mikeshoup Posted February 10, 2006 Share Posted February 10, 2006 I don't know where the thermostat housing is on your car (I don't own an EA-82 car, I have an XT6), but the steps are fairly simple: Drain the coolant Take the bolts off the thermostat housing Remove the old thermostat, and the thermostat gasket Put the new thermostate and gasket in the same way the old one came out put the thermostat housing back together Fill it back up with coolant Not too difficult... Google's really helpful on these simple things. Here's a link to some directions found on google. Seem to cover everything. Maybe somebody can correct me on anything?

Caboobaroo Posted February 10, 2006 Share Posted February 10, 2006 If you follow th top radiator hose, it'll go into a fitting on the engine (actually the intake) and there are two bolts that hold this fitting onto the engine. Those two bolts hold on the thermostat housing and inside is the thermostat. Quote Link to comment Share on other sites More sharing options...

How do I drain the coolant? Quote Link to comment Share on other sites More sharing options...
mikeshoup Posted February 10, 2006 Share Posted February 10, 2006 D'oh, its easy to do. Remove radiator caps Place a bucket or something to catch the coolant under the drain plug on the radiator Remove the drain plug, and wait. Filling back up is, you guessed it, the opposite. Put the drain plug back in Pour the mix of 50/50 until at max Keep the radiator cap off, start the engine, let it warm up and watch the coolant swirl and the level drop Top off the coolant Put the radiator caps back on.

91' loyale Sub Posted February 10, 2006 Author Share Posted February 10, 2006 ahhh yes of course, thats all rather intuitive, but I guess i shuold have been more straight forward and asked where the drain plug is? This is the last of my lame questions I promise. Thanks Quote Link to comment Share on other sites More sharing options...
mikeshoup Posted February 10, 2006 Share Posted February 10, 2006 On the bottom of the radiator Quote Link to comment Share on other sites More sharing options...
hooziewhatsit Posted February 10, 2006 Share Posted February 10, 2006 the drain plug will be on the bottom passenger side of the radiator. Also, you don't have to drain all the coolant to change the thermostat. But I would recommend it if you haven't changed the coolant in a while. If you take the rad cap off it will also greatly speed up the draining process. edit: make sure you put the new thermostat in the same way that the old one came out, ie, spring going down.
