BMW 7 Series Coolant Leak Fixed: Local Mechanic Shares Cost-Saving Repair Method

Philadelphia, PA – A local automotive specialist, Harris Automotive, recently addressed a common issue plaguing BMW 7 Series owners: a persistent coolant leak. The problem was traced to a fractured connector on the vehicle's auxiliary water pump, a component often requiring extensive labor to replace due to its intricate routing around the engine and turbos. According to the mechanic, the traditional repair involves replacing the entire rubber hose assembly, which can add several hours to the repair time. However, after thorough research, Harris Automotive discovered that it is possible to replace only the broken connector, significantly reducing the labor involved. “This connector is what broke and caused the coolant leak,” explained the mechanic in a video detailing the repair. “The problem being, this rubber hose wraps around the back of the engine, comes around to the other side, and wraps up under and around the turbos.” In addition to the primary leak, a secondary auxiliary cooling hose was also found to be leaking. Both issues were resolved by replacing the specific broken parts and installing new clamps, rather than undertaking a full hose replacement. Following the repair, the cooling system underwent a vacuum test to ensure the integrity of the new connections. The test confirmed no vacuum leaks, indicating a successful and durable repair. This approach not only fixes the immediate problem but also provides a more economical solution for the customer, avoiding unnecessary labor costs associated with a full line replacement.
