Toledo Ford Vehicle maintenance



7.3L Diesel Suggested
Maintenance



  • Oil and Filter- Oil change service intervals should be completed as indicated by the instrument cluster message center or every 7500 miles

  • Fuel Filter Change- Change every 3rd oil change or every 15,000 miles(24,140 km) or as indicated by the message center which ever comes first

  • Coolant Check/Change- Initial change at 105,000 miles or 72 months; subsequent changes every 45,000 miles

  • Coolant Strength Check- Check every 15,000 miles or 600 hours

Use the Right Filters


Ford Motor Company can only attest to the quality and exact size of the filters provided by Motocraft. Only Motocraft air, fuel and oil filters were designed specifically for the demands of the Ford Power Stoke diesel engine. Genuine Motocraft filters provide superior filtration and never require adaptors.



Use the Right Oil and Diesel Fuel


API CJ-4 engine oil is required for 7.3L engine to meet federal emission standards. Operations of the 7.3L diesel engine requires Ultra Low Sulfur Diesel (ULSD) fuel.



Use the Right Diesel Exhaust Fluid (DEF)


Diesel Exhaust Fluid (DEF) is required to meet 2010 calendar year exhaust emissions. Operation of the 7.3L diesel engine requires DEF. The DEF tank should be refilled at every oil change to avoid running out. DEF usage will increase when operating under Special Operating Conditions. If the DEF is empty the vehicle will automatically have a reduction in performance or de-rate of the engine until the DEF tank is refilled. Refill DEF tank Motocraft DEF or equivalent.



Take Care of your Coolant


The coolant concentration should be maintained at 50/50 mix of Motocraft Specialty Orange Engine Coolant VC-3-B (U.S.)/ CVC-3-B (Can.) or specification number WSS-M97B44-D and distilled water. The level for coolant should be maintained at the "COLD FILL" range in the coolant reservoir. If you suspect any coolant system leaks or lack of cooling, pressure test the cooling system. Refer to your Owner Guide for additional information.


Engine coolant system strength (carboxylates) should be checked and serviced at the mileage or equivalent hour intervals specified by the vehicle's message center and maintenance schedule. Check coolant strenght using the Rotunda Antifreeze Test Strip kit to determine if additive is required (Rotunda Antifreeze Coolant ELC Contamination Kit#328-00008). If the carboxylate strength with this additive up to two times before the cooling system must be flushed and refilled - Do not add Supplemental Coolant additive if Flush and refill is required.



Take Care of your Fuel Injection System


Diesel fuel quality is critical for reliable engine operation, Motocraft Cetane Booster and Performance Improver, PM-22-A (U.S.) / PM-22-B (Canada) can be added to improve fuel economy,starting ability, and reduce engine wear.


The water separator should be drained monthly or when the "water in Fuel Lamp" illuminates.


Biodiesel fuel must not exceed 20% (B20). To avoid cold weather fuel gelling, add 6 oz. of Motocraft Anti-Gel and Performance Improver PM-23-A (U.S.) / PM-23-B (Canada) to every new tank of fuel.



Cold Start Performance


The glow plug system operates for up to 120 seconds and is completely independent of the "Wait to Start" lamp operation. Always wait until the "Wait to Start" lamp had turned off, before cranking the engine.


To ensure optimum cold weather starting performance, and improve cabin heating, the 120 volt engine block heater should be used during any cold weather operation . The engine block heater is required when the vehicle is to be started at temperatures below -10F (-23C).



Performance Modifications May Impact Your Powertrain


Performance modifications may or may not be the root cause of a powertrain failure. If a non-Ford product (e.g. performance modifications, programmers, modified exhaust or air intake systems) fails or causes a Ford part to fail, the cost of the entire repair and any related damage will not be covered by the Ford New Vehicle Limited Warranty or any applicable Extended Service Plan (ESP/ESC) contract coverage.Oil and Filter- Oil change service intervals should be completed as indicated by the instrument cluster message center
