NH State Inspection

In the great state of New Hampshire we are required to register and inspect our motor vehicles. Registration fees go to your local city or town and the state. The inspection of your motor vehicle must be performed by a state licensed inspection facility like Bob & Sons Automotive.

A question we hear regularly at Bob & Sons Automotive is, “I’m new to the area, why does the state require me to have an inspection every year.” We love educating our customers in all things auto related, so this is right up our alley. In order for the state to regulate the safety of our roads, they need a mechanism that can measure the safety of the vehicles on those state roads. Every year we must inspect the safety and emission related components on these vehicles to be sure we are in compliance and driving safe vehicles.

There are two portions to the NH Safety and Emission Inspection. The first is safety. Motor vehicles’ parts wear out. After time suspension parts become worn out and need replacing, brake parts are past their usable life, wipers do not clear the windshield anymore, sometimes an exterior directional bulb won’t work. These are all instances where customers need to be alerted to the status of the safety of their vehicle.

The emissions portion of the State Inspection deals with the On-Board Diagnostics component. OBD systems are in vehicles that are model year 1996 and newer. This portion of the test deals with emission controls components and is tested by a state mandated computer.

The next question we get is when do I need to have my inspection performed? In New Hampshire we are required to register and inspect our vehicles in our birth month. For example: If your birthday is April 5, 1984, then you need to have your vehicle inspected in the month of April. In this scenario the state says you must have a new registration and inspection performed by May 10. The state gives a ten (10) day grace period after the vehicle owner’s birth month.

The NH Safety and Emission Inspection allows the state to try and keep unsafe vehicles off our streets. If you have any other questions regarding registering and/or inspecting your motor vehicle please visit the State of NH website: https://www.nh.gov/safety/divisions/dmv/registration/inspections-emissions/index.htm

Why you should hand torque?

Auto Shop in Manchester

If you have been in business as long as we have at Bob and Sons Automotive, you can honestly say “We’ve heard it all”. When customers ask us, “Why do you hand torque every vehicle you work on”, we know just how to answer.

Many auto repair shops will use a torque stick to torque the lug nuts on a customer’s vehicle. Each torque stick has a range that it will torque to and hopefully flexes or stops torqueing at that level. If not, you could have over torqued wheel lug nuts.

Some shops won’t even use torque sticks and will rely on their “years of experience to know when to stop the air gun”. This method is not recommended for a number of reasons. What happens if they have a new hire who doesn’t have the expertise to be able to listen or feel for the right torque? What happens if the setting on the air gun is turned up or down and no one checks the setting? Yup, you guessed it, either under torqued or over torqued wheels.

What happens if the air compressor in the shop trips and shuts itself off? No one realized that the shop air wasn’t at the proper level, no one double checked the torque on those tires and poof you have a serious problem shortly thereafter.

The wheels on our vehicles are what contacts the road, if we don’t have the lug nuts properly torqued on our vehicles then we are driving unsafely. This is the reason we, at Bob and Sons Automotive, hand torque every wheel that we remove. This is easy and cheap insurance for us and our customers that the job was done right and everyone operating or traveling in that vehicle will ride safely.

Why you should change your air filter

Auto Shop in Manchester

At Bob & Sons Automotive we check the engine air filter on every vehicle we see because we know how important it is for the engine in your vehicle to breathe properly.

Imagine you are a disciplined, powerful, long-distance runner. Imagine you take great care of yourself in staying fit, eating right, and exercising regularly. Then imagine you’re on a long stretch of road and you want to open up the throttle and go fast, just then you start to feel a restriction in your airway and you can’t get the oxygen you need to get optimal performance. Can you picture this?

This is what it feels like for your engine when it can’t get the air it needs to perform the way it was intended to. When air filters are not replaced, they get clogged with dirt and debris.

There are many benefits for your vehicle when replacing your air filter regularly. Those benefits include better gas mileage, reduced emissions, improved acceleration, increased engine life and overall improved drivability.

For each gallon of fuel burned, the engine uses up to 10,000 gallons of air; this is why it is easy to understand how vital a clean air filter is to your motor vehicle.

Replacing your vehicle’s engine air filter is one of the most cost-effective ways to maintain your vehicle’s high performance.

Vehicle Transmission Maintenance

At Bob & Sons Auto we are all about preventative maintenance.  We believe that if we are proactive about maintenance on our customer’s vehicles, then those said vehicles will break down less often.  Vehicle maintenance services are much more economical than vehicle break down repairs.

One of those vehicle maintenance services that we love to perform at Bob & Sons Auto involves replacing the transmission fluid.  Transmission fluid is a slippery liquid that acts as a lubricant for all of the moving parts inside your transmission. In an automatic transmission, this fluid also serves as a coolant and a viscous fluid that transmits power from the engine to the transmission.

When should I do this service?

Manual transmission: Most manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles. Under heavy-duty use, some manufacturers suggest changing transmission fluid every 15,000 miles.

Automatic transmission: Service intervals for an automatic transmission vary from every 30,000 miles … to never. The typical service interval is 40,000 to 80,000 miles. Changing it more often does no harm.

Why do I have to do this?

Fluid contamination and heat.  Contamination occurs over time as the synchronizers, bearings and gears in the transmission wear out. The resulting metal particles then float around in the lubricant.  Oil with microscopic particles of metal in it does not lubricate as well as clean oil. So if these contaminants are not drained out, they will shorten the life of your transmission.  Heat is the other major factor in the need to replace transmission fluid.  Heat degrades oil after so much time.  This same thing happens with transmission fluid.

What happens if I don’t do this?

If you decide not to replace the fluid inside your transmission, your car will have metal pieces floating around inside your transmission.  Or over time the fluid will degrade and you will have burnt, worn out fluid.  At some point the transmission won’t be able to lubricate itself properly and this will lead to a break down which could be very costly.

Transmissions are one of the costlier items on a vehicle to replace.  Replacing the fluid at maintenance intervals will lessen the chance of that costly item needing to ever be replaced.  At Bob & Sons Auto we check the condition of the transmission fluid on every car that we see in hopes we can help our customers be proactive and avoid an expensive transmission replacement.

Why our mechanics recommend pre-buy inspections…

Pre-buyWhen people buy a house – it’s considered an investment. You do the necessary legwork up front such as home inspections and appraisals to understand the longevity the home has, and to take comfort knowing the home is safe. This approach can easily be translated to the automotive world. Too often, consumers make a big investment in vehicles without doing the proper research. Private sales through things such as social media sites and roadside signs, or through used car dealerships can’t necessarily be trusted. Unless you have a skilled eye for finding problems on cars or automotive repair training – then you may have no idea what you’re buying.

We want you and your loved ones to feel safe and confident in your used car purchase – even if you don’t purchase your vehicle from us (Even though we have great vehicles for sale). We offer a pre-buy inspection for those who want peace of mind. We encourage those buying a secondhand vehicle (without a reputable dealer warranty), to have a pre-buy inspection and second opinion before investing your money into a vehicle. This approach allows you to make an informed decision on going forward with purchasing the car, or provide with the tools to make the decision if you want to make the investment.

During our pre-buy inspection, we check all the same items that would be checked for a New Hampshire state inspection and beyond. We also check the exterior for scratches, dents, rust, and possible signs of previous accidents. On the interior, we review lights, radio, GPS/navigation, mirror operation, heated/cooled seat mechanics, power seat mechanics, seat belt safety, HVAC system, cabin air filters, and run diagnostics. We test drive the vehicle looking for shaking, grinding, alignment or steering issues, wheel bearing noises and beyond. Under the hood, our mechanics ensure to check all fluids for condition and quality. Lastly, under the vehicle we double check for rust in rockers, body, frame, brake lines, fuel tank and/or straps. This includes a full inspection on tires, steering, suspension, exhaust, and brake parts.
An educated decision whether to buy a vehicle gives you control over your investment. If you have questions or would like to schedule a pre-buy inspection – call us at 603.623.9295 or schedule an appointment.
