There are several different things that could cause the coolant to leak out: a bad radiator, a faulty water pump, any of the coolant lines, etc. Just add more when you get a chance, especially in winter when you will need it to wash the salt off your windshield in order to see.
It is usually warning you about a headlight or tail light, but on more advanced systems, there might be warnings in place for fog lights, tag lights, and turn signals as well. Some cars do not have any indicators to tell you that the cruise control has been activated, others use symbols like these. Your owners manual should tell you what maintenance is recommended when, which should give you a good idea why the light is on and what needs to be scheduled for your car.
15,000 miles is way too much for even synthetic oil, let alone the filter, which is the same whether it’s filtering synthetic or regular oil. 3 months, especially if you're not making any long trips, as the oil does not heat up enough to burn off contaminants in the oil with short trips. Until the 1990s, the charging systems in vehicles were controlled by some form of a voltage regulator in or near the actual alternator.
If the charging system warning light comes on while you are driving at night, you have very little time left before the engine dies. Via email, text message, or notification as you wait on our site.Ask follow up questions if you need to.
First of all the oil pressure light on the dash shouldn't even have power with the key off, so check the PCM fuse #8.

Continuing to drive a car that is overheating can destroy your engine in a matter of minutes! Continuing to drive a car that is overheating can be catastrophic to your engine and can damage it beyond repair after only a few minutes.


Have your technician diagnose the problem as soon as possible to avoid the potential of causing damage to your transmission.
Again, the best idea is to have your technician tell you whether it's safe to keep driving or not. Wait for the light to extinguish before continuing to drive, as continuing to allow your trans fluid to overheat could cause costly and possibly irreparable damage to your transmission.
In other cases, it could be a major fault, and continuing to drive the car could cause further damage.
Conversely, when the cruise control has been deactivated, these symbols will no longer be visible in your instrument cluster. Finally, when a red light appears in this field, it is telling you that service is overdue. Fill out the form and describe the icon you're asking about, as well as any symptoms that went along with it. The light was connected to the battery and when the key was turned, the light would ground through the alternator.
When you start the engine, the warning light should stay on for 1 to 2 seconds and then go off and stay off for the entire time the engine is running. This is because the vehicle is operating in a "total loss" condition, meaning that the battery is not charging so all of the available voltage will drain out of the system.
It should only have power with key on, not with key off or out.For that wiring diagram, click here.
It is nice to know that this service is here for people like myself, who need answers fast and are not sure who to consult. I liked that I could ask additional questions and get answered in a very short turn around. Not only did you answer my questions, you even took it a step further with replying with more pertinent information I needed to know. When the engine was started and the alternator produced voltage, the voltage would travel throughout the vehicle's electrical system, including back up the wire that lead to the light.
This means that the voltage for the charging system is meeting the requirements set either by the voltage regulator or powertrain computer, depending on the design and model year of the vehicle.


It is best to turn off all the unnecessary electrical devices such as the radio, air conditioning, and heater. When the charging system light had two sources of voltage reaching it, it no longer had any ground and would be turned off. The vehicle may only drive for a few miles, so try to find a safe place from where it can be towed to a qualified repair shop. If the charging system light comes on during the daylight hours, there may be a bit more time because you aren't using your head lights, which are a major drain on the system. This is necessary because the newer, networked on-board computer systems needed "cleaner" and "noiseless" operating voltage so that the accuracy of the sensor data and learned adaptation stayed within the specified tolerances.
This is because most of the charging systems need to "see" the warning light in the charging system or they will not properly allow charging system voltage into the system.
Then disconnect the negative battery terminal and hook the 12-volt test or voltmeter with the positive test lead on the disconnected negative battery cable and negative test lead on negative battery post. In these newer vehicles, the charging system light is illuminated by a command from the powertrain computer when it sees an irrational difference between the desired system voltage and the actual system voltage. A light on the 12-volt test light or voltage reading on the voltmeter indicates that something is draining the battery. If so start by unhooking the small wires at the alternator and see if the test light goes out or dimmer or if the voltmeter drops in voltage, hopefully to zero. If the 12-volt test light goes out or the voltmeter now reads zero or less than 0.2 volts then you have found the short. If the voltage is not zero on voltmeter or test light does not go out, the short is somewhere else.
