NISSENS brand of Denmark. Best quality we have found for the Vanagon. If you have air conditioning you will need to drill a few small holes in the horizontal metal lip to accomodate the condensor mounts.
Older radiators are often partially plugged by years of use. Long overdue coolant changes (did you know the coolant is due to be changed every 2 years?) and well meaning owners adding Stop-Leak type products plug up many of the fine capilaries inside a radiator.
