![]() ![]() Make sure your car is cold before checking your coolant level. Your coolant light may stay on if there isn’t enough coolant in your radiator. WHAT IF THE COOLANT LIGHT DOESN’T TURN OFF? Monitor your coolant light and make sure it turns off in a timely fashion. It may take a little longer to turn off on cold winter days. You can expect the coolant light to turn off after several minutes of driving in normal weather conditions. When it does, the coolant light should turn off and you won’t have to be so conscious of your driving style. These measures will avoid causing unnecessary wear and tear to your Nissan.Īs the car runs, your coolant should warm up. Accelerate gradually, rather than rapidly, and don’t try to speed up to beat traffic lights or overtake passing traffic. For these reasons, you should adjust your driving style while the blue coolant light is on. Certain automatic transmissions may also struggle to shift gears correctly until the coolant warms. When your engine is cold, the oil viscosity isn’t suited for high revving and high engine loads. Because of this, the blue coolant light will illuminate whenever you turn on your vehicle. Like other substances and components in your Versa, coolant is cold when your car starts. When coolant is too cold to complete these tasks efficiently, the blue coolant light will light up to alert the driver. Coolant also helps lubricate some parts of your Versa, including its water pump. It keeps the water in the radiator from freezing in cold temperatures or boiling over when the weather is warm. Coolant, or antifreeze as it’s often called, is a colored fluid found in a car’s radiator. ![]() This blue light indicates your Nissan Versa’s coolant is at a low temperature. Instead read on and discover what this light means and what you should do if you see it on your dashboard. If it DOES, your Switch is NOT the issue.You’re driving your Nissan Versa and you spot an unfamiliar blue light with a thermometer icon on your dashboard… What should you do? You certainly shouldn’t panic, but you also shouldn’t ignore the warning light either. Most likely area or wiring issue is at the connector.Īlternatively, you could drive with the Connector X112 DIS-connected, as long as you are SURE you have normal coolant level and no leaks, and see if warning light intermittently lights. The Coolant Level Switch is difficult to get to, at the Bottom-Rear of the reservoir, and protected from Exhaust Manifold heat by a shield, so use care (perhaps removal of shield - 3 nuts) in removing. Presumably NO warning light is "At Rest" or Normal position. Note that the three switches shown in schematic (coolant level, washer fluid level, and Handbrake) are ALL shown in "Open Contacts" position. The above is based solely on interpretation of the TIS wiring diagram, and the "convention" that switches are shown in "at rest" or usual positions. ![]() You could test the wiring by disconnecting the connector and noting if the Warning Light comes on when: (a) the wiring harness is gently manipulated or moved, (b) the two sockets of the connector are "bridged" or connected with a test wire, or (c) light flashes when harness moved with sockets bridged, ALL with Ignition ON so JBE Function is Active to process the Ground signal. Here are the Installation Location and Connector View for that Connector, X112: That means EITHER:ġ) the switch is intermittently connecting the BROWN/BLACK ground wire, connected to Chassis Ground Point X1108, to the Brown/White wire, ORĢ) there is a wiring fault in the Brown/White wire between the Reservoir Connector (X112) and the JBE (under the glovebox) ANY false ground in that Brown/White wire between the Switch and the JBE will cause the light to come on.įrom your description, it appears that YOU/Your shop have determined that the ACTUAL coolant level in the Reservoir is NOT an issue. The way it is SUPPOSED to work is to provide a Ground Signal to Pin #54 of Connector X14271 at the JBE (Junction Box Electronics) Module IF the coolant level is low, and THAT ground signal causes the Warning Light on the Instrument Cluster to come on. You have a Coolant Level SWITCH (NOT Sensor -) in the Coolant Reservoir. It stays on and within 4-6 seconds, it disappears. For the last 2-3 months, the coolant light on the dashboard has surfaced intermittently. ![]()
