I'm looking online for coolant pressure line hoses - the small ones that are part rubber, part metal. The ones on the jeep are old and cracked (in the rubber sections). I can't find on parts online. I've seen some videos showing how people repair pressure line hoses.

Any thoughts on getting parts?

Funny, I just worked on an 87 Cherokee and replaced all coolant hoses. Which ones are you referring to exactly? Are they the ones that run to the heater core via 2 separate steel T's?

I'm planning on replacing those as well, but the parts I can't find are called pressure line hoses I think. Attached is an example of one near the bottom part of the radiator. I'd assume they aren't changed as often as the all rubber hoses, but the pressure line hoses on this jeep aren't in good shape.

I can't open the pic for some reason. However, at the bottom of the radiator you have a lower radiator hose and there is a trans cooling line to the bottom side of the radiator. If you are standing at the front looking down, it will be on the bottom right. There is also one on the upper portion of the right side too. Is that what you are looking at?

Yes, I found the lower radiator hose part but the smaller rubber & metal tube line running to the transmission has been hard to find a part for. There are various similar lines that I would like to replace but no one seems to carry the parts. I saw online examples of people repairing these lines and was wondering if that is what you have to do for these older models.

Okay, it sounds like it is the trans cooling line you are referring to. Does this look like the part?

It's a similar part, the bends in the metal line are quite a bit different. There are also two other lines that carry coolant that look similar, but have metal, rubber, and bends in different locations. I think I'll have to stick with the old ones for now.
