Mercedes G500 Pre-Purchase Inspection & Coolant System Repair

Vehicle Model: Mercedes G500

Issue Reported: Coolant system failure with coolant leakage outside the garage.

Recently, We had a Mercedes G500 that was coming for a pre-purchase inspection, and an unexpected turn of events that thankfully happened at the right place and time.

A customer brought in their Mercedes G500 for a pre-purchase inspection. They were considering buying it and wanted our expert eyes to give it a thorough check before finalizing the deal. Everything was scheduled, and the team was prepared to conduct a comprehensive assessment of this beast of a vehicle.

However, things didn’t go as smoothly as anticipated. Just as the G500 was about to enter our garage, something quite dramatic happened. The coolant system gave way, resulting in a spectacular coolant blast right outside our service bay. It was a mess – coolant was everywhere! While this was an unfortunate incident, it was a relief that it didn’t happen on the road, potentially putting the driver in a dangerous situation.

The incident turned our pre-purchase inspection into a more urgent repair job. Our team swiftly moved into action, diagnosing and addressing the issue with the professionalism and efficiency we’re known for.
