2008 LS Overheating - Diagnosis help?
#12
Thanks for the feedback about the leaks (and lack of evidence therof). I placed a sheet of cardboard under it after the last test drive and no evidence of leaks, but obviously the coolant is going somewhere.
I think the recovery tank was completely empty the first time I refilled it. Since then it hasn't changed, but when I open the pressure cap, I always have to add more coolant to get it to be visible at the opening. I have been looking for an excuse to buy a set of Rhino ramps, so they will be delivered Tuesday or Wednesday and that should help with the burping.
I might have to get a coolant system pressure test kit from AutoZone through their "rent a tool" program if I can't find the leak this way.

I hope you’re not “filling “ the recovery tank all the way to the top. Your word was refill.
The Full mark on the tank is way down near the bottom. Hard to see.
If you did fill it to the top it will not cycle coolant between the radiator and recovery tank.

The tank level is supposed to increase when the engine is hot and decrease when it cools down. If it is over filled the pressure cannot be overcome. The pressure cap can wear out, wise to replace it.
Coolant can disappear via a bad head gasket, look for steam cleaned spark plugs or orange spark plug ceramic (if you are using DexCool). DexCool has a life of 5 years regardless of miles.

No, I filled it to the line. I checked a YouTube video that showed where it was since it's not intuitive and the manual isn't the best pic.

Burp the system, easy peasy! Front bumper higher then the rear bumper a floor jack under the right front so the filler neck is higher then the rest , fill the filler neck while cold!

I will probably get a new cap, just in case. Would a Duralast cap be an ok replacement? Or should I wait on a Delco?

Thank you, Donbrew.
amazon apparently has them 1 1/4 inch is the size

I finally got around to installing the one I got on eBay. Not happy. The nipple to the coolant recovery tank was not welded. It's a threaded nipple. I put Teflon tape on it, but when you thread it in far enough to not leak, it interferes with installing the pressure cap. I'll have to rework it, try to get it to not leak.
Just a heads up, maybe some sellers have them welded.
