Vehicle Tips
According to recent studies, 5 percent of all motor vehicle fatalities are clearly caused by automobile maintenance neglect.
-
Vehicle Tips
The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of coolant should be checked. (A 50/50 mix of anti-freeze and water is usually recommended.)
-
Vehicle Tips
Never remove the radiator cap until the engine has thoroughly cooled. The tightness and condition of drive belts, clamps and hoses should be checked by a pro.
-
Vehicle Tips
Change your oil and oil filter as specified in your manual, or more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage or tow a trailer.
-
Vehicle Tips
Replace other filters (air, fuel, PCV, etc.) as recommended, or more often in dusty conditions. Get engine drivability problems (hard stops, rough idling, stalling, diminished power, etc.) corrected at a good shop.
-
Vehicle Tips
A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.
-
Vehicle Tips
Have your tires rotated about every 5,000 miles. Check tire pressures once a month; let the tires cool down first. Don't forget your spare and be sure your jack is in good condition.
-
Vehicle Tips
Check your owner's manual to find out what fuel octane rating your car's engine needs then buy it.
-
Vehicle Tips
Keep your tires inflated to the proper levels. Under-inflated tires make it harder for your car to move down the road, which means your engine uses more fuel to maintain speed.
-
Vehicle Tips
Lighten the load. Heavier vehicles use more fuel, so clean out unnecessary weight in the passenger compartment or trunk before you hit the road.
-
Vehicle Tips
Use the A/C sparingly. The air conditioner puts extra load on the engine forcing more fuel to be used.
-
Vehicle Tips
Keep your windows closed. Wide-open windows, especially at highway speeds, increase aerodynamic drag and the result is up to a 10% decrease in fuel economy.
-
Vehicle Tips
Avoid long idling. If you anticipate being stopped for more than one minute, shut off the car. Contrary to popular belief, restarting the car uses less fuel than letting it idle.
-
Vehicle Tips
Stay within posted speed limits. The faster you drive, the more fuel you use. For example, driving at 65 miles per hour (mph) rather than 55 mph, increases fuel consumption by 20 percent.
-
Vehicle Tips
Use cruise control. Using cruise control on highway trips can help you maintain a constant speed and, in most cases, reduce your fuel consumption.
-
Vehicle Tips
Keep your engine tuned. A fouled spark plug or plugged/restricted fuel injector can reduce fuel efficiency as much as 30 percent.
-
Vehicle Tips
Inspect the engine's belts regularly. Look for cracks or missing sections or segments. Worn belts will affect the engine performance.
-
Vehicle Tips
Have the fuel filter changed every 10,000 miles to prevent rust, dirt and other impurities from entering the fuel system.
-
Vehicle Tips
Change the transmission fluid and filter every 15,000 to 18,000 miles. This will protect the precision-crafted components of the transmission/transaxle.
-
Vehicle Tips
Inspect the suspension system regularly. This will extend the life of the vehicle's tires.

I would like to thank Bill and his mechanics for there outstanding performance diagnosing and fixing our expedition in such short notice. We were on our way from Connecticut to Maine when our SUV broke down, we were very lucky to be given CDS's address. When we got there we spoke to Bill he took our vehicle right into the shop and told us not to worry he would have us back on the road as soon as possible and that is what he did. The mechanic that worked on our vehicle skipped most of his lunch just to get our vehicle done and when it was time to pay the bill we were very pleased Bill was very fair with the price he changed and much cheaper than it would of been going to the dealership and having it fixed. I can't say enough nice things about CDS. Thank you Bill for being a kind, caring, and honest guy. We really appreciated it because of you and your mechanics we had a great vacation.

I go out of my way to get here for major repairs and maintenance after experiencing some deceitful practices at other shops. Repairs here are done right the first time with up-front disclosure on parts being used -- usually meaning more of the cost is going into quality parts rather than inferior parts with inflated labor.

Trustworthy service at a fair price. Honest treatment is exceptionally rare in the auto repair business. Chelmsford diagnostic services takes care of everything with care and detail. Always an accurate estimate before the work. Fast turn around. Bill is in a word, trusted. Inspections to tires, all the mechanical stuff.
