Question: Is there a way I can make my turbocharger last longer?

Answer: Yes, through proper maintenance and care of your turbocharger it can and will last. More specifically, keeping your oil and filters changed regularly is crucial to the life of your turbocharger. Schedule an appointment today with our location nearest you to begin a regular maintenance program for your diesel application.

Question: Is it really necessary to let my turbocharger cool down before turning off the engine?

Answer: This is a resounding "YES"! Most turbochargers utilize the oil from your engine for cooling. When turning off your engine before letting your turbocharger cool down you are allowing the opportunity for oil to become trapped in your turbocharger. When this oil cools it can then solidify, causing sludge buildup inside of your turbocharger allowing for pre-mature wear and failure of its internal components.

Question: I'm having problems with my turbocharger, what can I do?

Answer: Consult our handy turbocharger troubleshooting guide or contact any of our locations for confirmation that it is your turbocharger causing the issues. After verification of turbocharger issues we can help you find the correct and best replacement

Question: What information do you need from me to find the correct replacement turbo for my application?

Answer: The easiest way to find the proper replacement for your diesel or automotive application is the part number from your original turbocharger. Once we have that, finding a replacement turbocharger is quick and easy. However if you are unable to provide the O.E. part number we will do our best to match a turbocharger to your application.

Answer: On some part numbers we do ask that you turn in your old turbocharger as a core. On those corresponding part numbers we will inform you before your purchase if a core is needed in return.

Question: Why is the brand name on my turbocharger spelled incorrectly?

Question: If I have only one confirmed "bad injector" should I replace them all?

Answer: No, if proper testing has been performed on all of your injectors and only one has been confirmed as being bad it is okay to just replace the one. However, if testing has only been performed on the injector in question we do suggest that you have the rest of your injectors tested as well. You can contact your nearest Diesel USA Group location to schedule having your injectors tested today.

Question: Can you decode my VIN number?

Answer: No, you will need to consult your application manufacturer for decoded specifics of your VIN number. Most manufacturers are happy to provide you with this information. However, we will still most likely need your original part number for correct replacement.

Question: I put gas in my diesel, what do I do?

Answer: First and foremost you should turn off your diesel application to prevent further damage. Secondly, you will need to drain all the fuel from your application and replace with proper diesel fuel. Last but not least you should use a diesel additive to help avoid any possible damage from existing gasoline in your fuel system. However, these guidelines are only applicable if you've not started your diesel application. If you have started your diesel, the damage caused can vary with how long it was exposed to the gasoline. Have your diesel towed to an authorized diesel service shop for a checkup before continuing to drive.
