Does the 2.5 Lima engine have a way to drain the coolant from the engine block? I understand how to drain the radiator. Thank you.

No, engines haven't had those for many many years.

You can knock out a casting plug(freeze plug) to drain the block then put in a rubber expansion plug.

I have used the overflow hose as a siphon hose to drain coolant on other engines, but any smaller hose would work.

There is a 1/4" drain plug on the passenger side behind the motor mount. I replaced mine with a drain valve.
