It also makes it easier to pull the mass air flow off the whole assembly that goes into the intake and be carefull the bottom bolt on the thermostate houseing likes to break really easy

The thermostat is located in the housing bolted to the block that the lower hose is attached to.

-Remove the lower hose from the housing.
-Remove the two bolts holding the housing to the block (10mm socket will work).
-Remove the housing from the block.

The new thermostat will come with a cardboard tube. Use it to push down and twist the thermostat to release it from the housing. Install the new thermostat into the housing and then reassemble.

Fill the cooling system and start the vehicle. Let it idle until the cooling fan comes on making sure to top off the coolant reservoir as necessary. Then replace the cap and your good to go.

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

My heater only blows out cool air even when motor is hot. Fluids are full. Going to try to change out thermostat just need to know where its located.


you can change the thermostat. there are two hoses coming off the radiattor. one goes to the heatere core and to the engine block. the one to the block has the thermostat. take the old thermo and boil it in water. if it open up it is not the thermo. the next likely reason is th heater core. Please let me know

I need to know the location of the Thermostat on my 1996 Jeep Grand Cherokee,


If you have a V8 the thermostat is located under the coolant inlet tube. The tube is located on top of the engine, in the front about center. The thermostat is hard to change. Locate the upper radiator hose on your radiator and follow it to the engine block it is located on the top front part of your engine and you must lean over the front and look down onto the block to see the thermostat housing.

Changing a thermostat


Follow the big water hose on top of the radiator to the engine blogk. Where it goes into the block there should be 2 or 3 bolts to remove the housing. When you change the thermostat you should also change the gasket. I hope this helps.you.
