Flush versus top-off
A top-off raises the level without addressing why it dropped, while a flush replaces fluid that has aged. When the reservoir keeps going down, we locate the leak first so the repair holds.
How a Road Wrencher visit works
We need an engine cool enough to open the cap, the correct fluid on hand, and room to turn the wheel lock to lock.
- Step 1: We diagnose it. Hydraulic or electric assist, leaks, belt condition, and whether the pump is the source of the noise.
- Step 2: The exact shopping list. The spec on the cap and the number of bottles required.
- Step 3: Flat-rate exchange. Cycle the wheel, set the level, and purge air from the system.
