Replace the coolant, thermostat, turn off the A/c, in emergencies drive with the heater on, increase the air flow through the radiator, have your radiator checked for blockage.
temp light is on a 1991 Chevy lumina car not hot...
Could be low on coolant.
system running hot fans not running
There could be a number of reasons why a 2000 Chevy Lumina's transmission would make a bump after the car has been driven a while, and it is hot. The bumping is caused by a failing transmission, and a mechanic will need to see it.
thermostst may be sticking
The temperature light comes on in a 1992 Chevy Lumina when the temperature of the engine reaches the boiling point. The light may also come on if the transmission gets too hot. Usually a leak in the radiator system will cause a loss of fluid and lead to the temperature light, but it could be anything and must be checked.
In a Chevy Lumina, low coolant means that the car needs more anti-freeze/coolant added. This is needed to keep the engine from getting too hot
possibly the water pump
Hi,I have a lumina 95 which just recently had an air pocket after changing a radiator hose.I was told by a friend who is a mecanic to run the heater on high (hot air)which i did while on a trip and it seems to have worked.
probally wired the pump wrong
Vehicle running hot? and fan trying to cool it down Bad temperature sensor?
it was the fuse. it is in the glove box it is maked (cluster) 10 amp fuse fixed it all.
