Auto Repairs and Servicing

Hello, my name is Walter. Over the past few months, I have been working on my car. I never used to think much about my car. I would just jump into it and hit the road. Things were fine at first, but soon I realised that things were starting to go wrong. Strange white smoke started to appear from the exhaust. Sometimes when I changed gear, I could hear a strange noise. Foolishly, I ignored all of this until my car broke down. When I got to the auto repair shop the mechanic repaired my car and then gave it a full service. As he did so, I began my auto servicing education.

What Might Be Wrong With Your Car's Cooling System

by Margie White

A vehicle's cooling systems is one of the most important systems under the hood, as even lightweight engines in family sedans will run very hot and will need to be properly cooled as they operate. If there is something wrong with any part of the radiator or cooling system, the engine will then suffer serious damage and may even just seize up and fail outright. If your car keeps running very hot, note a few troubleshooting tips for this system, and this can tell you what might need repair or replacement.


Leaks in the radiator itself, or in the hoses that deliver coolant to the engine, are not unusual. A hose itself is somewhat easy to replace, but if you notice steam or a hissing sound from the radiator itself, it's good to have a mechanic address this problem. This leak can usually be patched but this work takes some skill and knowhow; it's also good to know when you need to outright replace the radiator, rather than trying to patch it.

Air in the system

When air gets into the cooling system, this can interfere with the proper flow of coolant. Bleeding the air can fix this, or a mechanic might suggest draining the radiator so that he or she can note how the air is getting into the system, and this spot can be patched and the radiator filled with coolant again.

Broken thermostat

The thermostat of the car is actually a pump that pumps and circulates coolant around the engine. When it's broken, it won't be able to pump coolant as it should. A broken thermostat is actually a very common problem with cars, and is often a quick and affordable fix.

Broken fan

Along with all the coolant and water that is circulated around an engine to keep it at the right temperature, an engine will also have a fan attached that brings in cooler air from outside, and which helps to vent warm away that is trapped under the hood. The fan is typically located at the very front of the engine compartment, so a broken fan's blades may spin while you're driving just from the force of air being pushed over it; when you come to a stop, however, the fan will also stop, and the engine will then overheat. If you notice the car engine overheating when you're stopped but then returning to a normal temperature when you drive, have the fan checked for needed replacement.
