This is our HD aluminum radiator for the 1997 – 2004 C5 Corvette with a 6 speed manual transmission and 1997 – 2000 Corvettes with automatic transmission. This will not fit the 2001 – 2004 Corvettes that use the quick disconnect transmission cooler line fittings. This radiator features:

– 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.

ECP Radiator for c5 Z06

i just unboxed the radiator and it was shipped / packaged with care. The radiator seems very well made / great quality and craftsman ship. I still have to install it and will update the review once done

Looks great, but fitment needs to be better

The tabs that hold the shroud and condenser on the bottom of the radiator are too narrow by 1/16” and do not allow those items to slide in like designed. They need to widen the inside tabs by 1/16” and it would be great (or make the weld for the inside tab towards the outside of the car; as it stands now the condenser is hitting the weld), but at this time my AC condenser does not slide in the tabs and will have to be zip tied on the bottom. The shroud fits after some persuasion, but it’s plastic so it was able to bend a little.

Jeff - Thanks for the feedback and working through this with us. The data you supplied did uncover an issue that we have addressed and have pulled several rads. It looks like the radiator was about 1/2' thicker than normal and this could have adverse effects on installation. We/ECP has dispatched a replacement with a call tag. This has been addressed internally on ECP side and we appreciate your confidence.
