Ouch!  Sorry to hear that, but I encourage you to try again.  Mine is
working well.

Van Cafe in Santa Cruz installed the aluminum tank in my '84 Westy in
November, 2016, at 183,400 miles, after the water pump seized climbing
Highway 17.  The plastic tank wasn't involved in the failure, but it was
starting to look worn.  We also installed a new thermostat housing and
80-degree thermostat at that time.

Since then I've driven around 21K miles, including some very challenging
high and hot climbs, and I haven't had a problem with the cooling system
or seen any drips.
