Thermostat replace how to remove thermostat and what tools needed

Most thermostat bodies are usually quite easy to remove. For tools a decent socket set with extension bars and flex joints will be needed. Depending on how the hose clamps are fastened you will need a small socket, a flat blade screwdriver or a large pair of grips.
The only issue you might have is getting to the thermostat housing as I think it is tucked under another radiator hose. As your draining the system anyway you will be safe to remove it for access.

I hope were talking about a Ford V8,
Just follow the top radistor hose back to the engine block.
There should be 2 "7/16" bolts and a housing.
You shouldn't have to remove the hose in most cases.
loosen the two bolts,MAKE SURE ENGINE IS COOL.
At the bottom of the housing is the thermostat it should be resting on the engine block.
remove and replace it with the new one in the same direction with the spring down in the engine block.
Male sure you remove all the old gasket and put in a new gasket.
If you need a gasket sealer "used with most fiber type gaskets" use the gasket sealer.
If it happens to be a rubber "O" ring type gasket, no sealer is required.
Good luck,Gary.
PS. please rate my answer.

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.

THE EASIEST WAY TO REPLACE THIS RADIATOR IS TO REMOVE THE FREON FROM THE AC SYSTEM, DISCONNECT THE LINES GOING TO THE AC CONDENSER, REMOVE THE FAN SHROUD TOP AND BOTTOM, THEN REMOVE THE 13MM BOLTS ON THE UPPER PART OF THE RADIATOR SUPPORTS. REMOVE THE AIR DIFLECTOR ON THE BOTTOM OF THE VEHICLE, REMOVE THE AIR FILTER ASSEMBLY. LAST YOU NEED THE TOOL TO DISCONNECT THE TRANS LINES. ONCE THIS IS DONE THE RADIATOR AND THE CONDENSER WILL COME OUT IN ONE PIECE. AFTER THIS IS DONE YOU CAN EASILY REMOVE THE RADIATOR FROM THE SUPPORT.
IF YOU DO NOT HAVE THE TOOL TO REMOVE THE TRANS LINES YOU CAN UNSCREW THE TRANS LINES FROM THE RADIATOR. YOU WILL HAVE TO REMOVE THE FITTINGS OFF THE NEW RADIATOR AND USE THE OLD ONES. ONCE YOU HAVE THE RADIATOR IN PUT THE FAN SHROUD BACK IN AND TIGHTEN THE BOLTS. THEN IF YOU HAD TO UNSCREW THE TRANS LINES DUE TO NO TOOL, REMOVE ONE OF THE FITTINGS OFF THE NEW RADIATOR AND SCREW THE OLD FIITING BACK IN AND TIGHTEN IT. THEN REMOVE THE OTHER TRANS FITTING AND SCREW IT IN USING THE OLD FITTING. DO NOT REMOVE BOTH OF THE TRANS FIITINGS ON THE NEW RADIATOR AT THE SAME TIME OR YOU WILL LOSE THE RESEVOIR IN THE RADIATOR. ONCE THIS IS ALL DONE EVACUATE THE AC SYSTEM, RECHARGE THE AC, FILL THE RADIATOR WITH COOLANT AND YOU SHOULD BE GOOD TO GO. I HIGHLY RECOMMEND REPLACING THE RADIATOR, THERMOSTAT, AND THE RADIATOR CAP AT THE SAME TIME. I BELIEVE THE THERMOSTATS IN THIS VEHICLE DO NOT OPEN AS DESIGNED WHICH CREATES VERY HIGH PRESSURE IN THE COOLING SYSTEM WHICH CAUSES THE RADIATOR TO FAIL PREMATURELY.
AFTER STARTING THE VEHICLE CHECK THE UPPER RADIATOR HOSE AND MAKE SURE IT IS NOT ROCK HARD, IF YOU DID NOT REPLACE THE THERMOSTAT. IF IT IS ROCK HARD REPLACE THE THERMOSTAT.
THINGS TO CHECK:
CHECK THE RAD/CONDESER SUPPORTS FOR CRACKS YOU MAY FIND THEY ARE BROKEN IF THEY ARE REPLACE THE SUPPORT. IT IS AVAILABLE FROM FORD.

The thermostat should be located in a housing at the end of the upper radiator hose with two maybe three bolts. loosen the clamp if you have a tool to do this with, sometimes they're not screwdriver type clamps, may need to buy a tool for this job. once the upper hose is removed then you can loosen the housing and remove the thermostat. remove the old seal and replace it as well. the seal may be a gasket, if it is then scrape the surface clean. if you use sealant make sure you use it to glus the themostat and gasket to the thermostat housing ,not getting any sealant in the waterjacket, for it will circulate thru the system and stop up the block or even you're new thermostat. bolt the housing down equally on the bolts, don't warp the housing, replace the upper haoes, ( use a little grease around the inside of the hose to help seal and go on easier, tighten the clamp, replace coolant with the correct amount of 50/50 solution for your type car, you're finished, Good Job!!!

Thermostat replacement on 3.4 liter, Not the thermostat housing is between the Throttle body and exhaust crossover. If you have small haves and the right tools you can remove the two botls without removing the crossover and throttle body. The bottom bolt to the thermostat does not have to come all the way out, there is a cut out on the housing so you can slid it out. Good luck and take your time.

1. Remove the air cleaner and duct assembly.
2. Drain the coolant until the coolant level is below the thermostat.
3. Remove the crossover exhaust pipe.
4. Remove the radiator hose from the thermostat housing.
5. Remove the thermostat housing bolts and clean any sealer from the bolt threads.
6. Remove the thermostat housing and gasket.
7. Remove the thermostat.
8. Install the thermostat.
9. Install the thermostat housing bolts and tighten them to 18 ft. lbs. (25 Nm).
10. Install the radiator hose to the thermostat housing.
11. Install the crossover exhaust pipe.
12. Install the air cleaner and duct assembly.
13. Good luck...
    
14. Fill the cooling system.
15. Install the thermostat housing and gasket.
16. Clean the mating surfaces.

A car can overheat for a lot of reasons.First make sure this is the problem by checking the radiator hose or water level. Open the radiator cap when the car is cold, crank it, and then watch the water level. If it drops when the car warms up this is not the problem.
The tools you will need will depend on what you have to take off to get to it. If you can access the thermostat you should only need a ratchet or wrench to remove it and something to scrape off old gasket with.
Location:The thermostat should be inside the thermostat housing on the motor. Follow your top radiator hose to the place where it goes into the motor. There should be a sort of dome shaped housing there with probably a bolt on either side of it.The thermostat is inside that.
This is a reasonably easy job, but shouldn't be done carelessly. It's also kind of messy.
When the car is cold remove the bolts from the housing with a ratchet. Lots of coolant and water will drain out. But the thermostat will be visible.Pay attention to which side of the thermostat is up.It should just lift up. Remove all the old gasket from around the area and clean it up well. Replace the thermostat and gasket then the bolts. Be very careful not to over tighten the bolts or the housing will be ruined.
