As far as fitting the 22" unit in your car, that's not an issue and the trans lines should match up pretty close. Our radiator is deeper than yours so the trans lines have to get pushed back a bit. That might require putting an extra 's' bend to create some space.does a MOP753A will fit in my 1965 300 838 2 barrels? I have no problem to cut/fit from my 22'' to 26'' just want to know if it will be hard to fit trans line?
This topic is pretty old. In re-reading, I don't see anything mentioned about a taller core. I'm also not sure 65polara ever supplied us with that sample. Members have been using both our 22" and 26" rads for the C-body. We just haven't figured out the 22" oem shroud fitment yet.
Good show then! Yes, DO combine the 18 inch core of the MOP751A with the tanks of the MOP753A and you WILL have a REAL WINNER for mid-60s C-body MoPars! I chose the 753A because it was the CLOSEST of your product line to my needs, but I expect a bit of added volume and surface area will only IMPROVE performance!
I can measure my old fan shroud brackets for you if it will help you design new methods for attaching the original shrouds to your radiators. I KNOW some of the other conservative hold-outs on this forum would LOVE to see somebody in modern industry tackle this exact problem. I can also measure how the nuts were placed on my 2524984 radiator. Mind you, THOSE DON'T fit the shroud brackets I obtained, but it still would be useful data I think.
About half way through post #1 Gerald mentions the core is about 2 1/2 " shorter than original, and on post #3 makes a suggestion that sounds pretty easy to incorporate. My 65 big block car came from the factory with a 22" radiator, and now has a warmed over engine. The extra capacity sure wouldn't hurt in the Florida heat.
My radiator now is from another company and has 2- 1" rows. The temps creep up when it is hot out.
If you are ok with the inlet being in a different position, I think that's the way to go. I really think all you need is that extra volume. We'll all be anxious to hear the results.Thanks Gerald for the explanation, the MOP751K (without trans cooler) sounds like it will be what I'm going to pursue.
My car has an 8 blade clutch fan and shroud with the Hayden 2797 I swap on and off for and an electric 16" Spal puller fan. Surprisingly, there is no difference I can see in idle cooling airflow. The issue my car has is coming from a fast cruise to a stoplight. It will be at 180 right on the stat until the point it has to stop and idle. Then the temp creeps up to 190 or so. Then you hit another stop light, now its up to 200 or over. Then on a steady light throttle run of say about 4-5 miles, the temp comes down to 190.
Hopefully the extra 25% capacity of the MOP751K will do the trick.
@Ccas Do you have any suggestions before I order? I can call your guys, just like to keep the board informed.
Thanks again Gerald for such an in-depth review.
Excellent write up By Gerald Morris, this is the information that I have been looking for.
The radiator in my 64' Dodge custom 880(Chryslers forward look design car) has started leaking from every orifice possible.
Texas summer's are just brutal on the radiator, creeping up on 205* in Dallas traffic.
(Few days ago the outside temp hit 110F*)
I have perused the Cold case website but seems like there is no update on a direct drop in install radiator, only choice to go with is a MOP753A, I would have gone with the MOP751A but I have A/C, so if I attempted to install the MOP751A the centrally located upper hose would bump into the A/C compressor low/high side Schrader valve.
See below for the photo and reference off of the MOP751A, and see why this would not work.
Hoping Cold case will accommodate an 18 inch tall & 22 inch wide core with the correct offset upper hose inlet as Gerald Morris has mentioned.
I was concerned on the aspect of electrolysis. Seems like my fears have come to light if the radiator dissolved in 16 months.Hail and Well Met, Sir Dodgealot! Huzzah!
Alas, Cold Case won't help you or me for a fewmet in this, BUT, Good Tidings yet come:
22″ Mopar BIG BLOCK HD Aluminum Radiator
Frank Son of Wat actually makes HIS aluminum radiators in ye Chicago! He makes a BETTER radiator than Cold Case, which I ran with perfect satisfaction until that evil **** destroyed it in her attempt at insurance fraud. The Cold Case Mop753A cooled well enough until it dissolved after 16 months. I was informed this occurs more readily with chinese aluminum, which is poorly refined and thus more susceptible to electrolysis.
Yes, the radiator I linked to from ECP is the excellent one I used. MUCH BETTER PRODUCT than that Cold Case as it turned out. Hands full just now. More later....I was concerned on the aspect of electrolysis. Seems like my fears have come to light if the radiator dissolved in 16 months.
Apologies on the insurance fraud you went through, never wish that upon anyone.
Also appreciate the link to the ECP (Engineered cooling products)
Hope business in Chicago is still going strong, heard there's quite a stir with looters breaking windows of shops and things getting stolen.
Honestly business around even in Texas feels non-existent, First radiator shop I went to wouldn't even attempt at a re-core of the original radiator, promptly was told the radiator is 'unsavable' I suspect he didn't want to mess with it.
Question: is the radiator in the ECP website the one you are using or have used before?
