Not exactly.
The check gauge warning light is on because the temp gauge is reading hot.
Does the temp gauge read hot as soon as you turn the key switch on, or not until the engine as run for a few minutes ?
If it reads hot without the engine being started, there may be a short in the wiring or the sensor may have failed.

Remove the Positive Battery Terminal, leave the Negative Terminal connected.  Wait 30 minutes.  Attach the Positive Terminal.  Verify temperature settings is around 70 degrees.  This procedure has been known to resolve computer settings.

there is one fuse for all the dash gauges, so chances are you have a wiring problem to the gauge sender on the engine or the gauge is defective, which is rare.

Check your ECM fuse. There should be 2 fuses for your ECM. It's the ECM that controls the function of the fuel pump. Good luck friend and it's also common for the wire harness from the frame to the fuel pump to go bad due to corrosion from the bad weather we get in the winter and rainy spring and fall.

SOURCE: how do i replace my water pump on a gmc yukon xl

First you will need to remove your tension belt from all your pullies. This is usually done finding a pully that provides tension to and takes away from the belt. HINT: It will be one that doesnt have abunch of mechanical part atached behind it. After removing hte belt in the center of the motor about mid ways up there is a pully that has a hose runing behind it. The other end of the hose goes to the radiator. Well where this plugs into the motor is the waterpump. you more than likely will need to remove the pully from the pump. afd88a0.jpgAbove is a picture of your pump with the pulley removed. The four bolts in the center are how you disconnect the pulley and the four on the side of the pump are how you disconnect from the motor. Make sure when you get done and all back together to look around the new pump for leaks.

Change the coolant sending unit for the gauge. Usually this is different than the Coolant Temp. Sensor which is for the pcm. Maybe the sending unit is no longer functioning correctly after overheating. Of course, a scanner could show the temperature as recorded by the CTS, or you could use a hand held infrared temperature device to get a better idea of the true temperature.

1999 GMC Yukon. Rear AC cooling great. Font AC not cooling as well. Replaced orfice syphon tube, vaccumed down and recharged with 2lbs R134a. Checked front temp controller. All checks ok. Front AC still...


If the rear is working well and front is not I would suspect a blend door or actuator issue in the front.Double check and see if you can hear anything moving when you are adjusting temperature from hot to cold.Also check and make sure the air flow moves properly from defrost to vents and floor etc.

My truck is not warming up as fast when the heater is on and it takes a while for my temp. gauge to move


Time to replace the Thermostat and Radiator Cap, if the cooling system has not been serviced, you may want to replace the coolant with a 50/50 mix water/antifreeze. Make sure it's 50/50, to much antifreeze will gel up and to much water will freeze or boil over. If your not sure how to mix the antifreeze, you can buy the pre mixed.

Temp gauge went to 260 & stayed there. What could be the problem?


The only real way to answer your questions is for you to open the hood and look it over. Once it has cooled down, re-fill the cooling system (use water...it's cheaper and to do repair you will need to repalce it anyhow...Once full carefully look everything over to find where the leak is.Also make sure that the drivebelt is there. (from what you said, likely it is) If it's water pump, you will see coolant running out from under the pulley. Once you have looked everything over, if you have not found leak, start engine and close the cap...look again...as pressure builds, small leaks will become more obvious. If you don't find leak, remove the thermostat and change it.
After changing stat, if problem persists, it's likely that you have either a plugged radiator or an internal engine gasket problem. If you have any auxiliary electric cooling fans, make sure they are working and also check the fan clutch on the mechanical fan (it should not excessively freewheel when hot). Whole testing, any time you replace the radiator cap you must allow engine to cool down before removing it again. Watch temp gauge while testing...don't allow engine to overheat.

99 yukon temp gauge never warms up past 150-160. runs cold


First test your coolant with a thermometer when it gets to full hot. Don't get scalded with the hot fluid.
if it is hot enough maybe the water temperature sensor is faulty. If the sensor is good then try putting the thermostat in a pot of water and with a thermometer test when it opens. sometimes even a new one is not accurate.
To test your rear window defroster,check your fuse, if good follow the circuit with a voltmeter. Wireing diagrams are in the Haynes manual.
