My low coolant warning light came on and the reservoir is low. What is the recommended over the counter coolant? Color looks yellow from my determination.

Have you found a leak? My 2010 is low also and it looks like something is leaking. I wonder if the 2010 coolant reservoir has similar issues to the 9-3 V6 coolant reservoir.

Guys, please keep us posted on the source of the leaks. Any news yet? Thanks!

For the second time in the last two days my low coolant light came on. After filling up the reservoir this morning with Dex Cool GM Prestone color Red, my light came on again about 10 minutes later. I noticed a pool of fluid under my car but it appeared to look more like water than coolant. I used the AC system for the first time this year yesterday which I believe to have triggered the light.

I must admit to smelling sweet maple syrup type smell from the AC vents. I called On-Star tech support and they ran a diagnostic report with "no faults found". The temperature gauge is normal but the coolant level is again low. I suspect a loose hose or perhaps a more serious problem with the radiator. Any advice would be appreciated. I have no other complaints about the car other than this.

For those that are interested in knowing where the coolant was leaking from. I had a loose cup-puling that was not fully secured. Pressure builds up on some of these coolant hoses and must have caused the cup-puling to come loose. They tightened it and pressure tested. Drove home from my dealer in Concord NH. Seems to be fine now. ;ol;

Glad you got this fixed. Do you have any more details on which coupling it was?

I discovered the source of my leak in a big way today. The water pump just went out after only 36k miles. It must have been leaking somewhat intermittently over the past four months. I had never seen any drips on the ground. I'm assuming it would leak sporadically and I never happened to notice the coolant on the ground. But today, it started pouring out.

The water pump is quite hard to see on the V6. It's tucked behind the engine mount. Removing the right hand side wheel well shield should allow for inspection of the pump, at least to see if it's dtipping.

I have a small leak coming from the coolant tank as well. Service history shows this tank was replaced once before, but the leak from the tank area still persists. My suspicion? I think the O-ring on the big hose coming out of the tank is probably bad. I will pressure test to try and confirm this, however it seems to be somewhat intermittent so for the cost of an O-ring, I may as well just replace...

My 9-5 Aero started leaving orange puddles one day at about 48K miles. Seemed to happen when the car was shut off, not when it was running. I figured it was probably water pump as I've heard of others 9-5's with same issue. I had it towed to the service center. Waterpump was replaced under Saab Secure warranty.

The small supply from the reservoir to the turbo is prone to dry out and leak. You may only see it by the staining on the heat shield. Mine was leaking and I finally noticed the staining. The part took a couple days to come in to my Saab dealer and was about $15. I was adding a small amount of coolant every 2-3 weeks for about 4 months before I figured it out.
