how long does it take to flush heater core ? And how much anter freeze do I new to fill back up? And do I just unplugs heater core tubes from water pump and back at heater core ? thanks
How difficult is it to get to those hoses on the heater core?one more thing, i always did it right at the heater fittings at the firewall, but shbox.com reccommends unplugging at the waterpump, so you can flush the hoses out too.
there's a restrictor thingie in those lines, so i found it was a faster job just doing it directly, and unlike the front of the engine where the entire ignition system lives, there's nothing back at the firewall to hurt if you spray water everywhere.
totally up to you
