OEM-Grade Engine Coolant Pump for Toyota Platforms ⚙️

Keep your Toyota’s temperature under control with this precision-built engine coolant pump, OE ref 16100-39545. Engineered to Toyota OEM standards, this water pump restores factory cooling performance, stable power, and long gasket life.

Why this part is needed ️

Without strong circulation, hotspots form in the block and heads. This unit keeps coolant moving through radiator, block, heads, and heater core, stopping overheating, protecting head gaskets, and preventing oil breakdown.

How it works

A belt drives the pulley, spinning a balanced impeller inside a rigid housing. The mechanical seal holds pressure and coolant, while a heavy-duty bearing keeps the shaft true. A precision gasket/O-ring closes the joint for leak-free operation and steady flow.

When it fails

• Coolant leak from weep hole or around the gasket
• Growling noise or pulley wobble
• Overheating, weak cabin heat, boiling in reservoir
• Warning light or limp mode from high temperature

Tech tips ️

Flush coolant, clean mating surfaces, fit a new gasket, torque bolts in a star pattern, set belt tension, and bleed air. Inspect thermostat and serpentine belt and replace if worn for best results.
