Engine and Exhaust System

Engine Repair
Wheels that are out-of-line (as evidenced by uneven tread wear or vehicle pulling) make the engine work harder, too. Properly maintained tires will last longer, meaning fewer scrap tires have to be disposed. Observe speed limits. Mileage decreases sharply above 60 mph.
Oil Change
One of the simplest ways to determine the condition of your engine is to examine the oil that drains out during an oil change. The oil circulates through much of your engine, so it's a great way to determine the overall health of your car's power plant. Ideally, we want your oil to be darker than when it went in with uniform viscosity and no solid particles. Solid particles are a major concern because they mean that something inside the engine, be it a seal or anything else, is breaking apart. Engines contain a lot of finely balanced mechanisms with only a few micrometers of space for moving parts to clear each other. Any solid particles moving through your engine can cause a massive amount of damage very quickly. At Dow's Automotive Service we perform expert analysis on your oil to make sure that everything is working perfectly within your engine's internals, and we carry the best oils to replace that fluid in your vehicle.

Spark Plug Replacement
Emissions Inspection
Timing Belt/Chain Replacement
Fuel Injection Service/Repair
A fuel injector is an electronically controlled valve that supplies the engine with pressurized fuel. When driving, the oxygen sensors tell the engine if it is getting too much air, which signals the fuel injectors to give the engine spurts of pressurized fuel. Since fuel injectors are small pieces of equipment (and the part that squirts the fuel is even smaller), any little piece of dirt can clog it. A clogged fuel injector will hurt your vehicle's performance. To avoid misfires, poor emission rating, poor performance, and rough idle have the car's fuel injectors cleaned regularly. For professional fuel injection cleaning services, call 603-436-9886 or visit Dow's Automotive Service today.

Transmission and Drivetrain

Transmission Service
Get top-notch auto repair services today at Dow's Automotive Service. From AC repair to transmission services, our goal is to offer expert auto repairs at an affordable price. We are conveniently located near you in Portsmouth. Come by our shop at 909 Islington St or call today to schedule an appointment at 603-436-9886.
Transmission Repair
We know your time is money. Most truck or car maintenance services can be completed while you wait. Many repairs such as AC repair, brakes, and transmission repairs will be performed that day. Straight forward or complicated, our mechanics will get your auto repairs done quickly and get you back on the road right away.
Transmission Fluid Service
Although most manufacturers recommend a transmission flush every 30,000 miles or every two years, some symptoms may indicate that you need a transmission flush sooner. Some of the symptoms that indicate that your car needs a transmission flush sooner are: transmission grinding or strange noises, problems shifting gears, slipping gears, surging of the car, and delay in vehicle movement. Flushing the used fluid from the transmission washes away tiny particles of dirt, clutch material, and metal shavings. For all your transmission flush needs, call 603-436-9886 or visit Dow's Automotive Service today - we are transmission experts.
Clutch Service/Repair
Just like replacing your engine oil, transmission service is part of your routine vehicle maintenance. The service involves removing and examining the pan, cleaning or replacing the screen or filter, cleaning the pan, reinstalling the pan (with a new pan gasket), replacing the old oil with new, and adding an additive package. Adding new fluid restores the holding power between the clutches. This service helps improve lubrication and helps maximize the life of the transmission. For all your transmission repair needs, visit or call Dow's Automotive Service in Portsmouth, NH 03801 today. We offer transmission services, reseal services, and clutch services.

Steering and Suspension

Suspension Service/Repair
Steering Service/Repair
Steering Fluid Service
Power steering fluid is the hydraulic fluid that transmits the power in a steering wheel. Servicing the power steering involves flushing out the old power steering fluid and adding fresh fluid. A power steering flush will definitely help prolong the life of the power steering components. Failure to have periodic power steering flushes results in important parts like the power steering pump, the seals, power steering rack, and the O-rings wearing out. To have a comprehensive power steering flush, call 603-436-9886 or visit Dow's Automotive Service today.

Heating and Cooling

Air Conditioning Service/Repair
If your car's air conditioning system is not keeping you cool don't let the hot weather make you miserable. Get back to cruising in comfort. Bring your car or truck by Dow's Automotive Service in Portsmouth and we'll get your AC working again. Call now at 603-436-9886 or stop by the shop at 909 Islington St, Portsmouth, NH, 03801
Radiator Service/Repair
Radiator Flush
A car's coolant system transfers excess heat from one part of the engine and finally loses it through the radiator fins. With time, the coolant becomes old and dirty. The old coolant will negatively impact the system's performance. To make sure the system is working effectively, consider having a regular coolant system flush. A coolant flush is basic maintenance for your car's cooling system. Call 603-436-9886 or visit Dow's Automotive Service in Portsmouth, NH 03801 for all your coolant system flush and fill needs.
Air Filter Replacement
Air Conditioning Recharge
Freon gas becomes a liquid when pressurized inside your car's A/C system but returns to its gaseous state as it leaks out. Many drivers in Portsmouth are completely unaware that they are losing freon until the day when they turn on the car's AC and find only warm air blows out. Call 603-436-9886 and ask any of our auto repair specialists about recharging your car's AC. Stop by our store at 909 Islington St and we will show you the best AC recharging options for your car.

Tire Rotation
Wheel Alignment
Check the tires - Check tire inflation and inspect the tread for uneven wear, indicating the need for wheel alignment. Also look for bulges and bald spots.
Tire Service
Tire balancing is an important area of preventative maintenance where we excel. If your car's tires are out of balance, they could be putting undue strain on components in the suspension, braking, and drivetrain systems, which can cost you greatly further down the road. Ensuring a smooth ride with professionally balanced wheels and tires is a much cheaper, easier, and safer way to make sure your car stays on the road, while ensuring a long life for your tires.
Tire Balancing

Brake Service
Brake Fluid Service
Brake fluid will absorb water from the air over time, causing the brake system to become less effective and the fluid to become corrosive, possibly damaging the system. It is important to perform a brake fluid flush regularly to ensure that your vehicle is using fresh fluid. Talk to our technicians at Dow's Automotive Service about when it's time for a brake fluid flush.
