Coolant Vent Line Bypass Kit

The RADHAUS 95B.1 MACAN Coolant Vent Line Bypass Kit addresses a known weak point in the 2015–2018 Porsche Macan 3.0L and 3.6L models. The OEM coolant vent line, made entirely of plastic, is susceptible to becoming brittle due to heat cycles and age, often leading to cracking, failure, and significant coolant leaks. This can result in dashboard warnings and roadside breakdowns, especially on vehicles around 60,000 miles or more. This kit is recommended as preventative maintenance or as a solution for existing leaks. Replacing the factory vent line typically involves removing the intake manifold, a labor-intensive and expensive procedure. The RADHAUS kit simplifies this by re-routing the vent line across the front of the engine, connecting directly to the coolant reservoir port without requiring intake manifold removal. This significantly reduces installation complexity and time, with most DIY customers completing the job in 1–2 hours and saving on labor costs. The kit features custom CNC-machined aluminum fittings with a black anodized finish, aluminum T-fittings, high-temperature silicone coolant tubing, and an OEM-style quick-connect fitting for the coolant reservoir. This plug-and-play design replaces fragile original components with durable materials built to last longer than the vehicle's life. This kit is designed for 2015-2018 Porsche Macan 3.0L and 3.6L (95B.1) models, including S, GTS, and Turbo variants. The RADHAUS brand has established a reputation within the Macan enthusiast community for providing well-engineered solutions.
