Bests & Worsts Reviews from Amazon

I fixed a very small leak on a 5.4 triton, It was using coolant, It was not overheating. It took one and a half bottles according to the recommended amount according to the cooling system capacity. I took the thermostat out Flush it with the garden hose Refill with water leaving room for the 1.5 quarts Pour SLOWLY the sealer Let it Idle for an hour Turned the engine off and let it cooled down overnight next morning I put the thermostat back Refilled with coolant NO MORE ISSUES I would totally recommend, it's been about 5K miles and no problems.
