Q: How to inspect and replace radiator hoses and heater hoses?
A: During an inspection, check the radiator and heater hoses for deterioration, leaks, or loose clamps every 15,000 miles or seasonally. This can prevent potential breakdowns. Inspect the hoses when the engine is cold, looking for cracking, rotting, or collapsed hoses. If you find a weak or swollen spot, replace the hose. To replace a hose, first remove the radiator pressure cap when the engine is cool. Drain the cooling system into a clean container. Loosen the hose clamps and remove the hose carefully. Clean the hose connections and check the clamps, replacing if needed. To install the new hose, dip the ends in coolant, slide the clamps over the hose, and secure the hose ends over the connections. Refill the cooling system with coolant or a coolant-water mixture. Finally, check for leaks using a pressure tester or by running the engine until it reaches normal temperature.
