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.
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.
I loose coolant every 3 to 4 days and took it to a shop and they couldn't find any leaks. so they told me to leave the car. they called me and said its a head gasket.
i really dont know if i should believe them, because alot of people have this problem. please i really need help
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
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...
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
Coolant loss, pressure tested pressure issue... Loss mostly when weather is really cold... Very little loss during summer
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!
Car burns coolant. The dealership could not find any leaks after pressure testing the system.
Refilling coolant every 2-3 weeks. Mechanic says it's probably the head gaskets,but haven't got it fixed yet.
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.
I have to buy more coolant like every month
No sign of a leak. Slow leak. Have to add a pint or two every two weeks. No sign of water in crankcase.
Replace turbo
I just purchased this car about 3 months ago and I've had to put coolant in it 3 to 4 times. I don't know what's causing this problem. I'm looking for answers
This problem has not been fixed yet, I just looked online for answers because it seems every couple of months or so, my low coolant light comes on, and when we go to have it looked at they say that it's a little more than 3/4 full and they aren't sure why the light comes on. They thought maybe a really sensitive sensor, and just fill it when I bring it in.
bought the car 2 weeks ago i check the fluid before i bought it and yesterday the low coolant light came on. i pop the hood and checked it and just in 1 week it went down by alot. i turned it on to smell if it smelled sweet but no odd smell. might have to resell the vehicle.
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.
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.
