hermostat, Replace My database showed this for thermostat removal, if database is wrong, my bad. 1. Remove coolant expansion tank cap. 2. Raise and support vehicle. 3. Open radiator drain petcock and drain engine coolant into a suitable container. 4. Close radiator drain petcock and lower vehicle. 5. Remove upper engine cover. 6. Remove protective shield from under engine. 7. Detach and remove air intake tube from throttle body and air filter housing. 8. Disconnect electrical and vacuum connections from intake manifold and its attached components. 9. Remove fasteners at bottom of intake manifold and at connection to cylinder head. 10. Remove intake manifold. 11. Disconnect hoses from thermostat housing. 12. Disconnect coolant temperature sensor electrical connection. 13. Remove thermostat housing from cylinder head. 14. Remove thermostat and gasket from thermostat housing cover. 15. Reverse procedure to install, noting the following: a. Install new thermostat housing gasket. b. Torque thermostat housing bolts to 88 in. lbs. c. Torque intake manifold bolts to 13 ft. lbs. d. Fill and inspect coolant level.

The thermostat on the 2001 Isuzu Rodeo 3.2L v6 is located on the top of the engine under the upper intake manifold. In order to replace it you will have to depressurize the fuel system by running the engine with the fuel pump fuze removed until the engine dies and then carefully remove the fuel rail and injectors. Then remove the intake manifold which will give you access to the coolant nozzle fixture attached to the top of the engine. The thermostat is in the top of the engine block under the nozzle fixture. Be sure to replace the thermostat with the proper replacement part (may be difficult to find) and put on new gaskets for the intake manifold before replacing it.

Trace the upper radiator hose to the mounting area on the intake manifold. Loosen the hose clamp on the manifold end of the hose and remove the hose. Pull the thermostat out of the intake manifold.

Hello ,

The thermostat is located on the right side of the engine looking in,between the intake manifold and the air filter box, underneath the wiring. This is in a 1994 Ford Probe GT 6 cylinder.

To replace the thermostat, you really need to remove the intake manifold and this can be up to two or three hours work alone, even for a qualified mechanic.

It is in the housing at the engine end of the upper rad hose. When replacing it make sure the spring on the thermostat is toward the engine.

NOTE: Remove the air intake box so you can see below. There is a pipe running right into the bell housing where the thermostat is housed. There is one bolt that you need to remove (it is to the right,below the distributor) Then there are the other 12 mm bolts on the bell of the thermostat housing to remove. After removing those the thermostat should be able to come right out.

Thank you, hope this helps you out.

Remove the bolts that hold the thermostat housing onto the intake manifold of the MR2 with an adjustable wrench and pull up on the thermostat housing to remove it from the intake. The housing is still connected to the hose. Lift the thermostat housing and the hose up to drain the antifreeze back into the radiator.

2 Remove the old thermostat from the hole inside of the intake manifold and replace it with a new one. Pull the thermostat gasket off of the top of the intake manifold and wipe the manifold clean with a towel.

3 Place a bead of RTV gasket maker around the bottom edge of the thermostat housing and allow it to dry for 15 minutes. Place the thermostat housing back onto the intake manifold and bolt the housing back into place. Allow 15 more minutes of drying time and slightly tighten the bolts again. This will form a solid seal between the intake manifold and the thermostat housing.

Please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat . These are generic instructions. specific instructions for your car are provided below. please get back to me with any questions.

Colt and 1990-91 Vista

1. Disconnect the negative battery cable.
2. Drain the cooling system to a point below the thermostat level.
3. Remove the air cleaner.
4. Disconnect the hose at the thermostat water pipe.
5. Remove the water pipe support bracket nut.

This nut is also an intake manifold nut. It is very difficult to get to. A deep offset 12mm box wrench is used to remove or replace it.

1. Unbolt and remove the thermostat housing and pipe.
2. Lift out the thermostat. Discard the gasket.

To install:

Fig. Fig. 1: Thermostat - 1990-92 Colt Hatchback. The 1.6L is 1990 only

1. Clean the mating surfaces of the housing and manifold thoroughly.
2. Install the thermostat with the spring facing downward and position a new gasket. The jiggle valve in the thermostat should be on the manifold side.
3. Install the housing and pipe assembly. Torque the housing bolts to 11 ft. lbs. (14 Nm); the intake manifold nut to 14 ft. lbs. (19 Nm).
4. Refill the system with coolant. Connect the negative battery cable.
5. Start the engine and check for leaks.

The thermostat is located in the front of the intake manifold under the thermostat housing, and follow the upper radiator hose over to where it connects to the engine on the intake manifold and that will be the thermostsat housing. remove the upper radiator hose from the thermostsat housing and remove the ground wire if there is one attaced to one of the two thermostat housing studs, and then remove the two studs/bolts from the thermostat housing and then remove the thermostat from the intake manifold. Be sure to replace the thermostat correctly and here is an image to help assist you.

THE 2.4 ENGINE THERMOSTAT LOCATED NEAR THE EXHAUST MANIFOLD YOU HAVE TO REMOVE MANIFOLD HEAT SHIELD TO GET TO IT. THE 3.4 AND 3.1 THERMOSTAT UNDER LOWER INTAKE MANIFOLD ON DRIVER SIDE.YOU HAVE TO REMOVE THROTTLE BODY UNIT AND COOLANT LINES HOOK TO IT TO MAKE EASIER TO REMOVE THERMOSTAT HOUSING TO REPLACE THERMOSTAT.

Mr. Lakewood,
The thermostat is in the housing at the end of the top radiator hose where it connects to the engine manifold. The thermostat housing is clamped onto the hose and is bolted to the engine manifold by two bolts.
1. Drain enough coolant from the cooling system to a level below the height of the thermostat housing.
2. Remove the two bolts and separate the housing from the manifold.
3. Remove the thermostat from the engine. You may have to pry it out if it is stuck. (Don't be alarmed if there is no thermostat. Some mechanics remove them for troubleshooting).
4. Scrape off the old gasket and sealant from the housing and the manifold.
5. Install new thermostat, pointy side towards radiator.
6. Use Permatex #2 (non-hardening sealant) on both sides of the new gasket and bolt down the housing.
7. Replenish cooling system.
8. Start engine, allow to warm up and check for leaks.
9 *done*

The Permatex #2 gasket sealant ($4 AutoZone) is in a small tube. One small tube is more than enough.

You need to remove the thermostat housing again. Then you will have to extract the bolts you broke off. You will need to drill and tap them so you can use an easy out to remove the broken bolts from the threads. Then you can clean up both mating surfaces and replace the gasket and the thermostat. Check to make sure you did not crack the thermostat housing or you may have another leak when finished. They are usually aluminum and break easily if too much pressure is applied or they are corroded and weak.
