Before you start

  • High air cleaner restriction can cause turbocharger seals to unseat, causing oil to be drawn through seals and into engine

Procedure

  1. Measure air cleaner restriction using vehicle mounted gauges
  2. When 25 in. H2O (6.25 kPa) is sensed on the vehicle mounted gauges, replace the air cleaner element
  3. For convenience, air cleaner restriction can be measured at high idle (no load) when 12.5 in. H2O (3.13 kPa) is measured, the element must be replaced

Specs & torque values

  • 25 in. H2O (6.25 kPa) restriction limit for replacement
  • 12.5 in. H2O (3.13 kPa) limit for high idle measurement
