Frequently Asked Questions
As coolant fluid circulates through the engine, it absorbs heat. That hot coolant then flows into the radiator, where it is spread out over a large surface area to allow air to pass across it, cooling the liquid, and therefore the engine. When driving, the natural airflow cools the narrow tubes and fins of the radiator. When stationary, a fan activates to keep that air blowing. Ultimately, what a car radiator does is prevent the engine from overheating.
There are several indicators that your radiator is failing. An overheated engine – indicated by a warning light on your dashboard or a dreaded head of steam emanating from the engine compartment – is the primary symptom of a failed radiator. Lack of coolant, discoloured or rusty coolant, or signs of leaking coolant are early red flags. Radiator hose leaks are an obvious sign, but keep an eye out for subtle ones too; if the heating system in the car interior isn’t working (it relies on the hot coolant circulating around the engine to warm the air it pumps through the vents), it’s time to bring your car into Cox Auto for a service.
Driving a car with a cracked radiator is extremely dangerous. The further you drive under such conditions, the greater the risk of catastrophic overheating and a costly repair bill. If you’ve identified a crack, contact the team at Cox Auto for immediate advice and repair.
The cost of radiator repair varies based on your vehicle’s make and model and the extent of the repairs needed.
