***6 Blade Water Pump vs 8 Blade??***

I think I have a 6 blade and looking right now to find out what 8 blade I should buy.

Mine starts to heat up in traffic. Have a BeCool aluminum radiator and probably a 180 deg thermostat.

I'm OK with the temp it runs except don't like it to keep climbing as it sits, you never know when you might get stopped in traffic for a long time.

I do have AC but it is aftermarket and have electric fan without a shroud.

Going to check out edelbrock 8 blade

Is your Lower Radiator hose collapsing? Sounds like its possible. Put a Spring in it or go get a good hose that is thick walled.

Or like crackedback says "put a soup can in it with a coat hanger wrapped around it" surely it will not collapse like that!
