Where are the Freeze plugs located?

There are a couple of these on each side of the block. It appears there is one behind where the oil filter mounts and then close to where the starter is.

I am attaching a picture below of the best view that I could find.

Most manuals do not have this info as a freeze plug is not a typical thing to replace anymore. These are normally done during engine rebuilds and that is not typical anymore.

However, if you need to replace them that is normally due to a leak. So, we just need to confirm where the leak is by pressure testing the system.

I assume you have already done this but just want to make sure.

Below is a picture. There are going to be ones on the other side of the block in about the same locations.

Thanks

It is possible if coolant was getting on the starter that it could damage it or short it out.

However, the way to know for sure is to tell how the starter failed. Do you still have it?
