Is your fan belt squealing, jumping off the track, or vibrating excessively at high RPMs? The culprit is often a bent or warped Water Pump Pulley. Over decades of service, pulleys get dented from being pried on during repairs, or they rust at the belt contact surface, chewing up expensive new V-belts.
At Old Car Parts NW, we stock authentic OEM and NORS water pump pulleys to restore proper belt alignment and cooling efficiency.
Prevent Thrown Belts: Even a slight wobble in the pulley can cause V-belts to fly off at highway speeds.
Correct Cooling Ratio: Using the wrong size pulley can spin your water pump too slow (overheating) or too fast (cavitation). We list our pulleys by diameter and groove count so you can match the factory drive ratio.
Steel Durability: Unlike cheap chrome dress-up pulleys that often lack grip, our inventory features proper stamped steel or cast iron units that hold the belt tight.
Single Groove: For simple, non-A/C applications.
Double & Triple Groove: For vehicles equipped with power steering and air conditioning.
Applications: Hard-to-find pulleys for Ford FE & Small Block, Chevy Small Block/Big Block, Mopar, and Pontiac engines.
