anti freeze coming out from underneath cap

2001 ranger 2.3 liter 5 speed 145k miles

I just changed radiator cap and t-stat seems to be working. Has radiator flushed. For the longest time, I always loose a little anti freeze from underneath cap. It does not matter if I have mostly water or antifreeze in system either.

There seems to be (2) by pass hoses on top or reservoir. Could it be they are clogged or something? Should they be preventing the big air bubble to close at top of radiator cap and cause leakage?

Any suggestions?

thanks

Are you sure it isnt to full?

Checking the hoses to make sure they are not clogged seems like a good place to start.

it could be the radiator cap has a bad seal or the radiatior neck is slightly mis-shapen
