Wapu - How To Identify A Wapu


Recommended Posts

Hi guys,

found this on the web, now how to identify the two wapus?

Hydraulic unit water pump Part Number 16090-49017

Hydraulic water pump pulley Part Number 16939-46010

This one turns the fan, right?

Non-Hydraulic water pump Part Number 16100-49846

Non-Hydraulic water pump pulley Part Number 16371-46020

This is the same like from the 2JZ engine, right?

My car looses water from the wapu, so i have to check this.

Do i have to remove the timing belt like on the Nissan Skyline R33 to change the wapu?

If so, any recommendations for Greddy/HKS/OEM Belt & timing gears?

I plan to fit a greddy fmic kit, any props to this?

Thank you Rocka
