replace the upper and lower radiator hoses while your doing the radiator swap.... fyi. around 110,000 my coolant bleeder valve broke where the hose attaches at the fire wall ...(it allows coolant into heater core) .. the plastic had worn out over time and it simply failed.. i replaced that valve and the one to the right that has the long metal tube running behind the engine at firewall. once you install the new radiator, the best way to bleed any air is to start the engine with climate on heater and with reservor cap off... squeeze bottom radiator hose many times .. then top hose.. keep an eye on coolant level... it will rise after a little.. once you feel thermostat open.. squeeze hoses again... i like using a helper to watch the bubbles in reservor..
almost forgot... replace oem reservor cap.... and make sure your new radiator has the flat cap.. not the one with springs... if you install a fancy looking cap with a spring, it will eventually cause the coolant to blow a hose from too much psi
