Jul 21st, 2025 | | | | Joined: Sep 2008 Posts: 289 'Bolter | | 'Bolter Joined: Sep 2008 Posts: 289 | On a Task Force 1/2-ton, were there different radiator locations depending on the engine (V8 or L6), like on the cars?
I am asking this because I am thinking of adding A/C to my truck: the Vintage Air online instructions show V8 and L6 radiator core supports, but the GM Factory Assembly Manual does not seem to show 2 locations...
My truck has a Camaro front clip and a 250ci L6 engine, but all the parts at the front look pretty stock to me (rad support, cover, panels on each side of the rad...).
Also, could someone give me the dimensions of the core of a stock rad? I think mine may not be as tall as stock...
Pictures of what a stock rad/support... looks like would be great too!
Thanks!

I've seen an assembly manual page of the V8 setup, but can't find it just now Bill | | | | | Joined: Sep 2008 Posts: 289 'Bolter | | 'Bolter Joined: Sep 2008 Posts: 289 | Thank you for the answer and those pics, very nice!
Good, so now I know I have the stock rad support and the rad in the L6 engine position.
My rad does not seem stock, though, the top of the tank is barely above the top bar of the rad support... It does look very OEM and fits well, but... Where there different rads available, maybe?
Anyone can give me the actual dimensions of the core of a stock rad, so I can make sure the A/C condenser from a kit would fit properly?
I like that fan shroud you showed, I may have to look for one! Or make one like it...

Thanks again!
