The coolant temperature is low when the indicator is blue. It glows blue when you turn on your car because of this. When your engine reaches the proper operating temperatures, it will shut down.

Kill the A/C and crank the heat.
To lessen the strain on the engine, immediately turn off the air conditioner. the dial to the highest heat setting. Until you can stop in a safe area, this can assist draw heat away from the engine to prevent it from overheating. Even if you could become a little warm, a few minutes of discomfort are nothing compared to the cost of expensive engine repairs.
Find a safe place to pull over.
Stop the automobile and turn off the engine. Give the engine at least 15 minutes to cool. Watch the temperature gauge; when the engine cools, it should return to a normal range.
Plan how you’re going to get your overheated engine checked out while you wait (and keep an eye on the gauge). For assistance, dial a friend, a tow truck, or your neighborhood Firestone Roadside Assistance. If you need assistance with step three, we’ll send a qualified staff to tow your car to the closest Firestone Complete Auto Care location.
Check and add coolant (if you have it).
A simple top-off if your coolant level is low could assist safeguard your engine and prevent overheating until you can get the issue rectified.

BLUE TEMPERATURE WARNING LIGHT If the temperature warning light is blue and illuminates, the coolant temperature in your engine is too low to allow for proper operation. For the problem to be identified and fixed, you must take your car to the dealership.
How far is the coolant light good for?
Most people are aware that one of the most important fluids in your car is the coolant. Sadly, coolant leaks happen frequently, and coolant itself can be rather expensive. If you drive a luxury vehicle or a brand of foreign automobile that doesn’t make use of a common coolant combination, coolant is considerably more expensive.
Because of all these issues, it can become very frequent for people to inquire as to whether it is possible or safe to operate their car with little to no coolant. How long can a car operate without coolant, then?
It somewhat depends on what you mean. If you’re asking how long a vehicle will actually run without coolant in its system, the answer is considerably different than how long you can safely operate a vehicle without coolant. We’ll stick with the first response since we’ll assume that the majority of folks don’t want to take the chance of seriously harming your engine and other internal systems.
The ideal situation is to never drive your car without coolant. Running too hot can harm several internal parts, and the engine of your car generates heat quite quickly. After all, the engine contains tiny, rapidly-occurring explosions that drive the pistons, and each one of these explosions produces heat.
The automobile can probably operate for approximately a minute without significant risk of damage if you absolutely must start it without coolant. Depending on the engine, the model of the car, and the amount of work you’re asking the engine to do, you might be able to get away with running the engine for up to 5 minutes without adding coolant.
But it’s a terrible concept. Even with those incredibly brief runtimes, your car could nevertheless sustain serious, even dangerous, internal damage.
A blue temperature is what?
The blue light on your dashboard, also known as the Coolant Temperature Low Indication Light, signifies that the coolant temperature is very low.
Should you wait till the coolant light stops flashing?
The light should turn off after you start driving and the engine has heated up, even though the indicator is informing you that the fluid level is below the sensor. Check your coolant levels and the coolant sensor if your coolant light remains on even after a short period of driving.
How do coolant lights appear?
The fact that your coolant is overheating and as a result your engine is, makes this the most urgent warning light. Allow the engine to cool down and stop in a secure location. After checking the coolant level, fans, and radiator cap, inspect the cooling system for leaks.
Check Engine Light
There are too many potential causes for this bothersome little light to appear to list them all, such as malfunctioning spark plugs or O2 sensors. Ask a professional or use a code reader to identify the issue.
The voltage levels in your battery are too low. The alternator belt or the battery terminals may be to blame for this. It might also imply that your battery needs to be replaced because it is old.
Make sure your parking brake is not engaged first. If it isn’t, your anti-lock braking system (ABS) may be malfunctioning or your brake fluid may be low. Be extremely cautious when braking until the problem is fixed, and stay away from circumstances that might require an emergency stop.
The coolant light: What does it mean?
Low coolant, often brought on by a leak somewhere in the system, is indicated by a coolant pressure warning light. The sooner you address this problem, the better, as parts damage can also result from coolant leaks.
My temperature warning light is on, why?
This temperature warning light indicates that your engine is overheating because it is operating at an excessively high temperature. This should never happen if the cooling system in your car is functioning properly.
How do you check the level of coolant?
The first thing you should do if your coolant light turns on is to see if your levels are low. Initially, let your car cool off. Should you fail to do so, hot pressurized fluids may spray out of the car. Find the coolant reservoir underneath the hood, either on the front or side of the engine, and start there. It is often translucent and has lines labeled “cold” and “hot” near the bottom and top, respectively. If levels go below the “cold line,” remove the cap and inspect. If so, there is not enough combination.
A leak is typically to blame for low coolant. Hoses, gaskets, and seals on your automobiles tend to leak more as they get older. Finding and fixing a leak as soon as feasible is necessary.
When your car is in C, what should you do?
How should your thermometer generally be reading?
- Cut the air conditioning off.
- activate the heater.
- Shut off your car and temporarily pull off the road.
- Allow your car to cool for about an hour, and then add coolant if necessary (only through the reservoir, never by removing the radiator cap)
Can I simply top off my car’s coolant?
Add the proper coolant to the reservoir if the coolant level is low (not the radiator itself). Either diluted coolant alone or a 50/50 blend of concentrated coolant and purified water are acceptable. Replace the cap and tighten it until you hear a click when the coolant reaches the cold fill line. Zip up the hood.
How can I tell if my car is getting too hot?
Some indicators of an overheating engine, in addition to the presence of smoke or steam coming from under your hood, include:
- a warm to the touch hood. When the engine is running, a hood should feel warm, but if you can’t touch it for more than ten seconds without getting burned, it’s too hot.
- A red warning light or the dashboard temperature gauge. Your engine is too hot if the light is blinking or the gauge reaches its maximum level.
- a deafening ticking sound. This occurs when the oil is warmed, which prevents it from properly lubricating the components of your engine.
- On the ground is coolant. If you notice coolant on the ground, there may be a leak in your cooling system or your engine may have overheated and some coolant was spilled from the radiator’s overflow tank to alleviate pressure.
An engine overheating can be caused by a number of factors. The engine overheating might be brought on by damaged fans and blown gasket heads, a malfunctioning cooling system, or a radiator issue. It’s possible that one of your hoses is blocked or detached, which prevents the coolant from moving through the engine. It might possibly be the result of a thermostat that is jammed. Another potential offender is the AC system in your car. Have your AC system tested if you’ve recently been wondering “why is my AC not working in my car” and your car has also recently started to overheat.
