I have a 99 cherokee, 4.0 IL6. Everything on it is still stock (other then general mantience, belt, filters ect), which is amazing considering I just hit 150k miles this last weekend.

Ok starting to get cooling issues and figured since all my parts were still stock I would just replace everything. What am i needing is a list of recommended parts. I wanting to replace the water pump, radiator, t-stat, t-stat housing, engine fan/clutch, upper and lower radiator hose, both heater core hoses and anything else anyone can think of. Would also like to replace my belt, idler/tension pulley. I am the orignal owner of this vehicle and want to keep it running as long as possible.

And yes I have dug through several posts and people toss out a brand here and there for various parts, most of which dont fit my model. And thank you in advance!

Water pump: any "name brand" (Bosch, Gates, etc.) I like the Bosch 97082 it is good quality and relatively cheap (~$25)
Radiator: if you need extra cooling capacity, otherwise a Spectra-Premium or Vista-Pro OE replacement will do.
T-stat: Stant or Gates SuperStat
T-stat housing: Is there something wrong with yours? If not you can re-use the old one, if you do need to replace it they're all about the same, it's just a piece of cast-aluminum.
Fan Clutch: OE (best option) or Hyden
Radiator and heater hoses: Any "name brand", I used Dayco
Belt: Goodyear Gatorback
Idler: Any "name brand", I used Gates
You might as well replace the Radiator cap, I would recommend Stant or Gates for that
Don't forget a T-Stat housing gasket, I would recommend Fel-Pro

I just did my radiator, upper and lower radiator hose and 180 degree thermostat and i'm very happy with the results.

Did Champion finally get their rads to fit right?

I considered a Champion when I did my replacement but at the time everyone that I had heard of who tried said they didn't fit right wan were a pain to install so I went with the CSF 3-row copper/brass instead.

If they finally got them to fit, that is a great price for an all aluminum rad.

All of this with one exception. I would replace the t-stat with an OEM. A lot of people have had a lot of problems with the after market one on the 4.0.

Looking at the lower radiator house you suggested and it doesnt mention anything about containing the spring to keep the hose from collasping. Does it contain one and just not say?

XjZack

Nope i had to do some trimming not to much though just up top where the cap is and the brackets for the a/c condenser

i to ran the Stant for the thermostat the Goodyear Gatorback and the Goodyear hoses for Coolant i ran Zerex G-05 i'm very happy

Replace the radiator cap if it has one. Not sure if 99's do but it is a simple part that can cause headaches when it fails. It costs $4.99 or somewhere in there...

dmill89

None of the aftermarket ones have the spring. Newer hoses are constructed in such a way that they can (at least according to the manufactures) run without a spring and not collapse (mine doesn't have a spring and I've never had any issues with it).

If you want a spring your options are either to take the one out of your old hose and re-use it if it is in good shape, buy an OEM hose from the dealer (they cost about $50), buy a spring separately (I believe NAPA sells them), or get one of those "universal-fit" hoses and take the spring from it (don't use the hose, those "universal-fit" hoses are junk but since they have thin walls to be flexible they usually have a spring inside you can use).

The spring, or lack of, is a non-issue. Once heat starts to build, so does internal pressure, presuming the cap is good and there are no leaks. A pressurized hose shouldn't collapse.

Radi

Yep. If it's going to collapse, it'll do it when the system is cooling off after you park it....instead of drawing coolant back from the reservoir.

Well here is what I think I am going to go with, replacing a few pulleys as well since they have been on their since I bought it. If anyone sees anything glaringly wrong or can suggest a better part please let me know. And sorry for the quad pictures on each item, not sure what thats all about.
