I have a 99 Saab 9-5 2.3L turbo. When I shifted it would blow white smoke for a second. Yesterday it started billowing smoke then died. Now it won't start and it turns over very rough. Please help.


Generally white smoke is a sign of coolant in the engine.
Its possible you have blown the head gasket and coolant is leaking into one or more of the cylinders.
You could pull the spark plugs and check for coolant - also run a compression test.

99 SAAB 9-5 PROBLEM WITH AC....AC IS WORKING.. CONDENSING WITH NO PROBLEMS ...WATER RUNNING OUT UNDER CAR..PRESSURES ARE 225 HI 35 LOW... NOT GETTING COLD AIR INSIDE...LUKE WARM ON DRIVERS, AND COOLER...


OK, most cars have heater cores that get hot but the blender door directs air away from this core in the a/c mode when you want cool air from the evaporator.

I'm not sure if there is a control valve which stops the water from going through the heater valve.

I think the part is called a 'heater blend door actuator' that you are after.

Saab 9-5 blowing white smoke from exhaust


One way to check for a blown head gasket, is to simply smell the coolant reservoir. Pop the cap, and see if it smells like raw gas. Every headgasket, I've diagnosed has had this smell, even if the oil is not contaminated. Another way is to hook up a coolant pressure tester, and run the vehicle for 15-20 mins or so. If the head gasket is blown, the pressure will exceed 15 psi. sometimes as high as 25 psi. If there is oil in the coolant overflow tank, the head is cracked, about 90% of the time.
I'm working on a 03 Saab 95 2.3l t. This vehicle smokes on initial start up, then the smoke disapates, and the vehicle is fine. Another mechanic diagnosed it as bad valve seals. I disconnected the pcv system, and the vehicle no longer smokes. If the valve seals have gone bad, the vehicle will smoke on acceleration. Also if the turbo seals are leaking it will smoke more heavily on acceleration.

On 1999 9-3 models there is a fuel filter located under the pass rear door. However if this was plugged it would not kick back in after a short time. Typical suspects are crankshaft position sensor which will work well on a cold engine and intermittently cut off and on when the engine is hot. Its a cheap sensor, and very easy to change. Possibly check condition of spark plugs and the DI cassette as well. Also check function of Fuel pressure regulator. Any fault codes stored (CEL on?)
