Question: My car has a bad odor when I run the heater or air conditioner. My friend said I might need a new cabin air filter – what’s that? Answer: A cabin air filter is a special filter that cleans the air that comes into the passenger compartment – or cabin – of your vehicle. Most new vehicles now have a cabin air filter. A cabin air filter catches dust, pollen, spores and other pollutants before they can get into your cabin. It’s kind of like the filter on your furnace, cleaning the air you breathe inside. As you can imagine, it eventually gets filled up and can even start to get smelly. So – you just have it replaced. Now some are easy to access, and others are tougher to get to. Your service technician will be able to take care of it for you. Your owner’s manual likely has a recommendation for when to replace the cabin air filter. If you live and drive where there is a lot of dust, pollen or pollution, the filter will fill up quicker. Of course, if you’re getting a bad odor bring it to the attention of your service advisor. Give us a call. Read the original article on the NAPA website.

It’s just common sense that your vehicle will drive better if all the wheels are lined up with each other and the road the way the engineers intended. When they’re not, that is called being out of alignment. Here are some signs that your alignment has problems. • Your steering wheel isn’t straight when your vehicle goes straight down a straight road. This one’s pretty easy to notice. If your vehicle’s logo on the wheel is tilted, that’s probably not the way designers wanted it to be. Bring it in and have us check it out. • Your steering wheel is vibrating on a smooth road or when you are accelerating. While this could be caused by several different things, one possibility is misalignment. If your steering wheel is shaking, it should be examined by a trained technician. • Your vehicle is pulling to one side without you wanting it to. Sometimes the configuration of the road will cause it to pull slightly left or right. But if you find yourself constantly correcting course to keep your vehicle headed straight down the road, that’s worth having us look at your alignment. • You’re going through tires like there’s no tomorrow. The tread on your tires should be wearing nice and evenly from the outside to the inside of the tire. If the wear isn’t even, it could be your vehicle needs an alignment. We have equipment designed to quickly and accurately measure your vehicle’s alignment. We can make precise adjustments to make sure you are headed straight where you want to go. Have your alignment checked regularly. It can help prevent more serious problems in the future and make your vehicle drive as beautifully as you remember it used to. Call Frosty's Today!

Your axles are the last link in transferring power from the engine to your wheels. They’re strong parts that last a long time – but they can run into trouble. Axles just wear out over time and need to be replaced. And sometimes axle seals leak, causing the axle to wear out prematurely. Lubricant leaks out, and water and dirt can get in and contaminate the gears. When this happens you might hear strange noises coming from your axle. If you have a rear-wheel drive vehicle, the sound would be at the rear end. If you have a front-wheel drive vehicle, the sound would be up front. Of course, with an all-wheel drive, the sound could come from either front or back. It might be a groaning sound or clunking when turning. There are different kinds of axles, each with their own potential problems. Your service technician knows this and checks for things like leaking seals, torn CV boots, worn axle joints. An inspection will reveal if there are any problems or if a part is nearing failure. When there is a concern with the axle shaft, it will be removed and inspected. If it’s damaged, the shaft will have to be replaced. If the shaft is in good shape, it’ll be cleaned, lubed and reinstalled. Damaged CV boots are replaced as well. It’s important to take care of this work as soon as you become aware of a problem. Waiting only makes the damage worse and more expensive to repair later. If the axle fails completely, it could lock up. This could severely damage other things like your transmission – very expensive. It could also contribute to an accident, which nobody wants. Taking care of your axles when they need it saves money in the long run, and helps keep you safely on the road. Give us a call

We rely on our brakes to safely slow and stop our vehicles. You’ve probably had the experience where you’ve slammed on your brakes and started to skid. When your wheels are locked up, you are just sliding over the road. And if the road is wet or slick or covered with gravel – you really get out of control. Steering is next to impossible. That is why anti-lock brake systems (ABS) were invented: to help you maintain control in extreme stopping conditions. As mentioned, control is lost when your wheels lock up. ABS keeps your brakes from locking – helping you stop while maintaining your ability to steer. Sensors on each wheel equipped with ABS monitor wheel spin and compare it with vehicle speed sensors. When you are pressing on the brakes, still traveling forward but your wheels are not turning, the ABS system steps in and modulates the brakes. They ABS quickly “pumps” the brakes, not allowing the wheels to lock up while still applying braking pressure. This is all done automatically without any intervention on your part. You will feel a pulsation through the brake pedal and will hear a clunking as the brakes are rapidly being applied and released over and over again. The first time this happens to you, you may be surprised and think something is wrong. Well, it isn’t – so just keep your foot on the brake and allow the ABS to do its thing. In fact, remember the 3 S’s of anti-lock brakes: Stomp, Stay and Steer. Stomp on the brakes, stay on the pedal and steer as needed. When you first start your vehicle, the ABS does a quick self-check to make sure everything is OK. The ABS warning light will briefly illuminate with all of the other warning lights on your dashboard and then go out. If the system detects a fault, the ABS light will come on and stay on. Definitely take your vehicle to Frosty Auto Clinic for a check if the ABS warning light is on. Proper brake system service from Frosty Auto Clinic is the best way to protect your ABS. Replacing brake fluid that is depleted and/or contaminated will help preserve proper ABS operation and protect it against corrosion. Ask your Frosty Auto Clinic service advisor if it’s time for a braking system inspection or service.
