Pressure pump
1 | Attach universal adapter (2) for pressure pump with fine adjustment to expansion reservoir (1). |
Shutoff valves (3, 4) on filling unit (5) must be shut. |
2 | Connect universal adapter (2) to the filling unit (5). |
3 | Connect Venturi nozzle (6) to the filling unit (5). |
P20.00-2342-04
4 | Connect compressed air hose (7) to the Venturi nozzle (6). |
5 | Open shutoff valve (4) until the pointer on the filling unit (5) is located in the green area (- 0.85 to - 0.9 bar). Then evacuate cooling system for just another 2 minutes or so. |
6 | Carefully open the shutoff valve (3) until the hose ( 8) at the filling unit (5) is filled with coolant. |
7 | Close shutoff valves (3, 4), close venturi (6) and allow cooling system to rest for about 1 minute. |
The vacuum should not drop in this time period. Reduced vacuum points to a leak in cooling system. |
8 | Open shutoff valve (3) and fill the cooling system up to top marking on coolant expansion reservoir (1). |
9 | Close shutoff valve (3). |
10 | Open shutoff valve (4) and create pressure compensation in the cooling system. |
11 | Disconnect universal adapter (2) on expansion reservoir (1) and on filling unit (5). |
12 | Connect STAR DIAGNOSIS. |
13 | Follow path "Systems N82 2 (battery management system control unit)- actuations- bleed coolant circuit" in main menu. |
14 | Start "bleed coolant circuit". |
Observe coolant level in the expansion reservoir (1) during the first minute of the ventilation process and top up coolant if necessary. |
15 | Loosely cap loosely on the expansion reservoir (1) and wait until the ventilation process is ended. |
Waiting time about 15 min. |
16 | Correct fill level in expansion reservoir (1) and close off expansion reservoir (1). |
17 | Disconnect STAR DIAGNOSIS. |
