About The 2.8L V6:
The Ford Cologne 2.8L V6 is a 60° cast iron block V6 engine built by the Ford Motor Company in Cologne, Germany. The 2.8L engine in the Ranger is the same design as the 2.8 V-6 used since 1974 in the Ford and Mercury Capri vehicles. A unique feature of the 2.8L is the timing gear vs a traditional timing chain (See picture below).
