Is your car overheating but your radiator seems to be holding water?

Car Thermostat Replacement

What about the thermostat?

A thermostat prevents coolant getting to the radiator until the engine warms up. Once the engine reaches its operating temperature, the thermostat heats up and the thermostat valve opens. The thermostat helps reduce engine wear and tear and excess emissions.

When do I need to replace a thermostat?

If the engine is running hotter than usual, or if the vehicle’s temperature gauge is hanging out on the low side, and the heater isn’t doing its job, it’s probably time to replace the thermostat, gasket and gasket sealant. If a visual inspection shows an open thermostat valve, the thermostat probably needs to be replaced.

What are my options?

The vehicle can either be taken to a local auto upholstery shop, or the owner can parts and perform the replacement. There are numerous automotive websites that sell parts and supplies, while others sell services, including mobile services. There are also free online DIY instructions, and service manuals can also be purchased.

The heater core is something else to look at. If it’s clogged, you won’t get heat. And if it’s leaking, it needs to be replaced right away.

My overheat situation is
coolant be pushed out to reserve, both upper/lower are HOT, lower level of coolant in rad
the ard is ‘cool’ while overheat. I do see bubbles from opened rad cap, of course air in the system BUT, should it be if coolant be burned, it can produce bubble. Knowing air in the system is no good.

sometime, everything seems working fine, upper and ard is hot while lower is not as hot, this sounded very normal and of course no over heat sign.

From time to time, if I pour coolant back to rad from reserve, system pushs them back out to the reserve again in short period of drive, I know the rad level is low for sure.

After many reading, I sort of thinging this is more of the Thermostat problem but i do like the
expert’s advise before I go ahead to replace it.

Appreciated all suggestions.
