Engine heating
hi guys ,
I just bought a Honda civic Dx 1994 having 170,000 k miles on it. 2 days back i found out that when the car is idling the temperature gauge for engine heat rises above the half way going towards hot, when i start driving again the temperature gauge returns back to below halfway mark. Also turning the A/c aggrevates the above problem. I went to the HOnda dealer mechanic, and he is saying the head gasket has a crack and needs to be fixed, he is charging 1000 dollars for it. I want to check with u guys if any of u had problem like this before. Also i dont think head gasket is cracked because it would cause the temp to rise even when i am driving. |

Re: Engine heating
Thanks for ur suggestions i will check those things u have stated, do u
think it can be really the head gasket. |

If you have good compression then the odds are *very* good that you have a good head gasket. If you have bad compression it might mean a problem with one or more of the following: head gasket valves rings I'd expect a bad head gasket to also cause one or more of the following: water in the oil oil in the water exhaust gas forcing the coolant to leak out of the coolant overflow Overheating at idle could simply be a cooling system issue: fan not working reduced radiador function (ie: bugs in radiator) |

Head gasket problems, especially those related to overheating, tend to get a lot worse when the engine is under load - that is, when driving. The higher combustion chamber pressures force more combustion gasses into the coolant. If you want to do a quick test, remove the radiator cap when the engine is cool. Start the engine, pinch closed the tube that goes to the coolant reservoir, and put the palm of your hand over the radiator cap opening. If you feel either a pulsation or a steady rise in pressure on your palm immediately, that's bad news. If not, you can bet the head gasket (or a cracked head) is not causing your overheating. My main thoughts are just the sort of things Jim mentioned - things related to either coolant flow or air flow. Mike |

Re: Engine heating
I'd suspect head gasket issues. My '93 did this too, the only way to help
alleviate it was to drive with the heat full on. Luckily mine occured when it was still fairly cold outside. check the colour of your rad fluid too. if it looks sludgy or off colour in the resevoir tank, suspect that oil is leaking through the gasket.

That is what happened with my 94 Integra(same symptoms),and a new TS fixed it. I would not go back to that mechanic. -- Jim Yanik jyanik at kua.net |

Re: Engine heating
hi,
Thanks for ur responses, i would take the car to a different mechanic and check for the thermostat and radiator. |
