Reviews of OEM Volkswagen heater core

so far i have determed that u can fit a mk3 vr6 gti heater core/box into a mk1 failry easy and not looose much if any foot/leg room on the passinger side of a caddy cabbin.

When the heater core blew on my '91 Golf, I called VWoA and they arranged for a free goodwill replacement even though the official recall only covers up to 1990 models.

yea the w8 one is larger and freer flowing.

And if it does need a heatercore make sure they use the w8 heater core. VW now is superceeding to that because its a bigger heatercore.
