500E/M119 Coolant Flush

[Michael]

Can anyone detail for me the most comprehensive way to get this done? The MBZ antifreeze is ready to go...I just need to know the best way to approach this.

Thanks in advance!!

The only way I know of to get out all of the coolant is to drain the block with the drains located under the heads.

You will have to drain the radiator separately.

Then refill.

I have a new tool that puts a vacuum on the cooling sytem then pulls in the coolant. Man it is cool, no more air pockets. The 119 was bad about this. No more.

Donnie,

Where'd you get the tool? Snap-on truck? I'd like one myself, especially for those pesky 4.5s.
