1998 Saturn SW2 Problems

A/C off for Engine Protection and Engine Reads Cold

The 1996-2001 Saturn SW2 may display the warning message "A/C off for Engine Protection" on the instrument panel. This may be accompanied by illumination of the check engine light and the temperature gauge reading cold at all times. This is a feature of the engine that is activated by the power control module when it detects the engine warming up too slowly. The OBD trouble code P0128 may also be stored. 

The cause is simply a worn out thermostat that stays open at all times, preventing the engine from reaching the proper operating temperature. 

Replacement of the thermostat will correct the issue. 

Contamination of extended life coolant
Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
Check Engine Light Due to Gas Cap Issue

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Bought it new, the only thing I ever did up to 234,000 miles was replace the starter, water pump, fuel pump, front rotors, that's it! (other than tires, plugs, wires, and front brake pads) At 234,000 miles it would smoke when coasting down hill in gear and then hitting the gas at the bottom of the hill. The car was still running great but I swapped the motor for a used one at this time. Als...
Probably the best car I've ever owned. So far, necessary repairs have been brakes, batteries, an oil pump and a radiator. Being a former SCCA driver, this car has been opened up from it's original 124hp to 145. Suspension has been reworked and I run nitrogen in the 205/60/15 tires. It's been across the country & back several times. I never worry about it breaking. Auto trans and engine get 100...
