Hyundai Ioniq (AE) 2017-2025 Service Manual / Engine Clutch System / Clutch System / Reservoir. Repair procedures

Removal

1.	Turn the ignition switch OFF and disconnect the battery (-) terminal.

2.	Remove the engine room under cover. (Refer to Engine Mechanical System - "Engine Room Under Cover")

Drain the hydraulic oil from the reservoir using a syringe.

•	Do not spill brake fluid on the vehicle, it may damage the paint; if brake fluid does contact the paint, wash it off immediately with water

DIsconnect the reservoir hose (A).

•	Disconnect the reservoir hose, and then Be careful not to leak the fluid.

Remove the reservoir (A) after loosening the bolts.

Tightening torque :

21.6 - 26.5 N.m (2.2 - 2.7 kgf.m, 15.9 - 19.5 lb-ft)

Installation

1.	Install in the reverse order of removal.

Refill the specified lubricants in the reservoir and then perform the air bleeding using the GDS.

Specified lubricants : Brake fluid DOT 3 or DOT

Quantity : Remove air from the hydraulic line and theninject hydraulic fluid to the reservoir so that it comes between the MAX and MIN levels of the reservoir.

(1)	Engine clutch inspection line learning and diagnostic information.

(2)

Removal of air from engine clutch hydraulic pressure line.

•	When using a vacuum-pressure equipment to inject hydraulic fluid, the vacuum pressure should be no more than 2.5 torr and the injection pressure should be between 2.3 - 2.5 bars.

•	If it is impossible to inject hydraulic fluid using the above condition, be sure to remove air from the hydraulic line of the engine clutch at a temperature between 0 - 40°C.

(3)	Engine clutch/motor resolver adaptation.

(4)	Stabilization of the engine clutch hardware transfer torque.
