The Complete Coolant Valley Kit removes the EGR cooler, swaps every factory plastic coolant part for 6061-T6 billet, and replaces every valley hose with OAT-compatible silicone. One box. One install.
Off-road use only. Requires an EGR delete tune; we recommend Tunezilla.

Why your valley leaks
The coolant fittings in the valley spend their whole life baked by heat and soaked in hot coolant. Eventually they harden, crack, swell or start seeping somewhere you can't see, and you're tearing the intake off again.

Every plastic billet failure point. Replaced. Once.
Choose your path
Both paths get the plastic out of your valley. Pick the one that matches your build.
Smog safe · keeps your EGRKeep the EGR and emissions intact. Just swap the failure-prone plastic for billet that drops into the factory spot.
Off-road · tune requiredStop the engine feeding itself soot. Less carbon in the intake, fewer buried parts, and no plastic left in the coolant path.
Complete the job
After a decade of heat cycles, most seals come out hard and flat. They cost little to replace. The labour to get back in there doesn't.

From the garage
The kit was excellent and exceeded my expectations. It included everything needed for the installation, The manuals are also super easy to follow. The components all felt very high quality, fit properly, and the installation went smoothly. Most importantly, it completely solved the coolant leak I was dealing with. Everything has been working perfectly since the repair, over 6000 miles on it. This is a very complete, well-made kit and I would definitely recommend it to anyone dealing with the same issue. I recommend adding on the seal kit if you order this, as most seals will be hard and flat once you take things apart.

For EGR delete parts, yes. The EGR has to be turned off in software or the ECU will throw a check-engine light. We recommend Tunezilla, but any reputable tuner can do it. Parts marked Smog Safe keep your EGR in place, and require no tune.
About 2.5 hours for the OE intermediate flange and about 3.5 hours for the complete valley kit. The install manuals walk you through every step.
