Identifying Engine Cooling Issues in High Temperatures: A Guide on Cooling System Malfunctions during Summer Months
As the summer heat sets in, it's essential to be aware of common causes of car overheating. Here's a breakdown of the key factors that contribute to this issue, based on the training provided at ATC Cambridge.
Increased Engine Load
Running the air conditioner and towing or hauling heavy loads can put additional stress on your engine, leading to overheating, especially in poorly maintained vehicles.
Faulty Cooling System
A cooling system in disarray can also lead to overheating. Low coolant levels, a faulty thermostat, a clogged or dirty radiator, or a malfunctioning cooling fan can all prevent the engine from cooling effectively.
Environmental Factors
High outside temperatures and heavy traffic or uphill driving can overwhelm the cooling system, especially during idling.
Maintenance-Related Issues
Old or low transmission fluid, low engine oil, and cracked or brittle hoses, broken radiator fans, and thermostat failures can also contribute to overheating. Poor airflow due to faulty belts or damaged fan clutches can further exacerbate the problem.
Unusual engine smells, such as burnt coolant, can be a sign of a cooling system issue, as can blocked radiators from debris or bugs. A radiator fan not engaging can be a symptom of a failing cooling system.
Steam coming from the hood is a clear sign of a failing cooling system.
Preparing for Modern Cooling Systems
ATC Cambridge prepares students for modern cooling systems that use electric water pumps, dual thermostats, and onboard diagnostics. Students are taught how each cooling system component functions and how to test and diagnose them.
Graduates from ATC Cambridge are equipped to become the kind of technician modern shops are looking for, able to handle both traditional and advanced cooling systems. The training also emphasises customer communication, including the importance of regular coolant flushes.
Students are taught to replace damaged fans, belts, and pumps, and to confirm thermostat functionality through heat-up tests. They are also trained to flush and refill coolant safely and correctly, and to pressure-test radiators and hoses for leaks.
