In 2007 I replaced the water pump on my Series 60 with a Reliabilt one from the local Detroit dealer. I must have done something wrong with the o-ring as it is leaking increasing amounts of oil around the pump. Joel at the Choo-Choo Express garage recently confirmed it is the o-ring around the pump. (I replaced the pump since I was replacing the radiator anyhow.)
Is there is a special trick to installing the water pump on a Series 60 to avoid damaging the o-ring and casuing a leak? It is going to be a complete pain to remove and replace the water pump for a simple o-ring. It was significantly easier with the radiator out.
