Freeze plug under engine mount
My 1995 has been loosing coolant andI've been topping it off for over a year now. I've got the upper intake manifold off to replace the fuel regulator. I assumed the lower intake gasket was the problem. I pressurized the coolant system. Nothing was squirting but I finally found a place dripping. It's coming from the passenger side motor mount.
Even with the wheel off I can't see the exact place where the leak is coming. I imagined it was a head gasket. Looking at pictures of the block, seems there is a freeze plug under the engine mount (dumb!). The other plug, above the starter is dry. Searched the forum but didn't find any postings about replacing the plug under the mount. My plan is the remove the mount while supporting the engine with a jack and a block of wood under the pan. The only plug I replaced I ended up using a rubber compression type because I couldn't hammer in a metal plug. Will this be the same deal? Anyone done this and care to give me some pointers? |
Christine replaced a block heater on her rig. You might want to check that out. Same thing just the ds.

This info on replacing a freeze plug under the engine mount. Not a blazer, maybe a camaro. They made a special tool to press a new plug in.
https://www.thirdgen.org/forums/tech...eeze-plug.html Someone did an S10 https://www.s10forum.com/threads/any...e-plug.261999/ A good video but the guy took his truck apart. Exhaust, fender, wheel wells, AC, ... Seems others have asked similar questions but no magic solutions. https://blazerforum.com/forum/engine...-blazer-90362/ https://blazerforum.com/forum/engine...cations-13072/ https://blazerforum.com/forum/engine...5-blazer-9019/ |

There are 2 plugs on each side of the bottom block. The plugs near the firewall are accessible however the other two are under the engine mounts. You installed the heater plug in the rear. No way to fit anything under the mounts. Stupid design...
Wondering if I can get the passenger side engine mount off without removing the exhaust manifold. https://cimg5.ibsrv.net/gimg/blazerf...aaaeaee3a6.jpg |
