FAQ
Will this kit fit both 07.5–12 and 13–18 6.7L Cummins?Yes. 2GT101 is specified for 2007.5 through 2018 Ram trucks equipped with the 6.7L Cummins.
Can I use it with the engine hot?No. Perform pressure tests on a cold system to avoid injury and to get accurate results.
What pressure should I apply?Use the pressure specified in your service manual (typically around the radiator cap rating). Do not exceed the cap rating.
What if pressure drops but I don’t see a leak?Inspect heater core, water pump weep hole, turbo coolant lines, and hose joints. Dye and UV light can help spot small leaks.
