RTC or batery backup low ..thank
On the left side of the engine.
I'm assuming you mean 12.7 Detroit Diesel 60 Series engine? IIRC, it's 11 gallons.
I believe it wasn't until 2001 or 2002 that the engine fans on the Detroit diesels came on automatically when the temperature rose. You're probably required to flip the engine fan switch on manually.

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.
Either replace the entire line, or find the break and fix it with a compression fitting.
The engine cover should have it displayed.
On my 2000 International with a Detroit series 60 engine the water temperature sensor is on the back of the engine, passenger side in the cylinder head. Gears
usually in front of the radiator!

Need to know the engine. In 1997, most Freightliner models were available with a Detroit Diesel (e.g., 11.1, 12.7, or 14.0 60 Series), Caterpillar (3116, 3126, 3406, etc.), or Cummins (6BT, L10, M11, N14, etc.) engine, and many models from the aforementioned manufacturers were available, as Freightliner makes a wide range of trucks - Class 5 through Class 8. You could talking about anything from an FL50 with a 6BT Cummins to an FLD132 Classic XL with a 3406E Caterpillar. Suffice to say, the routing won't be the same for each truck model/engine configuration.
