Heater Core - REMOVAL & INSTALLATION
CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

How do i remove the fan wheels from my 92 accord heater motor?


Difficult to describe without pics, but…:
Once you’ve removed the glove box (I assume you’ve done this, and maybe you already have the motor out, in which case you can ignore most of this down to the underlining)
If the vehicle is equipped with air conditioning, remove the strap bolt (between the two nuts for the evaporator on the left and the two nuts for the blower housing (the housing is probably white) on the right, just a bit lower than those) then the blower under-cover and the three blower housing retaining nuts (two nuts at the top, already mentioned, and the nut at the bottom, which is roughly between the evaporator on the left and the blower housing cover on the right).
Pull the housing out far enough to unplug the electrical connectors (at the lower right edge, right above the kick panel) and remove the blower assembly housing.
If you’re replacing the blower motor itself, or either of the blower fan wheels, separate the two halves of the housing, remove the motor, remove the retaining clip(s) and remove the fan wheel(s). Easier said than done in may cases. The wheels, from heat and cold over many years, become very set on the blower rod. You'll have to work them off using whatever break-free lube you can find to do it, and a good deal of slight twisting, etc.
Installation is reverse. Then check for proper operation, before you put them back.
Hope this is at least helpful.

How do you replace the blower motor on 92 accord wagon - where is it located?


Disconnect the negative battery cable (if you have an anti-theft radio, make sure you have the code).
The blower unit is located in the dash, behind the glove box.
Remove the glove box and the glove box frame(damping screws on the sides and two screws underneath).
If the car isn’t equipped with air conditioning, remove the heater duct between the heater core and the blower assembly housings. Then remove the three blower housing retaining nuts, pull the blower housing out far enough to unplug the electrical connectors (at the lower right edge, right above the kick panel) and remove the blower assembly housing.
If the car has air conditioning, remove the strap bolt, the blower under cover and the three blower housing retaining nuts, then remove the blower assembly as previously described.
If you are replacing the blower motor itself, or either of the blower fan wheels, remove the motor, remove the retaining clip(s) and remove the fan wheel(s).
Reverse procedure to install.
Hope this helps you.

  1. Disconnect battery ground cable, then drain cooling system.
  2. Disconnect hoses from heater core.
  3. If equipped with A/C, remove evaporator/blower housing as follows:

    3. Remove console, if equipped.
    4. Remove lower instrument panel attaching screws, then the lower panel.

    7. Cut evaporator/blower housing to heater core housing retaining strap, then disconnect heater control cable.
    8. Pry retaining clip from rear of blower housing flange, then remove the three retaining screws.
    9. Working from engine compartment, remove evaporator/blower housing attaching nuts, then the evaporator drain tube, Figure 1.
    10. Remove right kick panel, then the instrument panel support bolt.
    11. Pull right side of dash outward, then rotate housing downward and towards rear of vehicle until studs clear dash panel. Remove housing from vehicle.

Figure 2

Personally, I'd pressure test the cooling system then look at the heater core to see if it leaks. It may just be a loose clamp or leaky hose.

Also can check the forum jpmagazine.com

I hope help you; good luck (remember rated this).
