Vehicle Fitment

Always verify with your engine serial number (ESN) for best results.

  • Ram 2500/3500/4500/5500 with 6.7L Cummins (ISB), 2007.5–2018
Important fitment note: Ram 6.7L models 2007.5–2009 and 2013–2018 use a 190°F thermostat (Cummins 5292712 → 5627589). Model years 2010–2012 typically use a 200°F thermostat (Mopar 68067109AB). If your truck is 2010–2012, confirm which temperature your calibration requires before ordering.

Installation Notes

  • Drain coolant to below thermostat level; clean housing and mating surfaces thoroughly.
  • Replace the housing seal (Cummins 3954829) when installing.
  • Torque fasteners per the Cummins service manual; refill and bleed the cooling system.

FAQ

Does this thermostat include the O-ring/seal?
Interstate-McBee M-5292712 is the thermostat only. Order the housing seal Cummins 3954829 separately.
Will it fit my 2010–2012 6.7L Ram?
Many 2010–2012 trucks were calibrated for a 200°F thermostat (Mopar 68067109AB). Verify before purchase if you’re in those model years.
What’s the OEM supersession for 5292712?
Cummins superseded 5292712 to 5627589 (190°F kit). Interstate-McBee M-5292712 is an OEM-style aftermarket alternative.
Will switching from 200° to 190° affect drivability?
Staying with the factory-specified temperature for your year is recommended. Changing temp can affect warm-up, HVAC output, and fan strategy.
