ECP 1997 - 2004 Corvette C5 Aluminum Radiator - 6 Speed Manual - Engineered Cooling Products
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.
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.
Purchased the ECP Radiator for my C5 Z06, haven’t installed it yet but I can say this is one of the best looking radiators I’ve seen in a long time, weld quality and attention to details is amazing. I’m excited to get this radiator installed!
Thanks Brian for a great product!!
Awesome job with any questions I had with my installs or what I should do next. Always answers the phone. Fast shipping
Awesome fits almost perfectly and works amazing shipping was on point no damage and really appreciated the quality .
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
Let customers speak for us
from 187 reviewsHad a lot of drivetrain flop in the C5 I picked up. Ordered these as I was doing long tubes and they would be easy to access. Massive improvement over stock and hardly any increase in NHV. Now no more drivetrain flop and significantly reduced wheel hop. Will be doing the AMT diff mount next.

This was my second purchase from FIPERFORMANCE and I must say I appreciate the fast shipping and notifications of order status. I installed this yesterday and it was pretty straightforward but the video and instructions explain the process well. I habe the AMT motor mounts too and so far I don't feel any increased NVH. The rearend feels tighter (havent tried launching yet) but I don't know if its just me but the shifting seems smoother too. I have an MGW with 2 washer venom mod and it felt good before but it seems its more positive now but not rachety. Overall awesome piece of well made equipment. Thanks again
Communication was great and shipping was lightning fast!
Every time I order anything from Brian he goes above and beyond! You aren't just buying parts from him you are buying a great experience with someone who understands customer service! The alternator was perfect and was installed with zero issues. My car had zero issues with the battery warrning indicator after the install which is typical with tge c5.

I was able to install these in a day and am very happy with the results. Ride is even smoother than the factory F55 mag ride. Handling is unbelievable with sticky 200tw tires. Love the adjustable height and damping. Brian was great answering my questions. I am completely satisfied with this purchase. It is a true upgrade from the stock suspension, no placebo effect here.
I ordered a set of Silver's Neomax coilovers for my C5 Z06. The order shipped out quickly and I received emails from Brian every step of the way to include tracking information which was very appreciative. I also received an in-depth installation guide and Brian even followed up with a text message to confirm everything went well so the customer service has been outstanding to say the least. I have not installed the items yet as I'm waiting for a few other things to come in but so far they appear to be top-notch and I'm looking forward to having them installed. I will definitely be ordering additional products through FI Performance based upon my experience with this order. Again thank you Brian very much!
I love the radiator. Big improvement temperature around 185
Shipped as promised, on time..
Very helpful and the tuner works awesome
Brian has a ton of knowledge and very informative. He was able to set me up on the right coilover and spring tensions for my exact build. Fast shipping and quick replies
I’ve only received my diff brace still waiting for my trans brace only got one tracking number so not too sure about that
