How do you change a thermostat in a 1995 Toyota Corolla
You will need a couple of tools, and they are ratchet, and extension, and some metric sockets, a scraper, and a flat tip screw driver. I do have a question, before going to the auto parts store, are you hoses 3 years or older? If so, change them now also. Now lets get a new thermostat, gasket, and gasket sealant. If changing hoses, 2 hoses, 4 hose clamps,and coolant. Now, remove the upper radiator hose at the engine( this is the thermostat housing cover). now, remove the 2 bolts securing the cap to the engine block. now, gently pry up the housing and stop. turn the cap over and scrape it clean, to shiny metal. now do that at the engine block. Clean, great(you don't want any way for the cap to leak), now trade out the thermostats(I had you leave the old one in for cleaning, to keep anything out of the engine), now take some gasket sealant and put a thin coat around the engine block where the gasket goes. take the cap and do the same. place the gasket on the engine block, and carefully set the cap back on. put the bolts back in and connect the hose. and you are done. about 30 minutes for a beginner. another 20 to change the hoses and and fill with coolant and water. start the car, and let it warm up, wait for the thermostat to open. (you can buy a new one, that is broken. it happens) check for leaks. No leaks, great job
