How do you replace thermostat for a 1990 camaro rally sport?

Answer 1

There is a little metal box on the front of the raiator not larger than 2" on each side (if you have the replacement thermostat you should know the general size, the box is barely bigger than the thermostat). There are two bolts on the front of the box, remove them, then the casing can be removed. Now you simply need to lift out the old/broken thermostat and place the new one in. Then of course put the casing back on and bolt it back in place! Then you should be good to go. Hope this helps someone. You need to be more specific and include year and motor information.

Generally though, the t-stat is at the top of the motor where the upper radiator hose connects to the block. It is usually only two or three bolts to remove the housing and replace it. Do replace the gasket too.
