I have a 1996 sea ray 450 da and the CAT mechanic that serviced the boat last indicated they were frozen and did not want to break them. I need to remove hoses and the cooling system in slip and unsure if there is a safe way to do without closing the sea cocks. I have no experience with the correct amount of force and what "binds" or fixing? Is their a solution or spray that will loosen them? What advice do you have for these?
