Default Coolant leaks after car is turned off...

Saab 900se V6 coolant is leaking after car is turned off towards front bumper.. I cant find the leak, oil has no milky substance and coolant has no oily substance..
Is there a certain area I should look?
Coolant low flashes about every 3 days or so..

I had same condition but it was on a 2001 2L turbo 9-3. I believe it was the o rings at the water pump housing to block fitting. I don't know if the 6 has a similar configuration or not.

It sounds like some sort of seal to me. When the engine is hot the seals expand and fit snug, but with a bad seal when it cools it can shrink back down and any cracks would open up causing a leak. Hope this helps.

When you say "after I shut it off" do you mean that you see a drip immediately, or that you see a drip in the driveway the next day?

you may have a small radiator leak, when you are driving most of it may be evaporating and when you stop it leaves a little puddle. if it is under the bumper the radiator is really the only thing there, if it is behind the bumper then it could be a hose connection or turbo etc.
if you leave it running parked for a 1/2 hour do know if there is a puddle?

Depending on your driveway/garage surface, you should be able to pinpoint the area it's coming from by just sitting and watching then. A puddle in 30 minutes is a lot. Next time you shut off the car, sit and wait for the first drip or two. Get out a flashlight and look under for where the drip is dropping, then follow it back up as best you can. The waterpump is a little hard to see on these cars since it's down deep under other things, so you might want to put the car on jack stands, remove the shields under the front bumper/engine, and climb under to look. Removing the shields will also stop the drip from running to a new location in most cases and it should drip close to the source (a hose, the bottom of the radiator, the water pump, etc).

Over the course of my ownership, my previous 95 900 V6 had coolant leaks at the radiator side tanks, and at the heat exchanger in the "V".

I have a similar issue. After I turn off the car, I'd see a puddle of coolant under the front bumper. Of course I'd have to fill up the coolant every couple of days as well. TO be honest, I haven't tracked down my coolant leak as of yet. Though I have figured out that the radiator may not be the culprit. I have been seeing dried coolant on the transmission, so I am starting to believe that the leak is somewhere on the upper part of the engine. I have to replace my valve cover gaskets, so when I remove the intake, I am going to check all the hoses up top to see if I can find the leak.

Now that I observe it more, it seems like its bubbling out of the exhaust manifold area, driver side front..


Any ideas?

Maybe blown head gasket?
