The installation involves draining a portion of the cooling system, removing the old outlet hose, and fitting the new hose onto the existing OEM fittings using the factory hose clamps. Refill and bleed the cooling system after installation. While a confident DIYer can complete this repair, professional installation by a qualified technician is recommended to ensure proper torque on clamps and a complete cooling system bleed.
