Engine flush
« on: September 20, 2017 - 05:30:30 PM »
I pulled the heater hoses off and both outlets were completely blocked. I plan on replacing the water pump. Can I flush the block without the radiator? I have a new radiator and don't want to risk plugging up the radiator. I'm sure the heater core is probablt toast.  Ii forgot to mention it's 1970 a slant six.  Thanks
