An erratic temperature gauge on a 2004 Chevy Venture can be caused by several factors, including a faulty coolant temperature sensor, a damaged wiring harness, or a malfunctioning instrument cluster. Additionally, low coolant levels or air pockets in the cooling system can affect readings. It's advisable to check for any diagnostic trouble codes (DTCs) and inspect the related components for proper functioning. Regular maintenance and prompt attention to any cooling system issues can help prevent further problems.

If the temperature gauge in a 2000 Chevrolet Venture is running low, it could indicate a few possible issues. The thermostat might be stuck open, allowing coolant to flow continuously and preventing the engine from reaching its optimal operating temperature. Alternatively, there could be a problem with the temperature sensor or gauge itself. It's advisable to check the coolant levels and inspect the thermostat for proper function.
1990 Chevrolet Lumina temperature sender is located on the back side of the thermostat housing. The sender has a wire that goes to the temperature gauge.
Chevy sells a tank additive that removes corrosion from the sending unit that uses resitance to gage how much fuel in tank. Check your local dealer for the additive, the gage usually shows an erratic reading due to corrosion, bad fuel quality at the pumps.
Bad temperature sending unit? Bad gauge?
210 to 220 is a safe range.
