Boulder Auto Repair

If you’ve ever heard a squealing sound under your family car hood, chances are it was your serpentine belt. Your serpentine belt is a long belt that’s driven by your engine. It winds around several accessories that power important automotive systems in your family car. Let’s go over them.First, the serpentine belt drives your air conditioning system. It spins the compressor that makes the cool air that takes the edge off the summer heat in Boulder. More importantly, the belt powers the alternator. The alternator creates electricity that’s used by your family car’s electrical systems and also charges your car battery. Without the alternator, the battery will go dead in a few miles. The serpentine belt may also run the pumps for both the power steering (some are electric) and power brakes (some use vacuum boost). And, on most f ... read more

When I was a kid in Boulder, my dad always made sure he took the cars in for Spring and Fall checkups. I was telling a friend that it’s about time to get into John’s Auto Care for my checkup and he said that he read on the internet that modern cars don’t need seasonal service. My friend is (technically) right about some things, but from a practical standpoint, a seasonal check up still makes sense. Back when my dad was teaching me about how to take care of the family family car, most cars used a different weight of oil in the winter and in the summer. But most of today’s modern engines run the same oil year round. High-tech engines and high-tech motor oils are better able to handle the seasonal changes. Your owner’s manual or Boulder service advisor at John’s Auto Care can tell you the right oil to use. Of course, you’re concerned about the ... read more

Many Boulder car owners have been hearing about technological advances in power steering, specifically, electric power steering. Some very high-end cars have been featuring electric power steering for a few years now. An electric motor directly provides the power assist to make steering easier. Undoubtedly we’ll see much more of this in Boulder as full electric cars and electric hybrids become more common. The vast majority of cars and trucks serviced at John’s Auto Care in Boulder use a hydraulic power boost system. With hydraulics, fluid is pressurized by a pump which actuates a hydraulic cylinder to reduce steering effort. Some of these pumps are powered by an electric motor. Most pumps are powered by the serpentine belt driven by the engine. Power steering fluid has the necessary hydraulic properties and the ability to lubricate the internal parts. The power stee ... read more

North Americans love their cars. And nothing goes with cars better than the road trip. Freedom from daily schedules, new sights and the open road – it’s great! But there’s nothing like car trouble to bring the fun to a grinding halt. Now you can’t always avoid problems, but you can take steps to reduce the probability of getting sidelined on your trip. The first step is to look at your trip plan from your vehicle’s perspective. What kind of roads will you be traveling – winding byways or super-highways? Mountains or plains? What weather conditions are you likely to encounter? How many miles will you travel? How much weight will you be hauling – passengers and luggage? Lugging a trailer or roof top carrier? Will it be dusty? Armed with the answers to these questions, you can start a trip inspection to help you prepare your Boulder vehicle for your big adventure ... read more
