coolant flush while engine is out and apart.

[ksobiech282]

I've got my 06 all torn apart as I am putting in ARP's. I am also replacing the engine oil cooler at this time as well. Can I safely flush everything while its torn apart? I've never done a flush before. I'm in the process of cleaning the surface on the block that the heads go onto. As careful as I am I know I'm still getting debris in the water jackets on the block. So I wanna flush all parts of the cooling system(from all the water jackets to the water pump and everything else) so any suggestions? I also wanna be careful not to plug up my new engine oil cooler. Thanks in advance

Ahhh Dude you are really supposed to flush before ya take the engine apart. Kinda hard to do now without fabricateing some blank off plates.

Ahhhh lol that makes more sense haha. But what about cleaning out the water jackets then

I wouldn't touch the block, but you can take the radiator out and get that cleaned, also back-flush the heater core. Remove the block plugs to get any remaining coolant out of there. When you put it back together, at least the radiator and heater cores will be clean. Then flush a lot and if you're concerned about the oil cooler, reverse flush that with every evacuation of the engine block.

Awesome thanks for the heads up. Any special way to reverse flush or can I just take it in?
