| TheWrench2Feb.21 | 2021-02-26. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; ENGINE AND ENGINE COOLING. The Wrench - If the right engine cover is leaking coolant on any of the models listed, this could be due to the water pipe causing a gap at the clutch cover side. Replacing the O-ring will not fix the leak. Instead, replace the water pipe. |
