Adding sealant to coolant

[John Kinnane]

G,day Eric I have one question for you, when you are flushing out the cooling system can you add a rad and gasket sealant to the coolant as a preventive for any small leak ect that might happen in the future? Also can you add any type of sealant, however I have read that you have to be careful if the coolant contains ethyl glycol to what you put in. Hope you can advise. Johnno. Could you do a complete engine flush on film.

Not recommending any sealants. If leaks are present
repair them correctly.

Thank you college man , I have seen other people add it to the coolant at the same time they add coolant, however if you don’t recommend it I wouldn’t do it. However could you do a video on flushing a vehicles cooling system or the method Eric uses because there are so many different ways on you Tub on how to do it. Johnno

These sealants can also cause issues such as clogged coolant passages and stop/break water pump impeller blades

Thanks Mate, I wasn’t thinking of using it but as I said I have heard people that have used it in the coolant after they have flushed out the system. Thank you once again RogueTeddy? Johnno
