Performing regularly scheduled maintenance, like checking your hoses and clamps for wear and leaks, will help your Nissan Altima perform better and save you money on repair bills. Mechanics recommend you check your hoses and clamps every 3 months.
Look for Wear or Leaks on Hoses and Clamps
Move the Nissan Altima to a well-lit area where you can easily see and reach the engine compartment. Find the upper and lower radiator hoses, which go from the radiator to the engine and from the radiator to your exhaust manifold. The coolant hose runs from your radiator to your intake manifold. The heater hoses run from the radiator to the back of the engine block, as do the hoses attached to the intake manifold.
Use your hands to run the full length of each hose. Pay attention to how the hose feels: it should be firm, not soft or pliable. If you feel softness or you can easily pinch the hose with little give, it needs to be replaced.
