Pulley Water Pump HTD 36 Tooth

The Pulley Water Pump HTD 36 Tooth by Jones Racing Products is a precision-engineered serpentine pulley designed for serious engine builders and performance enthusiasts who demand synchronous belt drive reliability. This HTD (High Torque Drive) profile pulley is ideal for custom cooling and supercharger applications where eliminating belt slip is crucial. It ensures consistent coolant circulation under peak load conditions, making it a vital component for high-performance builds.

The 36-tooth HTD profile delivers positive power transfer by locking the serpentine belt into fixed teeth, effectively eliminating slippage that can occur with standard V-belt designs. This is especially critical when engine load increases or boost pressure rises, as slippage can lead to reduced coolant flow and potential overheating. The HTD geometry also helps distribute torque evenly across all engaged teeth, which reduces stress concentration and extends the life of the belt.

Builders working with supercharged, turbocharged, or carbureted big-displacement platforms will find this pulley's reliability and performance consistency particularly beneficial. Its compact design integrates seamlessly into HTD-based accessory drive systems and pairs well with matching crankshaft and alternator pulleys for complete synchronization. This makes it an excellent choice for those looking to enhance their engine's cooling efficiency and overall performance.
