1999 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 my 1999 in 2009 for $5,500 with only 23k miles! It's been a great car for the money. I'm doing repairs myself which include servicing the window switch, plugs and wires. Serpentine belt. Had a problem with water collecting in 2 of the plug wells which turned out to be a recognized problem. The fix is to add a Barns leak pellet to the cooling system. That could be a major problem down ...
