Re: GMC 4000...? or 5000 series....Pictures...it's about time...
Here's a couple from the engine bay....
Check out the Copper tank on the Harrisson Radiator....This conventional configuration takes fourty quarts of coolant and like the other Vee-sixes....pumps about 120 gallons per minute at rated rpm....
I hav'nt cleaned her up ....only changed the heater hoses..
But that's fairly unmolsted...
