This aluminum and plastic radiator with frame and oil cooler fits 2013 & 2014 Cascadia models. The core size is 35 3/4" x 38 1/2" x 2 3/16." Must compare to Ace #43647PF before ordering; check OEM numbers. For aluminum and plastic radiator without frame see Ace #43647P. It is imperative the correct length bolts be used when mounting the charge air cooler, rock guard (if equipped) and surge tank. In most cases, the CAC has three mounting bolts the same length and one longer bolt with rubber spacers. The Surge Tank has one bolt that mounts through the radiator frame and has a spacer that needs to be used. Failure to carefully install the bolts/washers/spacers properly, can cause the bolt to go through the frame and damage the side plate on the radiator. This places stress on the adjacent tube and will result in the tube failing. This is an installer issue, not a manufacturing defect, thus not covered by warranty.
