Introduction To determine if a coolant additive recharge is required, check the nitrite strength of the coolant using the coolant nitrate test strip kit (Acustrip 3-way Antifreeze Test Strip). If the nitrite strength is above 800 ppm no action is required. If the nitrite strength is between 800 ppm to 300 ppm add 32 fl. oz. (946 ml) of engine coolant additive, Motorcraft VC-8 or equivalent. If the nitrite strength is below 300 ppm, flush & refill the cooling system. Fuel and turbocharger cooling system (F-Super Duty only) The fuel and turbocharger cooling system contains a cooler which is mounted on the turbo interstage U-tube on the left side of the engine. The cooler's function is to regulate engine fuel temperature and cool the electronics that support the turbocharger. You may hear the auxiliary coolant pump running up to 10 minutes after the ignition is turned off in hot weather or if you are towing heavy loads. This is to control the temperature of the turbocharger. Engine governed speed The engine governor is controlled by the PCM. The PCM controls fuel input to limit maximum engine speed. It will not, however, prevent engine overspeeding resulting from downshifting at high vehicle speed or by descending steep grades at too high a vehicle speed for the selected transmission gear. If your vehicle is equipped with a manual transmission, refer to Manual transmission shift speeds in the Driving chapter of your Owner's Guide for maximum vehicle shift speeds in various gears. Do not exceed 4,000 rpm. Maximum engine governed speed is 3,700 rpm. Excessive rpm can only be achieved by manually downshifting at too high of a vehicle speed. Operating the engine beyond the governed speed can cause severe engine damage. Speed control (F-Super Duty) If vehicle speed goes outside a predetermined range from the set speed, the RES (Resume) function will not reset vehicle speed. Vehicle speed will need to be reset with the SET +/- button after reaching desired speed using accelerator pedal. 6 2010 Econoline (eco) Supplement (supplement), 1st Printing USA (fus)

electronics that support the turbocharger. You may hear the auxiliary
coolant pump running up to 10 minutes after the ignition is turned off in

The engine governor is controlled by the PCM. The PCM controls fuel
input to limit maximum engine speed. It will not, however, prevent
engine overspeeding resulting from downshifting at high vehicle speed or
by descending steep grades at too high a vehicle speed for the selected
transmission gear.
If your vehicle is equipped with a manual transmission,
refer to

for maximum vehicle shift speeds in various gears. Do
not exceed 4,000 rpm. Maximum engine governed speed is 3,700 rpm.
Excessive rpm can only be achieved by manually downshifting at too
high of a vehicle speed.
Operating the engine beyond the governed speed can cause
severe engine damage.
