Diesel Engine! We replaced the V6 engine that had over 195,000 miles with a small VW 1.9 TDI AHU. It was from a 1997 Jetta. This engine had about 90,000 miles on it. The timing belt, water pump, front and rear seals, rocker cover gasket were replaced. The intake manifold was cleaned out. Stainless steel upper and lower radiator lines as well as stainless steel exhaust front pipe. The truck also has a rebuilt clutch as well as a new slave cylinder and master cylinder.
