The 2.0l/2.3l/2.5l Lima SOHC 4 cylinder/8 valve engines were used in Rangers from 1983 to 2001, this engine had a timing belt and was a non-interference engine, so if timing belt should break there would be no piston/valve damage.
These engines were built in the Lima, Ohio Ford plant, so often referred to as Lima engines.
In late 2001 Rangers started getting the 2.3l Duratec DOHC 4 cylinder/16valve engine.
This is a Mazda L engine with aluminum block and heads, it uses a timing chain not a belt, the chain is long so could require servicing during the life of the engine, you would hear a rattling noise from loose chain at that time, broken chain is not very likely.
If no rattling noise then chain and tensioner are fine.
This engine design was for transverse mounting in front wheel drive vehicles, when it was put into Rangers with longitudinal mounting it placed a cooling hose connection between rear of engine and firewall, only way to access this connection, if it should leak, is to remove the transmission, or lower it enough to get access to rear of engine.
So if you ever remove the trans for any reason replace this connection and hose "just because", same as you would the rear main seal, preventative maintenance
