Boulder Auto Repair

Your car might have an alignment problem if: it drifts or pulls to one side, your steering wheel is off center, you have uneven tire wear or your car doesn’t feel like it handles right. 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 object are great ways to knock your car out of alignment. Then one or more of your wheels starts pulling in a slightly different direction and the problems begin. Driving for an extended time when you’re out of alignment causes your tires to wear unevenly and excessively. This can be dangerous and expensive. You’ll have to replace your tires sooner, but even worse – you may cause premature wear to your suspension system, which can be really expensive. The front wheel alignment is adjustable on all vehicles, and the back wheels are also adjustable on some cars. The adjustment can go three different ... read more

Welcome to the John’s Auto Care automotive blog. Today, let’s talk about the effect of tire tread depth on braking. When talking about stopping power, most Boulder and Boulder drivers tend to focus on our brakes. But our tires are where the rubber meets the road. So having good brakes isn’t enough. Safe Boulder drivers need to have tires with enough traction to translate braking power into stopping power.Let’s focus on stopping in wet Boulder conditions. In order for a tire to have good contact with the road, it has to move the water out of the way. If it can’t move the water, the tire will actually ride on top of a thin film of water. That’s called hydroplaning. If it’s really bad, Boulder motorists can actually spin out of control – endangering themselves and the other drivers around them. At best, you won’t stop as fast.So how does ... read more

A lot of gas is wasted in the Louisville area by dirty fuel delivery systems. Let’s start at the tank. The gas tank gathers dirt, rust and sediment over the years. That’s why there’s a fuel filter to clean the fuel after it leaves the tank. A dirty filter will rob the engine of the clean gas it needs to run efficiently. The fuel intake components get coated with gum and varnish over time. This results in fuel being delivered inefficiently and some of that gunk getting into the engine. A fuel system service at John’s Auto Care will leave your intake as clean as a whistle. The big fuel thief is dirty fuel injectors. They deliver fuel to the engine at a specified pressure and in a particular spray pattern. When they’re clogged, the fuel doesn’t get ato ... read more
