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.

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.
car loses coolant, have to refill once a week or more. Has not been fixed, mechanic cannot find any leak.
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

Recently started showing low coolant level just about every other time i drive it.the temp gauge would show it was hot i always pull over let it cool or add water/coolant depending where i was at the time. The last time i drove it 4 miles to the store the temp gauge and everything else looked perfect it didn't say it needed any more coolant when i turned car off it was smoking a little i let it cool put water and coolant back in it and its still doing the same thing. You can tell where it has leaked a little water under the hood drivers side in the back in clear sight but only a small amount. It just feels like its lost alot of power including the turbo...

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.

Refilling coolant every 2-3 weeks. Mechanic says it's probably the head gaskets,but haven't got it fixed yet.

Coolant level regularly reaches low levels after 3-4 days of full refill. Have been constantly filling up coolant weekly. Occasionally "Engine Overheated Please Pull Over and Turn Engine Off" will come up on the dashboard. Today, turned on car and it was rumbling. 2/4 of the Coil Pack was replaced. Could these 2 things be related? In other words, any chance the replacement of the 2 coils will mitigate the coolant system malfunction? ***I know nothing about Saabs, this car is new to me!

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

Bought the car used, in Nov 2011, and saw coolant loss within the first several hundred miles of driving. Car was purchased in Massachusetts, so I'm still under the protection of the state's Lemon Law. Had the car looked over at local Saab Dealer last week and they verified that they couldn't find any external coolant leaks, yet I've used about 1/2 gallon of coolant/distilled water mix over the course of 1900 miles of driving. Dealer I bought the car from is scheduled to diagnose this week and says they will repair. Just curious as to how they expect to get a short block in the midst of Saab bankruptcy issues.
