V6 2.8T Coolant Tank Issues and Questions Posted by Aero51 [Email] (#2716) [Profile/Gallery] (more from Aero51) on Wed, 14 Mar 2018 15:56:05 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I've read quite a bit on this forum and elsewhere about the coolant tank issues with the V6. I have a 2009 Aero convertible with only 39K miles. Owned 3 months, I started to have Low Coolant light issues about a month ago. Here's the situation: No overheating, according to records, tank has been replaced. I replaced the cap after the problems started. Tech has done a pressure test: no leaks discovered. I have closely tracked the behavior for several days, and it is repeatable: Drive until completely warmed up (up to 25 min. or so); cool down at idle for one minute; stop with engine off for 10-45 mins; drive again. The light will come back on within a few minutes of starting. The next morning when it is stone cold, no loss of coolant (measured with a mm ruler used as a dipstick). My only logical conclusion is the the tank needs to be replaced (again). Possibly the excessive heat under the hood soaks the tank immediately after driving and in some way causes the sensor to malfunction (warping, bad electrical connection, etc?) Any other conclusions?
1. I don't know when or how many miles ago the tank was replaced. The official Saab service center that did the pressure test looked it up to confirm all recalls were fixed, but I didn't think to ask when the tank was replaces.
2. Is there a diagram of the float/sensor in the tank, or has anyone cut open an old one? I'd be curious to see it.
3. What database or site is available to get the service info? I looked at GM and they don't list Saab anymore on the dropdown to register as an owner.
I realize that there could be internal leaks or tiny leaks where the coolant evaporates before forming drops, but neither of those explanations seem to fit what I've said above (no loss of coolant when measured consistantly.) I will gladly replace the tank if that's what it takes. Any help from the group will be appreciated. Thanks, Steve
