This PN consists of a 25mm (1.0in) hose and a plastic fitting. 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. The ideal solution to the problem is to replace the fitting with one that will never wear-out, crack or leak. This fitting is a direct replacement for the stock plastic fitting with no modification to any part of the system necessary. Simply remove the end of the hose from the plastic fitting and then the fitting from the head (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. Fitting is machined from billet aluminum 6061 T6511 (not cast, not forged)..
