Now I got some bad news cfauvel... I'm still at it
, granted I've had to do a lot of work besides just dropping int he heater core. Plus limited time and space in small workshop/shed.
Pretty much it's nasty through and through. Here's what I did:
Unhook A/C and heater lines- I do not believe that you can just drop the lower box, as there are clips on the far side that if ripped will screw the box.
Pull off plate in engine bay.
Pull off dashpad, glovebox and inst. cluster.
Loosed lower dash all the way, so only wires from switches are holding it on.
Loosen nuts holding box up, pull box down and out
That's the short of it, to get everything out was a real pain. Plus I had to make some structural repairs to my box. Also i would recommend getting everything pressure tested before it goes back in, including any new parts. Would also be a good time to renew all of the foam peices inside (heater box seal kit). Mine were actually disentigrating.
Good news is I'm almost done, just need a couple screws that gremlins stole to secure parts inside box, then it is to be put back together, and put back in car. Still need to diagnose fan switch problem, but I should have it done soon. (Knock on wood).
