I found a front-only Aisin water pump. Presumably, it was for my son's '93 or '95 SC400. Any way to identify it more than it being an Aisin 5-B? I couldn't find this part by that number. Is it worth selling?

 

11 bolt SC300 (not SC400) water pump. Looks used. Most people do not rebuild these and they are thrown away/replaced. I would value this at $1

 

I agree with Joe, I would never install a used water pump with any age on it. Seals dry out. When I was young I saw several friends that were scraping for money install used water pumps on their beaters and they all leaked. Better to put it in the scrap bin.

 

Thanks! It will be gone. Honestly, I keep finding little parts.
