My 2005 Honda Civic is overheating. I have oil leaking into my coolant. What is causing the problem?
My 2005 Honda Civic is overheating. I have oil leaking into my coolant. What is causing the problem? I had a pressure test conduct and it was okay. I replaced my thermostat and waterpump. I coolant fans was checked and okay. I was also told by two seperate honda dealer that my engine head was not cracked or blown head gasket. Also, after running for a couple of hours, my coolant bottle overfill and that when the temperature gauge go to red. Once I siphon the coolant out of the reservoir bottle and placed the fluid back into the radiator, the car will run fine for another 2 to 3 hours of continues running. I am loosing oil and the reason I know oil is leaking into my coolant is because of the oil residue left in the coolant bottle. Help!!

You have a circulation problem. The air gets cold because the coolant is not circulating through the heater core, and it overheats because the coolant is not circulating through the radiator. I would suspect you either have in internal problem with your water pump, or a blockage somewhere in the system. It stays cool when you are moving because the air is blowing across the motor, and the waterpump in moving at a higher RPM when the motor is at a higher RPM. A stuck thermostat could cause issues like this as well. I would replace the thermostat, and completely powerflush the cooling system. If that does not work, I would geive a close look at the waterpump. I have seen damaged impellers cause poor circulation.

Head gass cate is just leaking when the engine is hot.
Or you have hole in the block that is leaking when the engine is hot.
Check all hoses and flush the radiater, air bubles in the cooling system can cause the engine to over heat to the point of leakage.

you have a blown head gasket.repair it or do more damage to the engine,if its even still running.if you run it too hot like that you will run the risk of warping the head.
