Does it say Engine Prot? means that you might be low on fluids such as coolant and the longer you run with it it, it will start to slow down the engine until u stall out....happen to my cat c7 in my freightliner. and it turns out i blew my cooling system.
That depends on what engine you have.
Depends on what motor it has.
That depends entirely on which engine you have.
Bottom of the coolant reservoir.

On the left side of the engine.
Need to know what engine you have in order to answer this. In 2003, Freightliner had the option of Detroit, Cummins, Caterpillar, and Mercedes-Benz diesel engines.
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.
The engine fan switch is probably in the 'on' position.
Depends on the engine in the Freightliner truck. Some require as little as 2 gallons, others require 11 gallons.
