Hi there, below are the removal/installation instructions for your thermostat.

REMOVAL:
  • Remove the air cleaner and duct assembly.
  • Drain the coolant until the coolant level is below the thermostat.
  • Remove the crossover exhaust pipe.
  • Remove the radiator hose from the thermostat housing.
  • Remove the thermostat housing bolts and clean any sealer from the bolt threads.

  • Remove the thermostat housing and gasket.
  • Remove the thermostat.
  • Clean the mating surfaces.

INSTALLATION:
  • Install the thermostat.
  • Install the thermostat housing and gasket.


NOTE: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
  • Install the thermostat housing bolts and tighten them to 18 ft. lbs. (25 Nm).
  • Install the radiator hose to the thermostat housing.
  • Install the crossover exhaust pipe.
  • Install the air cleaner and duct assembly.
  • Fill the cooling system.


Hope it helps

How do I replace the themostat?


The thermostat is usually located within the large radiator hose attached to the motor block and secured by 2 or 3 bolts to the motor. Remove the blots and you will find the thermostat inside, It requires a new gasket and make sure you put it in the same way you took it out. Tighten the blots tight after you change it or you could develop a leak.

Where is the thermostat located on a 2000 mazda 626 2.0L


The thermostat on the 2.0 is located on the right front of the engine. It is in the thermostat housing at the engine end of the lower radiator hose. According to the auto parts stores, there is a square thermostat gasket required, however, this is not correct. On the actual thermostat, there is just a rubber gasket that goes around the thermostat itself.

I need to change my thermostat on a 1999 chevrolet cavalier where is it located


Fig. 1: The thermostat is located in the lower radiator hose on the 2.2L engine

When adding coolant, it is important that you use GM Goodwrench DEX-COOL® (orange colored, silicate free) coolant meeting GM specifications. On these vehicles, if silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner; at 30,000 miles or 24 months.
  1. Disconnect the negative battery cable.
  2. Properly drain and recover the coolant until the level is below the thermostat.
  3. Unfasten the coolant outlet-to-inlet manifold attaching bolt and nut, then remove the outlet.
  4. Remove the thermostat. Clean the inlet manifold and outlet mating surfaces.

To install:
  1. Install a new O-ring onto the thermostat
  2. Place the thermostat in the inlet manifold.
  3. Attach the coolant outlet to the inlet manifold, using the bolt and nut. Tighten to 89 inch lbs. (10 Nm).
  4. Refill the engine cooling system.
  5. Connect the negative battery cable, then start the engine and check for coolant leaks.
Hope this help (remember rated and comment this).

I can not locate the thermostat on a 1999 vw passat


Hi:
The thermostat on your car is located under the thermostat housing. This is located on the engine and your upper radiator hose is connected directly to it. If you are wanting to change it, start with a cold engine, and first drain your coolant out of your radiator, then disconnect the radiator hose from the thermostat housing, remove the bolts that attach it to the engine, and carefully remove it. The thermostat can be removed and the new one installed. Remember to scrape off all gasket residue, and install the new thermostat with a new gasket. Reconnect the upper radiator hose, then fill the engine back up with coolant. Start the engine, and let it warm up and check for leaks!

Where is the thermostat located in my 1994 caprice classic?


To locate the thermostat follow the upper radiator hose to the point where it enters the engine. The thermostat is located below the coolant inlet that the hose is connected to.

To change it:

You're going to lose some coolant, so have a bucket or other container, and some fresh coolant ready. Follow the upper radiator hose to the point where it's connected to the engine. The hose is clamped to a metal housing (water inlet) which is bolted to the engine. Remove the bolts (not the hose) and lift the housing to expose the thermostat (may require a little prying with a screwdriver or similar tool). Note how the old thermostat is fitted (which end is up), lift it out of the engine, and then remove all traces of gasket from the housing and the engine. Install the new thermostat and gasket, replace the bolts, add coolant as necessary, and you're done.

Before you start the job though, check the condition of your upper and lower radiator hoses. If they show any signs of wear, fraying, or fatigue, you might as well replace them too.

Changing thermostat in 2004 Rendezvous


The dealership will charge around $450 to change the thermostat on the 3.4L engine.
You have to remove the crossover exhaust manifold. Once that is out of the way, the thermostat itself is easy. Before the manifold is removed, I could only touch one of the two bolts holding the thermostat housing in place, much less get a wrench on it.

If your engine is the 3.4L then the instructions below will work:

REMOVAL: - Remove the air cleaner and duct assembly. - Drain the coolant until the coolant level is below the thermostat. - Remove the crossover exhaust pipe. - Remove the radiator hose from the thermostat housing. - Remove the thermostat housing bolts and clean any sealer from the bolt threads.

- Remove the thermostat housing and gasket. - Remove the thermostat. - Clean the mating surfaces.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified.

Need location of thermostat ,over heating.


If you follow the top hose from the radiator to the motor you'll notice a housing where the hose meets the motor. Disconnect the hose and remove the two bolts holding the housing in place. Remove the housing and the thermostat is underneath. When you replace it make sure the old gasket is completely removed and replaced with a new one. If pieces of the old gasket remain you will nto get a good seal and will eventually end up with leaks.
