My Chrysler over heats within 15 min I turn it on the water in the resevor bubbl

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Honestly if you are seeing bubbles in the coolant reservoir, it's a sign of exhaust back pressure coming from the engine through the cooling system. This usually indicates a breach of the cylinder head as it mounts to the engine - like a cracked head or cylinder head gasket failure. Have the engine checked for leaks internally.
