EDIT- post #34 in the link write up gives the sizes. !!!
Sorry I do not recall the screw sizes. I took one in with me and the guys gave me the next size up. It is a fastener store where I usually end up over paying since they have a $5 minimum and I am usually looking for just a couple screws or nuts.
Here is the write up https://dodgeforum.com/forum/1st-gen...ow-trim-3.html I haven't reread it but I know you have to drop the window to the bottom to get at the beltline screw closest to the lock. Could be the one next to it as well.I put a six inch piece of 2x4 in the bottom of the door to hold the glass up and make it easier to pick back up.

 

Thanks for the size!

I'll be tackling THAT this weekend.

Update: Had to replace the radiator. Spectra CU982 was $104 on Amazon, so another Extreme Cooling radiator in; this one, alas, is plastic tanked top and bottom.

Fits like socks on a rooster!

Also got the heater core connected back up; I bet I've got all the leaks out now.

Hey Ralph,

I purchased that same radiator about a month ago, but like many of my projects, they are taking forever to get done......

FWIW one thing I like about that radiator, the lower hose connection is set up for 2 different sizes of hose. That will make using a magnum engine easier......

I do have a question for you, Do you have a shroud to fit that radiator? If not, do you think the fan will move enough air without it? Just wanting to pick your brain on this.

 

I found a truck in a boneyard and grabbed the shroud; I WAS using an all metal CU982/Extreme Cooling equivelent, but that's the one that sprung a leak at a tank seam.

THAT radiator is back in the box and on the back porch to rebuild and put into storage later.

As to "will it move enough air" - I dunno; we have 105F days here, so I wanted the shroud.

It's missing the top door, so it's not as effective as it could be; but I never overheated, so it's effective enough.

I'll keep my eyes open and see if I can find another shroud to fit.

I'd shroud it if possible. Also, the filler on either side is different.

(I did cheat a bit ... my transmission goes through a dedicated cooler, not the radiator's transmission cooler.)

A few years back, I purchased an intrepid fan assembly.
I had hoped to sandwich it between the condenser and the radiator. However it is too thick, and giving up AC is just not an option I want to consider....
I may end up installing it behind the radiator for now....
But latter, I really want to use 2 fans, sandwiched between, like the shelby dakota did.
I really want a 5.9 magnum in this truck!!

Not sure what your opinion is on electric fans....
I would hope it would help AC work better in stop and go traffic....
And of course with a V8 and the 87-90 front end. I dont believe there is any other option.

Here is a picture of what I have.

 

Any idea how much air those will move?

 

Not Really, On the internet, some are claiming 3,000 cfm on low.... But again, you know how accurate post can be!!

I do know, member ragged89 is using them in a way that they are not designed....
He has a 89 dakota, with a 318 magnum engine.
He mounted the fans in front of the radiator where the condenser used to set.
He is using it as a pusher setup.
From what I remember, low, even in this way mounted, is keeping his engine cool.

One other point that may be of interest....
These are 2 speed fans
You activate 1 wire, and both fans run in low.
Activate the 2nd wire, (both wires activated at same time) and this gives you high...
It does not seem to matter which wire is low....
My thoughts are to use a temp. sensor to bring on one wire, and the ac to bring on the other.
In the event the engine needs the fan and ac is calling I will have high.
Just my thoughts.....

 

I like the idea, but, I would expand it a bit more. One wire, temp controlled only, for low speed. Second wire, tied to the A/C relay, so fans run on high with a/c on, and ALSO tied in to a second, higher temp, temp sensor. (I don't run my a/c all the time, and sometimes, the added cooling, without the need for a/c to be running, is helpful.)

 

I'd highly recommend upgrading the electrical (biggest alternator, bigger wiring, proper fusible link, 2ga battery wiring, etc.) then using a PWM fan controller.

It's in my long term plans; but not quite yet.

For now, I'm sticking with the clutch fan here. Last summer I never got past the 11 O'Clock position on the temp gauge.
