Honda Car Forum

3 weeks ago, i was using AC and idle my temp gauge for my engine was increasing so I turned my heater on instead. The temperature went down. My car was just fine after. Then couple of days ago my car started overheating when on stop and go traffic and when i go at higher speeds on freeways. Then it was fine again. then 2 days ago my car overheats, my bf check that the bottom hose was just cold, while the other hose from my radiator to the engine was hot. It was fine the next day after i pour coolant in. Then yesterday, I test drove. The car started overheating again. The next day the car was just running fine. top and bottom hoses were hot. The fan was working. The last time I took it to a shop the guy said my oil is seeping. What could be the diagnosis of this "sometimes overheating of my civic 97?So yesterday my bf tried the thermostat on a boling water. It worked, but he bought and re-installed a new one anyways. I took it for a drive and it was fine, so he poured water around the engine and thermostat below to find out if it was leaking. And it was, a skinny hose at the bottom was leaking coolant. We could see green coolant coming out.Today is test drive day, to find if it's fix.

your thermostat is not opening ,. replace the thermostat

the thermomemetre needs replaced

Man....a Honda -- surprised -- I had a FORD (FOUND ON ROAD DEAD) car......so that was my guess. Now that I know it's a Honda, it may not be as bad as it sounds -- they are good cars from what I understand. May not be too expensive to fix....

yeah you need a new thermostat, it isnt opening to allow water to flow and cool the engine.

thermostate bad? electric fan/sensers going bad..if car is all right on the move ,that fan is bad

usually the intake or the head gasket!

Have someone check your water pump, replace your thermostat, and maybe even run some coolant system cleaner through your radiator, Have someone who knows what they are doing do these checks.

There are a couple of things to consider. If the bottom hose was cold it gives the impression that the radiator is plugged. The oil seeping tells me to look for possible head gasket trouble. Honda cars are known for people overlooking the air pocket. There is a air valve on the water system that needs to be purged. If you ran the car low on fluid and just put fluid in and did not purge the system there could be air trapped, causing it to overheat. There are some other things but I am assuming no one has played with the wiring.

The thermostat is not opening. Replace it.
