Sealant Tabs Continued


Recommended Posts

Dealer changed coolant, but wouldn't add the sealant tabs. Bought a pack last night and plan to add 3 to the system, but had a question. They are bigger than I thougt - do I need to break them up first? They came 6 to a pack.

Thanks for any info.

They turn to mush when exposed to the coolant. As long as they fit in the radiator hose, you should be fine.
