For some, winter means skiing, snowmobiling and other cold-weather fun. For your vehicle, however, winter can bring a long list of problems. These issues do not fix themselves over time and, when left unnoticed, can lead to costly repairs and, eventually, a vehicle that is no longer safe or roadworthy. To help prevent that, here are some of the most critical components affected by winter driving.

When it comes to automotive care, there is only so much an owner can do to keep a vehicle in top shape. For those living in climates where roads are salted to improve winter traction, some damage is simply unavoidable. Over time, salt and moisture work their way into fasteners and seams, turning routine garage work into frustration, like when a 12 mm bolt head suddenly rounds, or worse, snaps off. At the same time, watching once-clean fender lines, rocker panels, and other salt-spray zones begin the process of rust deterioration is more than cosmetic; it’s heartbreaking, wallet-busting, and a reminder that spring and summer better be perfect to offset the harsh winters.

It never fails. The forecast calls for cold weather, and the next morning, you walk out to your car, reminding yourself why you wish you were on a beach somewhere else, only to turn the key and get a few slow cranks, followed by an electronic stutter as a Christmas tree of warning lights illuminates the dashboard. The battery that worked just fine before the cold set in is suddenly dead, and now you’re late for work. While it’s easy to blame Murphy’s Law or bad luck, the real reasons behind winter battery failure are far more scientific. 

Vehicle: 2017 Ford F550, 4WD, Super Duty, V8-6.7L DSL Turbo

Mileage: 140,598

Problem: This vehicle was brought to the shop because the malfunction indicator light (MIL) was on, and the engine kept stalling intermittently. Also, the engine occasionally took a long time to start.

Vehicle: 2010 Toyota Tundra, 2WD, V8-5.7L (3UR-FE), Automatic Transmission/Transaxle

Mileage: 187,009 miles

Problem: The owner’s concern was that the transmission would shift into fourth gear but not overdrive. The malfunction indicator light (MIL) and the traction control lights were on.

There are few pastimes that capture American culture quite like a car show. I spent my youth immersed in car shows and racing events, with a father who always had a project in the driveway (something I naturally inherited). But don’t let that make you think you wouldn’t be welcome if you're not a traditional “car person.” Car shows are about more than just the cars; they’re a way for owners to showcase their finest achievements and builds. Since COVID has passed, destination-style, weeklong car shows have grown in popularity, celebrating not just the rides themselves but the culture and camaraderie that surround them.

I’ve often said that SEMA is the Super Bowl of the automotive industry. While there are valid arguments both for and against that comparison, one fact remains: every year, SEMA draws more than 2,200 exhibitors and approximately 160,000 visitors - making it one of the top three events held at the Las Vegas Convention Center. That alone is nothing short of remarkable for anyone who lives and breathes automotive culture.

If you spend enough time reading automotive care magazines, you will start to see the same fall maintenance tips over and over: check your tire pressure, inspect your brake rotors, inspect fluid levels, and maybe even check the two-digit month and year on your battery to see if it is nearing the end of its life (typically 3-5 years on average). While these are all great suggestions to work into your maintenance schedule, they are a bit redundant. We thought a new list with some oddball ideas might be a better fit.

Let’s face it, diagnosing automotive electrical, drivability or emissions-related issues can be a bit challenging. But a DIYer or automotive student armed with good diagnostic skills, a scan tool and reliable diagnostic and repair information can identify and fix most of those issues.

Diagnostic skills will develop naturally with practical experience so in this article, our focus will be on building a good fundamental knowledge of on-board diagnostics (OBD), scan tool operation, diagnostic trouble codes (DTCs) and what to do with DTCs once you’ve found them.

Like most electronic devices, scan tool technology is evolving at a rapid pace and the product options seem almost endless. So, how do you know which one is right for you? The answer depends on the features and functionality you want, your budget, and your eagerness to take your diagnostic skills to the next level. In this article, we will explore various kinds of scan tools, pricing and what to look for when choosing the right scan tool for your needs.

A good battery shouldn’t lose its charge overnight or even after sitting a few days. If it does, the problem may be the battery can no longer hold a charge, the alternator isn’t working, or the battery terminals are corroded. But if the terminals are clean and tight, the battery is fairly new and the charging system warning light is not on, there’s probably an electrical component or wiring issue causing an electrical drain (or parasitic draw) on the battery. There are a couple of ways to pinpoint which circuit, component or module is causing the battery to discharge.

Diagnosing electrical problems in your car, truck, or SUV can be challenging, but there are several signs that can help you identify potential issues. Here are some common indicators of electrical system problems...

Your vehicle's onboard diagnostic system can generate numerous diagnostic trouble codes (DTCs) to identify repair issues that require attention. While the specific codes may vary depending on the make, model, and year of the vehicle, there are some common DTCs that tend to occur across different vehicles. ALLDATAdiy makes it easy to interpret DTCs and determine your best course of action, based on the latest manufacturer information.

Following original equipment manufacturer (OEM) repair procedures is crucial when working on a vehicle for several reasons...

Whether you bought your vehicle new or used, it’s a good idea to become familiar with the noises it makes when everything is operating properly so that you’ll know when something sounds abnormal.
