Re: step by step for thermostat replacment
Changing the thermostat is a pretty easy task. I don't have pictures for you though.
You'll need:
-Thermostat
-Thermostat seal (A rubber o-ring that goes around the t-stat. You shouldn't need an actual gasket, though there are gaskets you can get.)
-10mm socket, also an extension will probably help
-You will likely need a bit of coolant or water to top off the system when you are done.
-First you can either drain a little bit of the coolant, or you can loosen the bolts and let whatever comes out comes out, it won't be much.
-There are two 10mm bolts on the sides of the thermostat housing, remove those and move the housing out of the way. (To avoid losing any more coolant it'd be helpful to note to keep the housing end higher than the top of the radiator.)
-The thermostat will be directly under the housing and you can simply pull it out and replace it with the new one.
-There's no specific orientation for the thermostat besides top/bottom. Just make sure you put the new one in the same way, which would be with the spring side down.
-Put the thermostat housing back on and replace the bolts and tighten.
-Now you'll want to top off the coolant and run the car.
-To help air out the system open open the bleeder valve on top of the housing (It will either need a flathead screw driver or a 7mm IIRC) and with the car running and up to temperature, open the bleeder valve and let the air bubbles out. Wait until there is a steady flow of coolant coming out then shut it and you should be good to go.

99, you really need to read the forum section descriptions before you post. This is the second topic of yours moved today, and there have been others previously.
Moving to the proper section.
