What Are Turbo Coolant Lines?

BMW, S63, N63, Turbo Coolant Lines, Coolant Leak, Turbo Coolant HosesTurbo coolant lines are designed to do exactly what they sound like they would do. They help retain cooler temperatures for the turbo on your car by rerouting coolant through a constant feed and return cycle. Over time, these rubber connecting Turbo hoses can dry out. They will eventually crack and leak coolant since they are constantly being exposed to extremely hot temperatures both internally and externally.

 

It can be commonplace for these Turbo Coolant Hoses to leak for a very long time without any noticeable signs.  This is because the hoses lie beneath a cover, and the coolant will usually dissipate when contacting the hot engine before it can become a visible issue.

Applications

The Turbo Coolant Lines that we typically come across are found on the S63 and N63 BMW engines. The ‘Hot V Configuration,’ can be found on a variety of BMW V8 cars such as some 5-series and 7-series cars, along with models such as the X5, X6, M5, and M6.

Symptoms of Failing Turbo Coolant Lines

BMW, S63, N63, Turbo Coolant Lines, Coolant Leak, Turbo Coolant Hoses, Leak coolantOn the S63 and N63 engines, the Turbo Coolant Lines are in the direct path of the excessive heat that comes off of the engine. Over time the constant heating up and cooling down of the rubber components will result in imminent failure. We have discovered failing Turbo Coolant lines as early as 60,000 miles, and most cases are in serious need of repair by the time they reach 100,000 miles.

Symptoms of Failing Turbo Coolant Lines would include coolant loss, a coolant smell, or sometimes even visible smoke coming from the engine bay. Once the rubber coolant lines begin to fail, the coolant has nowhere to go and leaks onto the hot engine components where it will burn off and smoke. Eventually, a low coolant warning light will emit if the coolant level gets too low, followed by smoke. If these symptoms are ignored, it could cause detrimental damage to your engine by overheating it.

Other times, there are little to no external symptoms of failing Turbo Coolant Lines and we end up discovering that they are failing once we remove the engine covers.
