Freeze plug size in block?

[70dusterpink]

Had a freeze plug blow out of the passenger side rear block..

Engine is a 70.... 318....

Went to the parts store and they can't tell me what size the freeze plug are?

Are they 1 5/8"?

Anyone have a part number to pick one up at autozone...

Dorman lists them as 1 1/4". i'd go mesure one but the garage is locked and it's dang cold out there, 45F... go ahead and laugh all of you that get a real winter :glasses7:

So are they 1 5/8 or 1 1/4?

This plug is on passenger side farthest back.

1 5/8 if you can't reach well get the rubber plug will save you allot of frustration

Get ready there is two on the back of block that are more than likely ready to go. They are also 1 5/8. I perfer brass plugs with a little permatex #2 on the edge and drive them in.

ahhh, the big ones are 1 5/8", little one in the front and in the heads 1 1/4" thanks.

ya get ready to at least pull the trans. it's worth pulling the motor to do all of them. makes it easy to clean all the crap out. you'll be amazed how much there is...

good luck
