OEM vs. Topline Waterpump: Visual Differences *Pics*

[hopwoodp]

Mike, PM me the name of this supporting vendor for this again. I'd like to have it on file.

Ludacris,

I can also vouch for spoolin98 on this vendor.

Ludacris,

Considering my PM box filled up in two days, I'm sure many can. Thanks

Everyone should just do the right thing here.

Just as a note, when I received my Mitsu pump that I bought from the dealer it was in a plastic bag but also came in a brown box with the Mitsu part sticker on the outside.

Yeah thats the way it should come.

Please guys, take this into consideration and act upon it. Thanks Chris.

I know this isn't a water pump I'll be speaking of, but it's a Topline, and a pump. I ran on of their oil pumps and it cost me my six-bolt 3000 miles after the swap. OEM, OEM, OEM... I saved $70 on the pump, and it ended up costing me thousands after words.

It wasn't off topic, I said that I spent thousands at the same *mystery* vendor and was treated like crap as well.

That's not the topic, waterpump differences is the topic. Bashing vendors in any form and "Me too" / "PM Me" / posts to up your postcount in a technical forum are all against the rules.

Are we done here

The thread topic is "OEM vs. Topline Waterpumps". All vendor related posts will be deleted. Ludachris has made it clear as to what to do to "report" an issue with a vendor.

i have never used the top-line water pump personally. I have a few friends that run them and don't seem to have a problem. Sorry to see you got hosed bud.

Hey Defiant

About what you said in regards to plastic impellers - does it matter at all if it is a closed or open impeller that could cause internal failure? Also, do we know if Mitsubishi makes these kinds? And if not, who does?

I don't know who makes nor sells them. They seem to fail at the hub, and I don't know if one type is more liable to fail than the other. Both designs are meant to be strong enough, but the heat and strain seem to be too much for some of them.

Thanks for the info Defiant - So, who would make a good closed impeller water pump? I remember reading a post that talked about the differences between the two and they mentioned how the closed impeller was more efficient and doesn't have cavitation issues. Some pictures were also put up showing the different designs and one of the last post mentioned how the closed impeller looked plastic and how this one guy had a plastic open impeller water pump and it failed in the area like you said.

I'd still not go with plastic. There's more than enough meat on those metal impeller blades to not be bothered by cavitation erosion before the seal and/or bearing fails, and neither of those will be occurring before it's timing belt time again.
Hoary as it looks, the steel impeller will be just fine.

I guess this other(new) water pump is not going on my next build then. Thanks Defiant.
