What should the thermostat be on a Chevy Blazer?

What should the thermostat be on a Chevy Blazer?

Check the heat inside the Blazer and keep an eye on the thermostat gauge on the instrument panel. Once the heat is working, the gauge is up to temp (190 degrees) and the radiator is full, shut off the Blazer and replace the radiator cap.

Where is the heater located on a Chevy Blazer?

The cabin heater in your vehicle produces heat from a heater core. The heater core is a small radiator, located under the dashboard of the vehicle and consists of conductive aluminium or brass tubing with cooling fins to increase surface area. Hot coolant passing through the heater core gives off heat before returning to the engine cooling circuit.

What should I do if my Chevy Blazer is not getting heat?

If you are not getting heat and the engine IS reaching operating temp then check the heater core by touching both heater hoses; they should both be hot. If one is hot and the other is cooler, then the core is plugged up.

How do you change the radiator on a Chevy Blazer?

When the radiator will take no more, start the engine with the radiator cap still off of the radiator. Place the drain bucket below the radiator neck, and allow the Blazer to run until operating temperature is achieved, adding more coolant to the radiator as necessary.

Where is the thermostat located on a Honda Accord?

Locate the thermostat. It is near the alternator. If you follow the upper radiator hose, it runs from the driver’s side of the radiator up across the engine, and back around over the engine to the middle of the block near the alternator.

What to do if your Chevy Blazer is hot?

Park the Blazer on the flat surface and release the hood latch. If the engine is hot or even warm, allow time for it to cool down. Open the hood and brace it on the hood prop.

Can you change the thermostat on a Chevy Blazer?

Changing out the thermostat on a Chevy Blazer with a 4.3 Vortec engine is a pretty quick and easy procedure. This repair job can be a solution for overheating as well as when the vehicle is not providing any heat. This depends on whether the thermostat is stuck open or closed.

What kind of antifreeze does a Chevy Blazer use?

Fill the radiator with 50% Dex-cool or Global antifreeze until full. This will take a while and air pockets in the radiator will occasionally burp and create room for more antifreeze. When the radiator will take no more, start the engine with the radiator cap still off of the radiator.

What happens if your car thermostat is too hot?

If a car’s engine is too hot, it can actually warp and become damaged. But, when it’s cold, it doesn’t run efficiently. So, it is important to keep the engine at the right temperature, which is where the thermostat comes in.

Why does the lower radiator hose feel warm?

The gauge will read below the regular temperature. The lower radiator hose should feel a bit warm but not as hot as the upper hose. If both upper and lower radiator hose have about the same temperature, coolant is not circulating (overheating) or the thermostat is stuck open (engine below operating temperature).

Why is my car’s coolant not reaching operating temperature?

A cold car’s coolant temperature matches the outside temperature, so I assume the sensor is doing good. First thought would be a faulty thermostat – coolant is always allowed to go through the radiator and does not let the engine reach proper temperature. So I changed it to a new one. And you know what that did? Nothing, same problem.

What to do when your engine thermostat is stuck?

When an engine is cold, the thermostat should be closed, thus bypassing the radiator. Warm (not hot!) engine test: Open hood and remove radiator cap. Start engine. Observe coolant action. It should be swirling vigorously. When an engine is warm, the thermostat is in the open position.

How do you change the thermostat on a Chevy Blazer?

Place the drain bucket beneath the radiator drain cock and open it to drain the radiator. To access the drain cock, you will have to crawl under the Blazer. Allow the radiator to drain below the thermostat level or drain the radiator completely.
