Is there a light for low coolant?
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. Low coolant levels are usually caused by leaks, either in the reservoir or somewhere in the lines.
Is it ok to drive with low coolant?
The biggest concern of driving a car with low coolant levels is the potential for overheating the engine. If there’s not enough coolant present, temperatures can rise to potentially catastrophic levels, increasing the risk for a blown head gasket, warped cylinder head or cracked engine block.
How far can you drive with coolant light on?
But it depends on the level of the coolant. If the coolant is low but above the minimum mark, then you are still fine to run the car for a few days, but if the coolant is below the minimum mark, please do not even try to drive your car like that so you don’t knock your engine. You need to top up the coolant.
What kind of coolant does a Toyota or Lexus use?
Your Toyota or Lexus, depending on the year, came with one of two types of coolant from the factory.

It is important to keep your coolant in top shape.
What should I do if my coolant level is low?
If there is a rise in the temperature gauge, check your radiator for coolant levels. You can add water until it overflows and continue observing the gauge. If the problems persist, then you can be certain that it is coolant leakage. It is dangerous driving with low engine coolant as it will destroy engine components.
What does it mean when your coolant light comes on?
Your coolant light might be signs of a more major engine problem. When you get a crack in the block or the intake gasket you will leak coolant and oil, usually slowly at first. You may not notice the difference at first, thinking that your tank is full.

This belt connects to the engine crankshaft, but this part is subject to corrosion and leaks. The water pump itself can also suffer from external damage that leads to a leak. Either way, if the pump isn’t working right, the coolant can’t move properly, which will cause the engine to overheat.
When does the low coolant level warning light go out?
When you start the engine, the low coolant level light should come on for a second or two and then go out. If it doesn’t go out, either the coolant level is too low or there is a problem with the sensor system.
