MAINTENANCE
COOLING SYSTEM
The Deutz 2011 Series engine uses a robust, heavy duty
oil cooler system to cool the engine. The cooling system
will benefit from periodic inspection and cleaning.
1. Disconnect the air intake hose. Remove the three nuts
and torx screws (Figure 41, Item 1).
2. Remove 3 bolts that mount the air filter bracket to the
engine (item 2) and the two bolts holding the lifting
bale (Item 3).
3. Remove the air box (Item 4) and lifting bale as a unit,
exposing the oil cooler unit.
4. Use a nylon bristle brush to gently brush the underside
of the oil cover to break loose any accumulated dirt
and debris.
5. Using compressed air, carefully blow from the top of
the oil cooler to remove lodged dirt and debris. Blow
out any dirt out of the air box.
6. Use compressed air to next blow accumulated dirt and
debris from the fan air intake, fan, and fan tunnel.
7. Using a non-caustic degreasing agent, soak entire oil
cooler and let sit for several minutes. With low pressure
water, such as a garden hose with a spray nozzle,
thoroughly rinse out oil cooler and air box.
8. Re-install air box cover, air filter assembly and mount,
and tighten air intake hose connector.
Refer to your engine manual for additional information.
