Overview
A genuine Aisin engine coolant water pump for the Honda B-series. Timing-belt driven, it circulates coolant through the block and radiator to hold stable temperatures across the whole rev range, even under sustained hard use.
For owners of B16A/B18C VTEC engines who want an OE-grade replacement over generic aftermarket. Aisin is a Toyota Group supplier and a factory OE source for Japanese cooling parts — the natural pump to fit during a timing belt service.
