CSF 8198 High Performance All-Aluminum Auxiliary Radiator - Select Mercedes-Benz 2012-2020 (68mm 2-Row)

Fits select 2012-2020 Mercedes-Benz CLA, CLS, E, G, GL, GLA, ML, S, and SL-Class models.

The CSF 8198 High-Performance Auxiliary Radiator is a heavy-duty cooling solution designed to replace the standard 42mm single-row factory unit. This radiator serves a critical role in managing engine water temperatures and acting as the heat exchange medium for air-to-water charge-air coolers in turbocharged systems. By utilizing a massive 68mm 2-row core, this radiator significantly increases fluid capacity to delay the onset of heat soak and keep intake air temperatures (IATs) within optimal ranges.

• 68mm 2-row core featuring CSF's exclusive B-Tube Technology for maximum thermal efficiency
• Ultra-efficient 6.5mm tall multi-louvered fins provide increased surface area contact
• 100% all-aluminum TIG-welded construction for superior durability over plastic-tank OE units
• CNC-machined mounting brackets and OEM-style Quick Connect inlet/outlet for a true drop-in fit
• Included detachable rock guard protects the core from debris and punctures
• Individually leak and pressure tested with a 1-hour mirror-finish hand polish
• Multi-fit design works for both left and right-side positions (sold individually)
• CSF Part Number: 8198

For vehicles equipped with two factory auxiliary radiators, CSF recommends replacing both units simultaneously. This part is designed for maximum cooling performance when used in conjunction with the CSF 8197 Front Mount Heat Exchanger.
