Replacement of the Liquid and Cleaning of the system
WARNING: The radiator coolant is under pressure. Follow the Operation and Maintenance Manuals indica-
tion in order to relief the pressure, before removing the cover from the expansion reservoir.
NOTE: For filling or replacing coolant in the cooling sys-
tem, the machine must be parked on a level surface. After
filling the cooling system, start the engine and allow it to
operate at operating temperature for around 5 minutes to
mix the AKCELA PREMIUM ANTI FREEZE and the water.
This procedure must be performed when the machine is in
an environment with temperature below 0°C (32º F).
Turn the expansion tank cap slowly to relieve pressure.
Open radiator drain cock located under the radiator and the
drain cock located on the oil cooler. Let the coolant drain.
Check to see that all hoses are in good condition and the
clamps are not damaged or loose. Replace if necessary.
After draining, flush the radiator with clean water. Be sure
that the water does not contain large amounts of calcium.
Fill the cooling system with a mixture of 50% of AKCE-
LA PREMIUM ANTI FREEZE and 50% of clean water to
about 1 1/4" (30 mm) below the filler neck.
For complete replacement of coolant open the draincock,
located in the expansion tank piping, before start feeding
the system. This procedure is for removing the air from
installation, ensuring the cooling system performance.
