Hose failure can cause an overheated engine. If a hose leaks coolant the cooling system is inoperable. If the engine overheats, it can suffer serious internal damage that requires expensive repairs and can ruin a summer vacation to San Diego.

Overheating can occur anytime, but usually happens in the summer. Under the hood temperatures are much higher, and heat can trigger or accelerate deterioration of rubber compounds.

There's nothing worse than sitting by the side of the road waiting for a tow truck in Phoenix's 110+ heat with a car that overheated, so here are some things to look for:  

Hoses are your cooling system's weakest link that wears out more commonly than all other parts. Made of flexible rubber compounds, they absorb vibrations between the engine & radiator, or the body's firewall. Hoses are attacked by not only atmospheric ozone, but also hot and cold weather extremes as well as dirt, oil and sludge.

The most common hose failure isn't easy to detect. It deteriorates from the inside, causing tiny cracks. Acids and contaminants in the coolant can then weaken the material that reinforces the hose. Eventually, pinholes can develop or the weakened hose may rupture from heat, pressure, or constant flexing. You can look for this by:

  • Checking the coolant-recovery tank (white) to ensure proper fluid level. If the tank is low after being refilled suspect a leak. Also check for white, light green, or pink coolant tracks on the engine – that is most likely residue left from dried coolant that leaked out.
  • When the engine is cool, squeeze the hoses with your thumb and forefinger near the clamps - feel for soft or mushy spots. A good hose will feel firm yet flexible.
  • Inspect for cracks, nicks, bulges or a collapsed section in the hose and oil contamination. Look for fraying near the connection points.
  • Look for parallel cracks around bends (caused by ozone), a hardened glassy surface (heat damage), or abrasive damage (hose is rubbing).

Hoses usually fail in this order:

  1. The upper radiator hose
  2. The water pump bypass hose
  3. The outlet heater hose from the engine to the heater core

Most car manufacturers recommend all hoses be replaced at least every four years or when one fails, which ever happens first.
