A diesel truck – especially one with a Duramax engine – is a big investment, and you want to take care of it. So, if you get a scan and it comes back with a trouble code, it pays to know what’s going on under the hood.

One of the most common DTCs (diagnostic trouble codes) for Duramax trucks is P003A. Here’s what you need to know if you encounter it, and the steps you should follow to fix it

Can’t afford that brand-new, top-of-the-line diesel truck? We know how tempting it can be, and how hard it is to say no. But that doesn’t mean you can’t find something great out there that’s new to you. When you find that perfect vehicle that’s just within your budget, driving it home can feel like you just won the lottery.
 
But as with any lottery winning, you have to be careful that you don’t get more trouble than you anticipated. It’s no different with a used diesel vehicle – you don’t know if the engine looks good on the inside, if the parts are clean, or if the fluids are topped up.

Assuming you already know what to look for when buying a diesel truck... here are the top 4 things to do AFTER you buy a used diesel truck, to make sure you stay on the road and moving fast.
