Rear heater is nothing. I nominate changing out the pedal assembly. Or even worse ..adjusting the push rod length for the clutch master cylinder.

It's very important IMO to have the rear heater valve on at least partially all year long. Keeping fresh coolant circulating through the rear heater helps prolong its life .

I was just reading somewhere where they said to pre-mix anti-frz and water before pouring in the mix .. rather than add say 1/2 gal a-frz followed by 1/2 gal water to get a 50/50 mix. I have not found that ever to be an issue .. and it would not be for a rear heater core if the valve is kept at least partially open at all times. , all year round.

re rear seat .. inconveniently VW made the plastic ( maybe it's fiberglass ) cover for the rear heater on GL models so it's captured by the bar going across on a Z Bed rear seat. You only have to remove that once .. then you just cut away a little bit of that cover on the bottom ,,,,,,,,,,,,,from then on the cover comes right off. I've had someone tell me that you can cut out that round bar going across there too .. and the Z bed rear seat still works just fine.

wow..I have not found rear seats to be dangerous in any way. R & R many syncro transmissions ? ....they're lots of fun.

I have about 6 rear heater assemblies in my used parts stash.

stay cozy ! scott
