I have to replace the water pump on my 1999 windstar (3.8L), and I wonder if anyone has any advice on how to proceed? I have changed water pumps before on various vehicles, but the space limitations on this one have me scratching my head. A few co-workers have told me I may need to remove the engine! I hope there are alternative methods....any suggestions? Manuals? Pictures? Videos? Any help would be very appreciated.

Thanks,

David

Thank you! I will print this out and use as a guide. I may check it over one more time and make sure it is actually the water pump that is spewing coolant, or if something else is the culprit. This is a big project to undertake to be wrong lol. I'll post back over the weekend when I get a chance to check it out again.

Well, good news and bad....Good news, it was not the water pump. Bad news, it is a hose which I cannot find anywhere at the local parts stores. This vehicle has an upper radiator hose (drivers side) a lower radiator hose (passenger side, goes to the water pump) and a mystery hose which goes from the coolant reservoir to the radiator. That is the hose I need, and no one has it...furthermore I do not know what it is called. The hose sits below the A/C pulley and looks as if it has rubbed a hole in it over time. Anyone have a clue as to what this hose is called and where I can find one??

Thank you

If it just rubbed a hole in it, how about getting a pipe to fit inside the hose and 2 clamps. Then reroute the hose away from the scuffing point.
