Best Heater core for Volkswagen Golf

Spend the extra couple of bucks and get a Valeo heater core. It is a pain in the butt job but not actually hard.

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.

I found a Febi unit it at a local euro parts dealer that somehow always has the most obscure mk2 parts in stock when I need them. Ill give the Febi a try but if this one fails I'll have to bypass it like a hack.

I've installed a new Mahle/Behr heater core on my MK4 Golf and it popped at the crimps after a few thousand miles. Went with an OEM Valeo after that.

My buddy bought a Meyle for his MK4 and it unfortunately leaked within a few months and he had to redo the job.

I replaced the heater core in my 1991 mk2 8-valve RV coded engine in May 2022. I replaced it with a new Valeo unit I got off FCP Euro and the install went just fine. Every year I do a mid-winter start-up since I live in Minnesota and after running it last night for about 20 minutes the heater core popped and dumped a ton of hot coolant in my driver and passenger footwells...
