Description
This TRP is being issued to address ISX12/ISX15 CM2350 Fault Code 3568 occurrences on
all Paccar (Peterbilt and Kenworth) vehicles with a particular exhaust/aftertreatment
configuration (see Attachment B for more details). This action will mitigate failures caused by
urea crystallization inside the diesel exhaust fluid (DEF) dosing valve. By adding a negative
slope to the DEF input line in the direction of the valve, the DEF is able to dissolve the

Reroute DEF doser hoses
Applies to vehicles with “Crossover” Exhaust configurations
Crossover style exhaust refers to an arrangement of the DPF and the SCR which are mounted on frame rail
brackets. The DPF and SCR are mounted just below the frame rail. The interconnecting piping routes the exhaust
stream from the DPF, over the driveline through the DEF doser and into the SCR. The DEF doser (decomp tube) is
mounted in between the frame rails.
Figure 1 Crossover exhaust (frame rails not shown)
Step 1.
Read this guideline
Step 2.
Proceed to the vehicle. Resolve any Non-emissions related pending codes that are on the truck.
Step 3.
Unfasten the DEF injector hose, upper and lower coolant hose from any brackets and other harnesses
Step 4.
Loosen the Marmon clamps on each side of the DEF doser (decomp tube) (do not remove)
Step 5.
Install standoff bracket and frame clips (DEF Injector hose page 4)
Step 6.
Secure hoses in proper routing (DEF Injector hose 4 and Coolant hoses page 5)
Step 7.
Rotate DEF doser (decomp tube) if required (DEF doser orientation page 6)
Step 8.
Tighten Marmon clamps on DEF doser (decomp tube).

Maintain a 10 degree upward slope from the horizontal
Maintain a continuous downward slope to the doser injector of at least 18”
Tie strap DEF doser injector hose to top of the standoff bracket with the upper coolant hose
Tie to frame clips, make sure that the forward frame clip is pointing up and the rear clip is pointing down.

Coolant hoses
Figure 6 Separate coolant hoses
Upper coolant hose
1. Route this hose vertically up from the injector as much as possible.
2. Maintain at least 35 degrees upward slope from horizontal
3. Maintain a minimum of 10” of hose rising before routing in a different direction.
4. Tie strap this to the upper portion of the standoff bracket to ensure good separation from the lower
coolant hose.
Lower coolant hose
1. Route this hose horizontal or pointing down.
2. Maintain a minimum of 10” of hose horizontal or pointing down before routing in a different direction.
3. Tie strap this to the frame bracket (not the standoff bracket) to ensure good separation from the upper
coolant hose.

DEF doser orientation
The DEF doser injector may be rotated to help position the hoses.
•

•
Optimum position is 80 degrees from vertical, or 10 degrees from horizontal.
It should not point up less than 45 degrees of vertical.
Do not point the injector horizontal or facing down.

Reference: Standoff bracket dimensions (K028-2491-1)
The important dimension to maintain is the 41.5 mm between the lower and the upper hole. This distance
provides the proper separation from the upper and lower coolant hose to the DEF injector.
