Why is my 2002 honda civic overheating

A good independent mechanic should be able to correct your problem very easily. Is the electric fan on when it overheats? If not, do they at least turn on when you turn the AC on? Is there a bleed screw near the thermostat housing? Open it until only coolant without bubbles comes out.

This is not new. My Ford Galaxies Had a small pressure tank under the radiator cap that was then connected to the radiator. I had this same problem last year with my Honda, only had overheating issues in stop and go traffic. After replacing the thermostat and the radiator, we found that the real problem was a blown fuse on the cooling fans…really easy fix but after we dumped money into replacing the other two first.

Since that fix, there have been no overheating problems for a year. There is a bleed valve next to the thermostat housing. It looks like a bolt with a chimney on it. Any ideas on what the problem might be? Also, the resevoir stayed full, until the last time it overheated, and not it's really low. Any help or ideas would be greatly appreciated. Do you. Try replacing the thermostat, if it continues get it block and pressure tested- Was this answer. Hi nilocj13, Save on the thermostat replacement, get it block and pressure tested.

The head gasket is most probably blown. Did you have any overheating experience in the past few months? Also, the smoke will feel extremely humid when coming out of the exhaust pipe. All these symptoms point to one component — the head gasket. Also, a compression test to the cylinders can lead you to the head gasket issue.

If you find the pressure in one cylinder is lower than the rest, it must be a bad head gasket that causes Honda Civic overheating by either pumping compression into the cooling system or burning the water in the engine. If you use a sealant in the coolant system, it will likely to have brown gunk that can smudge the thermostat. A sticking thermostat causes boiling the antifreeze and pushes it through the radiator cap, causing the engine to overheat.

An overheated thermostat is damaged, so it requires replacement. No matter what the source of the problem is, an overheated engine means the thermostat is already out of order. Driving Tips. Maintenance Tips. Car Review. Car Comparison. Industry knowledge.
