2000 V6 Toyota Solara thermostat replacement

You probably have the iron block 3VZ V6, on which the thermostat is located in the water pump housing, under the water inlet. All this is behind the timing belt cover, so think about what stuff can be wisely replaced, if all that has to be taken off.

If the alloy block 1MZ V6, it is more conveniently located on the outside of the engine, in the water inlet where coolant comes from the bottom of the radiator up to the block.

4.8L, 5.3L and 6.0L Engines To Remove:
CAUTION
The thermostat is not serviceable separately. The thermostat housing (water pump inlet) and thermostat must be replaced as an assembly.

THERMOSTAT REMOVAL

HINT: Removal of the thermostat would have an adverse

effect causing a lowering of cooling efficiency. Do not remove

the thermostat, even if the engine tends to overheat.

1. DRAIN ENGINE COOLANT

2. REMOVE AIR CLEANER CAP WITH AIR CLEANER

HOSE

3. DISCONNECT ECT SW1TCH CONNECTORS

4. DISCONNECT ENGINE VIRE PROTECTOR FROM

WATER INLET AND RH CYLINDER HEAD

Remove the 2 nuts, and disconnect the engine wire

protector from the water inlet and cylinder head.

5. DISCONNECT WATER INLET PIPE FROM WATER

INLET AND LH CYLINDER HEAD

a) Remove the bolt and disconnect the inlet pipe from the

water inlet.

b) Remove the O-ring from the inlet pip e.

6. REMOVE WATER INLET AND THERMOSTAT

a) Remove the 3 nuts, water inlet and thermostat.

b) Remove the gasket from the thermostat.

INSPECTION

INSPECT THERMOSTAT

HINT: The thermostat is numbered with the valve opening

temperature.

a) immerse the thermostat in water and gradually heat the

water.

b) Check the valve opening temperature.

Valve opening temperature: 80 - 84CC (176- 183 deg f)

If the valve opening temperature is not as specified,

replace the thermostat.

c) Check the valve lift.

Valve lift: 10.0 mm (0.394 inch) or more at 95CC (203 deg f)

If the valve lift is not as specified, replace the

thermostat.

d) Check that the valve is fully closed when the

thermostat is at low temperatures (below 40CC (104CF)).

if not dosed, replace the thermostat.

INSTALLATION

1. PLACE THERMOSTAT IN WATER PUMP

a) Install a new gasket on to the thermostat.

b) Align the thermostat jiggle valve with the upper stud

bolt and insert the thermostat in the water inlet

housing.

HINT: The jiggle valve maybe set within 15 deg of either

side of the prescribed position.

2. INSTALL WATER INLET

Install the water inlet with the 3 nuts.

Torque: 8.0 Nm (80 kgf-cm, 69 inch lbs.)

3. INSTALL WATER INLET PIPE

a) Install a new O-ring to the water inlet pipe.

below the intake hose RH side of the engine. You will see the lower radiator hose running to it. let me know if u need more info!! Hopefully this helps!!

your lucky ,if they offer that amount take it ,was the car insured ??? know what i mean ------ sorry your car was stolen

Almost the same, minor differences.

You take out the battery, and the air-filter housing to give extra working space.
Then push in the starter motor to its place, and hand-tighten all its bolts.
Wrench tighten the starter bolts to the engine 38.ft-lb
Connect the solenoid wire, and tighten to 10.ft-lb
Connect the battery positive cable, and tighten to13.ft-lb.
Replace the air-filter housing.
Replace the battery, and terminals.
Crank-up the car.

You're going to lose some coolant, so have a bucket or other container ready. Follow the upper radiator hose to the point where it's connected to the engine. The hose is clamped to a metal housing 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.

Locate the top radiator hose. Follow the hose to the housing that is bolted to the engine. Remove the bolts and the thermostat will be revealed. Since the thermostat is directional, notice how it sits in the housing, or in the water jacket inlet. This is exactly how the replacement should go back. Before installing, make sure that both surfaces are clean and dry, (the housing and the inlet). If a gasket is required, make sure you have one. If not, some silicone gasket is ok.

its at the end of the coolant inlet pipe lower LH side of the engine. This pipe is below the alternator running from the lower radiator hose to the thermostat housing on the engine. Replace the O-ring at the end of the pipe if you are replacing the thermostat. There are 3 bolts holding the thermostat housing to the engine block. Hopefully this helps!! please rate...thanks!!
