***Fits all Chevy 4,5 and 6 cylinder Atlas engines. Colorado, Canyon and Trailblazer***
Atlas 4200 slim water necks are in-stock!
These are perfect for 4200 swaps with tight engine bay / radiator clearance, especially if your passenger side rad outlet is on the bottom. These are necessary for basically all Japanese and European cars because of the shorter engine bays, otherwise the original water neck would point directly into the radiator. These are anodized to protect from scratching and corrosion also utilize the factory O-ring seal for both 2002-2005 and 2006-2009 engines.
