An exhaust system is comprised of several different parts. Each one of these parts plays an integral role in the operation and safety of your vehicle. For example, the catalytic converter is a crucial element in converting toxic fumes into environmentally friendly emissions. Because of the importance of each component, exhaust repair in NH is a must at the first signs of damage. This article will take an in-depth look at exhaust leaks, and provide you with the information every driver should know.
Components
As we mentioned, your vehicle exhaust system is made up of several different components, each with its own job. Below is a list of parts and their specific job within the exhaust system:
- Catalytic converter which helps to reduce air pollution by changing harmful carbon monoxide and hydrocarbons into environmentally safe vapors.
- Cylinder heads play a vital role in controlling the combustion process.
- Exhaust manifolds collect the exhaust from multiple cylinders into one pipe, which helps to minimize heat, air, and harmful gases.
- Hangers are extremely important for driving safety. If a vehicle has even one broken hanger, automatic shifting can occur during driving causing a whiplash effect.
- Exhaust joints hold your system in place. As with any element that is tossed around and hit with road debris, joints can leak or obtain cracks that allow leaks to happen.
- Mufflers keep your car running quietly by silencing the combustion process.
- Oxygen Sensors in modern cars sense the amount of oxygen within your exhaust system. This information helps the vehicle’s computer calculate and release the correct amount of fuel for maximum fuel economy.
The dangers of exhaust leaks
Beyond affecting the performance of your vehicle, many safety factors that are a concern with exhaust leaks. Below are just a few of those concerns:
- Carbon Monoxide. The fumes that the exhaust system creates contain carbon monoxide, the odorless killer.
- Interrupted Driving. From vibrating gas pedals to steering wheels and automatic shifting while driving, exhaust system leaks and damages can create a dangerous driving experience for yourself and others.

Now that you’ve prepared your vehicle with the proper tires for the winter months of New England, it’s time to look at another critical element. Elements like your brakes are also imperative to driving safely in the winter. Lucky for you, your favorite auto mechanic, RK Auto Repair, offers brake service in Nashua and surrounding towns to keep you and your family safe this winter. Here’s what you can expect when having a full brake service done with our team.
Inspection
A must for safe driving, breaks should undergo an inspection at least every six months. This is the same timeframe for a tire rotation which takes care of two routine maintenance requirements at once. When the tires are removed, your mechanic will be able to inspect and check the following items:
- Brake fluid
- Brake lines and hoses
- Disc brakes: brake pads, brake rotor, caliper
- Drum brakes: parking brake, brake shoes, rotor, cylinders, springs
- Brake pedal compression
- Wheel bearings and seals
- Springs
- Cylinders and cables
Although there can be several other elements depending on the braking system of the vehicle, this list provides you with the general idea of what to expect.
Repair
While the inspection is underway, if there’s an issue with a specific part that can be repaired we’ll do so with your permission. Components such as the calipers can be repaired with the proper amount of expertise. However, sometimes it’s cheaper to replace than repair. The decision will come down to the amount of repair needed and the labor involved. Because everyone is family here at RK Auto, you can have confidence and trust in our opinions and recommendations.
Replace
Although we’ll try to repair the components that we can, sometimes this is not possible. There are certain parts within your braking system that are better replaced than repaired. Items such as disc brake rotors, brake hoses, and wheel bearings are just a few of these. Furthermore, when choosing whether to repair or place, items such as the material and the amount of labor involved are two of the main considerations. If the piece will require a labor intensive repair, it may be more cost-efficient to replace it.

When it’s time to hit the road, it is essential that your vehicle be well-equipped for the harsh conditions. RK Auto Repair can fit your vehicle with a set of winter tires in Nashua to help keep you and your family as safe and secure as possible once the snow and ice settle in.
The difference
Winter tires and everyday tires are different for several different reasons. The reason winter tires are an essential feature to New England driving is the fact that are made from different rubber than all-season tires. This specially designed rubber provide winter tires with a more effective performance once the road temperatures drop.
The benefits
Additionally, winter tires are equipped with optimized tread. This allows the vehicle to have a better grip on the road. Thus, preventing or minimizing slipping.
The optimized thread also provides drivers a faster breaking experience. In fact, winter tires shorten braking distances up to 30 percent regardless if the roads are wet or dry, slushy or icy. As you can guess, this features will significantly decrease your chances of being involved in an accident.

Regardless if your car is fitted with anti-lock brakes all-wheel drive, or nether, winter tires should be used during the cold season. The professionals at RK Auto can help you with all aspects of selecting, inspecting, repairing, and installing winter tires in Nashua.

Although many people rely on their trusted mechanic for the details of their vehicles, it’s good to know the basics behind the workings. Here in Nashua, brakes are one of the most common reasons to bring your car in for service. From potholes to extreme heat, New England weather provides all the elements your vehicle needs to fall apart. However, with a basic understanding of your braking system and regular maintenance, you can save yourself hundreds in potential vehicle repair.
Hydraulic
The most common system for vehicles and motorcycles is the hydraulic braking system. This system works in combination with braking fluid and other components of your car. With the transfer of energy, the brakes enable an object to stop; typically a rotating axel.
In order to maintain optimal functioning in your braking system, routine maintenance is crucial. During your routine check, your braking system will be inspected by a licensed mechanic. Several items will be checked out by your mechanic. These include:
- Brake Fluid Levels
- Fluid Flush and Replacement
- Wear and Tear of Brake Pads and Rotors
- Bleed the Brake Lines
- Inspect Brake System Components
Regenerative
Often seen in hybrid and electric vehicles, regenerative braking systems are an innovative way of thinking. Essentially, breaking is an inevitable part of driving and a waste of energy. The built-up heat dissipates instead of being used as energy. Thus, engineers have created a new type of system that converts the energy into electricity, helping to recharge the vehicle’s battery. A more efficient system, regenerative brakes will also provide owners with a longer lifespan.
Servo
Otherwise known as vacuum or vacuum-assisted braking, servo braking lessens the wear on the components of your vehicle. Power assistance is used to reduce the human effort. In other words, the required pressure need to operate the brake pedal is lessened. Thus, you can expect a longer life on elements such as your brake pads and rotors.
If your brakes have you questioning their integrity, our ASE Certified mechanics will thoroughly inspect your braking system to ensure optimal performance and safety. To schedule your appointment, contact the team at RK Auto Repair today.


Many vehicle enthusiasts look forward to this time of year in New England. Summer cars are out, tops are off, and updates are happening. One of the biggest trends we see at RK Auto is the changing of tires. With winter conditions far behind us, winter tires are off, and summer tires in Nashua and surrounding areas keep vehicles looking their best during the warmer months. However, before running out and switching your tires, there are a few considerations to keep in mind.
Manufacturer’s Speed Rating
One of the most important factors to take into consideration when choosing tires is the speed rating. Ratings will let the driver know the maximum recommend speed that a tire can be safely driven. For many, this element is not an issue. However, most summer tires are made for high-performance vehicles and provide increased speed and agility. If racing is a seasonal pastime, be sure to watch the rating levels.
Driving Conditions
Summer tires are categorized seasonally for safety reasons. More specifically, they are not designed to function in cold weather. This type of tire can generally handle three out of the four seasons. Once the cold air sets in, the rubber of the tire can harden creating undesirable driving conditions. Their optimal functionality can be maintained in temperatures over 44 degrees Fahrenheit. However, when rain is the consideration, summer tires perform better than all-wheel tires. Helping to control hydroplaning at higher speeds with increased traction, summer tires may keep drivers safer during the drizzly spring months.
Often, summer tires can be thought of as “every day” tires because of the versatility throughout many of the New England seasons. However, keeping in mind their restrictions is extremely important. Furthermore, summer tires in Nashua, for many, mean low profile or high-performance tires. This type of tire falls into a separate category with entirely different functionalities and precautions.

Voted the best mechanic in the area, the team at RK Auto is fully licensed and insured.

One thing you can count on is that your vehicle will not be shy when it comes to letting you know it needs exhaust repair. As one of the most worked components in your vehicle, the exhaust manifold is the most common area in need of repair. The constant heating and cooling creates expansion and contraction in the manifold. Thus, manifolds have been known to commonly crack over time. However, there are several components when dealing with an exhaust system. RK Auto Repair knows exhaust repair in NH. Below, RK Auto has created a list of four tell-tale signs that your vehicle’s exhaust system requires a little TLC.
Rumbles and Hissing
One of the most noticeable signs that you may need exhaust repair services is the presence of unusual sounds. Loud rumbles or hissing are commonly heard by vehicle owners if there is a leak in the manifold. This type of leak can increase engine volume. Although other components of the exhaust system can lead to increased volume, the manifold tends to be the most common.
Foul Smelling Fumes
Another component of your exhaust system is the catalytic converter. This component helps to transform harmful pollutant gases into less harmful ones. Thus, if the converter goes, you may be sitting in some pretty foul smelling fumes on your ride across town. Often associated with a sulfur smell, when a catalytic converter goes, you can be sure you’ll know. Another sign of a failed converter could be rattling noises from under the vehicle.
Decrease in Fuel Efficiency
Perhaps you’re finding yourself at the gas pump more often than usual. A leaky exhaust system makes it harder for your engine to power the vehicle. Thus, you will find a decrease in fuel efficiency may occur. Be sure to pay special attention to your vehicle’s performance when you step on the gas pedal. If you notice any type of lag, it may be time to call your local auto repair shop.
Loud Noises
Even if you’ve never heard of the above-mentioned components, chances are you know what a muffler is. As part of the exhaust system, your vehicle’s muffler helps to reduce emissions and noise. Cracks in your muffler can become a serious concern as you and your passengers may no longer be protected from hazardous fumes such as carbon monoxide.

Axle-back
One of the quickest exhaust upgrades you can choose is the axel-back. This type of exhaust replaces the stock system from the rear axle to the muffler. Hence the name. Requiring no cutting of stock components, the typical turnaround time on installation is less than an hour. The driver will notice a small change in power. The most noticeable difference will be the sound your vehicle puts out. Overall, the axle-back has the least effect on performance and fuel economy enhancements.
Cat-back
A step up from the axel-back system, a cat-back exhaust will provide drivers with more noticeable enhancements. This custom exhaust replaces stock components from the behind the catalytic converter to the muffler. The replacement provides a fairly decent increase on the original performance and fuel economy. Some upgrades can make a vehicle noncompliant with smog emissions. One of the best features of a cat-back system is that your emissions will remain the same.
Header-back
The header-back system is a complete replacement of stock components with aftermarket components. If your goal is to have the most significant impact on performance and fuel economy, this is the upgrade for you. That being said, not all vehicles are ready for this type of upgrade. In most cases, preparations need to made to the vehicle before installation can occur.

The saying goes “You can’t reinvent the wheel.” As far as car parts go, the tires are the only part you won’t get anywhere without. Sure an engine, accelerator, exhaust, and every other part is important, but without those, you could still roll. You depend on your tires in Nashua to get you where you’re going, but how often do you check them? Every piece of a car has a shelf, life including your tires in Nashua. With proper care and maintenance, you can extend that shelf life considerably. Here are some ways you can make the most of your tires.
Tire Pressure
How long your tires last relies heavily on the tire pressure. Without the proper inflation pressure, your tires can’t perform the way they’re supposed to. While underinflated tires are more common, overinflated tires are just as hazardous to the lifespan of your tires. Not every car has the same required tire pressure. Luckily you can find the proper inflation pressure listed along the side of your tire.
Alignment
For your car’s wheels to wear evenly, you need to maintain proper alignment. On top of your tires, having your wheels out of alignment can signify other mechanical problems. The last thing you need is a wonky ride.
Remember to Rotate
Depending on which position on your vehicle the tire occupies, different forces are applied. Without rotating your tires, they will begin to wear unevenly, putting some at a higher risk for damage. The only way to keep an even wear is to rotate your tires. Mechanics recommend rotating your tires every 5000 miles.
Balance is Key
If you’ve ever noticed a vibration while driving, it could be a sign that your balance is off. On top of being annoying, an unequal balance can contribute to tire wear. The more factors that wear away at your tires, the shorter their lifespan becomes.
When it comes to tires in Nashua, every driver is responsible for taking care of them. Knowing the factors that can lead to worn out tires is the first step to preventing damage. The better care you take of your tires, the longer they will last you. If you are in need of new tires, contact RK Auto or visit us online.
