I have an 85 GMC S15 with a 2.2L Isuzu Diesel engine. Just recently I have replaced the fuel and water pump, both work great now. Until the timing belt broke. Now I have searched and searched but found no help as to how to change it. If anyone out there knows the ins and outs of doing so, that would be super. I also started this thread for those seeking information regarding this breed of vehicle.

Thanks in advance for your input!
