Where did it leak at. I purchased a replacement radiator and when I placed
the order the salesman suggested after I replace the new radiator,
thermostat and hoses, I pressure test the system. He then went on to say
that I should monitor the pressure and make sure it does not build up to
much. I ask why and he stated from what he seen from radiators that are
returned after someone just replaced it was the radiator busted again due to
vehicle over heating even though it is below the high temperature gauge or
Not sure if I believed him until a few weeks later when my truck overheated.
I pulled over and let it cool down and finally got it home. The problem was
the water pump was bad even though it was not leaking the rubber impeller
was not circulating sufficient water. Replaced water pump and three days
later the end of the radiator started leaking due to seal failure on the
end. So did the seal fail because it got to hot or over pressure are was it
a bad radiator from the begining.
