Radiator and Oil Pump Replacement

[Brent Martin]

New to Posting.

I have a 94 K1500 Burb with 180k just purchased with hiway miles back and forth from NC to FL. Truck still has loads of power but the oil gauge seems to float under 40 psi at idle. 1) should I even mess with changing the oil pump with this many miles since I plan on swapping the motor when it finally does go or would it be wise to be preventative (or does this just indicate that it is finally going) and 2) the top radiator hose was removed by Sears
to flush out dead antifreeze and upon getting the truck back I find that the plastic radiator casing is cracked and is leaking -- anyone know of what recourse I can expect if any and also what type of radiator to replace the existing one with -- I'd like to upgrade bc the truck is rust free and I plan on keeping her awhile. Thanks
