Hi everyone, I purchased a new 2004 Ram 2500 turbo diesel and here is my questions regarding the shutting of the engine. By reading the manual, it states that if not towing was done, you can shut the engine in less thatn a minute, and if light towing then a few minutes, and then heavy towing four minutes prior to shutting down the engine. That part of the manual I understand, but is when you normally drive with no towing, the manual states that if no towing with the truck, you do not have to wait more than a minute to shut down. That is okay also. But my question is when I shut down the engine after driving, and not towing, the engine appears to shake and even chirps when shutting down. I heard that is normal, other people said is because is a diesel engine, but it sounds so bad when shut down, and when driving sounds so nice. That is my concern, the shut down and chirping and shakes of th engine. Does any adjustment will make that chirping sound stop? Other than that, the truck is sweet, turbo is awesome.

 

The Chirp is the "V" belt up front and completely normal.

Shutdown: Normal driving..No wait time...

High speeds...wait a couple of minutes...especially if you come off a highway and immediately stop for fuel or rest stop...

Towing...same as high speeds

Or, switch to SYNTHETIC oil and not worry about it at all, unless your doing excessive towing...then invest in a cool-down timer.

 

With normal driving, like a 30 minute drive home from work for me, I let it idle for about 30 seconds to 1 minute and it's fine. It gets down to 300 degrees in that time frame and it gives me some time to get my crap together to bring back into the house.

The chirp is indeed your engine stopping faster than your belt and accessories and perfectly normal, not to worry.

 

"It gets down to 300 degrees"

I hope this is a typo or you're talking about EGT's.

 

This is only partially true. Synthetic oil might have a higher temp at which it cokes, but not an infinitely higher temp. It will still require a cooldown.

 

Sometimes in July/Aug/Sept it feels like that outside, lemmee tell ya!

Yup, it was the EGT's I was referring to.
