Well I've had a bad coolant leak for a while. Finally had a reputable place called MACS Radiators check it out. Full system check was only $25 so I couldn't complain too much. Anyways my radiator is cracked bad, which I expected unfortunately. Also my fan clutch is basically dead(which I suspected), and my coolant is dirty and needs a flush(also figured). They quoted me at $724 for all that stuff lol. I can get a new radiator and fan clutch from Oreillys or Autozone for around $150, OEM based stuff though. Is it best to just get some new OEM stuff like that or are there some better radiators for around $150 or less? Not looking to spend a fortune on it since even now it doesn't overheat unless I'm at a stop and it's blazing hot out.

Do yourself a favor and just do an overhaul to the whole system. New radiator, radiator cap, water pump, thermostat, thermostat housing if yours is questionable and/or breaks, any hoses that look like they're falling apart replace them, new fan clutch (Hayden from O'Reily).

Get better than bottom of the barrel parts. Knock it out that way your coolant system stays good for a while.

Well i was planning on a new radiator and fan clutchn and i already have a new thermostat to go in. The guys said the water pump was good but i might do it just to do it. I was just curious if there was better stuff than just the oem that isnt big $$$.

The oreilly brand radiator is Murray. They have 2, ones 109.99 and the other is 200 but they seem 100% identical.

ZJ fan clutch for a cooling improvement, I got my rad from CarQuest, and I haven't had problems (unlike the one from Advance), and Mopar thermostat from the dealer.

The mopar thermostat can't be stressed enough. I went through 3 before my mopar one.

How much are the Dealership Mopar ones? I got my Tstat for i think less than $10 but I cant remember.

Edit: Oh and another dumb question, why would I need a new radiator cap? Does it matter what one I get?

You and me both.

83501426AC retailed for $23.35 when I bought my last one in January of this year.

I did all that a few months ago when I started to see a coolant leak, I knew off the bat it was my radiator so I bought a used one from the junkyard replaced water pump & thermostat and added new coolant

I'm confused. I don't think I quoted you. Lol.

Note, it also comes with a gasket.

Alright, so I'm installing my 4.0 into my 86 comanche. I have already heard and read about how they aren't directly adaptable. However, my 93 cherokee mounts made my drivetrain actually sit correctly; almost.

The engine has a slight backward tilt to it. It barely clears the hood in the front, so as is, I would have to trim my hood slightly. I am only worried as to if the oil pick up would work correctly, or would the slight lean create issues?

There a multiple pictures I posted in my build thread if you want to see how much lean there actually is

Might want to either provide a link or put it in your signature lol.

The 4.0 is pointed upwards from the factory in the later years.

CherokeeJon

It is now in my sig. I'm usually on my phone so I don't have the chance to edit that. Sorry haha

I can't tell if its leaning too much though. I was comparing it to my 97 and it seems to tilt more than that one does

lol read DieselD's comment then realized he probably didn't mean you...

It looks a little more angled than the stock setup. Should be okay, it's not like a 4.0 can't take an incline.

The auto and manual crossmembers I believe are different heights. I think I read here that the manual ones give a slight life to the tcase in auto-equipped XJs. Might help you out a bit
