spring is slowly making its way here and i need to start buying stuff for the car. my first task is to flush the radiator. now I'm going to buy a new thermostat with the gasket and flush the entire system. i read in order to get the heater core tubes flushed you need to set the climate control unit to hot, but no fan speed. is this right? also I'm gonna go ahead and use the recommended 50/50 dex cool cause its whats recommended and i don't wanna take any chances. how many gallons will i need to completely flush the entire cooling system? need to start buying the supplies so i can jump right in. since my intake manifold is leaking coolant, I'm gonna get an oil change right after to ensure clean oil is in the car. but all of this will happen before i flush everything out
