Cummins Thermostats

KLM Performance carries these OEM Cummins replacement thermostats

The Cummins thermostats are available for the following Cummins engines:

  • 3.9L Cummins diesel engines.
  • 5.9L 12 Valve Cummins diesel engines.
  • 5.9L 24 Valve Cummins diesel engines.
  • 6.7L Cummins diesel engines.

When it comes to selecting a replacement thermostat, KLM Performance recommends going with the OEM Cummins thermostat. Each Cummins Replacement Thermostat is built to the exacting standards required for a long and trouble-free diesel engine life.  For the safe and secure operation of your diesel engine, monitoring the entire engine cooling system is a smart practice. The cooling system is not the place to purchase a low-priced part. The purchase of an OEM Cummins Thermostat ensures optimum engine performance and fuel efficiency.

Cummins Replacement Thermostats are:

  • Designed for proper fitment and sealing.
  • Offer dependable long-term performance.
  • Ensure correct cooling system temperature ranges.
  • They are manufactured to the exacting standards required.

Warning signs you may have a problem thermostat in your Cummins diesel engine:

  • A reduction in fuel economy.
  • A decrease in overall engine performance.
  • Erratic engine operation temperatures.
  • Unexpected vehicle or component break down.

What are the benefits obtained by purchasing an OEM Cummins Thermostat? 

  • Genuine Cummins Parts are backed with a manufacturer's warranty.
  • Genuine Cummins Parts provide optimum engine efficiency and peak power levels you need to get the job done.
  • OEM Cummins parts provide the exact fit for a straightforward installation reducing your downtime.
  • Cummins parts ensure you're up and running for financial protection and peace of mind.

NOTE: Do not operate a diesel engine without a thermostat installed except for servicing or testing of the engine's cooling system. An engine with the thermostat removed will function in the radiator bypass mode. Without a thermostat installed, there is no way to regulate coolant temperatures which will cause an overheat condition resulting in severe damage to the engine. If you are now going to replace your engine's thermostat, this is the time to do a complete antifreeze change. We also recommend performing a comprehensive inspection of the cooling system water pump, hoses, and clamps.
