My `95 Buick Century V-6 overheating. I found the problem to be a leaking freeze plug on the front head, behind the water pump. How can I get at this plug to replace it?

Whenever I see a system which is leaking from more than one or two places, I do a head gasket check because that tells me that the system is experiencing above normal pressures. the wet floor is a heater core. whether it's a water pump or some other thing near it only you can tell. Actually it rarely happens, but the wet floor could be the hose where it meets the heater core at the firewall; again, only you will be able to tell the difference. if the hose connection looks dry, assume that it is the core itself.
Sounds like you have a leaking freeze plug, you will need to replace it, hopefully it is rusted and leaking and did not pop out due to freezing temp, some of these plugs are in spots thatcan cost alot to replace, the plug itself is a few dollars and new coolant . the cooling system needs to be drained because when plug is removed all coolant will run out , the plugs are all over the block, this is designed to pop out plugs and not crack block if there is not enough coolant and to much water and it freeze in cold weather the water expanding pops plugs and not cracking block, some are behind ****** or bracket and so on, you will need to locate the leaking one and see if it is something you want to do. good day
freeze plugs are normally on the sides of the engines, check to see if hose connected to thermostat housing is not leaking, and also check to see if coolant is coming from the water pump.
Could be a hose..
When you pull into your drive way - when it is hot - shut it off - this is the best time to look for the leaks because after you shut it of the presure builds a bit.. Check the hoses..
Could be the water pump...
ould be a freeze plug gone bad..
