An Overview On Auto Engine Cooling

Buying and installing your own auto parts can save you a great deal of time and money, as long as you know what you’re doing. Keeping your vehicle in tip-top shape is critical, and general maintenance should not be ignored. This applies to the car or truck’s cooling system as much as it does to things like tires or brakes.

The cooling system cycles coolant from the radiator through the engine. This helps maintain safe, consistent running temperatures that keep your engine working properly.

Once coolant or anti-freeze is added, the radiator breaks up the heat with a cooling fan. The engine’s thermostat is supposed to control the temperature and regulate how much coolant or anti-freeze passes through your radiator. The engine’s fan clutch then senses the temperature of the air exiting the radiator and pulls up air through it. If your car is a front-wheel drive, it probably also has a cooling fan close to the heater return hose.

The first signs of a problem with your vehicle’s cooling system might include the temperature gauge starting to climb. Your warning lights might also go on, and you could have trouble starting your engine. Look for signs of leaking from your radiator, too. If your car has steam coming off its hood, it’s overheating and needs repairs immediately.

It’s important to check your fluids according to the manufacturer’s recommendations, but you may also have to replace parts from time to time to prevent your engine from overheating. Sticking with manufacturer-approved parts (like original equipment manufacturer or OEM products) is important if your car has a warranty; otherwise, you might be able to save a few dollars on compatible aftermarket parts.

Auto part product descriptions often tell you what kind of vehicles they are compatible with. For large parts like coiling fan clutches, you are also safer sticking with manufacturer parts, even if your warranty is expired. You have more flexibility with inexpensive things like radiator fans.

When in doubt, check with an expert in the repair of your specific make or model. Never attempt to repair something on your car or truck if you are unsure exactly what you are doing, as this can be a safety concern both during and after repairs.

The Auto Engine Cooling Buying Guide

  • If you lack mechanical skills, do not attempt to replace parts yourself.
  • Never add coolant to a hot engine.
  • Have your radiator flushed every 40,000 miles or so. Check your owner’s manual for more specifics.
  • Some mechanics will allow you to purchase the replacement parts for your vehicle on your own to save money. They will then install those parts for you. This isn’t always the case, but it can’t hurt to ask.
  • Follow the manufacturer’s recommendations for tune-ups. These guidelines will explain how to check and top off your fluid levels, as well as how to check the engine.
  • If you notice that your temperature gauge keeps running high, do not put off getting the car checked. People who ignore this kind of problem with their vehicles often end up with much bigger ones.
