Intercooler Piping Clamps

action · **Posted:** Fri Aug 25, 2006 9:11 am

I was looking over the intake system of my CRD and was surprised to see rather standard looking hose clamps on all of the intercooler piping....especially after reading that these engines are pushing up to 26lbs boost right out of the box. Has anyone had any trouble with boost leaks at the clamps?? My freinds that are into turbo cars all had to use special turbo hose clamps (similar to those that GM use on the Duramax engines) to get the hoses to stay sealed.

I was thinking the same thing. My diesel Suburban, with a whopping 6-8 lbs of boost, has clamps superior to the clamps on the CRD. I noticed some clamps at West Marine that appear equal to the clamps on the GM diesel. $12-$18 per and you need 4 of them.

The hose from my turbo to the intercooler blew off going down the highway. Of course the mechanic just stuck another 20 cent hose clamp back on there.

Yep, not only did I notice that but when I heard what sounded like air escaping I saw that there was blowby around the intercooler inlet. Sure enough, I loosend it up (the clamp was reasonably tight) and cleaned out the CAC tube. I put everything back together, making sure everything was tight, and sure enough the noise went away... I thought about just doubling up on the clamps since there is enough room to do that.

Are you refering to spring loaded clamps (has a small coil spring built into the screw adjuster). Take a closer look at the CRD clamp, has a flat spring built into the band. The spring tensioned clamps help but no substitute regularly checking and tightening.

We need the constant & equal tension clamps like are used on the VW TDI's to hold the hose's in place.

Maybe you can post a picture of the clamp type we need. All these words in here just get me confused as to what type of clamp I have, vs. need. I'm a visual guy

I don't own a VW TDI any more, one of the guys here with a TDI will have to do that for us. The clamps that come with the CRD are Euro-Seal Hose clamps that are pretty good for this application and some prefer them over the constant equal tension flat spring type used by VW on their turbo's.

What about rubber hoses for the charge air. I want metal ones that won't expand :shock:

. I think I am going to make some.

I would prefer a metal one too. A few quick tips from big diesels designs. You will have twice as many hose connections with a solid pipe (in this case, oily connections). To relieve engine vibration, the connection boots are usually designed with a balloon/accordian mid-section that flex (not just a piece of straight hose). The weight of the pipe usually has to be supported with a bracket to dampen vibration.

If it wasn't just an oversized coolant hose I would feel better but they are way to soft and flexable. Stainless steel braided would be cool.
