I have a 1995 Accord that I bought last spring. It has 160,000 miles on it and the temperature gauge is acting a little funky.
After the car has been warmed up, if I run the heater/defroster, the temp gauage will drop down to zero. Once the heater is turned off, the temp will slowly climb back to it's normal position. Also, on two occasions after a highway commute the engine RMP has "bounced" rapidly back and forth between 1800 and 900 RPM once I come to a stop and idle.
I was hoping that I just had a bad sensor or thermostat, but after popping the hood, I was a little low on coolant. This could indicate a bad head gasket, correct?
For the time being, I bought a new temp sensor and themorstat and am hoping for the cheap fix. My question is, there are 3 sensors on left side of the engine, which one is the coolant sensor that goes to the gauge? It looks like the center, lowest one under the distributor cap.
Any guesses as to the correlation between turning the heat on and the temp dropping?
I hope it's not a head gasket as I only paid $2500 for the car and am not going to put in another $1500 to have the head gasket replaced.
have the same problem?
