I'm still getting parts to finish off my timing chain replacement...

Is there more than one Water Pump (different impeller size) used in the 22R engine?

there's a...

GMB Japan w/pump 18R-22R 62mm impeller
&
GMB Japan w/pump 20R-21R-22R 69mm impeller

Does anyone know which is which, and why the cross-over of year models?

Thanks.

I believe either one will work, I'd prefer the one with the larger impeller.

Cant the dealership decipher this for you?
