Need to replace the heat sending unit on 1991 buick regal but cannot find where the part is located can you please advise me of where the heat sending unit is


If you mean the engine temperature sending unit, it should be on the cylinder head and has a single wire attached to it. It looks a little like a miniature spark plug with a black insulation. To simplify your search, buy the new one and look for the same thing on the engine.

Where is the temperature sending unit located on a 2000 chevy s10 2.2 four cylinder engine


The temperature sending unit is screwed into cylinder head. Careful you also have a coolant temperature sensor that threads into intake manifold. Temp sending unit is how your guage knows how hot your engine is. Coolant temp sensor is how your computer knows how hot or cold your engine is, so it can compensate fuel & air mixture.You can not put the wrong one in the wrong place, they will not fit. You change 1 for 1 reason & the other for another reason.

The temperature sending unit should be located on the drivers side cylinder head between the number one and the number three spark plugs, that is if it is the original engine.

Fuel guage & water guage are not working properly the fuel guage reads ful then will go to empty after you drive it for awile - the water guage only goes up to a quater


The gas tank sending unit has a float on it to register the amount of gas in the tank. The float is probably faulty which will cause erratic readings and is a fairly common issue with some GM units. Replacement of the sending unit should resolve that issue. As far as the coolant temperature gauge, it could be a faulty temperature sending unit or a thermostat that is stuck open or someone removed the thermostat. This will cause the engine to never reach operating temperature which in turn makes the engine run rich and can clog cat. converters and destroy some sensors.

Changed thermostat doing the same thing, blows cold air


Allow the engine to cool down before attempting this replacement. This would minimize loss of coolant.

1. You need to replace the temperature-sending unit, also.
2. Use a 17-mm deep socket and wrench to unscrew the temperature-sending unit. It is located to the right of the thermostat housing with electrical wire plug.
3. Reverse this proceedure for installation.

This is most likely caused by a faulty temperature sending unit. It is located under the hood, driver's side upper engine area, end of cylinder head and mounted below valve cover. Hope this helped and best wishes.
