JasonTL · 05-30-2013, 06:55 PM

Hey all,

So, I've noticed I have a coolant leak. I traced it and it seems to be coming from the freeze plugs on the left and right sides of my engine, directly above/behind the engine mounts. I can barely reach it with my fingers and there's no way I can get them out without removing the engine(which I myself cannot do).

I'm wondering, is it worth trying some Bars Stop Leak? I know it's not a permanent fix and I plan to replace all 8 freeze plugs but I don't really have the funds to do that currently.

The car is an 88' GMC Suburban 350.

Advice, ideas, experiences?
