Modern V6 Porsche’s have been plagued by a coolant leak issue. This kit completely replaces OEM Part 946-106-026-060. The original part is entirely plastic, which will inevitably become brittle and damaged with age and heat cycles from the engine. This can cause a catastrophic leak. Lucky owners will smell coolant and catch this leak before the line completely ruptures. Others have been stranded roadside with a completely empty coolant reservoir and urgent warnings from the car to cease driving to prevent engine damage.

If your vehicle has ~60k miles or more, this may be considered an item for preventative maintenance. If you have a coolant leak, this may be the first part to check.

This important line runs from two accessible fittings on the front of the engine, then underneath the intake manifold to the back of the engine. It then ultimately finds it's way to its appropriate fitting on the coolant reservoir.

 RADHAUS Coolant Vent Line Bypass kits replace the unreliable plastic components of the OEM line with parts that are designed to last longer than the life of your vehicle itself. In addition, this kit re-routes the line across the front of the engine, and attaches to the OEM coolant bleeder valve, in place of the original line. Best of all, there is no need to remove the intake manifold.  While space is still limited, installation is now much faster and less complicated - saving significant time and labor costs. Most customers have reported DIY install times of 1-2 hours, typically saving hundreds of dollars in labor charges.

This plug-and-play kit features:

- Custom, CNC machined, black anodized aluminum fittings

- Aluminum T-Fittings

- High temperature silicone tubing

- OEM style quick connect fitting to coolant reservoir 

While this repair is NOT the official Porsche recommended repair procedure for a broken plastic coolant vent line, it has been proven to be a solution that is expected to last longer than the official repair itself. In addition, this kit will save a considerable amount of time and labor since the intake manifold does not have to be removed.

Please note: It is still very important to follow the Porsche recommended procedure for flushing and/or bleeding the coolant in your Macan after the installation of this part.

Purchase of this part constitutes acknowledgement that this aftermarket kit is simply an alternate method of repair, and not directly recommended by Porsche. Install at your own risk.
