how are yall flushing these trucks and leaving the block plugs in?

[Motorboy8769]

i have herd of people doing this and i would like to go this route should i just take off the bottom radiator hose and let the truck run and keep pushing distilled water through the truck until it comes out clean? and then refill?

I pulled the plug on the drivers side of the block and separated the lower rad hoses to drain. Then refilled, brought up to operating temp, let cool and drained again. Did this a few times over the course of a couple days.

I drained the system with the petcok and filled it back up.Then let it run and get up to opperating temp, and then opened the petcok again, and left a water hose in the degas bottle just to keep it full. I let it run for about 30 minutes with the petcok open and the water hose keeping the degas bottle full. That flushed the system really well then you can fill and drain with distilled water and then top off with your preferred brand of EC-1 coolant.

Just knock the drain plugs out of the block, it saves a LOT of time.

I took out the drivers side block plug but not the passenger side. I didnt want to remove the starter.

I removed both block plugs. The starter was actually very easy to unbolt and move out of the way. Its very small and light to. Just have to find the right combination of socket, extension and rachet. I think I used a 3/8" racket with a 4" extension and a shallow 6 point 1/2" socket on the top bolt.
