Maintaining Your Ford’s Diesel Engine: Service Tips

Trucks with Ford’s Power Stroke diesel engines don’t just get driven. They go to war every day. Towing heavy loads, conquering job sites, and racking up brutal miles, they endure punishment most vehicles will never know. And the best part? They thrive on it, ready to do it all over again the next day. But while they can happily take a beating, they won’t tolerate neglect. So, you will need to know a few things about Ford diesel engine maintenance.

Oil and Oil Filter Change

Oil and filter changes are important for any kind of vehicle, but they are especially key for diesel-powered ones. While oil in a gasoline engine mainly lubricates, diesel engine oil does a lot more. It not only keeps everything moving smoothly but also helps cool the engine and cleans carbon buildup from the pistons and liners. How often you change your oil and oil filter depends on your engine and how much you’re working it.

If you’re towing heavy loads or tackling tough, off-road conditions, you’ll be looking at more frequent changes; think 3,000 miles for a 7.3-liter. On the other hand, if you’re cruising highways with moderate hauling, your 6.4-liter may stretch it to 10,000 miles. The good thing is that you don’t have to guess. Ford’s Intelligent Oil Life Monitor tracks everything from load to temperature, so it’ll let you know exactly when it’s time for an oil change.

Fuel Filters Change

You might not control the diesel quality at the pump, but you can control how well your engine defends itself against contaminants like water and metal debris. Water, in particular, poses a significant threat because it can lead to corrosion, drop fuel efficiency, and impair performance. So, be sure to drain the water separator once a month or whenever that ‘Water in Fuel’ icon lights up.

Other fuel filter/s might not need such frequent attention, but it’s still essential to monitor them. Ford recommends installing a Motorcraft replacement fuel filter after every 15,000 to 22,500 miles under normal driving conditions. Of course, if you’re dealing with special driving conditions, you’ll want to replace it sooner.

Coolant Nitrite Strength Check

Diesel engines run a lot hotter than gas engines, making effective cooling systems essential to prevent overheating. One way you can ensure things are in check is by keeping an eye on coolant nitrite strength every 20,000 miles for a 6.4-liter or 15,000 miles if you’ve got a 6.0-liter, 6.7-liter, or 7.3-liter.
