As far as the temp gauge goes...i have a 91 1500, i had the same problem. i replaced the temp sensor and it fixed the problem.

as far as the bad gas mileage... if you haven't already done so, perform a tune up; plugs, wires etc.

I HAVE A 2004 CHEVY 1500 5.3L. THE TEMP. GUAGE PEGS OUT BUT IT IS NOT RUNNING HOT. I CHANGED THE SENDING UNIT STILL THE SAME.


You may have a bad guage. To check, ground out the sender by placing a screwdriver or alligator clips accross the ground tab and the center positive terninal. If the guage works you would normally expect a sender problem, but since you put on a new sender (assuming it's wired correctly [ no offense ]) you will need to trace t the wires from the guage to the SU. The fuel guage power lead is pink ( or at least it is on boats ) Look for a bad connection, corrosion, frayed wires or anything else that looks abnormal. You may want to simply replace the existing wire temporarily with another wire. This new wire should tell you immediately if your guage is bad. Good luck!

My temp guage is at 160. I notice my gas mileage was getting bad. what is causing this?


That could be your problem. The computer sees the temperature is low and reconfigures your fuel mixture accordingly. Replace the thermostat with a new GM unit. They are way better than the aftermarket stuff.

Trucks runs most efficient around 200 degrees.. Check air pressure in your tires air filter and you might try some fuel additive as well. Good luck!

Heaters blow cold


could be heater core failure.

If the temp guage remains cold....the thermostat is stuck open, therefore coolant is running thru the motor always. Therefore, no heat anywhere, and poor gas mileage.

Sounds like you have a ground problem, i doubt its in the sending units as both gauges are acting strange work, seeing that electricity likes paths of least resistance one gauge could be grounding through another. Bad grounds wreak havoc on electrical systems.
