Radiators: what fits?

[rednine4]

So i've looked around but it seems like there is not a simple bolt in and go radiator.

What do you guys recommend, a flex fan and tucking the radiator under by cutting the core support.

or putting the radiator in with a pusher fan?


Not sure which radiator I should use either... any part #'s or ideas would be much appreciated

In my 93, I run the heavy duty, 2 core, 4.0 radiator. Cheap and readily available.

Mine is the stock 4.0 rad... Two little 10" fans. runs at about 160* or less... Maybe 180* in rush our stop and go traffic.
It was very simple to tuck underneath.

my brothers 95 ranger has a small radiator in it part number CU1722... it seems to fit well, but just visually I am not sure it will fit in my 85 BII 4x4 as it looks too tall. I didnt take any measurements but I am wondering is there any difference between radiators 4 wheel drive and 2 wheel drive and their mounting points being higher or lower?

Teddy that looks like a nice fit, did you get a remote radiator cap for that or is there enough clearance?

The 91-94 Explorer 4.0 auto A/C rad is a bolt in deal.

I am running the rad in the stock location with a 16" pusher, I had it idling outside the shop yesterday (80 degrees) and it never got above 190. That is where the thermostat opens and the fan kicks on.

It is on the trailer to go to the exhaust shop as I type, so real world testing hasn't taken place.

I'm using a universal 26x19 from Jegs. You have to really cut up the core support to make it fit. If you dont have a body lift it won't fit without making some room in the frame as well. This one is overkill for sure and you could use a smaller one but I have used it hard and never over heated.

early 90s explorer 4.0 radiator. bolt in if you have the short shaft water pump. i didnt so had to tuck it at the bottom of the core support. no chopping or anything just set the bottom of the radiator inside the core support instaed of on the brackets and made custom hold down brackets

I used Summit racing's smallest universal radiator in my most recent v8 swap. I started with a CU1721 but after a brand new one of those POS's separated at that tank after 15 minutes of running the first time out I went with a higher quality one. Another thing about the Cu1721-1722 is the lower hose barb is at a really stupid angle the makes finding an inlet hose that will work an interesting endeavor. Keep in mind if you go with an aftermarket one that you don't need and wont benefit much from anything wider than the opening in the radiator support. The small summit one I have is as big as you need to be, even that one has abut 5% of the core covered and both tanks are covered.

Edit:

On a side note - the jegs and summit radiators will take a little more work installing, but will work better, last longer and at about $155 shipped are a little cheaper than the factory style ones that work. This is the one I used http://i627.photobucket.com/albums/tt351/deranged57/Deranged V3/IMAG0016.jpg, I tucked it under the rad support, cut a hole to access the cap, and used rubber hoses sourced from junkyards to make the connections. I also added an inline filler since my upper hose ended up 2" above the rad. cap due to my march pulley set-up. I am using a low profile electric puller fan that I got from Ebay.

yeah......what he said

I used the radiator that came with the motor. I did not have fab any brackets or anything. Mine is a 05 though it may be different than yours.

If I click on this link i get a pic of a differential cover. LOL

I would like to see pics of your radiator setup though.

 

[rednine4]

Yeah i noticed the diff pic too lol..


I went to the parts store to get the 91-94 explorer radiator with A/C and Automatic... but there was a listing for an HD radiator and a standard one... which should I get so I can be sure it fits?

Not sure how I pulled that one off but here is the correct link. http://www.summitracing.com/parts/SUM-380424/

I can take pictures of my setup when I get home in the AM and post up tomorrow.

The HD will be a 2 core and the other just a single. Both should mount the same but the HD will be a little bit thicker.

SO Here's what fits, as of now I went and Got a 4.0L explorer radiator with automatic and A/C. A basically perfect fit into my 85' BII. For the hoses I used a 93 mustang GT upper and a flexable universal lower. Fits nicely.. when I fired it up I instantly saw a lea k coming from my heater core. Thankfully it's an easy fix on a BII

I will confirm the results of the cooling ability of this radiator once I install a fan.. probably going to have to be a front mounted electric due to clearance issues with the water pump being tight.

The built in transmission cooler is simply extra for those of us with manual transmissions. Although I think the built in transmission cooler would be too small and wouldn't flow high enough for engine oil - these could be potentially used as a power steering cooler if plumbed into the return side - this would also be great because we would drastically increase the volume of the system. Has anyone tried this in the past?
