3/4" IC lines

I have been told that there is a thread on here that shows the stock IC lines being removed and replaces with 3/4" heater hose. I guess someone found a hose with two 90 degree bends; one right out the back ot the stock intercooler that bends the hose towards the passenger side and another one about 1 foot or so after the first 90 that will bend it towards the front ot the truck. The reason I ask is because I want to do this upgrade and am not sure if it will kink the hose if I try to make that bend to the front of the truck.

Re: 3/4" IC lines

What I did was hack a piece of the metal line that is a 90" and coupled it to the little piece of hose on the top port off the back of the intercooler. The bottom one is kinda pointed towards the drivers side anyway and it does not kink at all.

EDIT

Thats what I was going to do, just looked and the lines dont kink at all just run them up near the firewall and they wont kink

Re: 3/4" IC lines

Get in good with somebody at the local parts store, they should let you rummage through their small hoses. I was able to find one piece that had both a 90deg, and about a 110deg bend in it. That and a two pack of couplers/clamps set me back around $5-6. I wasn't crazy about the potential restriction of the couplings, but found some that are thin walled and you have to stretch the hose over (heat gun helps), I.D. is nearly the same as the hose. Other than right at the IC, you should be able to find a route that won't cause any kinking. At least until you get righ to the pump (repeat above if necessary). HTHs.

Re: 3/4" IC lines

That is right about finding a parts person that will look. There are lots of the smaller hoses in 3/4" with the angles molded in. Another option for couplers is to go to lowes or home depo and look in the section that fittings for sprinkler systems and plumbing fittings. They have some 3/4' dia couplings that work well for connecting the hoses togather..

Re: 3/4" IC lines

Wasn't there talk about the fittings from the cobalt ss intercooler? They are like 100degree hard fittings that can couple directly to the our upper intercooler and send the hoses in the direction you want them

Re: 3/4" IC lines

X2, 3, whatever, about the parts guy. He or she can also find you the hard plastic connectors for hooking hoses together. Personally I suggest that you run the hoses over the dist and down the drivers side. Why? Because once you do this mod and run the hoses over and down the drives side it makes it much easier to work on the engine. No draining of the IC needed. just unbolt the IC and set it over where the anti-lock brake system is or was leaving the hoses connected. Be happy to post a pic if you want...

One thing I've been contemplating is running black pex or nylon pipe instead of rubber hose. The nylon stuff is pretty light, when compared to heavy rubber hose.

Any further contemplation/ideas/action? I've been keeping my eyes open since you mentioned this, but haven't seen much that is light AND semi pliable.
