ismalley well proof will be in the eating .The next time , in a few weeks time that will be after i fit my new wing . Then it will be time to do this coolant change And i will use your method ..I will then let you know just how the coolant refill goes .

Should be easy. Remember Make sure the system is all back together and everything is buttoned up. No need to turn on the car. Just start filling from the coolant reservoir and when it starts to get full, stop and jumper the aux wp and let it circulate coolant throughout system. Keep aux wp running while you add more coolant. When you reach the satisfied level, you're done.
