Yes… that water pump thing… it did seem extremely common for water pumps to fail on Studebaker Avantis…. Some owners felt that, on R2 models, and R1 with A/C versions, too much pressure was applied to the water pump bearings from the supercharger and or A/C system system.
Personally, I think the frequent water pump failures happened because of Avanti owners replacing the original water pump with a standard duty non-flanged type, which really wasn’t designed to be strong enough to take the extra pressure.
