2001 honda civic ex overheats but i have changed thermostat radiator cooling fan. Can not figure out why still overheats but not as bad as before


one of three things could be happening, the heater core could be plugged up and stopping coolant circulation

or

a coolant hose could be clogged. and not allowing any or not enough coolant through.

or

Is your water pump any good?

It really does overheat a lot when in traffic.


You need to check youe water pump, thermostat and your radiator cap and if all of that is good it sounds like a blown headgasket.

What could make my 03 civic ex overheat and cool down then overheat again while losing heat inside??? Already replaced radiator, water pump, thermostat.... motor


your heater has apparently restricted the coolant flow....hopefully a good system back flushing will cure the problem....use a flush obtained from a parts house....I would buy the hose kit for flushing as well...good luck to you

1990 Honda Civic low kms. overheated, added


I want you to take a couple of spark plugs out and examine them. If you find Anti-freeze on them then you may have a blown headgasket. A very common problem of driving a car until it overheats. I really do hope im wrong. Since it is an overhead valve engine with the cam shaft above...its a 1000.00 to 1500.00 dollar job to have it properly repaired. From here out im just going to explain why this happens...
When a car overheats - be it a faulty thermostat...low coolant...or a faulty water pump or improper coolant mixture ratio. The engine gets so hot that it actually makes the top of the engine change shape... it actually changes enough to damage the head gasket. The head gasket keeps the explosion inside the combustion chamber. Keeps the water in its coolant jacket. and keeps the oil inside its ports. When the Headgasket fails. Sometimes coolant gets into the oil (makes a milky residue form on the inside of the oil filler cap...or makes the engine oil look like chocolate milk.) or oil gets into the coolant (makes your coolant have an oil slick on top) It can also cause water to get into the combustion chamber and when the engine is running - blast the combustion back into the coolant (causes the coolant overflow to overflow or spray) or oil gets into the combustion chamber causing the plugs to get fouled (dirty). worse case...all the above happens. I hope this helps in figuring this problem out...i really do hope im wrong about a blown headgasket . As even i tremble in fear of it happening to my car. Good Luck!

Running hot


Check the Tension on the Belt. If it is not tight enough or you need a New Tensioner for the Belt, It will run hot. It is not letting the Water Pump Cool the Motor fast enough. You might also Check the Radiator. If the Radiator is Even a Little Clogged, It will overheat. Also, Check the Fan clutch, If it is not working Properly, You will overheat. Let me know what you find!

My car is over heating. i have changed the thermostat and checked for leaks.


Its most likely the radiator, Mine use to overheat and I replaced everything from the hoses to the water pump. It still would overheat. Then i did the unthinkable..LOL I replaced the radiator.
