Made up of 5 main components, the cooling system can be one of the more temperamental systems in your car. This system manages temperatures of over 1000 degrees Celsius. and when your car runs hot, you run the risk of damaging the components of the engine itself. More often than not those repairs can be quite costly, so a little preventative maintenance on your engine cooling system is money well spent.

Telltale signs that your engine’s cooling system may not be functioning properly are as follows:

I smell a sweet/offensive odor coming from my engine. Is this normal?

If you have recently refilled your anti-freeze, then there may be residue on the engine and when the engine’s running hot the smell can become more apparent. Aside from spilled anti-freeze there are a few internal issues that produce an offensive or sweet odor. Leaky or cracked thermostats in conjunction with damaged water outlets tend to be the culprit of strong or offensive odors coming from your car’s engine. If the water outlet stops working, coolant will leak out and affect the surrounding area.

Why is smoke/steam coming from under the hood?

If you notice steam coming from under your hood, there’s a chance your engine experiencing a coolant leak. The radiator hose connects your thermostat outlet housing to the water pump inlet housing and when compromised can cause coolant leaks. When coolant comes in come in contact with the high temperatures of the engine, steam forms. Be sure to check this hose every 9000 miles or once a year.
