Maintenance
High Restriction Reading
POSSIBLE CAUSES
EXPLANATION
Plugged elements
Ultra fine particles are difficult to remove and cleaning may not sufficiently lower restriction.
Plugged inner element (if equipped)
Replace inner element.
Plugged inlet screens or ducts
Check system upstream from restriction tap for debris, damage, or improper installation.
Heavy snow or rain
Temporary high restriction can occur during a rain or snow storm and it disappears after drying out.
COLD AIR MAY BE SO DENSE THAT HIGH RESTRICTION MAY NOT REDUCE ENGINE POWER
BEFORE ELEMENTS ARE DAMAGED FROM HIGH VACUUM. If gauge is locked up at RED
zone, check elements for damage.
Chassis-Mounted Charge Air Cooler and Radiator Core
Inspection and Cleaning
With the engine off, visually inspect the charge air cooler core
and radiator core assembly for debris and clogging of external
fins. Prior to engine operation, remove any debris blocking the
core.
