Overheating is a common problem among the older cars which used to have steel engines, they got heated up quickly, but the current scenario has changed drastically with the use of modern technology in engines. But, you can never be 100% sure in the case of machines. As there are various factors that contribute to overheating in cars, Newman’s Auto brings you the following list of preventive measures that can be helpful for you.
1. Keep a regular check on radiator caps
The radiator caps are specially designed to keep the radiator cool, maintaining an optimum pressure in the system, not allowing the coolant to boil. But when the cooling system fails and undesirable pressure is formed inside the system, it makes the coolant to boil. Boiling of coolant increases air and bubbles which aren’t good at conducting heat. Hence, the generated heat cannot be transferred out from the engine, causing overheating in cars.
2. Decrease in coolant levels
One of the main reasons for overheating in cars is a decrease in coolant level. This may be either due to leakage in radiator, water pump, cylinder heads or the freeze plugs. Another reason for low coolant level could be irregularities in servicing of your car. Keep the radiator full with coolant and keep a regular check on the levels. In case of emergency, you can fill the reservoir with tap water which might prevent your car from overheating. But, replacing it with proper coolant is advisable as tap water is only a temporary solution.
3. When the electric fan fails
An unexpected failure in electric fans can cause your car to overheat. The fan provides cool air to the radiator and keeps your car at an optimum temperature, preventing it from exceeding the heat in your car. A small stone, causing a blockage could be the reason for electric fan failure. You may need to contact a local mechanic for assistance to resolve the issue.
4. Issue with the water pump of your car
Water pump of your car gets damaged if there is a breakage or a seal leakage occurs inside the pump which ultimately leads to overheating. The only solution is to replace the water pump once it is damaged as it cannot be fixed or repaired.
5. Cleaning your car’s radiator
Any kind of adulterants around the radiator can cause a steep decline in cooling of your car either new or old. Hence a simple cleaning of the radiator both from inside and outside is necessary in order to keep the system going for long. The inside cleaning can be done with every coolant change by flushing the old one and by draining it with water, preferably distilled water which could help in preventing rust deposits.
