Last saturday, fixed coolant leak with a 49 cent o-ring. Thought it was going to be a hose connected to the ET. Jacked it up and dropped the belly pan. Turned out it was the temperature sensor on the lower radiator hose connector.
Dealer wanted $6, was a 30 mile drive and was closing any way. Got a similar o-ring at the local Ace hardware store for 49 cents. Took about 20 minutes to replace. Didn't even have to drain the coolant. Easy peasy.
