Question about 2003 Saab 9-3

Engine light on--exhaust smell in car--just replaced engine

I just replaced my Saab 9-5, 2000, engine this past spring. Put in a used engine with 56 K miles by a reputable mechanic. About three weeks ago I noticed that the AC was not working correctly--I have to blast it to get it to cool at all, as it does not work on "low." Lately I've noticed a bad smell in the car--like fumes--and the car turns over real hard. Finally, the engine light has come on and I am fearing the worst. I read other posts here and suspect it might be a coolant problem (at least/in addition to) another, bigger problem. Any hints, suggestions?

The ac is a gas leakage problem and can be fixed by an accredited ac specialist shop
the exhaust gas smell could be the flex pipe at the exhaust manifold or a exhaust pipe gasket that has failed ( come loose after the engine replacement)
as for the engine lights , it con=mes on from reports from the engine and the transmission so have the fault codes read to find which sensor is reporting a fault
could be that same sensor that reports on the exhaust problem
hard to start is an electronic reporting fault and that will be in the codes as well

SOURCE: 2003 Saab 9-5 Check Engine Light

Take the car to Autozone, they will read the codes via OBD II for free.  Other parts stores may have the same policy ... call first.   My VW dealer charges $40 to pull the codes!!   I bought a low-end OBD II reader for $50, as the wife and I  both have VWs.

White smoke is usually antifreeze, the most frequent cause of this is head gasket blown or cracked head ... big bucks.  Hopefully this is not you.  Unless the car had a dramatic overheating incident, for most makes of cars, this should not happen until you have over 100K miles, probably closer to 200K.   
White smoke could also be break fluid sucked in from power brake booster.  If it's brake fluid, it will smell very bad.  
On cold days, when the car first starts, white smoke can just be normal condensation in the tailpipe ... if it happens after the car is warmed up ... it's something else.
Check your coolant overflow tank level ... if it's very low or empty ... put water in (don't bother with antifreeze yet in case you are burning it up in the engine).  
Good luck, ..ajm

Just did last night on my 9-3. Part was less than $20 at NAPA! Found the best guide here:

Really took only 5 minutes. Push in on the electrical connector to be able to sqeeze the latch mechanism for removal. I didn't even lose enough coolant to replace.

My "Check Engine Light" has gone on periodically

From what you are describing i feel you might be having an bad EGR valve..It only causes the rough idle and shaking and fuel smell in exhaust..It can also cause back firing. Does it happen? Also do you hear any popping noise from exhaust?

Have an '02 Saab 9-3 turbo, 140,000 miles drives great, but have strong exhaust smell coming into the cab through the heater vents... Can't actually see exhaust leaking, but when I pop the hood I can smell...

Have the catalytic convertor checked, sounds like it may be trying to stop up. Some cars have an exhaust vent between the exhaust manifold and the exhaust pipe, it could not be operating properly. The purpose of this piece is to help the engine warm up in the winter to get the heater working faster. Most of them are vacuum contolled and the vacumm line might have a small hole or the cast iron unit is old and just stuck. you might free it up if you can get it off to work with and lube and replace on the car.

Saab 2003 2.0 petrol toxic smell and white smoke comes from exhaust engine light came on but went back of its self and there was a small whistle coming from engine seems to be gone now anything i can do to...

get it inspected, you may have a blown head gasket. If you do not get it looked at and it is a head gasket issue you could destroy the 02 sensor and the catalytic converter.

1999 Saab 9-5 SE

I own a  99' 9-5 V6 turbo SE.  Had the same thing.  Started smelling gas in the car, sometimes.  Instead of not starting it died (as in the engine stopped) on a barren stretch of road at night.  Towed to the Saab dealer: Conclusion?  Replaced the fuel pump and sending unit. Don't ask how much.
