10.7.5 Servicing the cooling system
Scalding hazard due to hot coolant!
Never open the cooling system when the engine is hot or under pressure!
Allow the engine to cool or use the protective gloves!
Service the cooling system according to the inspection intervals specified in these operating instructions!
Turn off the engine immediately if the temperature indicator on the dashboard lights up. If the temperature
indicator lights up, the engine or the hydraulic oil, or both, have become too hot.
The hydraulic oil cooler is located in the rear of the wheel loader behind the engine radiator. The engine radiator is
mounted behind the diesel engine. It is accessible by opening the hood. The temperature indicator light is
connected to two temperature sensors, one located on the engine and one on the hydraulic oil tank. To determine
whether the engine oil or the hydraulic oil (or both) has become too hot, disconnect the cable from one of the two
temperature sensors.
