What are the best options when "recommissioning" and installling an engine that has been in storage for years? This is a Dodge Colt (Mitsu) engine with 10K on it. The engine is perfect except there is rust, (not horrible), in the coolant passages of the block. I don't want to tear the engine down.

Can I clean as much as possible? How? Then install a coolant filter like this?


Any thoughts would be appreciated!

Thanks, Todd

If it is limited to the coolant passages, and is just surface rust there is no need to clean it up. Just run it, and treat it to a coolant flush a few hundred miles after the install.

There are some areas that are kinda flaky rust, but it all very, very dry in there.
I'm going to get that filter to save the radiator.
