Pressure Testing Radiator
I just had my old 1992 radiator pressure checked .
The guy at the shop had the pressuer up to 19-20psi.
He said that the truck ran the pressure up to about 13psi on on a 4.9 f150.
We did find a few leaks in the water take.
All he did was take the vise grip and bend the small tabs.
This seem to stop the leaks,good as new I hope.
Man I thought I over tighten the outlet on the hose clamp and cracked the fitting.But I got didn't this time.
Can a person but too much on the clamp and crack the outlet on a raditor with a plastic tank by hand with a screw driver?
I was useing a ratchet when I thought I cracked mine.
