We know all the different ways people use their diesel vehicles, like pulling trailers, boats, hauling small and large loads and taking adventurous family road trips.

We also provide full diesel maintenance services to help prevent unexpected, and sometimes costly, downtime. 

Scheduled Diesel Repair & Maintenance Services that will help you get the most of your diesel truck over the years and miles:

Oil Change

At Tucker Tire and Auto, we recommend having the oil in your diesel changed every 5,000 miles. This does depend on your driving habits which means it could be needed more frequently if your vehicle is for towing and hauling. Schedule a regular service with Tucker Tire and we'll be ready for you!

Air Filters

During your oil change our technicians will inspect your engine air filter and suggest replacement as needed. Arizona air is hard on air filters, especially during the monsoon season. Keeping your air filter clean assists in the performance of your vehicle, reducing stress on components and improving gas mileage and efficiencies.

Fuel Filters

Fuel filters are replaced during the routine maintenance service of your diesel vehicle as recommended by the manufacturer. Most will recommend changing fuel filters every 10,000 to 15,000 miles. As with oil changes, the fuel filter replacement schedule can depend on your driving habits. You may also notice that some of the newer model engines have 2 fuel filters that will both need to be changed. But don't worry, we've got it covered for you.

Cooling System

Our technicians know that your vehicle's coolant is one of the most important items to be checked and maintained. The temperatures we experience in Phoenix can be rough on our cars, trucks and diesel engines. A coolant flush should be performed as recommended to get the best from your cooling system and overall vehicle performance.

Hard Start Issues

Today’s automotive market offers buyers a variety of diesel choices from light duty engines to one half to one-ton trucks and various cars and SUV’s. Diesels are known for their great fuel economy and performance. Of course, that is only when they are running properly.

During the cold months, (more for our friends up North than here in Phoenix) a problem we hear about from diesel owners is having trouble starting their car or truck. Some describe a rough start and some experience no starting when the temperatures drop. This is due to colder temperatures thickening the oil in the vehicle’s engine. Unlike a gasoline engine where the job of the oil is to lubricate, a diesel engine uses the oil to run the fuel pump which moves the gas to the injectors. Therefore, a first check when experiencing a rough start is the oil. Manufacturer guidelines are recommended based on factors such as temperatures, driving habits and mileage.

Emissions

The required diesel exhaust after treatment is designed to reduce and remove harmful emissions particulates. Diesel Oxidation Catalyst or DOC is known to be like the catalytic converter found in gas engine vehicles. This system was created to oxidize carbon monoxide, hydrocarbons and diesel particulate matter into CO2 and H2O. This is the first step of the after treatment process which takes place when the exhaust temps increase to around 390 degrees. This is the flow-through filter. 

The next step in the exhaust emissions process is the Diesel Particulate Filter. The exhaust goes through the filter which continues to clean the particles that did not oxidize during the first DOC step. This DPF sometimes requires service as the ash and soot begin to build up in the filter over time to help ensure excessive build up does not occur.

Time for a new engine? Yes, we can do that too.
