Engine/Transmission (1998.5 - 2002) Jake Brake Operation

[dbothwell]

I recently had a Jake Brake installed on my 03 Ram 3500 6 speed. This is my first diesel so I'm still sorting some things out. This forum has been an invaluable aid.



My question is about operating the Jake Brake. The dealer that installed it said that I could leave it turned on all the time, which is essentially what I've been doing. It really helps slow things down when I get off the go pedal.



Is there any downside to leaving the exhaust brake activated all the time? It came with a switch mounted on the gear shift so turning it off and on is not too big a deal. Just seems more convenient to leave it turned on and it doesn't seem to be activated when I'm accelerating.



Thanks,

Dave,



Welcome to the TDR - invaluable aid as you said.



The exhaust brake is set up to operate only after you release the go pedal. I'll let the engine experts speak to the long term durability and other issues about using it. I do leave mine on quite a bit, but I will warn you about using it in the rain or snow - the truck can try to swap ends if you're not paying attention!



Still one of the best accessories for my money - enjoy!

Exhaust brake...

I just installed a Pac and the operation of both is nearly identical. I cannot imagine always leaving the unit on. Sitting at a stoplight and having the butterfly closed on the exhaust would drive me nuts, not to mention that it would sound like you have a potato stuffed in the tailpipe. Listen to the way the "Big Boys" (semi's) use theirs (and engine brakes), they always release the unit just before thay come to a stop and let them idle unobstructed. The other thing... that is why the switch is so convenient... so it can be switched. IMHO much of the information that dealers and service depts. freely share, is not much better than what you get from the neighbor or your brother-in -law... if you know what I mean... Don't take it as gospel... ask lots of questions...

i'm surprised that they didn't put a clutch switch on these like they do on the bigger trucks.
