Signs of a cooling problem

  • The temperature gauge climbing toward the red.1
  • Coolant that keeps going low, which means a leak.1
  • Hoses or belts with bulges, blisters, cracks or cuts.2
  • No heat in winter. Low coolant keeps heat from reaching the heater core and can also damage the engine.3

What gets checked

  • The system for leaks, the coolant itself, and old coolant replaced as needed.4
  • Belts and hoses, which break down as summer temperatures rise.2
  • The coolant change interval for your vehicle: older coolants every two years or 24,000 miles, most modern ones five years or 50,000 miles or longer. The owner's manual sets it.5

Why it matters

Cooling system failure is one of the main causes of breakdowns.6 Without maintenance, the odds of engine damage and a summer boil-over go up.5 An engine that runs too hot can warp cylinder heads, blow head gaskets and, in extreme cases, crack the block.7

Never open the radiator cap on a hot engine. The coolant is under pressure and boiling, and it can cause serious burns.5

Las Vegas summers

The system that works hardest here

Las Vegas averages about 78 days a year at 100°F or hotter.8 AAA says engines work extra hard in summer and the cooling system is what protects them from overheating.5 Stop-and-go traffic adds load, because the engine idles more than on the highway; in hot weather, watch the temperature gauge.1

Gasoline or diesel, car or work truck, bring it in before the first 100-degree week. If the A/C is struggling too, see A/C and heating.

Questions people ask

What should I do if my car overheats?

If the temperature needle reaches the red, pull over and turn the engine off immediately.1 Do not open the radiator cap while the engine is hot: the coolant is boiling and under pressure.5

Why does my coolant keep getting low?

The cooling system is closed, so coolant that keeps going low means there is a leak somewhere.1

How often should coolant be changed?

It depends on the coolant: older types every two years or 24,000 miles, most modern ones at least five years or 50,000 miles, many about 100,000 miles. Your owner's manual sets the interval.5
