Task Instructions
2. Disconnect connector D9089J from D9089P at the heater fan.
3. If the heater core is to be removed, disconnect and drain it by disconnecting the input and output B-nut fittings, holding the hex on the core with a 3/4 wrench and turning the B-nut with an 11/16.
4. Remove the heater core subassembly by removing the four nuts and washers on the carbon support bracket.
5. Using a 3mm ball-end hex key, remove the four screws and washers securing the heater fan and core to the composite bracket.
6. Slide the fan out to pilot’s side from between bracket and heater core. If the heater core is still in place, support it with a stiff wire or cable tie so as not to put loads into the coolant lines, otherwise, it can now be removed.
7. Remove the heater core fittings (2x) and O-rings, retain fittings and discard O-rings.
Verification Method
The task is complete when the heater core has been removed.
