💡 How does an auxiliary coolant pump actually protect the engine block?
The secondary circulator adds fresh fluid flow exactly where the primary water pump loses mechanical advantage on older or high mileage drivetrains.
- Increases heat rejection rates by forcing antifreeze past restricted exhaust manifolds
- Lowers combustion chamber stress by keeping piston ring contact zones at optimal temps
- Extends overall cooling system life by reducing reliance on failing thermostats and fans
