Reason for thinking this is, I DO have a leaking clutch master cylinder and am finding fluid on the ground under the center of my car ('04 SVT, 107,000 miles). It feels and smells more like brake fluid than coolant. Looking up under the car, the fluid is running down the passenger side of the bellhousing, starting at a point directly below that darned plug. And the plug appears to be moist, as well. But wouldn't know what would be above the housing that would drip/leak??

Also, regarding the clip that holds the plug in, do you access it from below the car? And which way does it pull (to the front? towards drivers side, etc.?)

Suggestions? Slave cylinder is on the driver side of the housing, correct? And it wouldn't necessarily leak out the front by the plug, would it? I do have a master cylinder on order.

I seem to be having the same two issues as you. Did yours start after and during that really cold spell that we had here in TX? These issues are so annoying. How much is it in labor if I bring the rubber rings to a shop and have them replace it for me?

I have some sort of coolant leak but it doesn't leave a puddle. I checked around the housing and I can't see any visible coolant. I smell it after the car has been driven.

Is it possible that plug/sensor area is leaking and I can't see it? I haven't looked at it from the bottom yet.

Where the tstat housing mates to the block, it's dry. I might reach under the housing when I get home from work and check for any leaks.

I recently did this fix on my car, so I have some extra o-rings. If you shoot me a PM with your address, I'll drop one in the mail to you for FREE! I figure that's the least I can do for all the help I've gotten from members on FF.

I think I have a similar issue. Found a small puddle under the car while in the shop the other day. It was under the car on the front passengers side. Not sure what it was so I took a small taste, lol. Sweet tasting. So I figured yup antifreeze. Noticed the antifreeze was low but wasnt sure about where it could be leaking from. Great info here. Hope this is my problem.
Cheers

plug o ring and temp sensor o ring - on SVT

anyone know if the o ring for the sensor (on the top of the housing) is the same size as the plug (on the underside - that has a leakage issue)?

both my plug and sensor have a leak. the Plug large, the sensor only very slight.

Same leak in Ztec engine - what should be changed?

Hi Guys, I found this thread as I am looking for an answer to my son's Ztec engine which is losing coolant. So I am raising it from the big sleep.

I see the wetness around his thermostat housing so know this is the root of the problem. I figured I need to change the pesky o-rings to the better ones, but I see that the plug everyone speaks about is just on the SVT engine.

What then is causing the problem with the Ztec engine if I don't have the o-rings to begin with? Is it just the big o-ring that seals the thermostat/housing? Or is it the housing itself? Thanks for any help.

t stat housing failure

OK, I know this has been to death. My daughter lives away and had her 2001 ZETEC t stat housing replaced several years ago. Now it's leaking again, and looks like it got damaged by oil from a leaky valve cover gasket. I'll be installing a new housing and valve cover gasket next week, but here is the suggestion:

IF the housing o ring is being damaged by oil why not protect it? I'll be making a paper gasket and coating both sides of it with high quality sealant (yamabond) to place between the housing and block. The o ring will still do the water sealing - the gasket and sealer will PROTECT the o-ring.

Any thoughts? I won't know if it "works" for 2-3 years!

If you think your housing is leaking check the thermostat outlet first (three torx screws on FRONT of housing). Dealer put the last housing on the car and one of the t stat screws was loose - hardly finger tight. I drained the coolant, pulled the big hose, removed the three screws, replaced the stat and stat seal and the leak is fixed. Now I have an extra housing I know I'll need later anyway. I am working with a guy that makes similar parts for motorcycles and I'm trying to talk him into making this part for the ZETEC. My local dealer (fairly small town) sold 200 housings last year. There are days when he sells 1 per day. That's CRAZY.

There are still around 4,000 Ford dealers in US. If each one averages 50 of these per year that's 200,000 housings per year. Nuts. You KNOW they make more than 5 bucks on this so it's at LEAST 1 million in profit.
