My new 85 Westy radiator has a pinhole leak.
I cleaned up the fluid on the front bumper and it's green :(

I think that means it's coolant with phosphate.

I'm wondering what to do here.  I can't take it back so we move forward.

I can get a radiator from Bus Depot for $150.

What are suggestions from the list?  Is it worth it to get the radiator
replaced or patch the existing one?

I'm thinking that if there's one leak, more will show up.  The leak's a
tiny one on the front sprays water out through the front grill.

I don't know how long it's been running green fluid.  I have lots of
records of factory maint on this rig by previous owner.  I'm hoping
green fluid's been used a short time (i.e. prep it for sale?).  Dunno.
Is there anything I should do to help deal with effects of running
phosphate fluid (assuming green = phosphate).  I'd get the system
flushed at any rate.
