Grand Am Tech Tips
The Pontiac Grand Am was originally offered as a mid-sized car and was later remodeled to a more compact style by its manufacturer, General Motors. Owners of Pontiac Grand Ams can typically extend the life and use of their vehicle by following a few simple tips. To help insure safety, however, automotive concerns should always be inspected by a certified mechanic.
Noise When Applying Brakes
Noise that becomes noticeable when the brakes are applied on a Pontiac Grand Am can be caused due to a number of reasons. A common reason for noise when the brakes are applied is dust in the brakes or worn down brake pads. If the brake pads are new and you have been able to rule out dust as the culprit, another common reason that could be causing the brakes to make noise is a problem between the caliper piston and the steel interface, which is typically noticed during slow speed braking. Brakes that make noise of any kind should be inspected by a certified mechanic in order to determine the problem and prevent additional damage to the brake system.
Coolant Warning Light
If the coolant level warning light appears on your dash, your first step should be to check your coolant to ensure that your levels are sufficient. If the light comes back on after checking to ensure that you have enough coolant, the problem may be with the chamber in the coolant reservoir. Often times, the culprit is sediment that has collected in the reservoir and settled down around the bottom of the float. This sediment causes the float to stick to the bottom, incorrectly signaling the engine that the reservoir is empty. Try removing the coolant reservoir and shaking it upside down. This should release the float from being stuck to the bottom. If after replacing the reservoir, the light remains, the problem may be a faulty fuse that needs replacement.
Speedometer Not Working
A broken speedometer can not only be frustrating, it can lead to a speeding ticket. When a speedometer has stopped working, its often due to a faulty fuse that is connected to the speedometer. When the fuse stops working, it stops sending power to the vehicles computer, making it impossible to determine what speed you are actually going. If the rest of the gauges are working, but the speedometer is not, try replacing the fuse. If after replacing the fuse, the speedometer still does not work, you may have an electrical short in your dash that will need to be inspected by a certified mechanic.
