Well I am always working on something new. I wish I had seen this a week back as I just flushed my 300SD and shelled out $40 at Napa. Oh well.
When I change the coolant filter on the PSD I have to add coolant.
I had a heater core fail this summer in one of my E23 BMW 745i and had to add coolant. When it goes in for a valve job I will need some.
SDL is getting a new top end here too.
Makes sense to me to buy some.
