Ranger 2.3L 1989 runs cool
1989 Ford Ranger with 2.3L engine
This engine runs cold and never gets to operating temperature. ECTS always shows a code 21. I put card board on the radiator and temp went to normal and no codes. Engine even sounds better.
I changed the thermostat but still same code 21 and engine runs cold.
Any idea?

Not sure what a 21 code is off the top of my head but what temp stat did you put in? You should be running a 195 stat. If that is what you have i'd change it again cause you probably got a bad one, it happens. If you put cardboard in front of the rad and it came up to temp that tells me your stat is wide open. Hope that helps. Carl
