Engine Cooling problem
1995 Honda Prelude 4 cyl Front Wheel Drive Manual
Drat. Same problem. After driving on the highway, I pull into the garage and get bubbling sounds from the cooling system and the overflow tank is empty. I'm losing fluid somewhere. I refilled the tank this morning. Interesting tidbit. I had it 1/2 full yesterday and went into folsom, maybe 50 miles. I noticed a leak under the tank, popped the hood and had radiator fluid still on the battery housing indicating that it had overflowed.
I had the cooling system pressure tested and they only replaced the radiator cap which did not fix the problem. They could not detect any leaks when they pressure tested the system.
There is no smoke or odor of radiator fluid coming from the exhaust. I did notice that the oil darken much sooner than usual after changing it recently but I am not able to detect any fluid on the dipstick. It looks just like oil!
Any ideas? Leaky head gasket? Bad thermostat? Bad water pump?
have the same problem?
