Increasing The Anti-Freeze RatioĪ higher ratio of anti-freeze will just make it freeze at a much lower temperature. The resulting mixture is called coolant. Increasing the amount of coolant (going over the MAX mark) will reduce the pressure of the system and therefore reduce the cooling abilities of the system. What you add to the water is anti-freeze. Make the nozzle spray slightly. The radiator fins are thin metal and pressure washers can bend or even cut the radiator fins. Start about 2 meters away and slowly get closer until the water cleans the radiator effectively.

If you use a pressure washer, don’t get too close and don’t have it on full jet. If you use a pump spray bottle, use hot soapy water (not boiling), dial the nozzle to a jet and get in as close as you can to blast the crap out from the radiator fins. The 2 good options are a pressure washer or one of those pump up spray bottles. I don’t expect you to sit there with a toothbrush and a pipe cleaner cleaning out all the fins. You don’t really even need to take the front panels off.

Keeping Your System EfficientĬheck that your coolant level is within the MIN and MAX mark on the expansion tank. Make sure that your coolant ratio is ok for the climate of the country you are driving in. Keep the radiator clear of bugs and mud that would block it up and reduce air flow. That’s when metal starts to overheat and warp causing headgasket failures and seized engines. In this small temperature range, this process is still cooling although it’s far from efficient.Īs the heat increases, the water explodes into micro steam bubbles which creates a lot of turbulence in the water. This action actually starts to corrode the metal parts that it touches and in those areas you will get nearly no cooling at all. The coolant will only be boiling in the engine water galleries around the cylinders and the exhaust valves. The water/coolant boils which creates a layer of steam between the hot metal of the engine and the coolant. This steam passes its heat into the water and condenses back into water. It doesn’t get to this temperature and immediately turn the whole lot into steam so you have time to turn the engine off when you hear the alarm. The smart coolant, if mixed correctly (50:50), the correct level and the coolant system is pressurised properly, will not start to boil until it reaches 122✬ (252✯). That’s 158º and 212º Fahrenheit.Īt 105º Celsius (221º Fahrenheit), the front radiator fan will come on to help the air flow across the radiator which should cause the temperature to level out or reduce.Īt 120º Celsius (248º Fahrenheit) you will get a coolant temperature warning alarm. If you hear this, turn the engine off as soon as you can to prevent any damage. You can expect, depending on the outside temperature, your style of driving and the amount of traffic, to see an operating temperature between 70º and 100º Celsius. They do this by using a large and efficient radiator compared to the size of the engine and the amount of coolant in the system. Like a London taxi, it is designed to sit in traffic but not over heat. The smart is touted as a city car and it is designed as such. The engine is only small so it has problems maintaining a hot running temperature in cold climates but also does a very good job of keeping cool in very hot climates. It varies wildly depending on the climate of the country you are driving in. There is no proper smart operating temperature. If they don’t have the information, they have nothing to worry about. Maybe that’s the reason why smart removed the coolant temperature gauge from the American smart. I can only assume that historically, their American built cars either run a lot cooler, bigger displacement engines run cooler or smart engines run hotter than normal. They are obsessed by temperatures and seem to instinctively know what temperature their car should be running. They are all from American smart owners who have recently bought some kind of OBD gauge. I have had this question (or statement) quite a lot recently and I have noticed a trend.
