Hello everyone, cheers to a great site!! I am desperate for some help if anyone knows this, sure has me puzzled. I have a 97 f-150 4.2 litre, and I can't seem to locate a replacement steel tube that installs into the top of the water pump, it is a Y shape that branches to the heater core and intake manifold. I was in the Ford dealership for over an hour and they could not find it on their computer diagram, called two other dealerships with no luck, and spent three hours this evening on oem parts websites looking, but no luck??
None of my local wrecking yards have one either.
My old one is broken in half where the o-ring seal is installed on the tube.
If anyone possibly has a web link or part# it will be greatly appriciated!!
Thanks in advance, Paul

Be carefull taking it off of the water pump. i cracked the cast part of the WP where that tube plugs in at. its just a pressure fit into there. My dealership charged me $90 for the one i put on my 4.2 so thats not a bad price.

I just replaced this part (1L3Z-18663-AB) purchased from the dealership for $105.00. 2001 F-150, 4.2L.

I think this is the reason for the coolant leak on my F150. Seems to be cracked at the weld inside the Y. What symptons was this part producing for you that made you replace it?

mich655

There were no symptoms other than severe corrosion. I figured I would replace it before it failed. And it was a good thing, the tubing was actually paper thin in some areas. Just remember if it does fail you will pretty much be stranded due to loss of coolant.

I replaced the water pump on a friend's truck, the y-pipe on the pump was also badly rusted, it almost literally disintegrated in my hands.
