Dear jeepers

I have a leak of coolant under the bottle.
I bought another bottle and discovered the very low quality of re-manufactured parts in china
I’ll find another one.

but I will also change the old hoses.
my mechanic asks me to provide the parts.
he also would prefer to have new metal tees
ok but what to buy ?

to summarize I need all the hoses with dots + the tees if needed ( my mecanic says he is not sure the tees are made for regular hoses and will hold tight the hoses)

​​​​​​Thanks

for reference, i live in France, mechanics don’t want to lose time looking for parts. So I need to provide everything ready to install or almost.

 

So I got curious.
For some reason I do not have an '87 parts catalogs.
I have an '84 to '86 and a '88 to '90.
So I am using the '88 to '90 here.

So I am not going to lie. I am a bit confused.
A lot of just looks like heater hose and clamps.
And assuming the heater hose is the same diameter at both ends in those instances bulk stuff should work.
The parts that are confusing me are the lines that are crimped like AC hoses. Not sure how else to describe it.
Yet it looks like you can buy the "T's" separately.
I wonder that if you do have to replace any of those "crimped" lines that they ended up deleted in a sense.
In other words it is just hose, "T's", and hose clamps now.
Is there control valve on one of those "T's"?
I Googled a few of those part numbers in the illustration and some seem to be still available.
Even some pictures for you to see if they are the right ones.
Cause I can't tell. Angle of shot, etc.
And what kind of availability you have for these parts in France is unknown.
Get the feeling this really won't help.
But it is the best that I can do. LOL.

 

@EuroJeep You have the original RENIX closed cooling system. This would be a good time to convert to an open system. I'm sure there are some threads here that explain the process and what is required. There are plenty of YouTube videos on it. Here's one ... The only "big" item you'll need is a 1991+ radiator. If yours needs to be replaced that just adds to why a conversion would be a good idea.

Whether or not your mechanic wants to do something that is non original may be an issue but once he figures it out, which is easy, he could do the job faster than cleaning up the original rat's nest of plumbing.

EDIT: I did this to 2 Jeeps in the last few months and can provide part numbers if it helps. Everything was easily available.

I got my Renix hoses from RockAuto

the hoses are spread over several sections of rockauto.

a. Radiator hoses, b. heater hoses, c. reservoir hoses

link provided is for a six cylinder 4.0 liter cherokee.

 

One major problem with the aftermarket bottles is the molding flashing on the nipples isn't cleaned up. Someone really needs to take some time and trim it away and do a really good job of making sure the lower hose can seal properly. I don't know if I would trust the mechanic to take his time to do it. He might, or he might not want to do that, depending how he's charging his time. If the lower overflow bottle hose barb isn't cleaned up and smooth all around the lower hose will never seal well.

2) The first aftermarket overflow bottle I bought cracked all around the lower hose bib after like 2 years. The second tank I bought seems to be a little better molded (luck of the draw) but still needed cleaning up on the hose bibs. If your original tank is still good, I would use it. Check it's (or the new tank) isn't micro-cracked around the lower hose bib (like someone dropped the new tank on the ground). If my new tank craps out again around the hose bib/s, I'm going to cut off the plastic hose bib's off, tap and thread the plastic and install a decent brass hose bib in their place. That's probably the ultimate solution for these otherwise decent-looking aftermarket tanks.

3) I don't like to sound like a complainer, ...but also, the opening where the main fill cap is, that area was poorly finished on my two aftermarket tanks too. It required a fair amount off finesse to clean that region so the cap would seal properly.

Make sure your engine mounts aren't broken. The rocking of the engine under torque would tug the heater hoses and likely break the coolant tank hose bibs.

 

metal tees should be reusable I reused mine.
