Thanks for your feedback. While I am waiting to check in my car (scheduled for engine removal in mid-November due to repair work of the shop - a long story) I popped in GM Coolant Supplemental tablets (ground up walnut shells and ginger root - no s**t invented for Caddy alum. engines) and seems to have stopped steaming and no burping into the recovery bottle when radiator cap is removed. This tells me amount of blow back into the cooling system seems to have been reduced substantially. However, after 10-15 miles and cool down, coolant level drops to reveal lower pipe coming from the recovery bottle. Your comments tells me she is still blowing into cooling system.

Thanks.
