Anyone have a good procedure to drain ALL the coolant out of the beast?

I'm getting ready to make the conversion to Evans Cool and want to do this right

Thanks all.

 

Well I dont know if it got it all but.............
I hooked up a gismo I made up to the flush tee and my shop compressd air.
15psi blew a lot more out

 

It aint easy but try removing the block heater. If you do, make sure it's clean before reinstalling and use a new "O" ring.

 

Take the thermostat housing off (you are replacing it, aren't you ) and run a garden hose through it for a little bit. Works fine. That's how I flushed all of mine out. That and having the lower radiator hose fall off doing 70mph. It's amazing how fast the water pump can pump the block dry.

 

If you are going to flush your system with a hose, I would blow it out with compressed air as ratsun said. Otherwise the water left in the block could screw up the 50/50 mix that you and I need in these cold temps.

 

Thanks folks,

Right on Blue, I hear ya. Same happened to my 6.5 chev. (gee it aint raining but everyone behind me has their wipers on...) What are you running for a t-stat these days??

ratsun, the flush tee. Is this something you came up with or is it already there? (hope that's not a dumb question)

I understand that ALL of the water/glycol has to be removed before you add the Evans. Within reason that is. I guess a small amount (3-4%) can stay as long as it has an opportunity to evaporate.

Things like the heater core and such trouble me. Do I need to "stand her on end and shake" to get it all out??

Would'nt mine hearing from some of "the converted". Is this a straight dump in or does the t-stat need to be "high flow"?? other changes etc?? The Evans website suggests other things need to be done on most vehicles but no specific info for Ram/Cummins.

Any/all help apreciated.

Thanks guys

 

Just get the termostat from your dodge dealership. Your gonna pay a pretty penny for it (~$40) but it's worth it. The one I got from o'reillys was $30 and would allow the temp to get to almost 220 before it would open. The new one from cummins holds it steady at 185-190. When you go to flush it, turn the heater on to get the stuff out of there.

The flush tee is just a cheap plastic Prestone tee
I take the heater hose off the pipe clamped to the manifold and install the tee then back to the pipe with another piece of hose, attach the garden hose and pull the rad cap and presto reverse flush After I'm done I remove the flush tee just incase Col Murphy and crew show up
