It's very straight forward. Obviously you want to wait until the vehicle has cooled off.

Disconnect the hoses, remove fan (if attached to radiator). Remove the top radiator bracket and the whole thing will slide out. IF you have the radiator that has the transmission cooler as part of it, you'll have to disconnect those lines also (obviously).

A radiator shop can clean or repair it, but a new one will not be much more. I purchased a new one for $159. Don't order from a dealer $$$$$.

If it had been running hot, now might be a time to consider new thermostat also. ALSO, If you have the time, you could pull the water pump and flush with water to remove any residual debris in the system... Just a thought...

Thanks for the help
I got the old one out last night and am planing on puting the new one in today. Best way to go for me was to remove the small front skid plate it opened every thing up and made getting those bottom hoses(Transmission/Coolant) off easy and draining the old coolant. The only problem was with the fan cover(Belt driven fan) was a pain because it would get in the way and it would not come out until the radiator was out. It goes all the way around the radiator. I was thinking about possibly removing the bottom part of this cover and just keeping thetop part that keeps your hand from hitting the blades. to make things easier. any ideas? or do you think i should keep the whole thing intact

Keep the shroud intact. Protects the lower fins from debris bouncing up, as well as directing air where it's supposed to go. You can hold it back easy enough when you're pulling the radiator.

Or you can do an e-fan swap. A bit more challenging due to the 4.0 length, but doable.

The bottom part of the shroud is a huge pain in the butt. I ended up cutting a slit in mine on one corner, just so it was easier to get in and out...did this a long time ago, saved a bunch of trouble on future projects. just allows you to open it up to get it passed the fan and get it out. Not recommending it for everyone, but sure worked well for me. I still get the shroud protection, but not the pain.

That's the piece I couldn't get off. Which ultimately led me to take it to the shop.

Shop? What shop? Someone please hand me my sawzall! Nice thing about my ZJ being my 2nd vehicle with 185k miles. It was part of fixing a water pump leak, which was a pain overall anyway, so cutting the shroud was just a small part of the bigger process.

Every time I work on the engine on the ZJ, I long for the days when I could literally crawl into my compartment of my 67 Chevelle and sit in there to work...

Yep. Heres another guy that has, more than once, cut the shroud to facilitate removal. It does the same job when reinstalled and taped. I think I took some small screws and fitted a neat plastic patch across the cut to repair it. But if you clean it well, quality tape will suffice.
If any part of the shroud, or the foam strips around the radiator , are missing at the end of the job, you will probably risk overheating.

Don't forget to check the fan clutch. They DO wear out and they DO cause overheating (at idle).

Getting the lower hose boss past the steering gearbox can be a challenge, but if you work patiently and angle and pull, you can get it past there.
