properly sized and fitted radiator hose should not leak; I'd look for a <br>
small crack on the housing, a deformation or other issue causing a leak. <br>
Radiator hoses are pliable and the pressure is low--they should seal <br>
with just a properly installed clamp.<br>
<br>
Permatex Seal & Lock is my go-to for tough jobs, but you're looking at a <br>
semi-permanent 'fix.'<br>
