When the weather begins to heat up, ugly problems such as car engine overheating can begin to surface, causing anxiety and inconvenience you could certainly live without. Hot weather and heavy traffic can magnify any existing problems in your vehicle’s cooling system. If left unchecked, can lead to serious engine damage and hefty repair bills. In order to help minimize the risks of overheating, there are a few key points of maintenance and inspection that should be looked into.1. Catch up on Maintenance
Proper maintenance is the key to eliminating car overheating causes before they appear. Ensuring your coolant has been changed as per manufacturer’s recommendations, and that the coolant to water ratio is as close to recommended specs as possible, is vitally important to both proper cooling and the prevention of corrosion. In addition, making sure your cooling system is free of air and your water pump and thermostat are working properly will help prevent any future problems. When adding water or coolant to your engine, always make sure to use a distilled water, as normal tap water can cause an increased chance of corrosion, as well as mineralization of the cooling system.2. Inspect your Radiator and Cap
A radiator that shows excessive damage to the fins, or one that is excessively dirty will have trouble radiating heat. This in turn can greatly reduce the engine’s ability to shed excess heat. By cleaning any paint over spray or dirt and bugs from your radiator, you can improve cooling efficiency by a significant margin. The radiator should be uniformly warm when in use, so any cold spots may be a sign of an internal blockage. In addition to the radiator, make sure your radiator’s cap is functioning properly. Boiling sounds during normal operation may be a sign that your cap is not maintaining adequate pressure to prevent boiling, and boiling can vastly reduce the effectiveness of your radiator.
3. Check your Fans
While fans may do little to nothing during extended trips at highway speeds, they are invaluable should you be stuck in traffic, as they are the sole source of airflow when your vehicle is at a stop. Allow your car to idle and listen for the fans to switch on after a few minutes. If they do not, you may require a new switch or new fans themselves to help fight off overheating.4. Downsize your Intercooler
In hot climates or heavy traffic, a overly large aftermarket front-mount intercooler can have a substantial effect on the overheating of your vehicle. Your radiator requires ample airflow to transfer away heat, so if an overly large and hot intercooler is blocking this airflow, as well as increasing the amount of heat it is forced to deal with, overheating issues will almost certainly result.Having a car overheated in the middle of summer can be a horrible thing to experience. By keeping up on proper maintenance and ensuring everything is working as designed, you can almost completely eliminate most of the common problems of overheating.
