(1) The maintenance section should have spares available. These spares
should be included on one vehicle.
(2) Vehicles are more prone to overheating; therefore, ensure extra
coolant is available.
(3) Oil consumption is abnormally high; therefore, check the oil more
frequently.
(4) Electrical components have higher failure rates. The maintenance
must carry extra electrical parts.
(5) Transmissions on the HMMWV may overheat; therefore, stop
frequently to allow the transmission to cool.
(6) On rocky deserts, the HMMWV is more susceptible to power steering
seal leaks. Check the power steering reservoir during stops.
(7) Frequently check the air filter restriction indicator and clean the air
filter as required. Also clean the air filter dump valve at rest halts.
