If you are not already running a newer radiator then that should be your
first step. Be sure to also use the 86+ fan temp switch so the fan will
run sooner and keep your temps from shooting as high first. Putting a
newer rad into an 82 means replacing the 82 plastic fan shroud with a
later metal one and also changing the mounts and hoses. The metal shroud
comes in 2 fan motor sizes. Both sizes were used in all years from
83-91. The larger one is mostly from 86+ with factory A/C. You could use
the later small one to keep it simple and reuse your existing
fan/motor/wiring or get a later larger fan/motor/shroud combo and do the
extra wiring.

These watercooled 82 vans are a small niche and not many people know
much about them. Some of us know too much.
