Cleaning the radiator's heat exchanger

Remove the radiator grille. If the dirt is mixed with oil,
first spray cold degreasing agent and wait
approximately 5 minutes. Then flush the radiator with
water jets from the engine compartment. Dirt mixed
with oil, can be due to a leaking hydraulic oil cooler.
Contact an authorised service workshop for repair.
