If your vehicle is overheating, your engine is screaming for attention and your cooling system needs help. A vehicle can overheat at any point where the cooling system no longer is effectively absorbing, transporting and dissipating the heat created from your engine burning fuel.
Here are some of the most common reasons a vehicle’s cooling system begins to fail:
1. Leaks in the Cooling System
Leaks are the #1 reason a vehicle begins to overheat. Leaks in hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs and a few other things can all lead to problems with the vehicle’s cooling system. If you suspect a leak, or have had to add coolant to the reservoir don’t wait to get it checked. A small leak can quickly turn in to an expensive repair and a serious headache.
2. Coolant Concentration
You always want to use the correct type of coolant in your vehicle. The wrong coolant or the wrong mixture of coolant and distilled water can cause your vehicle to overheat. If you’re worried about your coolant concentration and haven’t kept up on regularly-scheduled vehicle maintenance, a complete cooling system flush is in order. Coolant actually becomes corrosive over time, accelerating the wear on the cooling system!
3. Bad Thermostat
Your thermostat is a key valve in the cooling system that ensures the coolant is able to pass through to the radiator when necessary. When the thermostat gets stuck in the closed position, coolant can no longer pass through and becomes overheated in the engine. At any sign of your vehicle overheating, it’s a good idea to get the vehicle checked immediately so any possible simple repairs don’t become big problems.
4. Bad Radiator
Leaks and clogging can lead to your radiator failing and any disruption in the radiator’s function can lead to overheating since it can’t pull the heat away from the rest of the cooling system.
5. Worn Out or Burst Hoses
Hoses with cracks or even holes will leave you with a leaky engine and will disrupt the coolant’s flow. Your water pump can’t circulate coolant that’s not there due to it having leaked out from one of the hoses!
6. Bad Radiator Fan
Your radiator fan pulls air across the radiator to help reduce the coolant’s temperature but a worn fan clutch or broken fan motor can’t help to reduce the temperature and will lead to overheating.
7. Loose or Broken Belts
If a belt is loose or broken, specifically the water pump belt, it cannot help maintain the correct volume of coolant flow and can lead to overheating.
8. Bad Water Pump
Your water pump is the heart of your cooling system and if it’s not operating correctly, you vehicle lacks enough pressure to propel engine coolant throughout the cooling system. Any problems with the pump from erosion, leaks or anything else can cause your vehicle to overheat.
An overheating vehicle is a sign that needs immediate attention. In most cases the original cause is a simple, low-cost repair. Unfortunately, most people ignore the initial problem and end up paying much more for extensive damage as a result.
