For about 2 months my car has been gradually losing coolant but I cannot find any leaks. It seems like I need to put more coolant in about every 500 or 600 miles. About 1 year ago my thermostat malfunctioned which caused it to overheat to the extent that it melted my plug wires. I say that because the severe heat may have caused some other damage. I can not find any leaks at all. One thing that puzzles me is after my engine heats up coolant is forced out the overflow reservoir. Also the level in the reservoir stays the same, no matter the conditions or even if the fluid level is low in the system.

Hi mrshawnlee,

The radiator cap might be faulty and is not keeping the pressure. Replace it and see if it helps.
