Model Years Affected: 1999, 2002, 2003, 2004, 2005, 2006, 2007

Engine Affected: 2.0L 4 Cylinder Turbo

Average Mileage: 97,270 mi (30,000 mi - 150,000 mi)


2.0L engines may become low on engine coolant with no cause found for the coolant loss. Our technicians tell us than in some cases the engine block may require replacement due to porosity.

    Coolant low message going on twice a week. Got water pump replaced which was leaking apparently. Still losing coolant however following that repair with no sign of a leak. Just had it looked at by my shop and it apparently needs a new head gasket (coolant was getting into one of the cylinders, hence no sign of a leak despite the continual loss of coolant). Quoted $2,100. Anyone have a similar issue? Curious what the bill was if you had the head gasket replaced. thanks

    i bought the SAAB 93 2005 model, i realize the notification on the dash board says coolant level low ... i dont see any leakage but i can see the level of water is low .. every time i see the message i full it with water and and it works properly with no heat on the engine. i still dont solve the problem and i have found many people suffering from the same problem.

    No sign of a leak. Slow leak. Have to add a pint or two every two weeks. No sign of water in crankcase.

    Regarding the coolant leak problem, you can buy GM Seal Tabs and add them to the coolant tank. I was adding coolant every other day and added six of these tablets and it has greatly helped the problem. I hate to see all you guys talking about replacing head gaskets and water pumps because it is most likely that the problem is the porous engine block issue and these tablets cause something like $5 for a 6-pack, so try this first before you go spending a lot of money.

    Replace coolant fluid would be status when I turned on the car. Could feel something wrong each time i started from a complete stop. Had to replace engine mount becuse it was cracked.

    Car burns coolant. The dealership could not find any leaks after pressure testing the system.

    No one can find where the coolant is leaking out from. At first I just kept filling it up with water and anti freeze, however now if I drive a half of mile the hot engine light goes on and I have to pull the car over. Someone told me it was the water pump. I am taking it to the mechanic tomorrow.

    Varies from every few days to about once a week that I have to add coolant. Have had it
    Dye tested and have had it checked for
    Problems with head gaskets and other things as well. Not sure what to do next, but I'm spending about $30/month on coolant right now, which I'm not liking too much.

    Replaced head gaskets...not leaking anywhere outside but constantly filling up coolant because light on dash comes on and it's low. Doesn't over heat bc I always fill it up. Annoying and expensive. I have about 92000 miles on an 06 Saab 9-3 turbo 2.0
