Infamous T-stat housing seal.

So the lady and I were driving around today, and in the midst of stop-and-go traffic, I noticed the temp. gauge creeping toward the warm end. Lo and behold, the thermostat housing is leaking. Is there anything I should watch for while tackling this, or is it really as easy as it looks? Thanks!

I moved your thread to the Technical Chat area, the Zetec Performance area is for zetec performance parts.


It's as easy as it looks

Take the battery and the battery tray out and loosen the ignition coil and move it out of the way this gives you plenty of room to get to everything you need to get to ie the radiator drain plug, hose clamps and bolts.

Just take note not to make it to tight, my uncle tightened his to much and it wound up cracking again about 200 miles latter... He's actually a diesel mechanic so, more than likely he wasn't considering more fragile components. So long as you keep that in mind though you'll be just fine!

Just did mine about a month or so ago. Probably one of the easiest things I've done. Only thing easier was the DPFE sensor lol

I dunno, I think disconnecting the battery is probably the easiest thing to do lol though the DPFE is a close second lol

I just replaced mine this afternoon, so it's still fresh in my mind (and under my fingernails).

Like a previous poster mentioned, remove the battery & cradle for better access; when I do that, I often will also remove the air box, intake runner, and fresh-air duct to provide maximum elbow room. I removed the ignition coil pigtails, but left the coil alone.

Here's a common sense tip, but I'll mention it anyway 'cause there have been several threads with complaints about new thermostat housings leaking after a few weeks/months: attach the three largest hoses to the new thermostat housing before you attach it to the cylinder head. That way, you won't be leveraging the housing (and its rubber seal) when shoving the hoses onto it.

Also, I think that's an asbestos blanket on the EGR pipe, so wrap something like newspaper or saran wrap around it after you remove the battery, because you'll be working around it the whole time. Asbestos is nothing to f___ around with.

Finally, after removing the old thermostat housing, take a few minutes to look around for anything that's convenient to replace now. It's not often that the entire drivers-side of the engine compartment is opened-up, so it's a good time to check/replace the PCV valve, check the PCV hose for cracks, check all radiator hoses, replace driver's side motor mount, etc etc.

X2. I always pull coil and bracket for room. I always do it to slot out the bottom forward bracket hole with a dremel so it is easier to remove bracket later, you don't have to completely remove that bolt after that, only loosen it a bit and leave it in.
