Burp Cooling System with Airlift?

[Scootsmcgreggor]

Hey All,

I suspect I may have an air pocket in my coolant system. I'd like to put an airlift/vacuum on the system to pull out any air. I see all the instructions and references I can find say to start with an empty system. Can I just pull vacuum on a full system and expect that it will pull out any trapped air? Sorry for the newb question only ever filled and burped a coolant system the old fashioned way. Thanks in advance.

Have u tried the procedure like when u isntall a new radiator to let it gargle open? Also have u tried to "squeeze" some of the tubes?

Yes. But with fluidyne triple pass, boxed radiator and 948 oil cooler still got to 230CHT at buttonwillow with ~88* ambient temp. 9/10 pace. I would have expected it to be 15-20* lower so want to make sure there's no trapped air in the system.

Yes

Awesome thanks.

I have this and it works great. I'm sure you can find a cheaper option.

That is nicer, but pricey. Similar tool from OEM Tools or K-Tool are closer to $100 and work fine.
