I am going to flush my system then replace the LIM. With how much water is left in the engine after the LIM, how do I determine how much coolant to add?

Thanks.

All depends on where you live. You need to mix your coolant so it will not freeze at the lowest temperature in your area. You should buy something like this:

Amazon.com: Prestone AF1420 Professional Antifreeze / Coolant Tester: Automotive

and test the coolant when you mix it before you put it in your engine. I mix mine to around -30 to -40°F. That is safe for my area. If I lived farther north, I would probably have to adjust that a little. I think most will tell you not to go over 70%coolant/30% water.
