As you are driving down the highway you notice the temperature gauge suddenly spike, with smoke and steam spewing from underneath your hood. You pull over and check the engine, only to see your D16Y8 head leaking coolant. The cylinder head is top portion of an engine, and it houses the intake and exhaust valves that open and close when the crankshaft spins. A D16Y8 head gasket is a special piece of material that runs in between the two portions of the engine. This gasket seals the D16Y8 coolant passages. When a head gasket fails, pressure from the coolant system is lost, which results in overheating. This causes the cast aluminum head to warp or from cracks. A warped engine head has a chance to be repaired through machine work, but in most cases requires replacement. Luckily, there is a large selection of D16Y8 cylinder heads available in the vast inventory on eBay. A properly resurfaced cylinder head and a new gasket ensure the engine maintains proper operating temperatures. So, repair your D16Y8 head and get yourself back on the road.
