Could be a leaking head gasket
It would help to know which motor you had. Detroit Diesel, Caterpillar, and Cummins motors were all available options during that model year. Which engine options specifically were available depends on exactly what model Freightliner you have. It could be either an 11.1 or 12.7 60 Series Detroit, it could be a 3206, 3306, or 3406E Caterpillar, it could be the L10, M11, or N14 Cummins, etc.
The possessive form of the noun caterpillar is caterpillar's.Example: The caterpillar's colors are black and red.
if it is two colors then it would be a two tone colored caterpillar.
Remove the serpentine belt then remove the water pump bolts and any attached hoses. It would help to know what year, model, or engine size.
Caterpillar C series, Cummins IS series, or Volvo VED series.
Would not recommend using it .. emergencies only and not with 100% load. 645 requires a larger flow than 567.
Not sure what your trying to do but the year, make, model and engine info would help.
Engine speed sensor faulty. Dead battery or batteries. Loose or dirty battery connection. Dead spot on starter.
This would be a model year 1967 Type 2, or bus engine.
This would have been an 1500 cc engine out of a Type 1 Beetle model year 1968 through 1969.
I would strongly suggest to get a manual for you model.
