Diesel VW Vanagon T3 Coolant Hoses – Part Two – Radiator Hoses

March 9, 2010

Not surprisingly, the 1982 Diesel Vanagons have a unique radiator, as 1982 gas Vanagons were still aircooled.  Starting in 1983, a new style radiator was used for both gas and diesel models.

The ’82s and ’83s share the smaller (1.25”) diameter metal coolant pipes, while later gas Vanagons moved to larger (1.5”) diameter plastic coolant pipes.

Note that 1982 models also have an additonal metal feed pipe leading from the long underbody coolant pipes to the top of the radiator, while the later radiator style uses a rubber hose for the feed from the underbody pipes.

See Part One – Diesel VW Vanagon T3 Coolant Hoses – Engine Compartment – for details on how to read the information below:

2 Diesel Vanagons have a unique radiator, as gas Vanagons were still aircooled.  The next year, everyone go the same radiator, gas or diesel.  '82s also have a metal additonal metal feed pipe leading to the top of the radiator from the long underbody coolant pipes.  '83s also share the smaller (1.25”) diameter metal coolant pipes, while later gas Vanagons moved to larger (1.5”) diameter plastic coolant pipes.
