Question about 1992 Honda Accord

1992 Honda Accord LX Thermostat Gauge Goes Directly to the "H"

So here is my headache. One day I stupidly decided to spray my engine with engine cleaner and I think that this might have caused a short circuit or something. I'm not sure if this might have caused my problem as it happened 1 day after cleaning my engine. The Gauge in my car would shoot straight up to the "H" indicating my engine is overheating, this would happen even when I turn the key to just the "On" position. I'll test it in the morning when it's cold, same thing. The engine is cool to the touch even after letting the car idle for several minutes. I have replaced the thermostat and the temperature coolant plug thing that is connected to a green connector. I have flushed the coolant. But my gauge still shoots straight up to the "H". A co-worker of mine said I might need a new switch? I'm not sure. Today, the gauge meter rose to about 75% of the way to "H" and then later 25% and then again right back to "H". Please someone help me.

    Clean the temp sending unit? Do you mean the green connector that connects to the temperature plug? Sorry, I don't know much about cars, you'll have to elaborate some more. Thanks.

Double check and make sure you have enough coolant in your system. Additionally why you are at it put in a new thermostat preferably the lowest temp allowable by manufactorer. A cool running engine is an efficent engine

Where on my 1992 Honda accord LX standard transmission is the speed sensor located?


Under your thermostat housing but on the transmission. Two 10mm bolts hold it on and there is a plug on it. If you don't know where the therm housing is, follow the lower radiator hose from the the bottom of your radiator to where it goes into the engine.

Where & how to install thermostat in honda accord ex 1992


you need to follow the upper hose that lead from the radiator to the engine, there is two bolt that connect the thermostat housing to the block loosen the bolt using a 10 mm socket with ra-chet. Make sure that the engine is cool off before attempt to do this you will lose coolant but that's ok you will add the coolant when you finish replacing the thermostat. start the engine with the radiator cap off then add coolant slowly and cap it, then fill the reservoir up.

note the way you remove the thermostat that's the same way you will put the new one so pay attention when you remove the old one good luck.
