The equation you wrote is a special case of the ideal gas law. Not its simplified version. Ideal gas law does NOT have a simplified version.

Also, you forgot that the "air" you refer to will not be air, but mostly steam. The fraction of steam in the air will also change with temperature. You need steam tables not the ideal gas law.
And it's not steam, but air. Steam won't be produced until you boil your coolant. Do you use steam in your expansion tank to fill it up 100% or just close the cap?
Please refrain from posting stuff that goes over your head
