Re: Radiator leak
Reply #12 –
Back in the 70's, when auto mfrs went to hotter running engines the radiator solder had to be changed (less tin) due to thermal expansion and contraction of the radiators. Because of ignorance I ended up replacing the radiators in both our vehicles. Turned out the antifreeze "times itself out" after about three years due to higher engine operating temps. Since I now routinely change antifreeze every three years I have never had a problem with a radiator, heator core, or engine freeze plugs leaking of failing.
Hopefully newer antifreeze solutions and solders are much better. Also, I hope Brett can chime in with his expertise, along with others, and possibly prevent premature failures.
