air cooler hoses

[ET]

I'm having trouble keeping my air hoses connected on the turbo side of the motor. I know that the booste preasure is higher on that side of the aftercooler. I only have this trouble while towing my camper. Any sugestions would be helpfull. it takes forever to get anywere if you have to stop and put hoses back on every 20 miles. I have a powermax3 and was running it on level 3 while towing.

Eric, clean the end of the metal tube with Simple Green on a rag, then clean that off with another rag dampened with nothing but water on it. (don't want to get water inside the hoses or tubes... )

After it dries, take a can of hairspray to the metal tube ends. That should make it sticky enough to hold good. Get the clamps back on square ! Mine fights back, doesn't want to go back on right, no matter how much I threaten it ! It's the weird angle of that stupid downtube... .

I don't see what year truck you have, my 98 kept comming off on the turbo side (also only while towing). It got to the point I was fixing it about once per hour when towing.



A member of TDR sent me the hoses off his 99 (pay it forward we call it, where I send a used K&N to another guy in exchange)



The 99 hoses were about 3/4" longer, which gave me more clamping space. I glued them on with 3m Weather strip adhisive and have not had a problem since.

thanks

thanks for the advice Tom, I used a k/n oily air filter to see if it would breath better and I think that it oiled things up inside. I'll try the simple green and clean them up. The spray adhesive sounds like it would help also. thanks again.

Check all the mating surfaces very closely. Make sure there is no mold lines (raised ridges) in the cast parts. Oddly, the slp may me caused by the other end of the hose.



Another way is to go with constant torque clamps. Cummins furnishes RG Ray clamps for the charge air fittings on our "C" series engines.

Use a torque wrench at least once to get a feel for how tight the clamps really need to be. They should be much tighter than most folks would ever consider doing by feel alone. Of course I don't remember the exact torque, maybe someone else will chime in.
