Vehicle Maintenance FAQs

General

Maintenance

Why is an car maintenance important?

The simple answer: to help keep your car running newer, longer. By letting us perform routine maintenance, you’ll help spare bigger car trouble.

Lapsing maintenance on your car’s vital fluid exchanges, dirty filters, fussy belts and old spark plugs can lead to bigger problems like busted-up radiators, slipping gear shifts and engine failure. That’s why routine maintenance is key to vehicle longevity. Maintenance you think you can “let go” in the short term can often be an “oh, no!” down the road.

Your manufacturer has designed a maintenance schedule (found in your owner’s manual) around the specific makeup of your particular vehicle. Follow this schedule and chances are your vehicle will deliver optimal performance as you rack up the miles, help your parts last longer and save you some dough on more expensive replacement parts.

Bulb Replacement

How many different bulbs are there in the average vehicle?

More than most Christmas trees. For real. And it’s not just fog lights, turn signals and rear, mirror and side bulbs you’ll have to contend with. Bulbs are everywhere, especially on vehicles with fancy LED bulbs: they can feature over 100 bulbs in the rear of the vehicle alone. These bulbs will last varying amounts of time, so inspect your vehicle regularly to make sure no crucial rear or front lights are out.

Wiper Blade Replacement

How long do wiper blades generally last?

Wiper longevity depends on where you live. Heat really wears on those rubber windshield squeegees; therefore, if you live in a hot climate, wipers will inevitably require more frequent replacement. Accordingly, if you use your wipers often – and live in a rainy, snowy or icy neck of the country – expect a shortened blade life.

A general wiper blade rule of thumb: if wipers smear water or snow and obstruct your view when they swoosh by, it’s time for new blades.

Worn blades? Get them replaced at your nearest Firestone Complete Auto Care.

Fluids

Coolant Fluid Exchange

What is the job of coolant fluid?

It’s the working fluid for the cooling system, which controls the operational condition of the engine. Because the engine is a controlled explosion, it needs to be kept between a specific temperature range for optimal performance. Whether it’s cold or hot outside, the cooling fluid allows the cooling system (including the radiator) to keep the engine and radiator at just the right temperature. Think of this way: coolant fluid is a warm blanket in the winter and a misting fan in the summer.

How does coolant fluid flow through the system?

Transmission Fluid Exchange

What is the best day to get a fluid exchange?

So, you want to know the industry’s best kept secret, eh? Well, from our experience, Tuesdays and Wednesdays are usually the best days to stop into Firestone Complete Auto Care. Now that we’ve said that, we can’t guarantee those will not become the most popular days as a result. But you asked. And now the cat is out of the bag. See you Tuesday or Wednesday.

We even have extended evening hours and most stores are open Sundays. Schedule an oil change for any day of the week.

Fuel System Cleaning

What does a fuel injector do?

Talk about important. A fuel injector is crucial to making your engine and car GO. It takes fuel from the fuel pump and breaks it into incredibly small droplets that easily mix with air to allow a more complete internal combustion in the engine. Designed and calibrated for the vehicle it handles, a fuel injector makes sure the fuel can be burned more easily and completely.

Filters

What does an air filter, cabin air filter or fuel filter do?

All auto filters are designed to prevent harmful debris from entering any parts where air and fluid flows, including your engine, radiator, fuel lines and more. Once a filter is no longer performing its intended function, decreased performance – even engine damage – can result.

You’ve been reaping the benefits of filters your entire life. If you’ve ever used a furnace or air conditioning system at home, you’ve had to replace a filter from time to time. If you haven’t, well, you might want to go and check those out too. You can send us a thank you letter later – if you want.

In the meantime, here’s what each automotive filter does:

Air filter: Prevents harmful debris, dirt and contaminants from entering your engine.

Cabin filter: An implementation that began appearing in vehicles in 2002, it prevents dust, pollen, dirt and other pollutants from entering your car through your A/C and heat vents.

Fuel Filter: Keeps dirt, debris and contaminants from clogging your fuel lines and causing erratic, unstable fuel performance and reduced fuel economy.

Belt Replacements

What does a serpentine belt do?

Well, it won’t keep your pants up, but does transport power to your vital automotive components. The serpentine belt is one long, snaking, winding belt that keeps your alternator, power steering pump, air conditioning and - in some cases - your water pump running smoothly and effectively.

Didn’t cars used to have more than one belt?

Spark Plug Replacement

What do spark plugs do?

Think of spark plugs as the tiniest bolt of lighting. Small but mighty, the spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. By putting the engine’s pistons in motion, your car can power up, stay powered up and produce a smooth burn of the compressed air-fuel mixture. Mind you, spark plugs like it hot: they withstand extreme heat and pressure within your cylinders and are built to burn off deposits from fuel additives or other contaminants.

What does it mean for you?

Well, without a spark, your car won’t start – or go anywhere. And because spark plug health is directly linked to engine performance, it stands to reason weak or bad spark plugs lead to problems, be it issues with cold-starting or misfires during acceleration. Besides – without healthy ones – your ride can’t sustain maximum power, and your vehicle can see a drop in fuel economy. Now, nobody wants that.
