Boulder Auto Repair

Hello, welcome to John’s Auto Care. Today’s focus is batteries. It seems like everything in Boulder runs on batteries. Of course, the batteries we’re most concerned with here at John’s Auto Care are those in our customer’s vehicles. Just like the batteries in our smoke detectors or TV remote, car batteries wear out and need to be replaced. There are a couple of things Boulder drivers should know when looking for a new battery. Look for two measurements that come into play: cold cranking amps and reserve capacity. Let’s start with cold cranking amps. This can be thought of as the power output used to start a cold family car engine. The number of cold cranking amps you need depends on your vehicle and where you live in CO, specifically how cold it is. (Many CO auto owners have first-hand experience trying to start their car on a cold winter morning.) The two fac ... read more

Eldorado Springs auto owners may have an alignment problem if their car drifts or pulls to one side, the steering wheel’s off center, they notice uneven tire wear or the car doesn’t feel like it handles right as they drive down Boulder, CO streets and highways. When all of a vehicle’s wheels are lined up exactly with each other, your wheels are in alignment. Running into potholes, smacking a curb or other objects around Boulder, CO are great ways for Boulder drivers to knock their car out of alignment. Then one or more of your wheels starts pulling in a slightly different direction and the problems begin.The team at John’s Auto Care in Boulder wants you to know that driving for an extended time when your car is out of alignment causes your tires to wear unevenly and excessively.

Our vehicles are not massage chairs. While we may enjoy a good vibration in an overstuffed recliner, us Boulder auto owners generally want as smooth a ride as possible in our vehicles. One way to achieve this is to keep a vehicle’s wheels in balance.When a tire is mounted onto a wheel, it is usually out of balance. This means that as the wheel spins, there is a slight wobble to the path of the tire. For best handling performance and safety on the road, Boulder drivers want to minimize this wobble as much as possible. So we balance our tires. To balance a tire, your cheerful John’s Auto Care technician spins it on a machine or drum to determine where it is off-balance. He then attaches weights that counter-balance the uneven weight. Most Boulder drivers are surprised at how much balancing improves the smoothness of their ride.High-quality tires generally hold their balance well. But over time, wear and tear take their toll and tires can become unbalanced. B ... read more

Power steering is standard on nearly every car and truck in Boulder, CO these days. Now there are some exotic, new types of power steering systems, but for the most part, the general setup is a pump that’s driven by a belt powered by the engine.The pump generates power that assists motorists as they steer their family car around Boulder, CO. Power steering systems use hoses to move pressurized fluid back and forth. These hoses can develop leaks so it’s a good idea to have your Boulder technician inspect them at every oil change. A check of the power steering fluid level is on the list for every full service oil change at John’s Auto Care because low fluid can damage the power steering pump. And the fluid needs to be compatible with the hoses and seals, so it’s critical to use the correct type –just ask your technician at John’s Auto Care. In addition to providing boost, the fluid cleans, co ... read more

All modern Boulder vehicles come with fuel injection systems, so it’s a topic Eldorado Springs auto owners need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount, at the right time; to be mixed with air and burned in the engine. So how many fuel injectors does your car have? There’s one for each cylinder. So four, six or eight for most folks in Boulder, CO. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty high-tech. John’s Auto Care can help Eldorado Springs auto owners with a fuel injector cleaning service. What’s the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It’s important that the fuel is sprayed in a particular pattern a ... read more
