Radiator suggestions

Idk what happened to reply but here goes again

You typed between the [quote.... And the .....quote]

So your wp pulley and your crank pulley are both 6.5" that means you are not over driving OR underdriving your water pump.

You might gain by replacing the wp pulley with one slightly smaller in dia (6"??? That would overdrive your wp by about 8%)

But I still think you have something else going on.

Hope your new radiator fixes your issue.
