Car Overheating – Causes and Solution

Modern automobiles use sophisticated cooling systems with several heat sensors and computer-controlled electric fans to keep your engine running in any weather condition. Therefore, the chances of an overheating car in Ontario are less, but it can still happen.

How Do you know if your car is Overheating?

Your dash’s temperature gauge reaches the red zone. The information displayed on your indicator panel illuminates, alerting you that the engine is excessively hot. If your vehicle hasn’t already overheated, just a few minutes of driving like this will do it.

Under the hood, steam will begin to billow. Under your engine, coolant spills or streams onto the ground. Your engine takes a long time to cool down enough to drive again, and it may not be safe to do so.

Car overheating causes:

Overheating can be caused by several factors. Almost all of them are caused by a loss of circulation; however, they can be induced in a variety of ways.

Following are some of the common reasons for car overheating in Ontario.

Leaks in the cooling system

A cooling system leak does not cause the engine to overheat directly. Air entering the cooling system is the direct cause. The coolant level drops when there is a leak, and the air is drawn in and circulated. Because air is lighter than the coolant, it creates an airlock as it climbs to the top of the cooling system. A huge bubble that the cooling system’s coolant flow cannot pass through is known as an airlock. The cooling system effectively shuts down, causing the coolant to overheat inside the engine.

Bad Electric Fan

Car overheating when ac is on? This is probably a fan failure. Your fan motor may just burn out, and your fan may not turn on at all. Disconnect the wiring harness from your radiator fan switch to try this. If you connect a jumper wire into both contacts, your fan should turn on. Turning on the air conditioning is another technique to test the fan. When you switch the AC to medium or high speed, most—but not all—cars turn on the cooling fan.

Failed water pump

A defective water pump, which is one of the most prevalent causes of overheating, can cause overheating. The water pump, which is the most active component in the cooling system, keeps the coolant flowing. Over time, the impeller or bearing inside the water pump may wear out or fail, causing the impeller to stop rotating. Car engine overheating happens quickly after this.

How to prevent a car from overheating in Ontario?

The coolant, belts, hoses, and other things should all be replaced according to the maintenance schedule in your owner’s manual. “Replace the coolant every 60,000 miles,” is the one thing that you need to keep in your mind. This is a useful rule to follow if you want to avoid overheating problems caused by worn or aged components.


Nothing good comes out of the statement “my car is overheating”. However, a good maintenance routine can save you from a lot of trouble. Remember to keep an eye on the temperature of your engine.

Many people say their engines are “running hot,” but they don’t appear to be bothered. Even if it necessitates a trip to the repair shop, repairing a cooling problem is usually pretty inexpensive. Engine damage from a neglected cooling system and frequent overheating, on the other hand, might be costly. You may even be influenced to consider getting rid of your vehicle entirely.
