Actually, I did whatnyou mentioned above, however, when I put the gasket and sealant on and reconnect the three bolts, it leaks. What could I be doing wrong?
Expert:  lostrider replied 8 years ago.
Are you using a paper gasket or a rubber O-ring to seal the thermostat housing?
Customer: replied 8 years ago.
I am using a paper gasket. Rubber seems like it would be better. But, this is what the auto-parts store have in-stock for my make/model/year.
Expert:  lostrider replied 8 years ago.
Thats where the problem lies, That thermostat housing uses a rubber O-ring to seal the thermostat, when you removed the old thermostat there should have been one on the old thermostat, it is not reusable and needs to be replaced with the new thermostat. Here is the Ford part number for the thermostat that the parts house might be able to cross to ensure you get the right parts.

I have to tell you that I went to two different parts dealers and they both had in-stock a paper gasket for my make/model/year. In addition, I removed a paper gasket that was previously on the housing. Do you think maybe that I'm placing the thermostat in wrong?

can I get the 17 digit vin number to your car to check the engine code?

Customer: replied 8 years ago.
My VIN is IFAFP53U82G112000.
Expert:  lostrider replied 8 years ago.
Thank you for the reply, I have checked the vin number and the engine is a U code engine, all the service manuals that I had accessed is saying there is an o-ring, but since you pulled a gasket from yours I believe the manuals are misprinted, so heres goes, need to make sure the mating surfaces are clean on the engine and the t-stat housing, insert the thermostat into the housing with a slight twist, the thermostat should stay seated in the housing, apply a small amount of sealer to the housing and stick the gasket to it and then install it on the engine and tighten the retaing bolts evenly, then see if it still leaks then.
