A 1989 Chevy Cavalier will not stay running after it has started if the spark plugs are fouled, the fuel filter is dirty, or it has a vacuum leak. Taking the vehicle to a local mechanic or dealership can pinpoint the problem.
It is right behind the right headlight under the battery box attached to the inner fender.
Most came with 195 F. thermostat.
