Lennie,Hi. My tire inflator kit has never been used. The 700 ml sealant bottle indicates the contents are best before 2008. Is this sealant still available through GM? Is there a substitute? Thanks.
Some do, some don't, it depends on which pump you have.I too carry a mounted spare tire but I wanted to warn you that the air compressor unit has sealant pre-loaded into it and you need to make sure that it is disconnected at the bottom of the compressor that if you want to use it just to inflate your tire without using the sealant.
Very true "WM" when I worked at Bud's Tire ... the Shop guys hated and I mean hated to see a tire come in with Sealant in it. Had to get all the "slime" outa' there before it could be patched. I do carry a can of it in my Cargo area ... hope I don't ever have to use it. Gettin' a 17 X 7 rim with 6 on 5 lug pattern shortly I hope. tennesseecozydog & Red Molly :ssrI recommend you replace the sealant can and have one that isn't expired on hand if needed. While traveling I had a flat and had to use the sealant to get me to a shop. I let them plug the tire as a short term fix. After returning home I had a patch put on after they had taken the wheel and tire off. If I remember correctly it took them a couple of hours to do the work including cleaning all of the sealant out of the tire. They said if you leave the sealant inside the tire will be harder to balance.
