Why does my 94 honda civic over heat but the oil light comes on there's no leaks any where?
My radiator over heats the hoes swells but there's no leaks no smoke coming from anywhere the water in the radiator bubbles up when I take the cap off I even put some stuff in it to help cool it down didn't work. I checked the oil looks fine no werid color to it at all. Its no really over heating the engine is hotter then what its suppose to be
It could be any of the following: Radiator cap, Clogged up radiator, Thermostat, water pump, cooling fan(s), head gasket, restricted cooling passages in cylinder head or engine block etc. Look at these videos to show how to check and repair:
Cooling system pressure test: To find out if external or internal coolant leak:
Engine thermostat:

- Test light on positive lead on starter relay comes on when the motorcycle is off, when bike key is turn on, test light is off? Does this mean starter relay is bad? I'm trying to diagnose my electrical problem on a honda cbr f4. The lights turned on but when I tried to start bike all power shut off and now nothing powers on.
- Why does my car over heat? I have a 2002 Honda civic ex I have had the radiator, water pump, timing chain, and thermostat replaced in it recently. However when ever I drive it over 50 mph it starts to over heat and water is spraying out of the radiator through the top were cap is at. I can drive it all day under 50 mph and it is fine so does anyone have any ideas to why my car is doing this?
- Oil Change: Honda Motor Oil Vs Generic oil, does it make a difference? I have been getting oil changes with Honda motor oil for 15 years on my 2002 civic that now has 132K miles. If I switch to a generic $10 oil change garage shop will it still be ok? I know the Honda filters are better then the cheapest generic ones but how about the actual motor oil?
- My car leaks anti leak sprayed all over hood of car and everywhere dripped on floor?
