coolant leak

[Polmanteer]

2007 5.9 3500 dually, noticed for first time stream of coolant coming from under truck apparently dripping from back of engine where engine and trans connect.
engine has a block heater and have had problems with leakage when heater is plugged in but that in cold weather and the temp today here is in the high 70s. Does anyone have an idea why it would suddenly start leaking while sitting and the truck hasnt mover for over 10 days.

There is a small coolant hose covered in foil that is behind and underneath the turbo on your truck. It WILL eventually leak and cause drips/loss noticeable right where you are seeing it near your bellhousing...there IS an updated hose AND clamp from Mopar and/or Cummins, but you will pay MUCH less for it from Cummins--

Here are the Mopar numbers for what you probably need, sorry do not have the Cummins part #'s right now, though someone else may chime in or you can find it with the google--


1-05179114AB hose
(2) 1-05179115AA clamps

The neighbor came down and asked me to give him a hand on his 06. He got the old hose off by cutting it but could not get the new one on. If you look at the photo of the new hose installed you can see a goober that is on the top pipe. It would not come off and kept the hose (that is very flexible) from pushing on far enough to get it over the lower pipe. Photos were an after thought, but removed inner fender, moved generator, front pipe hose lower clamp by oil filter, front pipe bolt to block, and turbo oil feed line to get front pipe to rear pipe gap larger. Sounds like a lot of work, but it really made it easier. Had that goober not been there it would have been a 10 minute job. Unfortunately he didn't get the spring clamps. If he had the job would have been tough without the good remote spring clamp pliers. The normal spring clamp pliers would be tough to get back there.

Top photo, 10mm bolt on front pipe. Second photo, same bolt and turbo oil feed line. Third photo goober on top pipe that kept hose from being slid all the way up. Last photo slide lower clamp up on blue hose so pipe can be removed.

The new line looks like it fits TIGHT. Does it easily expand over the pipe or is it a battle?

 

[seafish]

COuld you have easily ground or filed off the "goober" , or is it too tight access to consider that an option??

 

[sag2]

The new hose is very soft and flexible, nothing like a "normal" heater hose. Yes the photo makes it look easy, no access to get in there and knock or grind it off. I thought it might be a glob of paint, but it didn't budge with a screwdriver.

The new hose is a smaller id than the origional-yes it is a very snug fit

see that would bug the crap out of me with those clamps not being turned the same way. I'd have to take one off and flip it over.

LOL!!! Me too! That is too funny.

Wingate and Dave, I like to do things "purdy", too, but I like maneuvering room even better. Which are the best clamps to use now? The screw-tite or the spring?

for that line i would use the spring clamps so they self adjust....this job is way to hard to have to go back and adjust the clamps again....

That little piece of hose has been a pain in the butt for a lot of people many times over.

 

[sag2]

Actually he flipped them to make them easier to get to. The camera make it look easy.

I just allow mine to cold leak. Only time it leaks is during the colder winter months... even then its just a nuicance. Overflow bottle has to be topped off about once a year... Not worth messing with fixing it.
