1997 Jeep. Some reviews said hard to get on the water pump end. Used some Vaseline and it went on easy.

This was recommended as the hose from the top of the water pump to the hard metal tubing going to my heater core in a 2003 Silverado 4.3l v6 "x" engine. Problem at that time was that it was way too long. Called a local GM dealer , the AC Delco equivalent hose was the exact same thing but he had notes on his computer terminal explaining the need to place the old hose on top of the new hose at the 90 degree bend and cut this hose to fit. He explained that GM was going to universal hoses to fit all the engine platforms and this cut to fit was more common on the newer models. Therefore some modification required on this application.

This was an EXACT fit in a 1993 Lexus GS300 with the 2JZ engine. The Heater sending hose coming off the back of the block was OEM and in need of replacement. This fit perfectly!
