Here's an old thread that illustrates very well what he's talking about http://www.focusfanatics.com/forum/s...g+coolant+leak My understanding is this plug is only present on thermostat housings for SVT cars and it should be easily visible when viewing the housing from above. I had a steady leak there and just fixed it, slathered the seal area of the plug with thermostat/housing friendly gasket maker stuff, and also used some on the seal area between the thermostat and cylinder head. You'd have to pull the housing off the car to inspect it, but this would give you a chance to inspect everything else.

From what I've read the common failure on non SVT cars is the o-ring seal between the cylinder head and thermostat housing, conventional wisdom is oil can leak from the valve cover and contaminate the seal, causing it to swell and then crack the housing itself.

I think you need to figure out exactly what you've got and proceed from there. I'm a cheapskate so I decided to fix what I have, but the gasket putty stuff I mentioned takes 24 hours to completely cure depending how cold out it is. It's cold as hell here so I waited a full 24 hours before reintroducing coolant to the system.

In short, if you have alternate means of transportation I'd take out the whole thermostat housing and inspect it and proceed from there.

Because they made the housing out of cheapo plastic it cracked around the neck ALL the time.

Trick to finding a coolant leak is find the highest point where the fluid is coming down and right above or on that part is where its coming from.

Gravity has helped me solve all my fluid leaks. Lol

there are a few companies that full aluminum versions but will run you $100+ on those housing. But then you never have to worry about it again. Why companies use plastics in the cooling system in beyond me.... every cooling issues I have ever had has been directly related to a plastic part failing.

Here is a very easy how-to that I used when I changed the housing from a coolant leak. I just replaced it with another plastic housing, but I got the part for $40.00 so why not lol

This is the one I bought:
http://www.pepboys.com/product/details/222077/

It came pre-assembled, all I had to do was drop it in! I actually paid $47.99 for it. Go to PepBoys and give them this part # 902-201 They usually keep one in stock. Just be sure to get what you asked for, I had to deal with a lot of stupid clerks from a few different parts chains because they all thought the housing was just the water outlet.

For the best price on an upgraded housing go here:
http://forums.focaljet.com/tousley-f...svt-zetec.html

PM FORDSVTPARTS aka Steve and ask for the upgraded Zetec housing.

Steve's housings are the metal Contour housings. They will cost you about $100.

The only other so-called "upgraded" housing is on CFM's website, but they say nothing about the housing itself, they just say that the bolts are upgraded.

If you want the best, I would go with Steve.
