Early and mid 2000 GM Trucks have a instrument cluster issue, think the cluster is your problem and the unit will have to be repaired or replaced.

SOURCE: temp gauge and gas gauge not working

I had the same problem with my 2001 Pontiac Montana and the intake manifold gasket. This is a major problem with these 3.4L engines, if you are in the states I'm pretty sure there is a class action law suite against GM for this. I had my manifold gasket replaced and it was about $1000 CAD. You need to get your vehicle looked at right away as this could cause major engine damage, coolant will leak into the engine and soon enough you will be replacing that too. Good Luck

Gm has a real problem with fuel tank sending units. That is what is wrong. You need a fuel tank sending unit. You can only get them aftermarket with the whole fuel pump module, but you can buy them seperate if you buy it from the dealer.

Fairly common problem with GM vehicles. The sending unit in your tank has a small circuit board that an arm is attached to which moves up and down according to your fuel level. This circuit board and arm are not making good contact. Unfortunately the only good solution is to replace this part.

Hi:
Your tank sending unit is bad. Unfortunately, it is part of the fuel pump assembly, and the part costs around $400, give or take. plus installation labor. It is an all too common problem on GM vehicles, as I have had to change it on my last 2 GMs. If you do an internet search you will find plenty of others in the same boat!

SOURCE: Fuel gauge/temp gauge not working

There are two sensors, one for ECU temp. readings with two pin connector and other one with only one wire, which has been probably disconnected when you replaced the CPC solenoid - very close position.

If you have a viscous fan hub then have it replaced as it is not drawing air through the radiator at idle or slow speed (crawling traffic). Check that are no air locks in the system as they will cause heating problems.

2001 Chevy Venture - My heat is not as hot as usual and blows cool when idle. Coolant level is fine. Temp Gauge isn't working.


Sounds like you need to have the cooling system flushed out then have them put a new themostat in it. If that dont fix the prob you might have to put a new heater core in it or radiator.

1996_gmc_sierra Heat gauge started going from 260 degrees back to normal. I replaced heat sensor then thermostat. This summer had complete radiator and cap put in. The gauge says its running at 230 an


My Mountaineer had a similar problem. When driving it, the temp needle would slowly go up and up for like 3 minutes then it would come down within about 30 seconds. Then it would slowly rise again. just kept doing this over and over but it never went too high. My gauge didn't have numbers on it but it would go up about half way (not near the too hot level though) then fall back down to about a quarter of the way on the gauge. Found out that the fan clutch was bad on my radiator fan. It was not engaging and disengaging at the right times. New fan clutch solved the problem and probably saved the engine from overheating eventually if it had gotten even worse.

Ive been having issues with my temp gauge sometimes it will move but it will just drop back down randomly and go back up again and sometimes it wont do anything but its never just worked properly sitting...


Its fine, temp needle going up shows that engine is warming up and as soon as the radiator fan starts, temp of coolant drop and this is shown by the temp gauge needle. In most cars (even mine) it stays in middle most of the time unless you are in a traffic with AC on, it will show up more temp. What you can do is get the radiator flushed and coolant changed. Also check the water pump. To do so when engine is cold (in first start in morning), open the radiator cap and ask someone to rev the engine. If the coolant level moves up and down then water pump is also fine.

Tunatic, Personally I would agree to check for a short to ground in the circuit. However, verify the sending unit first, it cost less than $20 and can be replace easily.
Good luck and let me know if you need anymore assistance.
