Engine cooling system

The radiator is located in the engine compartment, on the right-hand side of the engine, and cools the diesel engine.

The expansion tank for the coolant is also located in the engine compartment, behind the engine.

Specific safety instructions

• Dirt on the radiator fins reduces the radiator’s heat dissipation capacity. To avoid this:

☞ Clean the outside of the radiator at regular intervals. Use oil-free compressed air (2 bar (29 psi) max.) to clean. Maintain a certain distance from the radiator to avoid damage to the radiator fins. Refer to the maintenance plans in the appendix for the cleaning intervals.

☞ In dusty or dirty work conditions, clean more frequently than indicated in the maintenance plans.

• An insufficient coolant level reduces the heat dissipation capacity as well and can lead to engine damage. Therefore:

☞ Check the coolant level at regular intervals. Refer to the maintenance plans in the appendix for the intervals.

☞ If coolant must be added frequently, check the cooling system for leaks and/or contact an authorized Wacker Neuson service center.

☞ Never add in cold water/coolant if the engine is warm.

☞ After adding the expansion tank, make a test run with the engine and check the coolant level again after stopping the engine.

• The use of the wrong coolant can destroy the engine and the radiator. Therefore:

☞ Add enough antifreeze compound to the coolant – but never more than 50 %. If possible use brand-name antifreeze compounds with anticorrosion additives.

☞ Observe the coolant compound table

– see chapter 6.9

Coolant compound table on page 6-4.

☞ Do not use radiator cleaning compounds if an antifreeze compound has been added to the coolant – otherwise this causes sludge to form that can damage the engine.

• Once you have filled the expansion tank:

☞ Test run the engine.

☞ Stop the engine.

☞ Raise the lock lever.

☞ Remove the starting key.

☞ Let the engine cool down.

☞ Check the coolant level again.

☞ Close and lock the engine cover.

Environment

Use a suitable container to collect the coolant as it drains and dispose of it in an environmentally friendly manner!
