I would assume that it would be your water pump. Check to see if the fluid is comming off of the water pump in the front of your motor, you should be abe to see a drip on the botom of the pully.

Temperature gauge does not work


coolant temperature on 4.0L engine. indicator reading does not match obvious temperature of the engine? and by "does not work " you mean temp gauge reading does not respond to anything? well, without any data or test info so far, i would say make sure its filled up with coolant, look for obvious leaks, remove wire from temp sender at the front of the intake manifold. turn the key to the run position,no need to start. attach a wire connected to engine ground on the battery neg. post. observe the indication. does it go up and full ? this is a simulation of full reading and beyond. basic wake up test. an educated guess at that point would be the sending unit has failed and or is not in good continuity with the intake on top of the eng. if it was full of coolant at the beginning, replace the sender with the motorcraft updated part or equiv. retest. report your findings here to tell what you find. further testing is done with a gauge simulator and thermostat modulation is read with a scan tool by most technicians to be sure the t- stat operation is in spec. service and maintenance are then recommended based on observations, tests, and reading the customers file of previous work.

I had a water leak on my 1996 GMC K1500 and ran hot. Fixed problem truck running good, but the temperature gauge is pegged high even with a new sensor. How do I fix the gauge?


Pull off the negative battery cable and unplug the sensor. See if the gauge needle returns to normal. Try tapping on the cluster to unstick the needle. No luck? Replace the temperature gauge.

Help needed to figure out why truck says it over heating


you might want to check the wires going to the temperature sensor on the engine make sure it hasnt rubbed the protective coating off, this can give you a false reading, the safest way is to put a manual gauge in place of the temperature sensor and run engine to make sure the engine is not overheating. You can pick up a cheap manual temp gauge at your local parts store and install the temperature probe into the hole where the temp sensor was located and run the engine. It sounds like you have a guage malfunction. But is better to be safe than sorry.

Did the engine overheat before the water pump was replaced? If so, you may have a warped cylinder head and/or blown head gasket.

Was the radiator full of rusty-colored liquid before you flushed it? If so, your radiator is probably restricted with rust deposits in the cooling tubes. Flushing WILL NOT get this stuff out. The radiator MUST be replaced if this is the case. Your heater core is probably not in real good shape either, so you should be expecting some heating problems this winter.

If the above is not the correct answer, then you should check to make sure the temperature gauge is not "LYING" to you. This could be caused by a defective gauge, a bad temperature sending unit, or faulty wiring.

The way to check this is with a scan tool that can read engine data and an infrared thermometer. While reading the coolant temperature data from the computer, check the cylinder head temperature with the infrared thermomometer. The readings you get should be within 5 degrees (F) of each other. If the computer data does not match the thermometer within the 5 degrees, then the sending unit for the computer should be replaced.

Then look at the gauge to see if the gauge reading is appropriate to the temperature readings that you took. Normal operating temperature is between 190 and 230 degrees. This should place the gauge at slightly to the right of center to about 5/8ths of the way to HOT. If the readings you took are OK and the gauge is reading higher than this, then you should try replacing the temperature sending unit for the gauge and see if that fixes the problem.

Please note that there are TWO temp sending units: One for the gauge and one for the computer.

temperature gauge is not reading correctly and the car is overheating due to a leak or a blockage in the coolant system.

Yes it looks like it. Provided you installed the thermostat in the correct direction, Here's the test, remove the radiator cap, start the car and wait for the engine to warm up, When you can see the temp begin to rise on the gauge the thermostat will open. While reving the engine look for turbulance in the coolant/antifreeze in the radiator opening.
If none is observed then replace the water pump.

Water leaking from behind a pully on the block. how or what can i do?


the pully that the coolant is leaking out from sounds like your water pump. with no coolant in the system the temperature gage wont read the correct temperature. replace the water pump and pray that the engine didn't overheat, as to do permanent damage.

Dash Temp Gauge reading extremely hot


You need to pressure test the cooling system. If it holds pressure, I would look at replacing the water temp. sensor. If it doesn't hold pressure, you have a coolant leak going on. If you don't see it dripping on the ground or inside the car, I would be suspecting head gasket problem.
