I have a 1996 Sidekick with the 1.8l engine and I need a little help. The coolant return hose from the heater core runs into a metal tube which in turn goes around the engine block and into the water pump area. This metal tube has a leak and as I am looking at it I am unsure of how to remove this tube from the water pump. Is there anyone out there who has done this or knows how to accomplish this. Any help would be appreciated.
