Thermostat Housing Leak

2003 ZX3. 123K miles

I have a really bad thermostat housing leak. I also have a valve cover gasket leak. I want to replace both and some questions.

I plan to use the Dorman 902-201 kit to replace the housing kit. What else should I buy to make the repair? Do I need a coolant sensor?

As far as the gasket - Will an OEM one be okay, os should I get an aftermarket one?

Thanks

Nothing, providing you have the appropriate metric socket and wrench sizes. Re-use the thermostat.

No. Your car has a engine temp sensor that doesn't contact the coolant directly; it's located at the back of the cylinder head by the alternator. The SVT version of the Zetec engine has the sensor in the T-stat housing.

OEMs are generally superior in terms of fit compared to after market ones, imo; either should be fine for such a simple part. Shouldn't be more than $35 - 40. Torque the valve cover down evenly starting at the inner bolts and working outwards in a circular (one adjacent side then the opposite) sequence. Don't over torque.

I'm fairly sure that the T-housing uses a 10mm and the valve cover uses an 8mm... or something like that... but just buy a set of metric wrenches and sockets, they will be worth it in the long run...

I cannot highlight this right here enough!!! I put to much into it on my 2000 zetec, snapped the bolt right off in the head, luckily for me in my case it was the bolt over the header so I was able to put a C-clamp on it to keep it from leaking oil...

On the bright side, If I ever want to smoke a honda, I can just take off that C-clamp and oil will drip onto the headers making LOTS of smoke flow out of the cracks of my hood and around through my fender wells

Anyone know the cheapest place to buy some Gold coolant? I understand that I have to use this coolant.

I have a Felpro valve cover gasket from a mid 90's Contour. It's nice and thick. It came with my valve cover from Massive Speed. I think they know a thing or two.

You may want to look over this thread: Motor Mounts - Duralast & Anchor Brand.

It appears that most people on this site recommend only using OEM replacements.
