	Clean
4	Thoroughly clean cap of expansion reservoir and surrounding area	Even minute particles of dirt, introduced into the hydraulic components, can result in malfunctions and damage to the power steering.
		Assembly cleaner	*BR00.45-Z-1028-04A
5	Detach cap from expansion reservoir
	Check
6	Check seal of cap; replace if necessary
7	Check oil level
	Specified gear oils (cars, cross-country vehicles) - survey		BB00.40-P-0231-01A
		In the case of expansion reservoirs with oil level marking on the vent protection tube or dipstick in the cap, the oil must be between the "MIN" and "MAX" markings when the vehicle is at operating temperature. When the oil is cold, the oil level must not fall below the "MIN" marking. In the case of expansion reservoirs with oil level marking on the inside of the reservoir (arrow), the oil must be approximately level with the marking when the vehicle is at operating temperature. When the oil is cold, the oil level must be 6 mm to 8 mm below this marking.
8	Checking power steering for leaks	If the oil level is too low: ↓ Determine and rectify the cause of the leak against a separate repair order.
9	Install in the reverse order
