Need manual that defines how to R & R heater

I would replace CATalitic converter, this car is old, plus a tuneup is 100% necessary , spark plugs wires, ditributor cap & rotor, plus both the air & fuel filters need replaced. change oil & filter. then you will pass emissions test. and your car will run like its suppose too. if you don't do all this , then buy a new car !

Thats because they didnt have them back then: ) If you unhook your battery for 10 to 20 minutes it will reset everything. Hope that helps you out.

Contact this company for assistance with this. I think it requires a bypass amp harness. www.crutchfield.com

YOU WILL NEED TO REMOVE THE DASHBOARD, THEN OPEN THE HEATER BOX AND TO ACCESS HEATER CORE, IT LOOKS LIKE A SMALL RADIATOR. ITS LABOR INTENSIVE

If your problem started with the security light, you need to reset it. To do this, you have to have the code. If it is not in the owner manual, call your local dealership. If you have another question, feel free to contact myself or another. We are here to help you. Thanks for choosing FixYa.

change the heater core!
If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing

• The heater housing is usually under the dash and must be removed to gain access to the heater core.
• Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

The heater housing is disassembled to get to the heater core.
Heater Core

• Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
• Remove the heater coolant hoses.
• Remove the cable and/or vacuum control lines (if equipped).
• Remove the heater core securing brackets and/or clamps.
• Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
• To reinstall the heater core, reverse the removal steps.

When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

you may have air trapped in the system, or there may be a blockage somewhere. usually, a blockage would be in the heater core. to check, remove both heater hoses going into the heater core and try to flush it out with a garden hose. it's also possible that the water pump is faulty.

its usually a tube wrapped in factory tape just pull and itll come off

if you are running an amp, you need a much thicker positive wire coming directly from the battery, i pushed through the clutch linkage grommet on my 85 300zx

no, dry floor, check anti freeze pipe, if there is a leak bu a sealant at an autoshop and tape it up, top up anti freeze, re check for leaks, ya should be good to go
