*** REPLACE THIS LINE WITH YOUR MESSAGE *** <...> Last week I was driving my 1980 Pontiac Phoenix to college, on a rather warm day, with several hundred pounds of crap in the back, when the "TEMP" dummy light came on. I pulled over and opened the hood, and discovered that coolant was spurting from three small pinhole-sized leaks in the radiator, facing the fan. I made it to a service station, and the mechanic there sold me some "Radiator Stop-Leak", a gummy white liquid which, when poured into a radiator, will supposedly plug up small leaks. Well, the stuff apparently worked; I was able to drive the remaining 60 miles of my trip without problems, and have driven 200+ miles since without further leakage. My question is: anybody out there had any experience with this "Stop Leak" stuff? How long can I expect it to last? Is it feasible to have the holes in the radiator repaired (soldered or something), or should it be replaced? How much can I reasonably expect to pay for repair or replacement? Thanks in advance for any advice/input any of you netters can contribute. -- Mark Vita Dartmouth College USENET: {decvax,cornell,linus,astrovax}!dartvax!markv ARPA: markv%dartmouth@csnet-relay CSNET: markv@dartmouth

We put some Stop Leak in our farm tractor in 1971 and it held until last November. Although, it's used often, it doesn't get the daily use a car gets. Your mileage may vary :-). Anyway, we had the radiator boiled, repaired (soldered), and pressure tested for about $36. This is taking it out yourself and taking it into the shop. Also, check it for leaks when you re-install it. Tightening the bolts can cause certain stresses which will open holes that seal themselves when the bolts are loosened. > Mark Vita Gregg Mackenzie denelcor!gmack

Anyway, I ended up with about 16 holes in the radiator. I soldered 15 of them, but one was hidden in the core. So I poured in a can of the "glop" and it worked fine. I never did remove the glop, and the radiator worked fine for 20,000 miles. It is often claimed that this stuff will gum up your heater core so that you won't have any heat in winter. I did not find this to be the case. I think this may be true of some of the powdered stuff you put in the rad. I definitely recommend only the liquid. -- Gordon V.
