Product Details

The Mishimoto MMRAD-CK-78X is a high-performance aluminum radiator engineered specifically for 1978-1986 Chevrolet and GMC C/K series trucks. This direct-fit replacement radiator features a 19-inch 3-row brazed aluminum core that dramatically increases cooling capacity and heat dissipation compared to the factory radiator, making it ideal for stock, towing, or modified applications.

Key Features:

  • 3-row brazed aluminum core construction for maximum cooling efficiency
  • 19-inch core width provides increased coolant capacity
  • All-aluminum construction with durable TIG-welded end tanks for strength and reliability
  • Billet aluminum fill neck for premium appearance and durability
  • Magnetic drain plug captures metallic debris and fragments from the cooling system
  • Direct bolt-in fitment for easy installation
  • Backed by Mishimoto's Lifetime Warranty

This radiator upgrade delivers superior heat dissipation to keep your C/K truck running cool under demanding conditions, whether you're towing heavy loads, running performance upgrades, or simply want reliable daily driver cooling. The lightweight aluminum construction reduces weight while the precision TIG-welded tanks ensure leak-free performance for years to come.

Great price, great service, A+

Fast and easy with Amazon log in

Best price

Fast and easy!

I chose Autoplicity because they offered the best price on a specific part/tool I was looking for. Even with shipping cost, the total came out to below other online retailers (Amazon, etc.). My product shipped within the day and I am eagerly awaiting it!

Best Price and fast shipping, not bad price for the shipping cost

Excellent, easy, fast.

Great service, and prompt delivery. I would order again and recommend them to my friends.

Fast

Autoplicity had the best price on the Motive brake bleeder I needed, and they shipped quickly.

I got the items exactly as described with VERY fast shipping. i highly recommend them to everyone. And I will definitely be shopping there again!

Best price I could find on Moog Suspension parts.

tried to order a gasket with my exhaust pipe, shipping jumped12 just for gasket!! Not happening!!

This site had the lowest pricing out of any website that was advertising the same product on Google shopping. The shipping cost was very resonable and the parts arrived in two days.
