Heat exchanger for high-voltage batteryVX63 with refrigerant shut-off valve for high-voltage battery heat exchanger N542 — VW

🧭 Before you start

Fits: platform code 6Z1

• Renewed: o-rings

Don't miss

• Observe general warning instructions for work on high voltage system .
• To prevent the intrusion of moisture, all components of the refrigerant circuit which have been opened must be sealed with suitable plugs.
• Risk of scalding.The cooling system is pressurised. The coolant temperature may be above 100°C.If necessary, release pressure and reduce temperature before carrying out repairs. — Loosen clamps, and pull off coolant hoses.
• After installing heat exchanger for high-voltage batteryVX63, bleed coolant circuit.

📋 Procedure

1. Observe instructions when working on refrigerant circuit .
2. Observe general warning instructions for work on high voltage system .
3. Remove bonnet General body repairs, exterior55Bonnet; Removing and installing bonnet. [Note: To prevent the intrusion of moisture, all components of the refrigerant circuit which have been opened must be sealed with suitable plugs.]
4. Clamp off coolant hoses using hose clamps up to 25 mm3094.
5. ⚠ Risk of scalding.The cooling system is pressurised. The coolant temperature may be above 100°C.If necessary, release pressure and reduce temperature before carrying out repairs. — Loosen clamps, and pull off coolant hoses.

6. ⚠ Danger from escaping pressurised refrigerant!Freezing of skin and other body parts.Extract refrigerant and then immediately open refrigerant circuit.If the refrigerant was extracted more than 10 minutes before the opening of refrigerant circuit, the refrigerant must be extracted again. The pressure in the circuit will increase due to subsequent evaporation. — Extract refrigerant with e.g. air conditioner service stationVAS 6007A.
7. Remove heater and air conditioning unit .
8. Disconnect connector from refrigerant shut-off valve for heater and air conditioner unit N542.
9. Unscrew bolts (1 and 3).
10. Unscrew nut (2).
11. Pull refrigerant lines off refrigerant shut-off valve for heater and air conditioner unit N542.
12. Remove bolts (1).
13. Remove heat exchanger for high-voltage batteryVX63. [Note: After installing heat exchanger for high-voltage batteryVX63, bleed coolant circuit.]
14. Always renew O-rings.
