Yeah but I think if I recall correctly that because my engine's an 81 my rad hose comes out from the other side (to the left looking at the truck) and I'd have to change my t-stat housing to put a newer rad on?? (At least a landcruiser one)

In any case I should flush the coolant I guess and replace it. Is there any special tricks or advice to cleaning out the cooling system? All my stuff is old and was never "restored" during the engine swap like most people do.
