92 Accord Running HOT? Also sometimes IDLE BOUNCE... Thermostat??
Hi
I have a 92 accord, 285,000 KM on it. Just yesterday I noticed the smell of anti-freeze... soon later after driving and coming to a stop I seen anti-freeze steam rising from the hood.. I also noticed that when the car sits at idle the temp needle rises above the H line.... but as soon as I drive it goes back to normal. Today I started my car and after about 5 minutes once warmed up (its like -10 here now) the idle was bouncing from 800-2000 over and over.... once I put in drive it went back to normal. The temp needle was also rising above the H line... I started driving and everything seems fine but the needle seems to lower and rise above the H line.... after 20 minutes or so I came home and just let the car idle, there was no longer an idle jump from 800-2000..... Im confused.... could this be a temperature coolant sensor? or could it be my thermostat? any help would be greatly appreciated! -one other thing... since i bought the car this summer when I shut the car off sometimes the fan kicks in. |

You'll see the level has dropped as the engine purges some air from the system and 'sips' it from the reservoir. Owner's manuals are often available from wrecking yards for about 1/3rd of the dealer price. 'Curly' |

I would check or replace the thermostat. sounds like it might be stuck closed so hot coolant is only circulating in the engine bypassing the radiator. |

92 Accord Running HOT? Also sometimes IDLE BOUNCE... Thermostat??
Today I drove it around looking for a thermostat at some auto part
stores around here... not one place has a thermostat for my car... but anyways, while driving... after maybe an hour of stop and go... the check engine light came on, and the car started to lose power... the temp was also above the H line.... one more thing is I lost the heat in my car today.... Im starting to think this is a coolant temp sensor, and maybe a thermostat too because of the sudden heat loss.... What are your thoughts? |

I would also like to add that for about 20 minutes the cars idle was
jumping from 1000-2200 rpm. Its done that yesterday and today once the car got warm. |

Cover LOWER port in the throttle body with your finger. Does bouncing stop? Then Fast Idle Thermo Valve is stuck open. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

Don't use an aftermarket thermostat. That's asking for even more trouble. Use a dealer thermostat only.

Should probably be replaced every few years as a matter of PM. |

Not a good thing. > Should probably be replaced every few years as a matter of PM. 100% correct. A bad rad cap can sometimes be misdiagnosed as a blown head gasket. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |
