Tis is the K18 engine same as K16. It is the twin camshaft petrol engine where the engine is a fully aluminium and very sensitive to temperature.surely the problem you have is the compression gasket. Now you must be very carefull on trying to fix it. You need a good machinery job to check very well the cylinder head and also the cylinder block because the piston liners are replaceable and depends to the overheating removed from the proper position fitted. If everything is correct and by skimming the cylinder head problem will get solved, must buy the new three leaf metal gasket kit and all new cylinder head bolts.

You either have blown circuits in the radio itself, or the wire bundle output to the speakers are broken/shorted out or the connector has come loose on the radio/speakers. The last usually doesn't happen however. If the speakers were blown...you would get something. Take your vehicle to a reputable house and have them check it out.
