Is my cluster bad? Fuel gauge and temperature gauge are not working?

The fuel gauge and temperature gauge are not working; needles are below zero. Will it correct the problem if I change the cluster assembly and will it worth replacing it? Thanks so much.

Just bought van with knowledge of the thermostat needing replaced. Bought from the 2nd owner since 80,000 miles. Now has 253700. My issues are is that I replaced thermostat drove fine with barely hot heat for about 300 miles. Now temp gauge jumps hot to cold, also have had it flushed and a new coolant sensor. Drove fine for 50-60 miles and now temp gauge is either extremly high or really low. Mild warm heat, drives awesome still. Getting frustrated.

Would that cause my temp gauge to bounce around? Im not losing any antifreeze as in intake or a head gasket problem. Would a water pump have any effects?

Thanks I am replacing thermostat again tomorrow and continue to bleed the system aswell as checking into getting radiator cleaned

O replaced thermostat and have heat in front but not back is there a bleeder valve for the back heat system

Temperature gauge on dash always reads cold never moves. Tested thermostat thermostat is good replaced temp sender. Flushed coolant system. Still no reading. What do I do from here? Thank you.

Still giving me same problem would intake gasket do it?

All gauges respond except temp. Also read about a ground test (touch green wire contact on temp sensor connector to ground key on engine off) and gauge did not respond.

Engine Cooling problem
1999 Chevy Venture 6 cyl Front Wheel Drive Automatic

changed thermostat, bled both bleeder screws. Changed low coolant sensor, changed water pump and the coolant gauge still rises then normal, rises to red, then normal, then low coolant light on, then off, level goes back up then down. Any idea whats the problem?

My van has a cooling system problem. During Idle, after my van gets up to operating temperature, my temp. Guage fluxuates between 3/4 to red hot with the warning light. Seems to only happen while @ idle. The temp. Guage goes down to almost normal but slightly fluctuates while driving at normal speed. The fans are working and it is full of antifreeze. Not sure how to bleed the air out of the system. Replaced the thermostat before winter and it had heat. The A/C however has not worked since we bought the van a couple years ago. Not sure what I need to do next. Help?

My first thought would be that there is air in the cooling system. If this van has the 3400 V6 engine it, there is going to be a bleed valve on the upper radiator hose housing, the second one is on the passenger side of the vehicle. Its on a tube that runs around the motor. Its going to be a black metal line. You want to crack the lower one first and bleed the air out. You want only a steady stream of antifreeze. Once the air is bled out of that one, crack the one higher up. Make sure there is a steady stream there also, refill radiator and overflow tank. While running and the cap is off of the radiator, check to make sure that the antifreeze is coming back out the top, the only concern I have is with it being a 3400 V6, the odds of it needing head gaskets are likely. Hope this helps you out some, let me know if there is anything else.

The van is a 3.1 liter. What is the procedure to bleed the air out of that size engine?

The 3.1 or 3100 vs. 3.4 or 3400 are virtually the same, the bleed out procedure should be the same. Except on the 3100 the bleeder is on the passenger side, on the top of the motor. It is on a a black metal tube, next to the power steering pump. Check to make sure coolant is full, and start the vehicle. Once it gets up to normal operating temperatures, crack that bleeder open slowly. You should have a small amount of coolant coming from bleeder. Let it bleed a few seconds then close it, and wait a couple minutes. Then crack it again and repeat this process until there is no more air in the system.
