Crack in radiator? leaking fluid...





im having a leak on the inlet side of my BeCool radiator. the coolant is dripping down the plastic liner and onto the floor. while only being a small puddle (size of a small pancake), this is starting to be concerning to me. it only does it off and on, but i've noticed it does it on really warm days, ie 85* or more. days like 70*, its fine.
any ideas what it could be?
also, could/should i put that coolant leak stop in the fluid to block to leak? or is that not good for the water pump.
tips guys??? it is appreciated!!!
