Product Description
FLEECE FPE-6.7CR-COOL-PLUG 6.7 CUMMINS STOCK VGT TURBO COOLANT DELETE PLUGS
When you replace the stock VGT turbo on your 6.7L Cummins with a non-water-cooled turbo, the factory coolant ports on the riser block and firewall can’t be left open. The FLEECE FPE-6.7CR-COOL-PLUG kit gives you a clean, leak-free way to cap those ports, simplify your under-hood plumbing, and keep coolant where it belongs.
Engineered by Fleece Performance Engineering specifically for the 6.7L Cummins platform, these coolant delete plugs are sized for a perfect OE-style fit and built to handle the heat and pressure of hard-working Ram 2500/3500 trucks. Whether you’re doing a performance turbo swap or cleaning up a custom build, this is the right hardware to button up the job.

Frequently Asked Questions
Do I need these plugs if I'm still running the stock water-cooled VGT turbo?No. The FPE-6.7CR-COOL-PLUG kit is intended for trucks converting from a water-cooled stock VGT turbo to a non-water-cooled turbocharger. If you're still on a factory water-cooled VGT, you should retain the OE coolant lines and hardware.
Will these coolant delete plugs cause overheating?
The plugs themselves don't change coolant flow through the engine—they only cap the original turbo coolant feed and return ports. As long as your new turbo and cooling system are set up correctly, engine coolant flow and temperature control remain normal. Many 2nd-gen swap and non-VGT setups use this style of delete hardware without any cooling issues.
Do I need to use thread sealant on the plugs?
Fleece recommends treating these like any other threaded coolant port. Follow the instructions included with the kit or your service manual—typically a quality, coolant-safe thread sealant is used to prevent seepage and aid removal later. Always avoid over-torquing and make sure the sealing surfaces are clean.
Which other Fleece parts pair well with this coolant delete kit?
If you're doing a turbo swap on a 6.7L Cummins, it's common to upgrade other cooling components at the same time. Popular combos include the Fleece M22 thermostat plug, heater core replacement hose, thermostat housing with auxiliary port, and the coolant bypass hose for 2007.5–2018 bypass kits—all of which are available from CPP Diesel in the Fleece Performance catalog.
Is this kit legal for use on emissions-controlled vehicles?
These coolant delete plugs are a hardware component used when changing turbocharger configurations. Any turbo swap or emissions-related modification must comply with local, state, and federal laws. Always verify the legality of your overall turbo setup (including tuning and emissions equipment) before driving on public roads.
