I know it is an S-5 engine, electric omp, ten blades on the fan. etc. Is there any tells that i can look for to figure out exactly what year it is. Some parts are marked N-374 and some are marked N-370 Also i thought there was suppose to be a serial number on the water pump housing, but I dont see one.

Does anyone know of a vendor that makes replacement up pipes for that plastic pos.
Thanks

 

N374 and N370 are just driveline harness part numbers, and reference to the layout, not the year or model.
