Location of engine thermostat - 2000 Lincoln LS

In a 1999 Toyota RAV4, the thermostat is located in the engine compartment, near the top of the engine block. It is typically located on the passenger side of the engine, near the front of the vehicle. To access the thermostat, you will need to remove the plastic engine cover.
To replace the thermostat, you will need to drain the coolant from the engine, remove the hose that connects the radiator to the engine, and then remove the mounting bolts for the thermostat housing. Once the housing is removed, you can access the thermostat and remove it. Be sure to refer to a repair manual for specific instructions, as the process may vary slightly depending on your vehicle's specific model and year.

Hi,

Your engine must be cold before removing the thermostat.

Find the location of your thermostat by following the rubber hose located on bottom of your radiator (passenger side) to the point where it attaches to the engine. Remove the two bolts at that location and you'll find your thermostat nestled in there.

Be sure to place a pail under the car to contain the coolant.

Thermostat Operation:

The automotive thermostat is a temperature controlled on and off valve. When the temperature rises to a predetermined temperature, the thermostat opens up to allow the engine coolant to flow through the cylinder block and the radiator. This flow is crucial to maintain optimum operating temperature for fuel efficiency, enhanced driveability, and engine protection. The coolant flow is reduced when the engine is cold, and the flow is increased when the engine is hot. Contrary to popular opinion, operating the vehicle without the thermostat doesn't make the engine run cooler. It will actually run hotter because there isn't a thermostat to slow the coolant flow. This means the coolant doesn't stay in the radiator long enough to dissipate its heat.


All the best

Your thermostat is located on the the intake manifold of your engine.

-Locate the upper radiator hose.
- Follow it to where it meets the engine.
- The fitting the upper radiator hose is attached to is the thermostat housing.

If you remove the thermostat housing, you will find the thermostat nestled in nicely underneath.

The thermostat is located inside the thermostat housing. To find it follow the upper radiator hose to the engine block.
Depending what size of engine you have the location is different.
The thermostat on this vehicle's (the Envoy & Trailblazer are essentially the same vehicle) In-line 6 cylinder engine is on the driver's side of the engine, below & behind the alternator.
If you have a V8 cylinder engine is in front of engine see the picture. Item 303 thermostat housing, 305 thermostat, and 304 thermostat gasket.

THERMOSTAT ON THE 4 CYLINDER ENGINES IS LOCATED ON THE DRIVERS SIDE OF THE ENGINE AT THE BOTTOM OF THE WATER PUMP.THERMOSTAT ON V-6 ENGINES IS LOCATED ON THE FRONT OF THE ENGINE BLOCK.

The thermostat is located on the engine block, where the upper radiator hose connects to the engine. You'll see a large elbow-like component that is attached to the engine with 2 bolts.
Just follow that upper radiator hose and you got the location. When you remove that housing (elbow-like component), you'll see the thermostat.
Make sure you note which end of the thermostat is up and which end is down. Don't reverse the install.

GM Corsica/Beretta 1988-1996 Repair Guide
The thermostat is located inside a housing on the back of the cylinder head. It is not necessary to remove the radiator hose from the thermostat housing when removing the thermostat.

CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

follow the upper water hose from the radiator to the engine, thermostat is where the hose stop. you will see 3 bolts holding down a semi-round object. unbolt it, the themostat is under neath.

Thermostat is located on 4.0L I-6 on front cylinder head. The 3.7L V-6 thermostat is located where the lower radiator hose attaches to engine. The 4.7L V-8 thermostat is located where the lower radiator hose attaches to engine. The 5.7L V-8 thermostat is located where the upper radiator hose attaches to engine. The 3.9L V-6 and 5.9L V-8 Thermostat is located on front top of intake manfold (between alternator and ac compressor)
