Q: car overheating
I have replaced the thermostat, water pump, radiator and radiator hoses also the knock sensors with the intake and manifold gaskets it was still overheating so I looked up online and saw that problem was most likely the head gasket. So I purchased bars head gasket sealant that seals anything from head gasket to cracked blocks, heads and followed the instructions. Before using sealant I flushed out the coolant system using peak super flush. After using the sealant I drove the car for test drive and after about less than a mile of driving, the car is still overheating.
