The GMC CCKW

I have a 1942 CCW that I am starting to disassemble. I pulled the radiator and took it in to get tested. They informed me that it will need a new core, are there any sources for a new radiator or is it best to just get this one re-cored? Also I am removing all the bolts and bagging and labeling them. Is it best to just replace all the bolts on assembly? I live where rust and corrosion has done a number on all of the bolts, nuts, screws, etc. The last question is the fuel tank needs some repair, has anyone had any experience with the Renu tank procedure?
Thanks for any information.

Hi Nick,

I'm not sure what the situation is like in the USA but generally good used or NOS radiators are hard to find,at least with getting yours re-cored you know it's going to be OK.

As for the bolts etc,if you have the originals with the AA and PA head markings I'd reccomend that you keep them if they are anywhere near useable,I've spent ages buying original bolts from junked trucks to replace the incorrect post war ones on mine.

If you plan to own it for a while, you will have to take it apart again....

Unless the bolt is special, I usually replace them all with new and add some never-sieze to them. If you were lucky enough to get it apart...

Hi Nick,
Kevin Kronlund armycarsusa. has radiators for sale you may want to compare the price as opposed to recoring yours.
He also has fuel tanks avail. again compare the two options then decide.
Hope this helps.

If this truck has been sitting for quite some time you need ti spend some special attention to the fuel tank. Rust can accumulate and cause problems in the fuel system. It is the very fine rust that is hard to filter out and will give you problems with the carburator when it gets in the jets.

If the Nuts and bolts are serviceable then reuse them, I drop them in a container of degreaser to remove any oil then into a container of Brick acid to remove all traces of rust ,they'll come up like new.Then you need to make a small amount of Caustic soda solution to neutralise the Acid and remove any paint wash with clean water and dry , finally soak in light oil over night. You'll have new original Nuts and bolts.

As for the Rad a Recore is always best ,you know you've got a tested Radiator which will do the job without a problem.

I agree with Chappers on the re-core. That cooling system is vital to the engine and it is better to know that the radiator will not fail on you.
I tried to save every original bolt on my truck, those that were not twisted off of course. I soaked them in diesel fuel in a large coffee can, and every once in a while, on a rainy day with nothing else to do, I would use the wire brush on my grinder to clean them up. What I got was a rust free bolt that still had the patina of 60 years of use. I found an F marked bolt holding the voltage regulator to the firewall.
