I just joined this forum a short while ago and left an intro in the introduction section. I'd like to replace the (as far as I know) original radiator in my '05 Z71 5.3L to prevent future problems. 242,000 miles on the motor and it runs great, but the Tahoe is our back-up vehicle, not a daily driver. The previous owner, a good friend, performed a lot of work on this as he had meant to keep it but plans changed. I'll provide a list of what he performed. What are your recommendations for a new radiator?

The original (?) OEM radiator lasted for 242,000 miles, so why not replace it with the same radiator? You can get good reduced pricing at RockAuto.com and at GMPartsDirect.com.

20 years ago, things were manufactured to a higher standard, especially for brand new vehicles.
I HOPE OE for a 20 year old vehicle still means what it did 20 years ago, but I am not an optimist.
When you are doing maintenance replacements, it's ok to upgrade, if the price is right.

While you're there, very seriously consider replacing the rear HVAC coolant Y & T connectors.
Even if you feel froggy enough to not replace them in advance, buy them now, &
keep them in the glovebox for when they do fail.
