reverse water pump

...I think the blades suck the water from each side and push it out the middle out the outlet to the radiator.

Opposite of that.
Standard or reverse, the coolant always flows in the same direction through the radiator. Heated coolant flows out the top of the engine, into the radiator, and back into the engine from the bottom of the radiator after cooling.
The large port on the side of the pump is then always (on our engines anyway) the "inlet" side.
The two smaller internal ports on each side of the pump are the "outlets" through which coolant is pushed by the pump back into the block.

As far as I know, all engines run heated water into the top of a radiator and cooled water out of the bottom.

everyone is right in a way

here is what I see....
the pump casing that coscag00 has is set for standard rotation - the blades are however "reverse" from that of a "normal" water pump.
Timing covers do differ in the driver/pass ports and their angled direction between V belt direction or serp.
No mater what timing cover/ water pump combo one runs, water will flow through all components. How efficant the flow is, that is the question.

I do think though that if one had a tig welder that a piece could be welded across the channels that lead to the driver/pass ports. angled so that if you pointed a single blade at one of the channels then started from the center of the fan and carried a straight line off the back of said blade, that would be the line of the "damn" to be welded.
may work???

Well all points taken guys. Y'all have me questioning the pump now. You have no idea the hassle this pump has been as this is the 3rd one I have bought. I am going to run with it and see if it works. I will post up and let everyone know it will be awhile though.

All I can really tell you is that Tuff Stuff technical directed me to this pump for my application. If it dosent work I will get the BC Broncos pump.

if you need a reference, look at a 1993 mustang 5.0 pump. it is reverse (counnter clockwise) rotation.

Yes, ther is a huge misconception that the reverse rottion pump flows the water backward through the entire cooling system, that is not the case. Centrigual pumps are worthless trying to pull water.

As far as I can find there is no passenger side inlet reverse roation pump ANYWHERE that is correct. No MFG makes the casting. I looked at the BC reverse pump and it is cast for cockwise rotation as well.

~2 years ago I bought a pump from BC they sold as: HEAVY DUTY BI-DIRECTIONAL WATER PUMP. Never had any kind of issues with it. As a matter of fact I love it. I've never had any heat issues running it with my stock 3 core radiator.
