What does it mean when it says engine coolant low?
A lower-than-normal level of coolant means that the coolant has less time to cool in the radiator before being pumped through the system again, resulting in inefficient engine cooling. As cars get older they may start to leak coolant, and it is important that you regularly check your coolant level.
How often are you supposed to put coolant in your car?
every 30,000 miles
A typical mechanic will recommend changing coolant every 30,000 miles. But many will tell you, changing the coolant is not even on their radar. An owner’s manual might recommend changing the coolant/antifreeze after the first 60,000 miles, then every 30,000 miles.
Is it okay 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.
Can a low coolant cause a check engine error?
Low coolant in the radiator of your car can trigger the malfunction illumination light (MIL), also known as the “check engine” light.
What should coolant temp be when car is cold?
If you have a scan tool with live data, check the engine temperature when the engine is cold, it should be close to outside temperature. Drive a car for 10 minutes and check the engine temperature again, it should be close to 180-220°F or 82-105°C. See the photo. Without a scan tool, the engine temperature sensor can be tested with an ohmmeter.
Can a low coolant sensor cause a PCM error?
The PCM and Low Coolant. Low coolant can affect the internal temperature of the engine, which is protected by the antifreeze. When the coolant is too low to effectively protect the internal temperature of the engine, the engine coolant temperature (ECT) sensor will provide a false reading to the powertrain control module (PCM).
What’s the best way to check your coolant level?
Make sure your vehicle is on level ground for accurate readings. You’ll also want to wait for it to completely cool down, as your radiator and coolant can become extremely hot. Open your hood and locate your radiator and coolant reservoir.
