewise be used). Part say a leaking valve sheathe gasket is responsible for the leak, as hot oil it s okay on the therm real estate & hsng gasket. Ns think the trouble is the real estate itself, due to the fact that it is plastic which i do not care brittle. Mine valve cover had been leaking, so ns went ahead & changed that gasket first, which was easy other than for the darn wiring exploit clips that space fitted on two of the valve sheathe bolt studs. One of the therm real estate bolts additionally has a stud w a clip.Ford focus housing (internet photo) -->> the escape is similar. It"s difficult to view in the photo, however the plastic is broken where the gasket is split... Mine to be similar.
