Ford Service Tips for High Altitude Driving

Check Engine Air Filter

One of the very first things you should do before driving your Ford at high altitudes is to check the air filter. If you are driving at high altitudes regularly, it is a good thing to change the air filter more often. That's mainly due to the presence of thin air at high altitudes. With thin air, your Ford engine will have to work hard to draw in air. By having a clean air filter, you can ensure proper airflow at all times. This can help the engine to prevent power loss and function effectively.

Use Appropriate Grade of Fuel

Fuel with a higher octane rating helps mitigate issues like pre-ignition, detonation, and spark knock. These problems are more likely to occur when driving at high altitudes. Using 87-octane fuel above 5,000 feet is not necessary in most Ford vehicles (performance vehicles excluded). That is why most gas stations here in Colorado sell 85 octane.

Inspect Spark Plugs

The increased demands on your engine make properly functioning spark plugs critical. Spark plugs should be inspected around every 30,000 miles per Ford service guidelines. Faulty spark plugs will impact combustion efficiency even more significantly at high elevations.

Check Oxygen Sensors

Malfunctioning oxygen sensors can cause improper readings of oxygen levels to your car's computer. This negatively impacts the air to fuel ratio and engine efficiency at high altitudes. Have oxygen sensors tested and replaced as needed for peak operation.

Adjust Timing If Applicable

In some older Ford models, adjusting ignition timing can help offset the impacts of high elevation driving. Advancing the timing delivers more combustion pressure. But only attempt timing adjustments if you have the proper knowledge.

Inspect EGR Valve

The Exhaust Gas Recirculation (EGR) valve redirects exhaust gases back into the combustion cycle. This cools the engine and reduces emissions. But issues with the EGR valve often appear at high elevations first. Have it tested and cleaned regularly above 3,000 feet.

Carry Extra Coolant

The boiling point of coolant drops at higher elevations. This increases the chances of overheating. Carrying an extra gallon of coolant provides peace of mind in case you need to top it off. Use Ford approved coolant only. This will help you keep peace of mind as you drive in high elevations.

Consider ECU Tuning

Getting your engine control unit (ECU) tuned by the Ford dealership optimizes engine parameters for the conditions. Many Ford trucks in particular can benefit from custom tuning when driving for long periods at elevations over 5,000 feet.

Run Fuel Injector Cleaner

Dirty fuel injectors compound altitude-related drivability problems. Regularly using quality fuel injector cleaner helps remove deposits. This aids proper fuel atomization and injection at high elevations.

Descend Occasionally

When driving across high mountain passes, descend to lower elevations whenever feasible. This gives your engine and transmission a break from working so hard in thin air. Allow components to cool down to help prevent overheating issues.

By following these Ford high altitude service tips, your vehicle reliability will improve. Schedule service more frequently and get repairs done promptly when driving the mountains regularly. With proper maintenance at altitude, your Ford will deliver confidence-inspiring performance even at 10,000 feet.
