I used this 4-5 years ago in my 2008 chevy impala with a 3.5 ltr engine. 115,000 miles later I am still driving it down the road everyday. I noticed the coolant is starting to slush around a bit in the heater core, any thoughts on this product and what I can do to get rid of the excess air?

The problem with many sealers are that they will clog up a heater core and it may need replacing now but if you Jack the front of the vehicle three or four feet higher than the back then the air will come out of the radiator by opening it when it's cool starting the vehicle and let it warm up
