Default Freeze plug replacement on 1988

The drivers side freeze plug is leaking on my 88 I just bought. Can anyone give me an idea of the reasonable labor expense for this? Engine has 136K miles.

Thanks

A complete freeze plug kit is $15 or less, so $25 in parts and fluid should get you by. Labor is free if you do it yourself, or shop rate times book time allowance for that individual freeze plug. If it rotted out, this is the beginning a of the end for the rest of them, and I recommend changing the other plug on the same side of the block while there.

Is it the one near the back of the block or the one behind the motor mount? Big difference in cost.

Freeze plugs are easy, pop out the old one, tap in the new one. I use a long socket or a piece of pipe that will just fit inside the plug face, put some high temp sealer around the outside, then tap it in until its flush with the block.Easy as falling off a rock.....Plus you save money for Beer..WW

Its the one next to the front motor mount. The rear one on the same side looks fine, as well as the others.
