How to Change a Turbocharger in a 93 Saab

Saab began equipping its regular production cars with turbochargers as early as the 1960s. In 1989 General Motors purchased Saab as a counter to the acquisition of Volvo by Ford Motor Company. For the 1993 production year, all Saab models were GM platforms, and the turbochargers in the their engines were as reliable as most other brands. However, in a vehicle this old, the unit might need replacing due a number of factors.

Instructions

1

Park the vehicle in an area away from traffic and engage the emergency brake. Open the hood and disconnect the cable from the negative terminal of the battery.

2

Place drop cloths over the front fenders to protect them from scratches. Remove the engine cover from the top of the engine by hand. The turbocharger is located between the air inlet pipe and the engine. Unplug the air mass sensor from the side of the turbocharger, it unplugs by hand. Unscrew the O-ring clamp from the air inlet pipe and then pull the pipe off the turbocharger intake. Unbolt the three bolts on the down pipe from the rear of the turbocharger

3

Unbolt the two bolts that secure the turbocharger to the exhaust manifold. Then unbolt the single bolt on the steady arm on the side of the turbocharger. Remove the turbocharger and place it to the side. Slide in the new turbocharger and install the exhaust manifold bolts. Then install the steady arm and the down pipe and attach with bolts. Plug in the air mass sensor and screw the O-ring onto the air intake.

4

Reconnect the cable to the negative terminal on the battery and close the hood. Turn the Saab back on and take it for a test drive. The turbocharger may at first register lower rpm readings, but that is normal because the bearings are new.
