hey i had the motor out of my car and I was lookin at it and noticed like 4 big 19mm plugs. I took one out and found a buncha metal shavings (motor was toasted, no big deal) but..

wtf is this plug thing and what purpose does it serve?

looks like a cleanout for the cooling system. kinda odd.

 

I have no idea what the bolt is for but the metal shavings cant be good

 

lol
looks like a freeze plug,
thats were your coolant runs,
idk if its actualy called a freeze plug tho, cause Freeze plugs ive seen are pressed in not tapped, but those were on v8s


ps your motor looks extremly dirty, i wouldnt have gotton my tools near that thing...
lol jk sucks the motors gone tho

 

i believe that hole is from the casting process and they plugged it afterwards..also thats how u drain the block

 

replies make sense, thanks for the shouts. yeh the motor is toasted, so don't worry about the metal shavings. I doubt they'd be in there if the motor was still good.

 

i learn something knew everyday, cool

 

on the front side near the transmission right..? that's where the block heater accessory is installed for colder climates. it replaces that plug and has a wire that you plug in to a standard wall outlet for power.

only reason i know is because i bought a motor that had one installed. no one needs a block heater in SC.. haha.

 

thats crazy! ive nevr heard of one of those, now i gotta google some pics..

 

looks like the threads where shreading.

 

yeh a block heater, that's the kind of complex answer i was lookin for. a cleanout for the cooling system is too boring and uneventful.

thanks for the shout.

 

its a core plug. it where they get the material out when they cast it. the block heater is made to go in it. just like other core plugs/freeze plugs.
