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 for confirmation that it is your turbocharger causing the issues. After verification of turbocharger issues contact your nearest Diesel USA Group location for further information about your next step.

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

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.

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.
