– All aluminum construction with a heavy duty 2-row core with 1.0″ tubes with a high density core that has a higher density core than other high performance radiators costing 3 times as much!

– Heavy duty transmission cooler for automatic applications

– Fully TIG welded construction with no epoxy.

– Upper hose and lower connection is 1-5/16″.

– Overall dimensions are 28″ wide x 18-7/8″ tall. Core is 24-3/4″ wide x 17-3/8″ high.

ELECTRODE Kit Information:

Engineered Cooling Products Consumable Electrode Kit V2 - The Radiator Savior

The number one thing that is likely to destroy your radiator is electrolysis. When the engine grounds or PCM grounds are old, weak or break, the engine coolant becomes a ground path. In modern builds with LSX or EFI swaps, this can be a major problem. Especially when using an OEM wiring harness that has been cut up or butchered for a swap or Corvette C5's which are "ground" Nightmares.

Vehicles at significant risk of electrolysis are corvettes, s-10 swaps, 4th gen fbodies, any EFI swap and most LSX swaps.

Other culprits include cheap Home Depot crimp connectors that are not made for automotive use. They look great when you install them, but check on them 6 months later. Especially the super cheap ones made from vinyl.

Any vehicle with ratchet old wiring is especially at risk of electrolysis. This is bad news. When too much electrical current ends up in the radiator, it’s a grim prognosis for your radiator. It’s actually a death warrant for your radiator, it’s a just matter of time until it starts leaking.

Much like the anodizing process with aluminum, when you have current flowing through the radiator, it puts the corrosion process on steroids and destroys the brazed tube-to-header joint on the radiator. There is no saving the radiator once this happens.

This electrode kit will substantially help reduce the effects of electrolysis by concentrating the current flow on the zinc anode rather than the radiator. After lots of testing, our new version has a tapped port for grounding the anode to the chassis. So the consumable electrode gets destroyed rather than your shiny new radiator.

Includes the anode, wiring, crimp connectors and instruction manual. Has 1/4″ NPT thread and works in place of most drain cocks.

Perfect fitment and even better cooling

Picked this up because my stock radiator had a hairline crack on the end tank. A lot of the older posts on Facebook said fitment wasnt great but I figure at less than half the price of the D brand I'd risk it. Fitment was absolutely perfect. The condenser and fans slid right into place better than OEM. Quality and welds are on par with the Koyo Radiators I have in other cars that cost significantly more.

Radiator keeps the car much much cooler than the stock unit. Hardly ever seeing higher than 210F unless Im in heavy traffic and higher ambient temps.

10/10 would absolutely recommend this to anyone needing a new radiator or looking for an upgrade.
