S10 Blazer Heater core
I have been having troubles getting out the heater core on a 2001 Blazer. I've gotten the dash back to uncover the whole heat/ac module, now how do I get the engine side bolt off? I can't seem to fit my hand in there. Is there a trick to it?

.....good luck man....
- <LI type=1>On vehicles with automatic climate control only, cut the outer layer of the A/C evaporator and blower module in order to access the service access cover.
- On vehicles with automatic climate control only, remove the service access cover mounting screws (1).
- On vehicles with automatic climate control only, remove the service access cover (2).
- On vehicles without automatic climate control, remove the blower motor resistor. Important: Mark and use the same mounting bolt for the heater/vent module during the installation process. Other mounting bolts are longer and will obstruct the operation of the temperature door.
- Remove the heat/vent module mounting bolt through the blower motor resistor or service access cover opening.
- On vehicles with A/C only, remove the right wheel house panel.
- On vehicles with A/C only, raise and support vehicle.
- On vehicles with A/C only, remove the front right tire.
- On the Utility only, remove the A/C evaporator and blower module heat shield screws.
- On the Utility only, slide the A/C evaporator and blower module heat shield toward the front of the vehicle.
- Remove the 2 lower heat/vent module mounting nuts.
- On the Utility only, remove the A/C evaporator and blower module heat shield bracket.
- Remove the bottom right heat/vent module mounting bolt from inside the vehicle. Important: The heat/vent mounting stud has a flange on the inside and cannot be removed from under the hood. Stop turning the stud after the threads are off the heat/vent module.
- On the Utility only, while an assistant inside the vehicle pulls the bottom right corner of the heat/vent module approximately 2.5 mm (1 in) back, remove the 2 heat/vent module mounting studs.
- On vehicles with A/C only, lower the vehicle.
- On vehicles with a 2.2 L engine only, remove the engine wiring harness bracket located at the rear of the intake manifold.
- Remove the HVAC module mounting bolt located at the lower left side of the heater core to heater hose connection.
- Remove the HVAC module mounting nut located at the lower right side of the heater core to heater connection. Important: The heat/vent mounting stud has a flange on the inside and cannot be removed from under the hood. Stop turning the stud after the threads are off the heat/vent module.
- On the Utility only, loosen the HVAC module mounting studs until the threads are free from the heat/vent module.
- Disconnect all of the electrical connectors from the HVAC module.
- Disconnect all of the vacuum lines from the heater assembly.
- Disconnect the heater hoses from the heater core.
