2009 CTS4 2007 STS
I have a 97sts that has a small crack on the coolant tank where the hose connects which runs across the top of the motor. there only seems to be a problem with it if the AC is not on. For some reason. I've tried to use the JB weld but it peeled of cause of the heat and the coolant pulses out through the crack which has now stained the battery with the orange color. The dealer quoted me a price of $92 for the tank and $45 for the labor. I know this is a cadillac but that seems a little outrageous for a plastic tank which sits out in the open. Is there anywhere I can find this part so I can do the job myself, I've searched but came up with nothing.
