Crank the engine and observe the fuel flowing into the container. Route a hose from the fuel drain line to a clear container and open the drain. (A reservoir that drains back after the engine has not been operated for a period of time can cause a hard start and die condition.) Filling the reservoir will allow the system to prime faster facilitating starting. Remove the inspection plug in top of reservoir and check to see if the oil reservoir is full. The level in the oil reservoir should also be checked. Refer to the lube oil chart in the service manual or operator's manual for the correct oil selection for temperature conditions. Oil that has had extended drain intervals will have increased viscosity (become thicker) and will make engine cranking more difficult and starting less reliable at temperatures below freezing. 10W-30 oil is recommended for cold ambient temperatures. Single weight or 15W-40 oil is not recommended for cold ambient temperatures. A milky white oil indicates possible coolant contamination and will have an ethylene glycol odor.Ĭheck service records for correct oil type and viscosity for the vehicle operating temperature. Usually if a substantial amount of fuel is in the oil it will have a fuel odor. If the oil level on the dipstick is overfull it is possible the engine was incorrectly serviced or fuel is diluting the oil and filling the crankcase. If there is no oil or very little oil in the crankcase, the injectors will not operate. Check oil level with dipstick when vehicle is on level ground.
