My 1994 Pontiac Firebird formula v-8 with 157000 miles is overheating during the day when it is hot out and I am in traffic. The low coolant and check engine light is on. I check the check engine with computer and it says it has a coolant level sensor not working. Is this the cause of my car overheating? In the morning it does not overheat in 65 degree weather but in 85degree weather it does.

Determine if the fan even runs first off and then deal with the sensor. You can check the fan by connecting it straight to the battery.

Suggested Repair

Confirm whether the cooling fan runs, including by connecting it directly to the battery. Then check the fan fuses, relay, and wiring before addressing the coolant level sensor.

Conversation Summary

A 1994 Pontiac Firebird Formula with 157,000 miles overheats in hot weather while stopped in traffic, but not in cooler morning conditions. The low-coolant and check-engine lights are on, and a scan reports a coolant level sensor fault. Replies advise checking whether the fans come on when stopped, including fuses, relays, and wiring, and testing the fan by connecting it directly to the battery before dealing with the sensor.
