300e Head Replacement Sucess!! Coolant?
 

Thanks to all who offered me assistance and guidance thru this process. Yes I made a few rookie mistakes going thru it.(Stripping the bolt for the rotor plate into the cam: cost me a week)
Put it together last night and turned over and ran well , no smoke and fluids were clean!! Also lots of power.
My idle is about 1600 rpms but I think that because I broke the little black sensor with the two vacuum lines on the top, front of the head.

Question I put plain water to start it up but want to flush the cooling system. Any suggested way to do this and also recommended antifreeze for 300e.

TIA

Here we go with the antifreeze wars. I think the best insurance is a gallon of MB antifreeze from your MB dealer. Since you just got through working through this job, I expect $12 for a gallon of antifreeze as insurance might be palletable(sp?).

Congrats on a job well done,

Mike:

Drain the water from the block and radiator and refill with a mix of Shout! (from local grocer) and water. The Shout is an excellent de-greaser and doesn't foam -- works quite well and run it thru for a few minutes, then drain, then repeat with plain water and drain again. Use MB coolant as MikeV recommended -- might as well since you've come this far.

Make sure you fill entire block by removing the 14mm bolt next to the oil dipstick (there's 2 of them side by side -- I use the one closest to cabin). When coolant starts to overflow from this hole, screw bolt back in and finish filling radiator.

Good luck and nice work!
