Keeping on Track with Steering Position Sensors
Cars just keep getting smarter all the time. Sensors are being used to monitor more and more functions, and to share information between vehicle systems that formerly were mute or didn’t communicate with one another. One such sensor is the steering position sensor. The sensor’s basic function is to monitor the driver’s steering inputs. This
Tech Tip: Regular Belt Inspections are Important to Thwart Breakdowns
Serpentine belts are much longer-lived than V-belts, but they don’t last forever. After 50,000 or 60,000 miles, they often become glazed, noisy or cracked. A belt failure is bad news because all of the engine’s accessories that are driven by the belt stop turning. The vehicle looses cooling, power steering and charging output, and the engine quickly ….
Tech Tip: Pontiac GTO Font End Noise
Some 2004-2006 Pontiac GTO customers may comment on a knock noise from the front suspension when driving at low speeds over bumps or uneven road surfaces. This condition may be caused by the lower coil of the spring touching on the side lip of the spring seat. The illustration shows the rub mark on the spring coil. The spring coils contacting the body sheet metal within the wheelhouse area may also cause this condition ….
Brake Caliper Diagnostics
The owner of a 2004 Malibu says that there is a squeaking noise coming from the right front wheel. A quick inspection shows that the master cylinder is low on fluid and the pads are down to the sensor. You tell the owner that she needs to have the brake pads replaced. She responds that
So There is No Con-Fusion
came on the scene in 2006. The 2006 Ford Fusion shares a design platform with the Mercury Milan and the Lincoln Zephyr. In 2007, the Zephyr is replaced by the Lincoln MKZ. The Fusion comes with a choice of 4-cyl. and 6-cyl. powerplants. The four cylinder is a 2.3L 16-valve DOHC engine. It uses a
Tech Tip: Understanding Why Alternators and Starters Fail
One reason why alternators have a high failure rate is because they’re always working under a load. Generating electricity to recharge the battery, run the fuel pump, injectors and ignition system, and power all of the vehicle’s lights and other electrical accessories places a substantial load on the alternator that generates a lot of internal heat.
Swaybar Tune Up
A long time ago in a service bay far away, the average tread life of a bias ply tire was 20,000 miles. Even with belted bias ply tires, you did well to get 30,000 miles. Shocks, ball joints and bushings averaged out at 40,000. Today, modern radials can get 60,000 and suspension parts can go
Monotube Shocks
From the outside, most shock absorbers and struts look pretty much alike: a round steel tube that telescopes up and down with bushings or fittings on both ends. But inside there can be significant design differences that affect not only the ride control characteristics and performance of the damper, but also its cost. Last month,
Alternators & Starters: How and Why These Hard-Working Components Fail
One reason why alternators have a high failure rate is because they’re always working under a load. Generating electricity to recharge the battery, run the fuel pump, injectors and ignition system, and power all of the vehicle’s lights and other electrical accessories places a substantial load on the alternator that generates a lot of internal
Tech Tip: Inspect the Spring-Loaded Automatic Belt Tensioner when Replacing Serpentine Belt
Most late-model engines have serpentine belt drives for the engine-driven accessories. And most people know that belts are a maintenance item and eventually have to be replaced. But many don’t know the spring-loaded automatic tensioner that keeps a serpentine belt tight is also a wear item. Consequently, the automatic tensioner may also have to be replaced when the time comes to change the belt.
