What this EGR valve cooler kit does
The exhaust gas recirculation circuit on a modern diesel feeds exhaust back into the intake to cut combustion temperatures, and the cooler and valve in that circuit are a known service point on the 6.6 L Duramax L5P. This kit supplies the plates, hoses and gaskets used to close the circuit off and reroute the coolant at service time, with fittings TIG welded for high temperature work.
Supplied under the Vidishi Auto brand, this unit is aimed at distributors, workshops and fleet buyers who need a repeatable, documented part.
Why choose this unit
- Sized for the 2017-2023 6.6 L Duramax L5P rather than a universal plate set
- Block-off plates cut to the L5P port layout for a sealed joint
- Bypass hoses reroute the coolant around the cooler at service time
- Fittings TIG welded for high temperature exhaust work
- Gasket set supplied so the joints can be made up with new seals
Compatibility & fitment
The kit is specified for the 2017 to 2023 6.6 L Duramax L5P in Chevrolet Silverado and GMC Sierra trucks. L5P is the 2017 onwards generation, so earlier LML and LGH engines take different plates, and the coolant hose routing has to match the truck’s build before the plates are fitted.
Confirm the engine generation is L5P (2017-2023) before ordering. Plates cut for the L5P will not seal on an LML engine, and emissions rules on deleted EGR circuits differ by region.
How it works
Closing the EGR circuit means blanking the exhaust feed into the intake and rerouting the coolant that used to pass through the cooler. The block-off plates seal the ports, the bypass hoses carry the coolant around the cooler, and the gaskets take up the casting irregularities so the joints stay tight as the engine heats and cools.
Installation steps
- Work on a cold engine and drain the coolant to below the EGR cooler level.
- Remove the EGR cooler and valve and clean the port faces.
- Fit the block-off plates with the new gaskets and torque evenly.
- Reroute the coolant with the bypass hoses, refill and bleed the circuit, then check for leaks.
Safety & certifications
Exhaust components stay hot long after the engine is stopped, so the work has to be done on a cold engine. Emissions equipment may not be legally removed or disabled in your region; check local rules before fitting, and the coolant circuit must be refilled and bled to the spec in the service manual.
Typical use cases
- L5P Duramax EGR cooler service
- Workshop rebuild of a 6.6 L Duramax intake side
- Fleet maintenance on 2017-2023 Silverado and Sierra diesels
- Preparing a truck for a cooler replacement where the circuit is being closed

How it compares
Against replacing the EGR cooler with another cooler, this kit closes the circuit instead, which removes the cooler and valve from the coolant and exhaust path. The trade-off is regulatory: where emissions rules apply, a service replacement cooler is the compliant route.
Troubleshooting
- Weep at a plate joint – the port face was not cleaned or the gasket was misaligned
- Coolant loss after the job – the circuit was not bled correctly
- Check engine light – the ECU still expects EGR flow on some builds
Maintenance
- Recheck the plate bolts after the first heat cycles.
- Watch the coolant level for the first week after fitting.
- Inspect the bypass hose clamps at each service interval.
