Here's something to watch out for if you have your car serviced at fast lubes. MY daughter's Sebring over heated and tripped the idiot light about two weeks after a fast lube visit. They alerted her to the funny looking coolant condition.....color less Zerex G05 installed by me last summer. They failed to lock the radiator cap to the last detent and it slowly lost about a gallon of coolant over the next weeks. Luckily my daughter stopped driving it immediately until I could fill the system back up.
