I use my 85 westy as a daily driver and have since I got it with 80K miles
and 8K on the rebuild. Some problems that were not indigenous to the
Wasserboxer. Stuff wears out (alternators, O2 sensors, exhaust, CV joints)
and sometimes parts are not manufactured right (had a weird head gasket tear
after the rebuild). I should save and drive something else, but I love it
too much, so at some point, I suppose I will rebuild or swap engines.
While I change oil religiously, the list seems to be of two minds on
Coolant. Do we change it or is it meant to be long term? Mine is 2 years
old, genuine VW. Is there science to back up either position?
