Function:Made of aluminum, it is durable, wear resistant, and has high breakage resistance.The coolant flow path through the center of the fitting is optimized to maximize coolant flow.There are no sharp corners on this fitting so that the coolant will not be disrupted as it passes through.This hose runs from the coolant thermostat housing to the front of the head.The plastic fitting on this hose is a known weak spot in the coolant system as it commonly cracks and leaks.Easy to install, just simply remove the end of the hose from the plastic fitting and then the fitting from the head (the hose does not need to be removed from the thermostat housing to do this); Then install the replacement aluminum fitting to the head and slide the hose and hose clamp over the fitting.
