3. DIFFUSER ASSEMBLY
During stationary regeneration, exhaust gases
temperature may reach up to 1200°F (650°C) at
the DPF outlet. The diffuser decreases the
exhaust gasses temperature to 475°F (246°C)
approximately, at 6 inches above the diffuser.
The diffuser is an important component of the
exhaust system and must remain on the vehicle
at all times. Operating the vehicle without the
diffuser may seriously damage the vehicle.

3.1 DIFFUSER ADJUSTMENT
Should an adjustment of the diffuser position be
necessary, first remove the DPF compartment
roof ventilation grill.
CAUTION
To prevent paint damage and fiberglass
overheating caused by hot exhaust gases, the
diffuser louvered cover must be flush with the
roof surface or may not exceed the roof
surface more than ¼ inch (6mm).
CAUTION
Tighten clamps properly in order to prevent
any movement of the diffuser assembly. An
impact wrench is necessary.
1. Loosen the clamp securing the diffuser
assembly to the ATD.
2. For proper angular position, make sure that
the two edges shown on figure 10 are
parallel with each other.

3. Using a straightedge, adjust the diffuser
assembly level. The top surface of the
warning plate fixed on the diffuser louvered
cover must be flush with the roof surface
(fig.9). It may exceed about 1/4in (6mm).
Place the straightedge as shown on figure
11.
