John Deere’s 6430 is a 4-cylinder 8-valve 4.5L running Tier 3 emissions controls which includes an EGR valve.

The 6430’s EGR valves can become blocked with carbon build up. The EGR system is also water cooled and this system can leak, repairs can be costly.

Benefits of removing a EGR valve on a John Deere 6430.

  • Lower engine intake temperatures
  • Lower combustion temperatures
  • No EGR cooler to fail
  • No EGR valve to fail and cause down time

Here at Alt Tune we can command the EGR valve shut and also remove the function from the Phoenix L14 or L15 ecu that controls the engine.

Example codes we can resolve.
