Is there a how-to anywhere around here on how to replace a heater core (in an 87 GL wagon)? I have an 86 parts car, would the cores interchange?

The core's should interchange, yes. I put a 93 Loyale core into an 86 sedan once so I think they are all pretty much the same.

 

It's pretty straight-forward.

 

Pull the gauge cluster surround and then the cluster itself. Pull the radiao and the heater control cluster. Pull the glovebox and all the panels under the dash on both sides. Pull the steering wheel, drop the column, pull the dash and put it in the back seat. Yank the heater core "container" and remove the core. You will then want to go to Home Depot and get some replacement foam. Scrape off the old foam, clean the surfaces, and cut/apply your foam tape. Then slide the replacement core into the box and reverse your dissasembly steps.

 

There is a lot of electrical plugs to keep track of so you might want to label them.

 

It's about a 6 to 10 hour job depending on how many you have done in the past. I've done a couple of EA82's, and a Gen 1 Legacy so far. It's not a difficult job just time consuming and annoying.

Dang. I was hoping it wouldn't take that long. Thanks for the walk-thru tho. Sounds like a project for tomorrow

might want to pull the front seats too, so you can sprawl out on the floor on your back, otherwise its really really tight and cramped and you will be yelling alot.
