1990 80q -- no heat

[James at ringsperformance.com]

I once had a $300 bomber Mercury with this problem. By forcing city water
through the in, then the out, then the in, then the out . . . I was able to
get some flow through the core after 15 minutes or so. Then after running a
few radiator flushes, the heater worked pretty well, with all this work done
from "the outside." YMMV, and I hope the plastic core doesn't pop.

It seems that POs had never added any coolant, so the (soldered brass?) core
was just clogged with iron crap. The in/out/in waste water was bright
orange.
