That link was working for me before, now it's not for some reason.
You can't link search results. The link is only good one time, for the user who initiated the search.
If it was an A/C car, I could give you the basic steps. I'm sure a non A/C car is different. I'm sure it is wrong, but I would start by removing the heater cover on the engine side of the firewall, then looking for the studs that come trhough the firewall to hold the heater core box to the interior side of the firewall. You might have to remove the control cables to get the box in a position to get the heater core out.
I have never dealt with a non A/C car, so I am just guessing. Hopefully if my guess is way off, somebody will gladly and quickly correct me!!:yes:
