    My '90 K5 is ready for a new radiator.........the original one is both rusty on the outside and pretty clogged up on the inside, including a few pin-hole leaks, so I don't think it can be saved by the radiator shop.

    Here is what I've found so far:

    radiator.com - 34"x19"x2" 3 core (the OEM one is 4 core!) for $354

    Autozone - 4 core (didn't list any other specs) $348 + tax

    Advance Auto - 34 x 19 1/4 x 2 5/8 4 core (Transpro brand) for $348 + tax

    Napa - $472.......yikes.........

    I'm calling some local radiator shops this afternoon.

    I thought so also.........was hoping they would be at least a little cheaper than the local places.

    The IR4095 from AutoZone is made in Mexico. I asked for a rad for a 6.5 3/4T Sub and this is the one I got. $348. It fit in my K5 just fine where the gas rad was. The diesel rad is a lot wider than the gas model, and the brackets move over to the next set of holes. I punched some holes in the gas sheet metal for air flow, otherwise some of the rad is blocked. It has a built in engine oil cooler on one end, and the ATF cooler is on the other end.
