Re: Block plug leak
Some good and bad suggestions on here that I'm seeing from my 20+ years of engine experience....
The good....
Replacing the coolant more often. It's like oil. It's not too expensive and is easy maintenance. Every 3 years, mine gets tossed and replaced.
Block plugs are replaced by hitting the edge to knock the plug sideways which will bend it up a bit. Get it taco shaped and pull it out with a pair of pliers. I've seen the slide hammer method done, but I've also seen that do damage to the block.
Another slick idea......why you're replacing the block plug, why not put in a block heater? My tractor has one, my diesel truck has one, even my Subaru has one. It's really like starting a warm engine every time. I see you're in California.....but I'm not sure how warm your part stays. If it drops below 45 degrees and you use the tractor....it's a nice thing to have.
The bad...
Any stop leak is like what Earl said....they do a great job of plugging things up. This includes radiators, heater cores, and thermostats. It's like taking Advil for a stroke....yeah...it'll make the headache go away....but are you really solving the problem?
Here's what you need.
Block plugs: 5 of them to do the whole engine. If you do a block heater, you'll only need 4.

If you're cold and want heat, I found the heater kit for you also.

Here's a video I found on removing them.

WHen you put the new ones in, I usually use a silicon sealer.The forums are a great place to find information....but also a great place to find speculation. Only you can determine the real problems with your tractor. We're here to help you find the correct way to do it.

Re: Block plug leak
Thank you all for the excellent advice! I decided against the additive and was able to easily remove the plug. The video was very helpful. I found a brass plug at the local parts store and installed it with the right sized socket and an extension. I filled the radiator with water and ran the tractor up to temperature with no leaks. I'm going to drain and flush the system tomorrow before adding new coolant. I was surprised to see the back of the old plug was shinny--it looked new with the exception of the spot at the left edge that had corroded through (see photo). I was expecting much worse and am now debating if I'll change the rest or not as a couple of the others aren't so easy to get to.
