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.
- Wiring Kit Information: This package makes the wiring of the fans a snap with special Molex connectors. Pics of electrical kit coming soon (better than what we have now for pics, sorry)

Great experience, order got messed up and Brian made sure to get it fixed and kept me up to date by texting me.

Exactly what I needed and had it next day

Customer service was great. Order shipped quick. Great value and the change to the car was better than expected. Wife no longer braces herself for the expansion joints and other Ohio road issues.

Brian was AWESOME to deal with, I changed my mind a few times on what I wanted to do with my c6z.. You can go down an endless rabbit hole when you get into these cars “while I’m in there “He was right there with updating pricing and I couldn’t ask for more.. Parts are parts and they will fail but it’s the service that sets the bar for a big purchase.. I haven’t driven the setup yet as it’s still being built but I’m sure he a phone call away to get it sorted..

Great customer service as always. Was on my doorstep within 48 hrs.

High quality parts with installation pics to come

Great support team helped me get the parts needed and got my order within the week.

Balancer was exactly what I needed. Everything as described and fast shipping. Thanks guys

Team went above and beyond to locate the part needed to get my can back on the road asap.

I finally got to install the intake which literally took 10 minutes. The power and launch difference was insane! You can hear the turbos spooling a lot better as well. I’m amazed by the difference just from the intake

Great product and communication.

I went with the super low, extended rear shocks , Swift 9/7k upgrade and absolutely love the stance and how the truck rides. It’s tight in the corners , smooth driving down the hwy and not bouncy at all. Thanks to Brian for getting me set up.

Completely changed my car

Everything seems in good condition and good quality, appreciate the help from brian for all my questions and to setup the shipping to canada

Hello, these coil overs are great. Very good quality and look great! Thank you!!
