How do you replace a thermostat 1998 Chevy Malibu 4 cylinder?

Answer 1

Should be located in a removable housing at the engine end of the upper radiator hose

Drain about 1 gallon of coolant from the radiator

Remove this housing

Make note how thermostat is installed

Clean both surfaces

Install new thermostat and replace housing

Re-fill coolant slowly to prevent an air lock

Start engine and look for leaks

Run engine to normal operating temperature with heater on

Re-check coolant level

This is incorrect it is not there do not mess with that part unless you want to pay for more gaskets for no reason !

The chevy malibu 2.4l 4 cylinder is different it is located ant the end of the lower radiator hose, follow it down till you see bolts not a clamp it is attacked to a metal piece and goes up and is a lot harder to mess with i know this because i am doing this same exact thing myself.

What you need to do:

Get one the of more high dollar thermostat with fail safe stick this thermostat is the best of the best unlike other thermostats if it fails it locks open instead of closed saving your block from going out and bubbling out of over flow tank !
