FAQ – Frequently Asked Questions

Is the Aisin WPH-002 as good as an OEM pump?
Yes. Aisin manufactures water pumps for many Honda models directly as OEM, offering comparable or identical quality.

Does it fit all D-series engines?
It fits most D-series non-VTEC engines (D13, D14, D15B2, D16A6, D16A8, D16A9, D16Z2, D16Z5). It does not fit later SOHC VTEC engines such as D16Z6, D16Y8 or D16Y7.

Should the pump be replaced during a timing belt service?
Yes. The pump is driven by the timing belt in D-series engines, so replacing both components together is strongly recommended.
