Скачать или смотреть MCI J4500 AC Leak: J4500 Sisters Part 4

Come along as we make repairs on the A/C system of this MCI J4500 motorcoach. What should have been a straightforward repair quickly turns into something else when things don’t go as planned.

During the job we run into issues that highlight a common mistake many owners and technicians make — using A/C stop-leak products. These products might seem like a quick fix, but they can create bigger problems in the system and make proper repairs much harder down the road.

The moral of the story: don’t use Stop-Leak in your bus A/C system. It can clog components, contaminate the system, and lead to expensive repairs later.
