Q: Overheating condition of my engine.

asked by on March 03, 2017

We replaced the thermostat, intake gasket ,clamps, and water pump, the heater core was bypassed.. There are no leaks and no coolant loss. There is a faulty temperature sensor though. The upper radiator hose tends to have pressure on it. I repeat the coolant level stays the same. The temperature gauge tend to bounce around the it will say it's overheating but when I check the engine is cool to touch. It runs just fine when the lines after the lines are bled. I'm at a loss right now. No smoke and a new cap on the coolant jug.

My car has 246000 miles.
My car has an automatic transmission.
