6.7 owners manual question, I have the 5.9
Hey there 6.7 owners. Can anyone tell me if the 6.7 owners manual states to use the Exhaust brake ONLY when towing? Not daily driving? I had a turbo replaced on my 5.9 under warranty and my new one is seeping just a tad. A very reputable dealer told me that I should only use the PAC BRAKE when I am towing... I just wondered if the 6.7manual said the same as both brakes operate in similar ways, Thanks!

the only thing similar about them is that they create exhaust back pressure against the motor. Otherwise you are talking about 2 completely different turbos, which is what this is about correct?
You are aware that the "exhaust brake" on the 6.7, is just the Variable geometry turbo closing correct? Just checking. |
Check with Pac Brake on your situation. I ran a BD brand brake for over a 100,000 miles, towing or not, and no problems.

copied and pasted from the owners manual of a 6.7
DIESEL EXHAUST BRAKE (ENGINE BRAKING) – IF EQUIPPED The exhaust brake feature will only function when the driver turns the exhaust brake switch to the ON position. Once the switch is in the ON position and the vehicle is moving faster than 5 mph (8 km/h); the exhaust brake will automatically operate when the driver removes pressure from the accelerator pedal. Exhaust braking is most effective when the engine RPM is higher. The automatic transmission has been programmed to downshift more aggressively when the exhaust brake is enabled to increase brake performance. Do not use the Exhaust Brake feature when driving in icy or slippery conditions as the increased engine braking can cause the rear wheels to slide and the vehicle to swing around with the possible loss of vehicle control, which may cause an accident possibly resulting in personal injury or death. NOTE: For optimum braking power it is recommended to use the Exhaust Brake while in Tow/Haul Mode. The purpose of the exhaust brake (engine braking) feature is to supply negative (braking) torque to the engine. Typically, the engine braking is used for, but not limited to, vehicle towing applications where vehicle braking can be achieved by the internal engine power, thereby sparing the mechanical brakes of the vehicle. Benefits of the exhaust brake are: ² vehicle driving control ² reduced brake fade ² longer brake life ² faster cab warm-up. The exhaust brake feature can also be used to reduce the engine warm up time. To use the exhaust brake as a warm-up device, the vehicle must be moving less than 5 mph (8 km/h), the exhaust brake switch must be in the ON position, and the coolant temperature must below 180°F (82°C) and ambient temperature below 60°F (16°C). |
I have used e brakes on all my trucks and engage it all the time, average mileage for brake work is over 120K + miles with fulltime use of e brake.
