Any tricks for getting the metal heater hose off the top of the water pump? I can't get it to budge and there's not much room to get anything around it.

Ours was so rusty, didn't even attempt to remove it, figured I'd end up with a broken stub in the water pump.......replaced the pump and used a brass 3/8" NPT X 5/8" hose barb nipple. Cheaper than the factory steel pipe and will never rust.

Another forum member came up with this idea but hey, I can copy with the best of them. LOL Works great and thanks to whomever it was that thought of it.

Either put it in a vice or use a C-clamp, soak it in PB blaster, then slide a wrench over it and slap it with a hammer. worked great for me.
Or in retrospect, I'd much rather have done the solution posted above!

So, you need to buy a 5/8" length of hose instead of the pipe.
But, what is the size of the coupler you'll use to connect this short hose to the existing heater core coolant hose?
5/8" to _______ ?

the pipe i posted is for a 97 4.0...lol
just posting up the original style part for those interested. the one on our cherokee has been on there for 212,000 miles. not to worried about having to replace it again lol.. plus my personal preference is to let the steel pipe make that turn from the front of the block to the top of the block rather then a rubber hose.
