Engine coolant is generally a 50/50 mixture of water and antifreeze and it is stored in the radiator. You might be thinking, water should be cooling enough on its own, however, antifreeze actually has a lower freezing point and a higher boiling point than water.
So, when it comes to the different weather conditions, water would eventually evaporate in high temperatures or freeze in very low temperatures, whereas antifreeze wouldn’t and thus would provide more protection to your engine. Nonetheless, there’s a reason why there is a 1:1 ratio of both fluids, as both work together to form the most effective cooling system for your engine.
You’ve probably already guessed what engine coolant does, but let’s clarify its role just in case you’re confused. Essentially, this fluid has the job of maintaining the temperature of your engine, ideally allowing it to run at the optimum temperature. Without this essential fluid, your vehicle’s engine would quickly overheat and this would result in engine failure.
In the engine, heat energy produced from internal combustion must be dealt with immediately, as detrimental effects would follow if it was left to build up, which is why a cooling system is vital. Engine coolant is transported around the engine via a water pump. It absorbs the surplus of heat energy produced and delivers it to the radiator, where the heat energy is dispersed, thus, in turn, the water cools down and is carried back through the engine to repeat the process.
I think we’ve established how important this fluid is right? Now let’s learn how we can ensure our engine has the correct level of coolant…
If you’ve ever carried out a brake fluid check or engine oil check, then this process may seem familiar to you!
If you notice that there seems to be too little engine coolant in the reservoir, you will need to add some to bring the level back up.
Note: Your coolant level shouldn’t just decrease for no reason, so it’s best if you get your car booked in with a mechanic to ensure that everything is in working order and that there are no leaks.
If you’ve succeeded in checking the levels of coolant in the reservoir, then topping it up should be a breeze! Let’s continue from where we left off in the previous steps…
Now on to when it should be serviced. If you check your owner’s manual, you will find out the replacement intervals required for your vehicle’s engine. However, if you get into a regular routine of checking your engine coolant and one day you notice that it looks cloudy and contaminated, then that may be a sign that you need to drain it and replace it with some fresh coolant.
Also, if you notice a build-up of a creamy/yellowy looking gunge around the coolant filler cap, or the smell of exhaust fumes from the filler bottle, it could be a sign of the engines head gasket failing.
If you feel your engine coolant has seen better days and it may be in need of a service, contact Sinspeed today! We offer an engine coolant service as part of a major service, or it can be done separately, so book your vehicle in with us as soon as possible!
