Cooling System
I have read things about Dexcool anitfreeze that is swaying me away from adding this to my new rebuilt motor. Thoughts on this?

Adding distilled water to the block then fill up the radiator with either full strength or 50/50 mix coolant? Still unclear here.

Turning over the motor

I'm reading that priming the motor is the way to go before the initial attempt to starting it up. Can I just not have the dist cap off while turning the key? This should activate the oil pump, correct? Any other ideas?

2500 RPM's for 10 minutes is what I am told by my motor rebuild shop. Then 2000 and so on, does this sound right?

What else am I missing? Just want to be sure I am doing this right.

 

2 Gal Of concentrate (green) coolant and the rest water...... Perform Coolant flush every 35,000 mile or 3 years...
IF your not going to prime it with a primer tool...
Just light it off at idle, Quickly check for oil pressure and leaks...
Then 2500 rpm for 10 min.... Then fluctuate between 2500 & 2000 rpms ever so often for the rest of the 20 min break in....

 

It helps to put oil in the filter before you install it too.. Dexcool is a GM thing...
