Before you start
- To prevent severe scalding, let engine cool down before removing coolant pressure cap. Turn cap slowly, and do not open it fully until the pressure has been relieved.
Procedure
- Check the engine oil level; keep the oil level near as possible to the dipstick high mark without overfilling.
- Check the engine coolant level; coolant should be about 3/4 inch (18 mm) below the radiator cap lower sealing surface. Do not check while the engine is hot.
- Make sure the fuel tanks have sufficient fuel and that the fuel system is primed; check for leaks and tight fittings.
- Check that the entire exhaust system is tight, no combustible materials are near the system, and gases discharge away from building openings.
