About Diesel Service & Repair
Diesel Motors Require Special Maintenance
|Your diesel powered vehicle is different than a regular gasoline vehicle and requires special operating considerations. They are affected differently by cold starting and oil/filters are critical to performance. Below you will find information to help you get the most from your diesel vehicle. If you have any questions, or need service, just call or contact us. We have 14 Ford certified diesel technicians who are prepared to handle any of your diesel needs.
Why Diesel Oil & Filters Are Critical
Much more than in a gas engine, your diesel engine oil level, viscosity, and contamination level are key performance factors. Diesel oil filter's design and quality are critical to your vehicle's oil viscosity and cleanliness due to the higher engine temperatures and peak stress levels the engine goes through.
Today's diesel engines require special oil grades to perform properly, not just any oil will do. If you fail to maintain the engine properly, replacement can cost more than $10,000! Is it worth losing work time, when qualified diesel professionals are available, both day and night, to keep you on the road and at work?
Cold Starts & Performance Problems
There are several things you can do to reduce cold start & performance problems in your deisel vehicle.
- Purchase the proper ultra-low sulphur content fuel. You should buy biodiesel rated as B5 or be using Ford Cetane Booster if you are buying biofuel rated as only B11, which is below what your diesel needs.
- Reduce excessively long idling as it can cause EGR contamination problems.
- Make sure you allow glowplugs to warm up properly before attempting to Start the vehicle. The colder the weather the longer it will take. Make sure failed glowplugs are replaced prompty.
- Understand that to achieve your diesel’s full power rating it must warm-up to specified operating temperatures.
- Make sure that you visually inspect and drain the Water/Fuel Minder.
- Utilize Engine block heaters in very cold weather.
- Utilize Ford Anti-Gel as the diesel fuel will begin to gel under 9 degrees.
- Make sure you change your Engine oil and filters every 200 running hours and that your oil level at the proper level on the dipstick.
- Make sure Fuel filters are changed every 15,000 for normal duty and every 10,000 for severe duty. Lack of fuel pressure from clogged fuel filters can cause injector failure and poor performance. Use only Motorcraft filters as they are specially designed with tight tolerances for optimum performance and reliability.
- Inspect air filters and coolant every 5,000 miles and use only Motorcraft products.
- Utilize the Severe Duty Maintenance Schedule.
- Have Ford Diesel Certified Technicians perform any necessary repairs on your vehicle. Due the technical complexity of the new high performance diesel engines, Ford does NOT Pay for any warranty work performed by dealers unless a Ford Certified technician who has completed all the latest technical training classes is performing the work. They want it right the first time. Why would you want to use less on an engine that can cost $12,000 to $15,000 to replace?
