I know what freeze plugs are for but why do we need them? What if i just fill the holes up with sheet metal or something, weld it and forget about it.
Yes, i have replaced freeze plugs in other cars but it made me wonder...
Tried googling it but all i got are the answers i already know.
HouseCallAuto 2/7/2012The answer is in the name Spoons. If the coolant / water in the block were to freeze to ice, the expansion of the liquid as it turns to ice would fracture an engine block, whereas if there is a "freeze plug" that can "pop out" as it is pushed against by ice, the integrity of the engine block is protected. I can honestly say I have experienced seeing this exact condition once many many years ago where several freeze plugs jettisoned from some car that had a severe overheating issue and then I discovered all the empty holes filled with ice.
Spoon Sports 2/8/2012Thanks Master, so technically, me living in a tropical area will not really be of a problem right?
