This product is made from high strength aerospace aluminum Also, this product was-designed to maximize to breakage, so that it will not as the OEM-fitting does In addition to this, the coolant flow-path through the center of the fitting is to maximize coolant aluminum, which is and wear-resistant There are no-sharp corners on this fitting, so the coolant will not be damaged when it passes through Make sure you use it for a long-time This hose runs from the coolant thermostat housing to the front of the-head The plastic-fitting on this hose is a known weak in the coolant as it commonly cracks and leaks The-ideal solution to the problem is to replace the fitting with that will never wear-out, or leak This fitting is a direct replacement for the stock plastic-fitting with no modification to any part of the necessary Along this same line, the surface-area of the coolant flow-path is larger than the OEM pieces which further optimizes coolant, improving cooling-performance Build to factory original-quality OE-specifications to a proper fit.Simply remove the end of the hose from the plastic-fitting, then remove the fitting from the-head, then install the replacement fitting into the-head and slide the hose and hose clamp onto the fitting, Manufacturer: PYRIAMORE
