I know this seems kind of weird, but I'm about to replace my water pump, which is not stock and is all rusty on my 92 rs with the L03. I've seen pics of people's pumps painted black and bare rust and I want a mostly stock look. Is your factory pump bare metal or painted black. Also, what year is your car. Thanks for the help.

 

My pump is black form the factory and is a 1990. Every other stock pump I have seen was black as well.

 

rusty colored.


because alot of them wernt painted from the factory.

the ones that were, were fogged the same color black as the intake and block.

 

mines rusted, no paint, doesnt looks like there ever was paint. 92 rs 305

 

Mine has some realistic, cruddy, used oil type of paint on it. If I didn't know better, I'd think it was real oil!!

 

Mine was rusty when I bought my car, and the motor had been rebuilt the year before I got it. I assume that was a replacement pump. A year later that pump failed and I noticed when I bought a rebuild, it was already starting to rust around the edges, even though it was painted, so I fogged it black.
I think the paint on most replacement pumps is only intended to prevent rust until the part is sold (think headers).

 

lol, now I'm even more confused. Looks like the factory wasn't very consistant. Thanks for the help guys.

 

paint it. flat or gloss black will look fine and help protect from rust

 

Everyone that I've owned was painted.

 

was yours?

purely cosmetic.... just looks.

even if the pump sat in salt water for 100 years, it would not corrode thru. its thick cast iron.


99% of the replacement pumps ive seen, have been painted though...

i know most factory pumps were not painted... id say they never were, but im not confident in that fact..... and theres no way to prove it anyway..

id either leave it unpainted or fog it the same black as the rest of the engine.

 

mine was rusted when i got my car. i dont see the point of letting something rust though
