Frequently Asked Questions

Why should a professional mechanic use ACDelco Gold parts?

ACDelco Gold (Professional) parts are designed to meet high standards for quality, durability, and performance. They often utilize the same manufacturing processes as GM Original Equipment parts, ensuring reliable fit and function, which minimizes installation time and reduces the risk of comebacks.

How often should brake fluid be tested for moisture?

Brake fluid should ideally be tested at every major service interval or at least once per year. High moisture content significantly lowers the fluid's boiling point, leading to brake fade and potential system corrosion. Tools like the 5-LED Brake Fluid Tester make this check quick and easy.

What is the benefit of using an OE-style oil filter like the ACDelco PF46E?

OE-style oil filters are engineered specifically for the vehicle's engine, guaranteeing the correct micron filtration level, flow rate, and burst strength. Using a filter that meets these exact specifications ensures optimal engine lubrication and protection, particularly important for maintaining vehicle warranties.
