FAQs—GMC Envoy XUV
How often should air-con service be done? The A/C of my GMC Envoy XUV is already malfunctioning. I want to prevent any serious A/C damage by being up to date with the maintenance.
The air-conditioning system of your vehicle should be serviced every 18 months to 2 years. Regular air-con service would prevent expensive A/C repair. Through regular checkups and cleanups, the system can run better much longer. The system won't be running too low on refrigerant. The system should be re-gassed as needed to make sure that the compressor won't be placed under a lot of stress as it's forced to work double time. This will prevent accelerated wear and will allow you to spot any potential A/C problem early on before the system requires more costly repairs or part replacements due to poor system maintenance.
If I add some performance exhaust on my GMC, how much hp gain can I usually expect from this upgrade? Will it really boost engine power?
Power gains from performance exhaust can range from 5% to as much as 20%. The performance gain would depend on the engine specs, the model, and other modifications. The design and type of performance exhaust also matter. Although performance mufflers and exhausts list increased hp as among their prime benefits, these modifications don't generate more engine power by themselves. Because of their less restrictive design compared to the stock, they instead allow the engine to reach its maximum power potential. As the engine breathes more easily, it can easily create more power without a lot of stress. Adding some performance headers could help boost the horsepower created by the engine—the extra boost could be anywhere between 10 to 20 hp. When outfitting the vehicle with an upgraded exhaust, look for a mod that best fits the engine specs. Also think about the expected power gains as well as the vehicle requirements. Consider the design of the performance exhaust to see if it's a good match for the vehicle and if it meets your expectations.
How can I tell if my GMC is already out of alignment? What would be the indicator/s? How often should the alignment of my vehicle be checked?
A vehicle could already need an alignment if you notice steering wheel shimmy or vibration and you have to firmly hold the steering wheel in able to drive straight. The steering wheel could be off the center. A vehicle that's out of alignment tends to pull to one side even if you're driving in a straight line. It may feel loose or it may tend to wander a lot. See if the tire tread has uneven or excessive wear. This is another common symptom of misalignment. Consult the vehicle manual for the recommended maintenance or service schedule. But generally, the alignment of the vehicle should be checked every 10,000 mile or once a year. It should also be inspected and adjusted when tires are changed or the suspension and/or steering parts are replaced or modified.
