What's wrong?
The engine drive belt tensioner on a 2023-2024 Micro Bird G5 School Bus keeps the engine drive belt tight against the pulleys. The belt turns key engine accessories, including power steering, the alternator, and the water pump, so those systems keep working while the engine runs.
On affected buses, a second air conditioning compressor kit replaced the original GM tensioner with an Oliva Torras tensioner. That replacement tensioner is not strong enough to hold the belt at the right tension. The belt can move on the pulleys, become loose, or come off, which can stop power steering assistance, charging, or water pump operation and increase the risk of loss of control, loss of power, or engine overheating.
There is no warning sign before failure. Micro Bird traced the issue after an unusual noise from the engine drive belt was reported during inspection, but owners should not rely on hearing a noise before the belt loosens.
Who's affected?
Both model years point to the same engine drive belt tensioner area, grouped under belts and associated pulleys.
