Re: Intercooler lines
Despite what your girlfriend or wife says, size does matter.
The better flow is with the larger hoses with few (no) elbows or connectors. You want to rout the hoses as far away from heat as possible and still keep the hose length short. Where possible, insulate the hoses.
BTW, I saw at my local parts store some silicone hoses. Suppose to be real slippery inside. Cost like $8.00 a foot and only came in OD green (ugly). However, I might try to see if they help.
Good luck with your truck. Ya gotta love these trucks.

Re: Intercooler lines
i thought i saw a factory line made for the new cobalt ss, it makes a nice smooth S curve and would allow the lines to be run to the left of the IC through the fender..
shame I can't find the part number or any info on it.

Re: Intercooler lines
This is how I did mine using SS lines and the Cobalt elbows I found in the GM parts catalog....

Re: Intercooler lines
Hey Scrapn,
- Cobalt 3/4" elbows SS... GM part #22707607.... $18 each - three is best, two work
- 3/4" braided SS heater hose from Summit Racing (SPE-39710) .....$29.95 per 10 feet section - two needed
- Derale 7" fan from Summit (DER-16507) $69.88 - one used
- Pump is from ZZ performance - only pulls 2 amps and flows a LOT of water - it's the factory supercharged Cobalt pump - about $110. The pumps from the vendors here on the site work just as well, are a lot less expensive, but draw a little more current - I'm concerned about current cuz I'm also going to add a tranny cooler with a second Derale fan back under the bed.
The hose couplers are Gates items that NAPA keeps in stock.... about $2 each.
Get the 'good' stainless hose clamps that are used for sprinkler systems - very strong and they NEVER rust.
Don't buy the fancy AN-looking fake hose fittings - they don't let the hose slip over the barbs on the IC inlet/outlet, and are so big they look kind of dumb.
My intake temps run 10-20 degrees above ambient regardless of engine temp or length of time running. I'm just running premixed antifreeze right now, but will probably switch to distilled water and water wetter since I don't have to worry about the IC or parts freezing during winter.
Hope this helps
