Christopher,
           I would suggest the citric acid soak
approach.   500 grams of citric acid to a gallon of
water. (isloate the radiator from the engine)  Remove
the big hoses from the the back leaving them connected
to the big pipes and flush house pressure hot water
through them in both directions.   Plug the ends and
add the citric acid and let sit for a week.   Repeat
the hot water flush.
It will either kill or fix your radiator

Subject: T3 -Radiator removal question?

Hey all, I checked the archives but didn't find
exactly what I was
looking
for.

I am going to remove my radiator to check for
blockage, cracks , etc..

I haven't had the radiator fan come on in over a year,
and my van
overheats
in traffic (time+idle+no forward movement). The fan
works, the switch
works,
the system is bled properly, and after a 30 minute
drive in 90 degree
heat, the
radiator is about 100 degrees..

I suspect there is some major blockage in there...

I want to try and clamp off the input and output hoses
with my ez
clamp-do-jobs so the system all the coolant doesn't
just flow out.

**Is this feasible? Has anyone else ever successfully
clamped off the
hoses?
Also, how much coolant should I be prepared to have
come out of the
radiator
(non -A/C model)? Should I park the van on a steep
driveway (nose up)
to help
keep the coolant from draining out the front? Am I
just doomed to let
all the
coolant drain? ;)

TIA, after being an Air cooled nut for so long, I
think I am just
scared by
the mysterious water cooled system;)

C.B.
