5 Serpentine System Installation Mistakes to Avoid

Belt squeal and pulley slip can quickly dampen the thrill of a new build. We’ve noticed common mistakes repeatedly. Here’s how to prevent them and keep your project on track.

Misaligned Pulleys: Just a few millimeters can lead to belt wear.
Incorrect Belt Tension: Being too tight or too loose causes noise and damage.
Wrong Pulley Ratios: Can starve accessories or cause overheating.
Skipping Proper Hardware: Using cheap bolts and spacers disrupts everything.
Contaminants: Liquids on the belt can lead to slipping, squealing, and early wear.

That's why March kits are trusted by builders everywhere for their reliable serpentine and V-belt systems, designed for a perfect fit and smooth performance, mile after mile.

Some engine bays deserve a closer look.
