Cummins ISC Diesel Engine Aftertreatment Code Repair

There’s quite a back story behind this Cummins diesel engine repair.

This particular school bus had to be towed in because it quit on the road an hour out of town.

Cummins Code 2636 VGT Actuator

This Cummins ISB diesel engine was running flawlessly for years. It’s a 2009 so seven years with a fairly decent service record is a bonus for the fleet.

I can tell you this…… Continue reading Cummins Code 2636 VGT Actuator
