They are about $30 a piece. Car may have two, I'm not really sure. Labor shouldn't be over $30 or $40, I wouldn't think.

SOURCE: need a heater core diagram for a 91 mazda b2200

The only thing to do is get a diagram from the MAZDA dealer parts dept. "A few parts fell out" is way to vague to help you.

Need instructions for replacing 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.
f74-01.gif 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.

On my dash board panel there is a flashing hold button. i have no idea what is causing it. every once in a while the transmission seems to slip though


Unfortunately, there's only 2 causes of this. One the computer is located under the heater core( center of dash) & it's leaking on the computer. Replace the heater core & pcm(computer). Or it needs a transmission. Sorry for the bad news,.

it attaches to the A/C evaporater core inside the a/c module that is in/behind the dashboard. To access it you would need to remove the dash assembly and then remove the a/c/heater core assembly. Not an easy task for the do it yourself person as special tools and equipment are nneeded to recover and recharge the a/c system itself
