I have no idea how to service the I/c pump or make sure it is working correctly. It is a Bosch but i'm unsure if it's already been replaced. Any tips on changing the engine oil? Fleece filter serial number? etc.... I typically do this research before purchase, but test drove this car as I was shopping for a challenger and knew it was the one. AAAND what is up with the tow button? Any ownership tips would be much appreciated.
