The heat is generated by the lamp whether or not there is an input signal. If the unit seems to be hotter than normal, check the air input grill and be sure that it is celar of dust and debris. You can also gain access to the fan and be sue that the fan is clean.

Temp/gauge not reaching normal working temp-richer


the first thing to check is to feel if the radiator is hot, if the radiator feels hot and the engine is also hot the coolant is circulating ok then the problem is more than likely electrical, the temp gauge gets its signal from the engine control module the coolant temp sensor sends coolant temp signal to engine control module for engine managment purposes then passes it to instument pack/gauge, if the sensor was at fault you would have engine running problems also,with poss fault codes logged, if the engine and rad are cold/only warm after the engine has been run for 15 mins or so it sounds like the thermostat is stuck open but you have changed that. i have had faulty new ones in the past and have had to test them in a pan of boiling water, hope this is some help to you.

Why did my enginee hot a/c off light come on and my enginee wasnt running hot


Most cars have a temp sender which is what supplies the reading on your dash, and a sensor which supplies a signal to the computer. The dash senders are typically not very sensitive so they tend to read a lot more in the middle when the coolant may be getting too hot (but not dangerously so). If this continues when the engine is cool from a fresh start then one of the two is likely faulty.

Where is fan #1 temp. sensor located.


Dang, you are correct to assume what you have. 3 prongs does the PCM and the IP. Older ones have two sensors, one for the PCM and one for the IP. So if you're running hot, First guess would be the coolant sensor. But you would need a scanner to confirm this.

2007 Chevy Silverado 2500 HD. I was driving and my digital dashboard reported engine hot and AC turned off. My temperature gauge read cool. What do I need to replace?


This sounds like a bad coolant temp sensor that give computer false reading, check the coolant temp sensor connector and if it is good with no bad wires to connector then replace coolant temp sensor , when the computer gets a signal from temp sensor that engine is hot it turns fans on high speed to cool radiator and displays a/c turned off , if this truck does not have electric cooling fans then they wont run just explaining what happens depending on engine and cooling set up. replace coolant temp sensor and check connector.

My temp gauge is not working and since that,when the car is hot,it stops everywhere and it is hard to start,like it s flooded ( to much gas )is it the temp gauge the problem!


Hello francis.

If the temperature sensor is defective it will send a cold signal to the computer.
This cold signal will make the engine run rich (too much fuel).
Cold engines need more fuel to run so that is why it is rich when hot.
But...the computer has a separate sensor from the gauge sender.
Which engine is in your Pontiac? 2.2 or 2.4 ?
Let me know here and I will send you some location diagrams.

93 villager runs good, but temp. gauge runs up to the hot line, but never runs hot. is the a colling fan that should go on.


the cooling fan should come on low speed and then high speed as it gets hotter.

The fan should come on anytime the a/c clutch engages, even cold engine.

Tempeture guage not working and heater is blowing out very little hot air on my ford galaxy


you need to get the thermostat changed. The thermostat controls how much coolant runs around the engine and sends signals to your temp gauge to indicate how hot the engine is.
if the thermostat is faulty it wont sent signals to the temp gauge and wont open up to allow coolant to run around the system. Your heating is run by coolant, behind the dash there is the heater matrix hot coolant runs into the matrix which gets blown inside the cab.
Fitting a new thermostat will fix all the heating and gauge problems. if your technical minded you can buy a thermostat from an autofactor (or ford, but they are expensive from ford). a garage will charge about £30-£100 ish for a new one.

hope this helps :-)

Cooling fans on 1994 Caprice classic with 4.3 v8 not coming on. I have replaced the temp sensor on the water pump, temp sensor on the block, all relays, fuses are good, replaced the ecm (engine control...


On a vehicle this age, it is likely that the fans themselves have worn out. Test the fans by running battery power directly to the positive contact. If they start, they are OK. On 4.3 motors, there is also a seperate temp sensor to signal the fans, usually called a fan switch. I believe it operates independent of the ECM. Another possible culprit is a bad ground at the fans or even a loose or corroded negative battery cable.

Driving down the road the temperture gauge pegs out hot and the engine starts to run rough and finally cuts off. Pull the battery cable to reset the electricals and everything is back to normal.


likely the coolant temp sensor. Some of those newish fords have a engine protection system that shuts down cylinders, then full shutdown if the computer gets a signal that the engine is getting hot.
Good luck!

The fan wont turn on when car gets hot


Overheating or just hot? Your temp sender sends signal to the computer that sends a signal to the fan relay that turns the fan on. You can hotwire the fan motor to the battery to see if it runs. if not that's the problem. Otherwise follow through by checking sensor and relay.
