where the thermostat belongs, but it should go back where and the direction it came out!
You need the exact model and year (there's at least four posiblities) of your car to find the correct directions.
These directions are typical:
- Clean off old gasket material, rust or scale
- Use a new gasket
- Install the thermostat into the housing in the same direction that the old thermostat was in. Then install the housing in place on the engine and tighten its bolts/screws.
- Re-install all the other parts and components in the reverse order of removal. On V6 engines, you'll need a new O-ring on the water inlet pipe; lubricate this O-ring with soapy water.
- Refill the engine coolant, making sure the drain plug is re-installed and the heater control is at the maximum heat position. Use fresh coolant if the old coolant is dirty or contaminated in any way; use a 50/50 mixture of coolant and water.
- Run the engine in a well-ventilated area with the radiator cap off until the thermostat opens; the coolant will start flowing and the upper radiator hose will get hot. Shut off the engine, wait for it to cool and more coolant mixture until it reaches the radiator filler neck lip.
- Bleed air from the cooling system on a V6 engine by squeezing the upper radiator hose; wear gloves when you do this, as the hose will be hot. Add more coolant as needed.

hello I have a question I have a 96 Toyota camry 4cly just got the head out shop to have it check put the head back on the car with new water new thermostate new radiator my lower hose not get hot and the car is run hot with the fan running need help look like there no flow going thru

ivan - For future reference you posted a Question in the place where only Answers belong. Please use the add comment link to the appropriate Answer, Question or create your own original Question. FWIW I think you have an air vapor lock. Have you read head replacement instructions for this car? Where did you find them? look specifically at '''Re-Assembly and though the year is different yours should be similar. Note the last step: Allowing the engine to idle for 1/2 hour with the radiator cap off can help remove air pockets.

Just wondering if the gauge coolant temperature sensor unit is OK or whether it may be the ECU coolant temperature sensor unit that is the problem.
If the gauge is reading high then try disconnecting the lead at the sensor (should be just one wire) and test using an Ohmmeter. Not sure what the resistance reading should be but with most sender units it is a high resistance value when cold and a low when hot.
Where is the temperature gauge sitting if you just turn on the ignition, without starting the engine, on a cold engine?
If you can determine the brand of the gauge sensor unit the specifications for it should be able to be found online.
If it tests OK then try the ECU coolant sensor, especially if the fan does not come on (make sure A/C is off) There are videos online how to do this. Do not confuse it with the gauge coolant temperature sensor. The ECU sensor usually has 2 wires connected to it and the gauge sensor only 1.
The ECU sensor "tells" the ECU to switch on the fan.
Be safety aware and ensure that the engine is switched OFF and that the ignition key is in your pocket when working on the engine, i.e. if you have to remove the ECU sensor to test it or even testing the gauge sensor in situ.
