Engine Pulley setup for your water pump

[Swhitney]

I assume my water pump is a factory flow, so it should be a reverse flow, correct? I want this to be as clean as possible, but the pulley doesn't have much grip on the water pump pulley.

If you want it to wrap around the other way, you’ll need to switch to a standard flow water pump

Go electric.

Go electric.

Well of course... Which one that will handle up to 700 hp?

Meziere.

I ran mine exactly like that for years. Still have the March setup just in case I ever need it again. Zero issues. There was a thread about this a while back. Several folks ran the same. Let it roll.

Thank you! I will let her roll.

I think we have a concept and terminology problem. The rotation of the pump is switched, not the flow, right? Going to a serpentine belt reverses the rotation, and so the impeller is different to get the flow to still go in the same direction. That is my understanding on 302’s or SB Chevies.
Some later engines actually cool backwards, but not the 5.0.

You are correct factory is reverse rotation.. The way you have the serp belt routed now will work fine as long as your running an electric fan. I've ran that setup on multiple mustangs for years including a daily driven one. Like mentioned above, if you want the belt to wrap around the pulley for more contact then you'll need to replace your pump with a standared rotation pump

Or put an idler pulley on the driver side of the engine

Out of curiosity, how much boost are you planning to run?

I'm not there yet. Still need to get a new block that will handle such HP. Right now I'm simply trying to future proof things. Currently running 450 hp to the crank.

reverse the tensioner and mount it on the driver side and you are good to go
