Car is getting hot

Pull apart the hose and housing. Put the housing on, and tighten down. Then reinstall and tighten the hose onto the housing. The housing should be free of all encumbrances when putting it on, so you get a good leak-free seal between the housing and the engine block.

Heater core might be half plugged that or need new thermostat ....

Hello: Follow the top hose coming from the radiator to the engine toward the drivers side. Remove hose from housing. The thermostat is under the housing. Here is where it gets tricky, steel bolts go into aluminum and have a tendency to freeze up, if you force them you may break them off. Do this before attempting to do the task. Get engine hot then spray with WD-40. Let soak a couple of days. If that doesn't work, again get engine hot, pour brake fluid around bolts and soak for a couple of days. You don't have to drain more than a couple of quarts out of the radiator to do this job.

Thermostat is here and the sensor is screwed into the housing:



Please let me know if you have more questions, and thanks for using FixYa.

i would say no thermostat has been fitted or changed or the wrong type will cause this as well ,these vehicles have a housing at the front which is plastic and one on the side ,well the thermostat is behind one of them depending on model and the thermostat has two shut off doors so to speak and if yours only has one then this is because your mechanic thought they could get away with a different stat that they had laying around from an american vehicle ,yes it fits in the hole but it blocks one way and opens another then when engine is hot one closes and the other opens allowing the water into the rad to cool it

REMOVAL & INSTALLATION
Gasoline Engines
CAUTION
Never open, service or drain the radiator or
cooling system when hot; serious burns can occur from the steam and hot coolant.
Also, when draining engine coolant, keep in mind that cats and dogs are
attracted to ethylene glycol antifreeze and could drink any that is left in an
uncovered container or in puddles on the ground. This will prove fatal in
sufficient quantities. Always drain coolant into a sealable container. Coolant
should be reused unless it is contaminated or is several years old.

1. Drain the radiator until the coolant is below the thermostat level (below
   the level of the intake manifold).
   
2. Remove the water outlet elbow assembly from the engine. Remove the
   thermostat from the engine, or, on the 4.8L, from inside the adapter elbow.
   To install:
   
   
3. Clean the gasket surfaces on the water outlet elbow and the intake manifold.
   Use a new gasket when installing the elbow to the manifold.
   
4. Install the new thermostat making sure the spring side is inserted into the
   engine, or, on the 4.8L, downward into the thermostat housing. Tighten the
   thermostat housing bolts to 20 ft. lbs. (28 Nm). On the 4.3L, 5.0L, 5.7L tighten
   the studs to 21 ft. lbs. (28 Nm). On the 7.4L tighten the bolts to 27 ft. lbs.
   (37 Nm).
   
5. Refill the cooling system. Start the engine and check for leaks.

Diesel Engines
1988-95 MODELS

1. Remove the upper fan shroud.
   
2. Drain the cooling system to a point below the thermostat.

3. Remove the engine oil dipstick tube brace and the oil fill brace.
   
4. Remove the upper radiator hose.
   
5. Remove the water outlet.
   
6. Remove the thermostat and gasket.
   
7. Installation is the reverse of removal.
   
8. Use a new gasket coated with sealer, Make sure that the spring end of the
   thermostat is in the engine. Tighten the bolts to 35 ft. lbs. (47 Nm) on 1988-91
   models and 31 ft. lbs. (42 Nm) on 1992-95 models.

1996-98 MODELS

1. Drain the cooling system to a point below the thermostat.
   
2. Disconnect the upper radiator (inlet) hose from the thermostat outlet.
   
3. Ufasten the thermostat housing bolt and stud, then remove the housing.
   
4. Remove the gasket and the thermostat.
   
5. Clean any remaining gasket from the thermostat hosing mating surfaces.

   To install:
   
   
6. Place the thermostat into position in the housing, then install the gasket.
   
7. Install the thermostat housing, the bolt and the stud. Tighten the bolt and
   stud to 31 ft. lbs. (42 Nm).
   
8. Attach the upper radiator (inlet) hose to the thermostat outlet.
   
9. Fill the cooling system.
   
10. Start the engine with the radiator cap still removed, until the upper
    radiator hose is hot (this means the thermostat is open).
    
11. With the engine idling, add coolant until the coolant level reaches the
    bottom of the filler neck.
    
12. Instal the radiator cap making sure the arrows line up with the overflow
    tube and check for coolant leaks.

you have to remove thermostat housing from under water pump to get to thermostat.you also need a haynes or chilton repair manuals.it will make job easy.finding and locating parts of the car.

Follow the upper radiator hose back to the engine until you see a hose clamp holding it to the engine block. This is the thermostat housing and should have bolts to pull it apart. The new thermostat installs with the spring toward the engine. When purchasing a thermostat, if you get one with a jiggle valve (a little piece of metal on the top that jiggles) it'll help you orient the new thermostat as the jiggle valve goes on top (the thermostat and housing aren't perfectly round so you have to rotate it until the thermostat fits into the housing correctly). You can use some spray adhesive to keep the gasket in place while installing the thermostat. This helps, but it not necessary.

yes a right *** to get to,remove everything in sight to get to the housing or you will crossthread the bolts on the housing

hi...just follow your top radiator hose from the radiator to the block. at the block where the hose ends is the thermostat housing. its in there..

thank u rate me!!
