Description
Holley GM LS Swap Mechanical Water Pump – Forward Facing Inlet
Engineered specifically for low-clearance engine swaps utilizing GM LS truck accessory drives with long belt alignments.
Product Overview
When swapping a budget-friendly GM LS truck engine into a low hood clearance vehicle, standard factory water pump outlets point upward and interfere with hood lines. The Holley 22-101 mechanical water pump solves this common LS swap clearance issue without requiring a costly conversion of your existing front accessory drive system.
Crafted from durable cast aluminum, this performance mechanical water pump features a forward-facing inlet neck that routes radiator hoses horizontally. It maintains full compatibility with long belt spacing (truck accessory drives) while providing OE-matched cooling performance for high-demand street and motorsport applications.
Key Features
- ☑ Forward-Facing Water Inlet: Redirects radiator hose routing horizontally to eliminate hood clearance issues on custom swap builds.
- ☑ Truck Accessory Alignment: Designed for long belt spacing, allowing retention of cost-effective GM truck accessories and brackets.
- ☑ Universal LS Engine Block Fitment: Fits all non-supercharged GM LS family engine blocks including 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, and 7.0L.
- ☑ OE-Matched High-Flow Design: Custom-tooled aluminum housing and durable steel impeller match original equipment cooling efficiency.
- ☑ VVT Cover Clearance: Contoured housing clears Variable Valve Timing (VVT) timing covers found on 2010 and later LS engines.
