Why is my 1988 ford ranger 2.0L running rough and missing and blowing black smoke
Sounds like it is running rich, could be a stuck injector or a bad water temperature sensor. Is the check engine light on?
SOURCE: exhaust blows black on ford explorer
look for a vacume leak. black smoke means it is running very rich
SOURCE: Replace heater core in 1988 Ford Ranger
allow the system to cool down
take radiator cap loose to release pressure
once pressure is released tighten cap
loosen clamps on the heater hoses in the engine compartment on the pass. side of firewall.
plug or cap off the heater core tubes to prevent spillage when you pull it into the truck
place a trash bag on floorboard in case spillage occurs
remove the five screws holding the heatre core access cover, three on top and two on bottom
carefully pull heater core back and down and remove it from the dash
install is reverse
Hope this helps
