GM Part : 23106015 TANK, Engine Coolant RecoveryNot 100%, looked for leak but so far not obvious. Smell is definitely coming from coolant tank area, maybe the tank has a hairline crack.
I wouldn’t replace surge tank until varifed.Any idea whether the surge tank would be covered under the powertrain warranty?
Been on here since 2003 and never seen a coolant leak where you had to pull the tranny and flywheel to get at it.Took them two days and they finally found it...a seal in front of the flywheel, said they have yet to see it. They'll have to pull the tranny and flywheel to get at it.Anyone else have a similar seal failure?
So it’s your engine oil cooler has a leakChanged my oil last week, here's the leak, definitely coming from the back of the engine. Dropped it off at the dealer today and met with the mechanic who's going to do the repair. He's a 30 year vet and told me he has seen it before but it's not common, said there's a plate on the back of the engine and that sometimes the gasket between the plate and the engine goes bad. I'll post again when I get it back.
Some dealers just have a hard time acquiring parts.Three weeks at the dealer...still waiting for parts, does this make sense?
