Review on ACDelco GM Original Equipment 10-108 Cooling System Sealing 🔧 Tabs - 4g (Pack of 5): Optimal Cooling System Maintenance Solution by Jared Barit

I purchased this product because my 2004 Cadillac DeVille had three coolant leaks; Radiator, coolant overflow pipe and cylinder head gasket. Fixing all of these leaks would be extremely expensive, especially replacing the head gasket. The workshop told me about these coolant sealing tablets, so I thought it wouldn't hurt to try. The store changed the coolant and added four of these tablets to the cooling system. That was a week ago and the coolant level in the expansion tank hadn't dropped at all so it looks like the pills were working. If you have a leak in your car's cooling system I would definitely recommend these pills. One note: if you have an expansion tank that takes coolant and no cap on the radiator, you will need to remove some of the coolant, disconnect the radiator hose, insert tablets into the hose, reconnect it, and then refill. coolant. If you just put the tablets in the reservoir, they don't get into the cooling system to do their job.
