Radiator ??

You never know until you ask so here I'm asking
Blew a hole in my radiator overheating the other day in McDonald's drive thru.

My question is; do you have to take the whole grille and bumper off to access the bolts? Or can it be done an easier way?

With this heat and all and not having a garage, I'm tryin to it easy and quickly. Which I know it may not happen but givin it a shot haha

No, you definitely do NOT have to do that. I've done mine twice. I have the hydraulic fan. Here's my steps. 1) Remove the top metal support for the headlights. 2) Unbolt the hood grabber thing lol. 3) Unbolt the 4 bolts holding the radiator to the hydraulic fan, 10 mm if I recall correctly. 4) Unscrew the 2 hydraulic fan lines and black rubber hose, then remove the fan and shroud piece. 5) Then slide the radiator out. That's how I did mine. Much easier said than done, but there are a few write ups on here this simple way. Good luck!

It's easy on the 4.0L. I don't remember exactly what I did but I remember being able to access some bolts through the grille, probably for the condenser. You definitely don't have to remove the bumper or grille. The most difficulty I remember having was fighting with the dang fan shroud haha.

Oh, yeah. I forgot to mention you have to unscrew the two radiator mounting bolts.

I have a 2000 WJ Laredo with two fans (electric and water pump fans) because of towing package. It's a 4.0L engine.

If you have two fans (electric and water pump), it may be necessary for you to remove the bumper and grille. I have removed the radiator TWICE last month because I forgot to retighten the tranny line male fittings. Removing the bumper/grille isn't that hard, but it'll take you an extra time. Then pull up the A/C condenser (but DO NOT disconnect it). Then you push the radiator forward (toward you) and pull it up - to avoid electric fan hitting the water pump fan while removing the radiator. Don't forget to disconnect the tranny lines and upper/lower hoses before removing the radiator.

Hope it helps.

It's such a PITA to get the driver side lower bolt out, that I had the shop pull it out for me the last time it was in service, and just leave it in my cup holder.

I used a brand new radiator designed for a 4.7 and all you have to do is cut off two useless brackets with a hack saw and it slides right in. Ez upgrade.

Is that really all it takes? (besides disconnecting the mounting bolts)

I don't know why some people call it "hydraulic fan" but it isn't powered by hydraulic fan. I call it "water pump fan" because the fan blades are bolted directly to the water pump. The Jeep's service manual book calls it "viscous fan". I still don't get it when people call it "hydraulic fan".

I just googled "hydraulic fan". To my surprise, yes, those "hydraulic fan" do run by hydraulic fluid. Not many cars and trucks use them. I don't believe that our Jeeps with 4.0L engine have that kind of fan, only electric motor and/or water-pump driven fans.

Anyway, how many fans do you have (just count them between the radiator and the engine)? Mine has two - electric and water pump.

If you have only one fan, you're lucky. It'll be pretty easy for you to remove the radiator.

Good luck.

Well the reason I asked him was because he has the same fan with the same engine. I have the power steering pump driven "hydraulic" fan. Like most V8's.

But yeah I only have one fan. I was hoping to knock it out in a couple hours today. I parked in a parking lot and she was dripping from the corner of the radiator with no leaks above it.

The fan with lines coming off of the power steering pump is indeed hydraulic my friend. Got a better name for it? That doesn't change what it does.

Sorry everyone I hadn't been able to comment here lately. Been huntin jobs and finishin up my coal mining classes so I can get in the mines. Using the girlfriends car for all that haha

Anyways yes it is a 4.0. And the only fan that I have seen when I checked it out couple nights ago was the electric fan. My jeep didnt come with the tow package but it does have an aftermarket hitch and all from the u-haul. (Used to be a rental ride when it was first owned out of Georgia I think).

You figure after 4 owners before me, someone would have upgraded some cooling??? Also when I flushed the radiator out the other night there was mud and dirt and other crap inside of it. But surprisingly nothing came out of the block or anything which I thought was weird?

So after all the flushing and all and making sure the water was clear as day. I started to putting everything back on and thought it was just a hose. No big deal right?

But I do have a hole in it somewhere on the driver side so I will pull it out and run to the JY to get one if I can't patch it until I get a job

Btw what would the difference in the 4.7 one an the 4.0 be? I have a JY like 2 miles down the road that has a 4.7 wj and I could get that for free of anything!

There isn't really a temp fix, you can try using fillers on out side but they wont last.

dont waste your money on any stop leak products added to the coolant. They will cause more problems than they solve.


Best option is replace the radiator.
Also good opportunity to flush and refill the coolant system.

1ATony has radiator listed at $119 dollars including shipping.
