hp 525 leak?
 

Started the 525 and found a leak on the cooler in back of the engine
I did not drain the cooler this winter (missed it)
there are two bolts on the side of the cooler removed one and saw that there is a gasket.
My plan is to replace the gasket but I am afraid I might have
other damage . but won't be able to tell until the cooler leak is fixed
Has enyone else had this problem and am I headed for the right fix ?
It did only look like it was leaking from the caps on the end of the cooler
thanks
