What's the best procedure to replace the antifreeze in the x350 4.2 VDP?
I drained the anti freeze from the radiator using the spigot on the bottom but I only got out about 1 and a half to 2 gallons. How do you drain the coolant from the engine? is there a cylinder block drain plug? If so, where can a I find it?
Any help would be greatly appreciated.

 

I usually disconnect the bottom radiator hose not sure on these

I take the car to get repaired these days if its wrong I have some one to blame LOL

Make sure you use the dexcool coolant again it does not mix well with other coolants other coolants can be used without problems but getting every last drop of the dexcool out makes that a bugger so I just went with dexcool again this is what my Indie recommended https://www.acdelco.com/parts/vehicl...ol-antifreeze/

 

Give these options a try

 

Sean, thanks for the helpful information. Essentially this is what I did but was concerned that I didn't get all of the old coolant out from the engine. So, actually, I performed this method twice thinking that the old fluid that remained in the engine was combined with the new coolant and then drained and refilled with a clean 50-50 mixture of DexCool gave me a better feeling about the whole thing. Thanks for the enclosed doc.
