Yeah I guess I should of mentioned mine was tested there about 8 years ago. my shop man who has a shop in the same town less than a mile away, took it there to be tested.

something else to look at. Link: Charge Air Coolers | Vista Pro Automotive, LLC

i guess so. she was nasty and arrogant. it was actually cheaper from freightliner. my dad's truck is a 94 and def. the original and its fine. i do plan on getting a new truck or building a glider in a few years so this one should last. the local cat dealer said it should only be a hour to 2 hours to do so it'll keep the cost down. freightliner wanted $700!
i think i did call them but i could not get the part number off the CAC.

Hi all, These are all fine for truck engines, but for larger diesel engine charge air coolers, you should try Vestas aircoil A/S in Denmark (www.vestas-aircoil.com)
