Why is my coolant light on but my coolant is full?
Your sensor may fail or it may simply give a bad reading. A bad coolant sensor may cause a decrease in fuel efficiency or it may also cause the vehicle to fail your emissions inspection. It is likely that the problem may be a loose, corroded, or faulty connection and not a problem with the sensor itself.
Is it OK to fill coolant to max line?
Fill the reservoir to the MAX line. Do not overfill it. The coolant mixture expands as it heats up and needs room to do so. Replace the cap.
Why is my coolant level high?
The coolant inside a car’s cooling system drastically fluctuates in temperature, which means its volume also changes. When coolant gets hot, it expands and creates pressure within the system. Once the radiator is completely full, this expanding hot coolant will overflow into the reservoir.
Is overfilling coolant bad?
Coolant expands as it heats and contracts when it cools. The extra space prevents damage to your engine and hoses. In worst case scenarios, overfilling your antifreeze tank can lead to electrical damage if overflow comes into contact with engine wiring.
How to see the min / max on the coolant overflow tank?
The min/max lines are about a foot down a narrow dark crevasse, If the light into the engine compartment is just right I can barely make out where they are, but cannot tell where the coolant level is at all. The tank itself is a bizarre twisty shape so I can’t just look in there with a flashlight to estimate the height.
How to check the coolant level on this car?
What is the trick for checking the coolant level on this car? The min/max lines are about a foot down a narrow dark crevasse, If the light into the engine compartment is just right I can barely make out where they are, but cannot tell where the coolant level is at all.
What does the mark on the coolant reservoir mean?
Read on, to find out. It is known that the coolant reservoir tank usually has two marks. One of the marks denotes the coolant in the reservoir when it is hot, and the other indicates the coolant present when it is cold. Generally, when there is too much coolant in reservoir tank, it gets expelled out through the overflow hose.
Where is the coolant cap on a radiator?
When it was last in the shop they said the coolant level was OK, but when I take the radiator cap off when it is cold the fluid level is well below the drain tube, just about at the bottom of the “neck”, which does not look right to me. I wouldn’t worry about the level in the neck, as you’ve described it.
