One of the most important — and most overlooked — measurements in accessory drive setup is the water pump to balancer face dimension. If you're building a March Performance pulley system and your water pump or damper isn't stock, this measurement can be the difference between a system that aligns perfectly and one that throws belts. What Is the Water Pump to Balancer Face Measurement? This measurement is the distance from the front face of the harmonic balancer (damper) to the front …

How to Bleed a Power Steering Pump Introduction Bleeding a power steering pump is an essential maintenance procedure that removes trapped air from the hydraulic system. Air pockets can cause whining or groaning noises, erratic steering feel, and accelerated wear on critical pump components. Whether you have just installed a new pump, replaced hoses, or noticed symptoms of air in the system, a proper bleeding procedure will restore smooth, reliable steering performance. Why Bleeding Is Necessar …

The power steering pump pulley is one of the most overlooked components in an accessory drive system — but it plays a critical role in both performance and reliability.

If you're building an LS-swapped vehicle or upgrading an LS-powered car with a March Performance serpentine system, one question that comes up regularly is: does my engine have Variable Valve Timing (VVT)? The answer matters — and this guide will help you figure it out fast. What Is Variable Valve Timing? Variable Valve Timing, or VVT, is a technology that allows the engine's camshaft timing to change while the engine is running. Rather than fixed cam timing, VVT systems use oil pressure c …

Installing a serpentine system on a Chevy LS engine is one of the most popular upgrades in the swap and restomod world — and for good reason. March Performance's LS serpentine systems are precision CNC machined from 6061-T6 aircraft-grade aluminum and designed to give your LS swap a clean, show-quality look. But one of the most common fitment questions we get involves intake manifold clearance. Here's what you need to know before you start the install. Why Intake Manifold Clearance Is a Co …
