Thank you Chevyguy, i will check that out tomorrow or the next day and post my results here for you to see
. I actually think there was some gunk in the coolant system as when i first did the water pump it seemed like there was some slimy properties to the coolant,didnt see chunks but that very well could be the problem. Will flush it again too but with prestone like you suggested and blow out heater core too. Praying your onto something
. I also have been a chevy guy my whole life and this is my daughters 2nd bmw but my first one working on.
