It is NOT necessary to remove the dashboard.
1. Drain the coolant from the cooling system. Remove caps and clamps from heater pipes.
2. Remove the cap from the heater hose (inside the cabin) and clamps from the heater hoses.
3. Remove the heater core support plate.
4. Remove the cotter pin from the hose clamps and separate the heater pipes.
When the heater pipes are disconnected, refrigerant will flow out. Place a drip tray under the pipes to collect the refrigerant.
5. When all the coolant is drained from the heater core, remove it from the casing.
6. Assembly is in reverse order. Pay attention to the following points:
- a. Replace hose clamps with new ones.
- b. Fasten the hose clamps tightly with a cotter pin to prevent refrigerant leakage.
- c. Fill the cooling system with coolant and open the bleed bolt until coolant flows out. Tighten the bolt when all air has been expelled from the system.
