About belt & hose replacement.
Drive belts and hoses are wear items. A failed belt can take out charging and cooling at once, so replacing worn parts is cheap insurance.
A mobile mechanic can look at the unit where it stands, whether that is the roadside, a yard or a jobsite. That can avoid a tow and shorten downtime when the fault is suited to on-site work.
