Here's what happened today. I drove the car for around 2 hours in 95-97 degrees weather today with the A/C on. With only 2 blocks before I got home, I heard my drive belt squealing faintly but didn't think much of anything about it. When I pulled into the drive way and got out of the car, i smelled coolant and immediately looked under the car and saw coolant dripping. I opened the hood and there were coolant everywhere around the thermostat & timing belt side of the engine block. Since it's still hot, I went inside the house and wait for the car to cool down (Aprox 1 1/2 hours) After waiting for the car to cool down, I start it back up & left the engine running while: - Check coolant level - Good. - Checking all of the hoses for sign of damage/tear/leaks. None. - Check for leaks around the thermostat housing & hose. None - Check for sign of leaks on the upper & lower radiator hose. None. So the car stop leaking coolant and I thought *thank god*.....But when I went to shut the engine off, I saw the coolant meter was near the overheat mark. I think I've narrowed it down to: A) Thermostat housing/seal or thermostat failure? B) Waterpump and/or waterpump seal? The car is a 2000 Neon with only 65k miles.... anyone have any suggestion? I really hope it's a thermostat because I can replace it myself and save $.
