I drove up to the Summit Racing shop in Nevada and I bought a set of underdrive pullys CHEAP. Crank pully and waterpump pully for 25 bucks. My question is if im going to drive the waterpump slower should I install one of those "flow cooler" impeller disks on it ? It is a standard volume pump right now.

Maybe. I don't like underdrive, but that's just me. You might consider an aluminum high flow pump if you have heating problems.

Would a more huge radiator do the trick ? The brand new f-100 radiator leaks so as long as im taking it out of the truck im gonna upgrade to the heavy duty version.... or is it strictly a water volume thing ?

You'll just have to see. You need enough volume to move the water around. It just depends on how much you're slowing down the pump. More system capacity is always good.

I think the purpose of the flow cooler disks are to prevent cavitation which happens when the impellers are being driven at high rpm. If you are slowing down the pump there shouldn't be a problem with caviation.

The disks are for heatsoak of the fluid also no?

WTF? Heat soak of the fluid? That's kinda the idea behind liquid cooled engines is to transfer the heat from the engine to the ambient air by way of the coolant/antifreeze conducting the heat to the radiator.


Simply put you want the water/coolant in the engine long enough to pick up a reasonable amount of heat(200*-220*) but not too long that it gets hot and starts to boil(240*+).

I have a tiny crank pulley and I do have cooling issues and charging issues, but only if I idle for a significant period of time, once I'm moving its no problem.

You should use a slightly larger crank pulley or a smaller Alt pulley and an electric fan.

Hotter the coolant exiting the engine is, the more heat energy is transferred in the radiator to the air - provided you have enough fluid moving through the engine to cool it. You're limited by things like metal melting and coolant boiling.

If the underdrive makes it run warm, consider picking up a high volume pump, and make sure you get a HV thermostat also - stock ones can be forced open by high volume pumps.

No, I had it right.

OH! Pardon the misunderstanding! Im sure you see my confusion.

No need for the "WTF" or red print though??????? Sheesh....

I dont understand the bashing for trying to helpout even if accidently misdirected. I did not see impeller for some reason.

That is a very interesting piece, I did not know they could be bought as a add-on.!

The red print was to merely make my comment readable as the black made it blend in with the links. No flame intended.

Wait, so that disc turns makes the impeller grab more coolant? Kind of like a paddle wheel ??
