Construction & Design

The coolant tank is expertly fabricated from lightweight yet robust aluminum, chosen for its excellent heat dissipation properties and resistance to cracking or warping under extreme temperatures. The gloss white powder coating not only enhances corrosion resistance but also adds a clean, professional look to your engine bay. The inclusion of a CNC machined billet aluminum cap provides a precision fit and a premium finish that complements the overall design.

The tank’s low-profile architecture removes the need for the stock plastic tank’s bulky engine side bracket, offering improved clearance around the lower front edge of the assembly. This thoughtful design consideration makes the Wehrli tank especially suitable for trucks equipped with aftermarket turbochargers, where space and fitment can be challenging.

Installation & Fitment

Installation is straightforward and user-friendly, requiring only basic hand tools. The kit mounts directly in the OEM coolant tank location using factory mounting points, eliminating the need for drilling or additional modifications. This ensures a clean, professional installation that preserves the integrity of your Ram’s engine bay.
