A blue engine coolant temperature light only indicates one thing: that your coolant, or antifreeze, is too cold. In fact, the temperature is so low that it is possible for your radiator to get too cold, thus resulting in your engine freezing up and not being able to start.
When it's blue, it means your motor isn't quite at the operational driving temperature yet. In other words, the engine needs to heat up. For this particular reason, it's advised that you wait until this blue light turns off before you drive anywhere. This engine coolant light can turn another: Red.
The Blue C means that your Honda Civic has been certified by the CARB. This certification ensures that your Honda Civic meets all the California emissions requirements.
The Blue Engine Coolant Warning Temperature Light comes on when you start your Subaru, it just means that the engine is not warmed up yet. You'll most likely see this light every time you start the car. Until it goes away though, you should drive gently.
It actually represents a thermometer-which means your car is getting too hot. Possible causes could include a coolant leak, a bad water pump, bad thermostat or more. Pull over as soon as possible if you see this, as it can be very dangerous.
The Traction Control warning light will typically have the abbreviation TC or TCS. Many other models will use a symbol that looks like a car with squiggly lines underneath it. Many traction control systems will illuminate the warning light when the system detects a loss of traction such as in snowy or rainy weather.
A car's engine running on C is no big deal. It'll run forever.
Blue Antifreeze is a full concentrate which meets BS6580 and contains the same pure ethylene glycol and anti-corrosive additives as the Red. Its application is for protection for up to a maximum of 2 years.
No! You should never mix coolant fluid with regular tap water. Tap water contains minerals that can form deposits inside the radiator and cooling system passages of your engine. Use only pure, distilled water.
Your engine could overheat.
Coolant helps pull heat away from the engine. So, without enough coolant, the engine could overheat or seize up. Continued use of an overheated engine could lead to permanent damage, such as pistons welding to the cylinders.
The indicator is telling you that the fluid level is below the sensor, however, once you start driving and the engine heats up, the light should go off. If your coolant light stays on even after driving for a few minutes, then it's time to check your coolant levels and the coolant sensor.
What causes the coolant warning light to come on? The most common reason for the coolant light to become illuminated is simply that the coolant level is too low. There may be a floating sensor in your coolant tank that triggers the warning light when the level drops. You may need to book a coolant change.
Phosphated HOAT (P-HOAT)
This coolant comes in pink or blue colour. Phosphated HOAT uses phosphates along with organic acids to prevent corrosion. This coolant is compatible with the models from carmakers like Hyundai, KIA and Honda.
If your coolant level is too low (below or near the lower mark), top it up using a 50/50 mixture of water and antifreeze (for normal driving conditions), or pour pre-mixed antifreeze straight into the reservoir. You can use clean tap water in an emergency, but antifreeze should be added as soon as possible.
If you were to just use water rather than the coolant mixture, high temperatures inside the motor would easily boil that water and cause it to evaporate, meaning you'd quickly have no coolant at all and the engine would easily overheat.
Can you top your coolant up with water? Coolant should only be topped up with water in case of an emergency when the coolant liquid level is lower than it should be. While topping up with water will help you get safely to the nearest garage and identify any issues, it shouldn't be relied upon.
Flushing the coolant and replacing it with fresh fluid every two years or 30,000 miles is a good rule. While you perform this service, inspect the hoses and radiator cap for wear.
“These days, there's no real reason for a coolant manufacturer to use a certain colour, so it's not easy for you to know what chemicals are in the coolant just by seeing whether it's blue, green, yellow or orange.
Overall, mixing the green and orange coolant can damage your cars' coolant system.
A “C” reading on a car dashboard gauge, which indicates a cold engine, is most common during the winter, especially during subzero temperatures. This can even result in not being able to start a vehicle. One way to address this is to repeatedly turn on and off the ignition.
C. Category C refers to large goods vehicles, meaning you can drive anything over 3,500 kg (with a trailer up to 750kg MAM).
A category C license allows drivers to drive vehicles over 3.5 tonnes, but must not exceed 32 tonnes. Category C (or Class 2 as they are otherwise known) licences typically cover a vehicle with a cab and trailer fixed permanently together. In other words, what we would consider a 'standard lorry' or a rigid vehicle.
The C programming language is a procedural and general-purpose language that provides low-level access to system memory. A program written in C must be run through a C compiler to convert it into an executable that a computer can run.
