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.

Bad theromostat 3.2 isuzu how to


The thermostat on the 2001 Isuzu Rodeo 3.2L v6 is located on the top of the engine under the upper intake manifold. In order to replace it you will have to depressurize the fuel system by running the engine with the fuel pump fuze removed until the engine dies and then carefully remove the fuel rail and injectors. Then remove the intake manifold which will give you access to the coolant nozzle fixture attached to the top of the engine. The thermostat is in the top of the engine block under the nozzle fixture. Be sure to replace the thermostat with the proper replacement part (may be difficult to find) and put on new gaskets for the intake manifold before replacing it.

Car over heats


Check and see if the Radiator cooling fan is working. It should cycle more or run continuously when the AC is on. There are often 2 heat sensors for the Temperature, 1 is for the gauge and the other is for the Radiator fan.

Just having water flow is not enough to cool the engine, the electric Radiator fan makes a big difference. There should be a Relay in the Powerbox. You can get Diagrams for the wiring at Autozone.com when you register for FREE. Then you will be able to tell what is in the Powerbox and get chassis wiring diagrams.

Since you had a new radiator installed, there is a possibility that the electric fan was not reconnected.

Coolant


Low coolant through the heater core. Yes it could be the theromostat.

Car over heating but no water coming from the vehicle, 2000 montero sport


there could be several reasons for this.#1 the theromostat is stuck closed.(the quickest way to check this is to get the engine to operating tempature, if the upper radiator hos is cold your thermostat is not open and needs replacing.#2your cooling fans are not operating.( you should have 12 volts going to the cooling fans and you have fuses/relays that allow this. they are located in the junction box located under the hood to check the relay just have the engine at operating temp and then switch the relay( i use the a/c clutch relay to swap with) if the fan kicks on then you know it was the relay/fuse. If it doesn't it could be the fan is bad ot the temp sensor on the fan is defective.#3poor circulation ofcoolant.(the water pump has to circulate properly in order to to keep the engine cooled down. If all the other componants check out then i suspect that the water pump needs replacement. You will also have to power wash the radiator. Bugs,dirt and road grime restrict the flow of air over the coils and fins of the radiator thus not allowing the the heat to be dispersed properly. please rate the solution......thanks
