Diagram for bolt pattern for evaporator for the air conditioner

which engine do you have?

FOR THE 2.2L AND 2.5L ENGINES TO REMOVE WATER PUMP THE AIR CONDITIONER COMPRESSOR AND BRACKET NEED REMOVING AND ALTERNATOR AND BRACKET HAS TO BE REMOVED BEFORE WATER PUMP CAN BE REMOVED.

Replacing the heater core in a Pontiac Sunfire is a very difficult and complex process. The heater core is kept within the car's heating/air conditioning module behind the instrument panel. So many other parts have to be drained and removed from the car to reach the heating/air conditioning unit that you may be better off leaving this to a professional mechanic--especially one licensed to work on air conditioning units.
Things You'll Need:

• Wrench
• Container
• Air conditioning reclaimer
• Hose clamp pliers
• Screwdrivers
• Heater core
• R134a refrigerant
• Recharge service hose

1. Removing the Core
   • Make sure the car is cool, the front wheels are facing forward and the ignition switch is off. Drain the engine coolant by removing the drain plug at the radiator and letting the coolant pour into a clean container, then do the same at the engine block's drain plug. Recover the refrigerant by connecting an air conditioning reclaimer to the system high and low side fittings as its instructions state.
   • Disconnect the evaporator lines to the evaporator by removing its bolt and disconnect the heater hoses from the core by loosening the hose clamps with clamp pliers. Remove the drain tube from the evaporator case. Disconnect the negative battery cable.
     
   • Remove all the trim covers and panels from the instrument panel; some of these are screwed on and some require a flat bladed tool. Remove all air distribution ducts from the panel, the air bags, the steering wheel, the radio, the tilt and washer levers and all electrical connectors, then unscrew and remove the instrument panel from the car. Unbolt the cross vehicle beam, remove its wiring harness and remove the beam.
     
   • Remove the air outlet in the floor. Disconnect the wiring harness for the heater/air conditioner and the electrical connectors at the blower's motor and resistor.
     
   • Remove the heater/air conditioning module by removing its attaching bolts and the assembly screw. Remove the heater cover case by removing its heat stakes and screws and remove the heater core.
     
2. • Install the replacement core into the heater/air conditioner module, then re-connect the heater core cover case. Install the assembly in the vehicle, aligning the mounting bracket to the front of the dash slot and mounting bolt hole. Reconnect the electrical connectors and wiring harness and install the floor air outlet.
     
   • Reinstall the cross vehicle beam and every component of the instrument panel. Reconnect the negative battery cable.
     
   • Install the drain tube back on the evaporator case. Connect the hater hoses and the evaporator lines.
     
   • Recharge the air conditioner. Connect a can of R134a refrigerant to the air conditioner's low side service fitting with a recharge service hose and a high pressure gauge to the high side fitting. Open the service hose valve while the car runs with the A/C at the max and let the vapor flow until the gauge reads between 225 and 250 PSI.
     
   • Refill the cooling system at the radiator filler neck. Use fresh coolant if the old liquid is dirty in any way

Simply follow the steps

Disconnect the battery's negative cable and set it aside where it can't accidentally snap back onto the terminal.

Remove the car's accessory drive belt. Disconnect the belt shield by removing its two 10-mm bolts, push up on the tensioner by hand, pull the belt off the air conditioner or water pump pulley and remove the rest of the belt. Take note of how the belt loops around each pulley.

Open the cover containing the alternator's electrical connectors and disconnect them. Remove the bolt on the coolant expansion tank then detach the tank from its clip and secure it away. Detach the power steering reservoir, engine wiring loom bracket, ground cable and evaporative emission canister purge valve.

Unscrew and remove the alternator's first bolt on its right side. Unscrew the second bolt on the left and disengage it fully from the bracket; it cannot be removed from the alternator. Remove the alternator from the engine.

Install the new alternator, placing the built-in bolt within the bracket and tightening it first. Insert and tighten the second bolt.

Replace all other objects set aside in the reverse order they were detached. (evaporative emission canister purge valve, ground cable, engine wiring loom bracket, power steering reservoir and coolant expansion tank). Plug in the electrical connectors and replace the cover over them.

Replace the accessory drive belt. Loop it over all the pulleys except the one on the air conditioner. Retract the tensioner upwards as you did before to fit the belt on the A/C pulley.

Reconnect the battery cable.

I dont know what you need a bolt pattern for exactly, usually you just need to locate the starter. Disconnect all the wires from it, noting their locations, and unbolt the bolts and it should come right out.

For the rear assemblies, there are two bolts per side. Look INSIDE the bed in the corners (behind each light location. The bolts are 10mm with a phillips pattern in the center. You can use a wrench, socket, or screw driver.

Locate the rubber drive belts. It will have at most three items with pulley wheels being driven by it.
Power steering (if you have it)
Air Conditioner (if you have it)
Alternator (allways there)
The alternator will have electrical cables running from it. It looks something like this depending on your model.
