The thermostat is in the water pump on these motors(front middle of motor). Follow the radiator hose. There are two bolts to remove then the thermostat pulls out.

Why is my heat or air is not blowing and car is running hot


How hot is the engine running in degrees f? Does the radiator fan run?
With hvac turned on, check voltage and ground at the blower motor. If good voltage and ground, suspect the blower motor is faulty.

sounds like you have a coolant leak, if coolant is low it will cause both of your symtoms as to where it is coming from, there are many places but common ones are hoses/clamps, water pump or radiator.

Well had the same issue on my duel climate controll 04 2500HD but changing the heater control solved the different temp.The only other thing would be your mixer door motor.There are two,one for DR side is probibly stuck..As far as the blower motor.The resister should have taken care of that.Sounds like you may have another bad one.May want to take a volt meter to the resister plug in and run you different fan speed just to make sure that you get voltage to the different conecters.

1999 pontiac sunfire over heats vents blowing cold air


Take the inlet & outlet hose off of the lines feeding your heater coil, where it come off the motor. Do you have good pressure on your water supply to your house????? If Yes. Flush the water thru the heater hose backwards from the diterction that the water normly flows from your car motor. Alot ot the time your heater core will just be plugged up and need to be backflushed. Also make sure that you do not have trash/ leaves in your heater box?????
You can also later on after flushing the H-core out, you can flush your motor, radiator & heater coil by dropping everything out and add water plus 1-can of old style Comett. This is very abrassive!!!! Run the motor for about 1-hour. Then drop all of it out. Put just water back into the system and run again about 10-minutes.Do this flushing about 3-times. You will see how clean your radiator will be, plus the cooler your motor will run.

05 silverado running hot


Hi!
Look like you may have an air lock.
Put the car on level ground, start it from cold with the coolant filler cap off, have plenty of warm/hot water available.
Leave to idle watch the coolant filler area but NOT TOO CLOSE, when at operating temp it may appear to boil over loads of bubbles, gurgling and some steam, top the coolant system up with the warm water wait until things settle then replace cap you may have to do this a couple of times.
Remember your anti freeze?
Good luck!
