Look for Wear or Leaks on Hoses and Clamps
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.
Inspect each hose for cracks, frisions or tiny tears. If you find any, replace the damaged hose immediately. Wipe away grease before checking your hoses and clamps so you can easily inspect the parts.
