Help! Overheating!

[cale]

I have a 1986 Subaru GL-10 with the turbo. it overheated on me today.
the gauge went up very fast, and i turned it off immediatly. I put some
more coolant in, and i drove it a very short distance home, whick was
about 7 minutes. it was perfect, and i did hear some gurgling along the
way. i hope this is just a sticky thermostat? any other thoughts?
thanks!

If it still has the original radiator then it is well past replacement
time. Having owned 2 turbo wagons in the past I know these radiators
don't last forever. What happens is the tubes inside the radiator become
clogged. Took the last radiator I replaced apart and saw at least 75% of
the tubes were clogged. Just amazed me it still worked at all.
