New heater core

[Durty-Sanchez]

So.. will be attempting a heater core swap in a couple of weeks (and attending to blown relays/wiring that plauges the legacy). Aside from de-gassing the A/C, are there any other things I should be preparing for? New seals? Car is a 94 TT Legacy...

Thanks!

Didnt think youd need to de-gas the A/C. I thought the heater core could be removed seperately?

In that case it's even better! ... I might check the workshop manuals for the BH - assuming much hasn't changed in the world of heater cores (or just wait until my new one arrives and check that..)

its been some time since i replaced mine but i think you can get away with not de gassing. what relay and wiring problems you have, likely heater leak related

Yup, BG Legacy don't need the A/C to be degassed. Did our one a few months back.

Fuel pump relay doesn't initiate sometimes ... its fairly old so I figure it's just getting stuck (comes right after a few minutes). New one will do the trick - unless it's the alarm relays!

In cabin fan relay is also gone (I assume). The main power wire to the fan went some years back somewhere between the relay and the fan (so under the dash somewhere). I ran a new wire and it was sweet for a year but eventually it stopped again. Power gets to the relay but not out of it so it's my main suspect... could be running too much current or shorting out somewhere, potentially I need to add some resistance to the fan if it's drawing too much current or find where the power wire's shorting out.

Stoked about not needing the de-gas!
