1982 C/K 6.0L Caitlyn Mall Crawler (Interior time)

Think I figured out the issue, I bought a piece of glass today after work, it’s the thicker glass vs the thinner. Still does it so I started messing with it and found that the aftermarket regulator was moving. So the nut was a little weird and I tried to swap it with the drivers side and it snapped off…

Guess what, now the drivers side falls out of the track with the missing nut.

Wasn’t a good day at work, drove it like a pissed off teenager. Or a drag week entry…. But I did park it on the side of the house with two windows up….

Well on the quest of getting this thing to run cooler for long trips I have decided to Duramax swap it...























Putting a Duramax radiator in, my thinking was it's a lot more capacity then the big block radiator and I can run the trans through it, and get a expansion tank as well.

 

[Babaganoosh]

Considering what it is, it fits good.

 

[Chevy305]

Is it getting hot going down the road or while at low speeds?

What's your fan setup like?

Also it's a good idea to fill the gaps in front around the radiator between the core support so to force all air in the grill area to go through the radiator. Foam or strips of rubber work well for that.

It gets to about 212 in Moab, blimp of the throttle to spin the water pump it drops to 194. The big thing I’m after is running the trans through it, that gets to 220 is during the summer months.

Radiators heat trans fluid more than cool it. Radiator in the loop mine ran 200, with just a standalone trans cooler 175-180

You gotta remember he also lives in hell where it's 120 the majority of the year.

it’s the thicker glass vs the thinner.

are the doors original to the truck? I remember reading somewhere that 73-80 have thicker size and later models have the thinner size.

My time in Moab this year, 700r4 got to 190 on Chicken Corners, also the hottest, the radiator went went to middle of factory gauge. I turned the ac off and it went down.
I am still running totally separate trans cooler. It is a large cooler with it's own fan.
I suspect the old temp gauge was lying to me, this new one sits around 160 most of the time. Had one 200 long up hill 3rd gear pull, unlocked torque converter, on I 70 going to St George.

They are not, I have aftermarket regulators that are causing issues.

 

[ZooMad75]

It’s odd. My 6.2/big block radiator with factory shroud and mechanical fan/clutch only sees 210 when it’s over 100 outside and I’m roaming the desert in low gear putting around. I’ve never once seen it over 210 and that’s going off the temp sensor for the pcm that I watch via scan tool data. The gauge in the dash runs midway most of the time but I don’t use that as accurate.

 

[Babaganoosh]

It’s more for the trans on a long run, it runs warmer then I want to. The engine is just a quick wack of the throttle and it’s good to go.

 

[Babaganoosh]

I think this should work.

 

[Wes Harden]

donno there looks to be a healthy gap between fan shroud and radiator core. should be as close as possible. That is a huge radiator thou

It looks much bigger in the picture.

 

[6872xtc]

I think that Wes is correct about the size of the gap. But, try it and see what happens.

How do you fill the system? Inline fill cap yet to be installed?
Are ya going to need an adapter for the upper hose?

I will be using a factory coolant tank for a 05, hoses not sure going to dig into what is on the shelf.

 

[Babaganoosh]

When I get home I’ll measure the distance, you guys are right but I don’t remember it’s that bad.

I was always told to seal it as best as possible. A 1/16" gap all the way around is pretty good, but the surface area still adds up. I have seen a few foam or rubber seals on some vehicles that had restricted airflow through the nose.
If you added up the surface area of a 1/8" strip, say 68" long, (34" core, nevermind the vertical) how much of an air leak could be possible?
Just food for thought.

I do know it fits closer to the bottom but towards the top it leans back.
