no, this is not the inlet part of the radiator. If you are looking down, at the plastic top of the radiator about an inch to the left of the inlet (right at the centerline under the coolant hose coming from the inlet and going to the overflow)is about a 2 inch crack. hope this helps
fyi, i inspected the inlet and it is already
re-inforced. btw, about 3 months ago, I had the radiator be rudded out. I wonder if they had changed the plastic top as a part of the rudding process....
