If you’ve tried to do any type of towing with your truck, or low speed off-roading, then you probably already know how wussy the stock radiator is in these trucks. Especially in the V8 H3 trucks. It’s a 1-row with either 1″ tube or 32mm tube, depending on which engine combo you have. 

Upgrading your truck is straight forward with our drop in unit that doesn’t need the side OEM mounting brackets. Most of the aftermarket radiators for these trucks don’t include the side brackets, you need to recycle the brackets from your OEM radiator. Which is a problem, because they used three different versions of the brackets over those years.


– 2-rows of 1″ cooling tubes

– Cooling power up to 700HP

– Dual 11″ HPX aluminum fans for a total 3000 CFM

– Precision TIG welded construction

– Lifetime warranty

– Billet CNC machined filler neck

– Stainless steel hardware

Like all of our radiators, it’s made in the USA. We guarantee you’ll think it’s 7000% BAD ASS and guarantee it to cool your truck with ease. And of course our lifetime warranty on everything: radiator and fans. 

For fan control, use our RH-02 wiring harness.

    High quality construction. Barely fits into a factory V8 Chevrolet Colorado. Works absolutely great as designed at this time. They were also kind enough to weld an extra threaded hole into the lower radiator tank for temp switch. Absolutely perfect.
    -Fans were not positioned the same as in photo. Driver’s side is positioned lower and passenger side is positioned higher. Both are not equal height as photo represents. This unfortately caused me to have to shave some of the passenger side fan shrouding for the water pump threaded snout. It does nothing negative to the fan and doesn’t reduce structural integrity, but not the most ideal to have to do this. However, that’s how aftermarket stuff is.
    -Next thing, their radiator cap is quite tight on the neck. The tabs are either too large or the machined aluminum neck is slightly too fat. May need to trim the ears on the cap slightly with a file. No biggy.
    -Radiator hoses. Very tight on inlet/outlet necks of radiator. Takes some oomph to get them on there.
    Those are the only cons. Quite minor and doable. Upgrading/modifying away from OE REQUIRES SOME TOUCHES FOR FITMENT. That is truth for ANYTHING. I do NOT blame Entropy.
    Also, for those installing with factory A/C, remove the upper included ears on the radiator after marking holes for the condenser, drill holes, reinstall ears and secure the condenser to radiator with bolts at the top. Its not ideal to leave it flopping about.
