Diagnostic and maintenance work may only be carried out by authorized personnel using equipment

NOTICE:
• Use only pre-diluted coolant or concentrated coolant mixed with distilled water. Do not use tap
water.

premature engine failure.
• Do not mix heavy-duty diesel engine coolant and automotive-type coolant. This will lead to coolant
breakdown and engine damage.
