Big Red finally let me down. For the past couple of months I added about 2 qt. of pre-mixed anti-freeze. Was worried about head gaskets till I saw some drops on the floor & started getting a rattling noise under the hood. Took in to-day to a non Caddy shop & they found the water pump leaking, the small belt that drives it was damaged & the tensioner pulley bearing noisey. 5 hrs labour to replace it & 127.90 for the pump. Remember when it took 20 mins. & 19.95 for a new pump.
