Radiator for 4.7 HO

Man I am just full of questions about my acquired 4.7L HO. Anyone out there running a performance 4 row radiator on their 4.7 HO with the hydraulic fan? Over heating is THE #1 CAUSE of sludge build up and valve seat dropping in the 4.7.
I want to put this radiator form Amazon in it but not sure if there is room for a 4 row radiator.

I live in the pit of Hell, Colorado River area in Arizona. I want to keep that new 4.7 I'm putting in cool. I'm in a rural area we have to go 20+ miles to get to anything so short trip under cooling wont be a problem. I run the A/C 12 months a year we are already getting over 80 outside. There is also a 2 row available for the same price.

The hydro fan may require some fit mods.

Let me know what you find. My plan was to switch to aluminum next time around.

I was debating on getting a 3 row when replacing my radiator but couldn't find any reviews. So I ended up going with a 2 row and it was a tight fit. I don't know for sure but I imagine you would have to make some modifications to fit a 4 row

99 Cherokee-2 door,5" lift on 35" KM2s

From what I've read on here the 2-row all aluminum radiator should be fine for hot weather climate. Since the 2 row is taller than OE the fan shroud needs to be altered/cut so can't imagine what it would be like to try to cram a 4-row all aluminum radiator in there. Sounds like overkill which will likely cause real fitment problems.

Here's a good thread and from what I've seen @97Mule (Mike) has done an excellent job in installing his aluminum radiator. Maybe he could direct you to his aluminum work on top of his fan shroud which is a work of art. Good luck.

@Uniblurb .......... " his aluminum work on top of his fan shroud which is a work of art".... I wouldn't say that but thanks UNI. As for the rad on amazon, i would be sceptical about it claiming to be 4 row. It looks exactly like the one i got off of ebay for $240, and its a 2 row. That rad your looking at is 1 in taller because it was made to fit a 99 thru 00 which had the the electric fan backup and the 01 thru 04 4.7 came with a hyd fan.
All that being said it WILL fit with a little extra work.
As long as the hyd fan, water pump and power steering pump are working correctly you should be ok with a stock rad if its in good shape.... if its not, get the amazon rad and have fun........... more water in a cooling system doesn't always mean better cooling.






Let us know what u come up with @2004WJlover

I just did this a few weeks ago. Same radiator. I only had to drill two holes that I tapped for 6x1 metric screws for the lower fan mount and trim the top of the shroud.

You're too modest Mike and I should have known to look in your build thread for the aluminum radiator to fan shroud cap/cover you fabricated.

@Redrider02 , Are you talking about the link to the radiator on Amazon and is it a 2 row or 4 row radiator? Thanks.

Yea the 4 row is for a 99-02 so its out. Im getting the all aluminum 2 row that will fit 03,4 & 5 4.7s. Since Im doing a huge ton of work I trust the all aluminum over the plastic crap. Ive had 2 WJ's with 4.0's and an 07 Liberty that needed those junk plastic radiators replaced in under 100K. All 3 cracked at the top near the upper hose. To me a plastic radiator is junk I cant stand plastic radiator tanks. We also have to remove the neighbors rear bumper to get the WJ radiator out, I just don't want that plastic junk in my vehicle.

I installed one of the Chinese aluminum welded ones a few years ago and wrote it up here. I have great things to say still on it. Perfect.
