freeze plugs

I have a 1984 oldsmobile ninety eight regency and i have a freeze plug that has popped out or is leaking. Would it be best to get all the plugs swapped out which i heard is a whole lot of them and could be costly, or can i just fix this one plug and do the others later?



help me

Do you know where it is leaking, the sides or in the back. When was the last coolant flush?

its leaking from behind the block i think it wont hold water i just got the car recently so i dont know when the coolant flush was last done
