my newly installed radiator sprung a leak. It appeared where the core is soldered to the top tank but the repair shop said it was the inlet pipe attached to the tank.
I had wondered if I had left the cleanser vinegar in the system too long. The radiator repair shop said maybe or maybe a manufacturing fault, it was not possible to tell.
I am starting to wonder if it was the ridgidity of the rubber hose. the motor moving along plus engine vibration? Or forward movement from the drive train especially since float a motor allows more movement.
The radiator is mounted at the base with springs attached to the bolts as it should be.
I have purchased new softer radiator hose which may reduce transmission of vibration and movement to the radiator.
Does any reader have a comment or idea.
