Engine Cooling problem
2005 Honda Civic 4 cyl Front Wheel Drive Automatic 75,000 miles
The coolant is overflowing and spraying from the two small holes under the coolant reservoir cap - only during extended highway driving. I am unable to create the leak with routine short trips, extended periods of idle, etc. Once the car is parked and allowed to cool overnight, the reservoir level never quite returns to "max" - it remains elevated instead of being pulled back into the radiator. The car hasn't overheated, and the needle never rises above the halfway point. Could this be air in the system. Is there anything that would prevent return of coolant to the radiator after the engine cools. I replaced the radiator cap first - no change. I rented a leak tester and combined that with UV dye and was unable to create leaks anywhere. No oil/coolant contamination visible. No performance problems. No overheat. Any suggestions or advice would be greatly appreciated.
have the same problem?
