1999 Saturn SC2 Problems

A/C off for Engine Protection and Engine Reads Cold

Owners may notice the warning message "A/C off for Engine Protection" displayed on their instrument panel, 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. 

Transmission Fluid Leak From Cooler Line

An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.

Check Engine Light Due to Gas Cap Issue

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

My wife bought the car new. Now has 71K miles. No need to change the oil, just the filter. It needs one quart of oil every 1000 miles. Loud engine, shakes very bad. Horn will sound for no reason then burn out (on my third horn). Automatic shifting is terribble, 3 sec hesitation when engine is cold. No heat in the winter. Need to fill tires up with air every three weeks, factor rims suck...
