How can I find out the coolant temp in my car?

How can I find out the coolant temp in my car?

If you have an OBDII scanner, you may even be able to graph coolant temperatures in your app and track them that way. The best place to start in comparing your vehicle’s normal engine coolant temperature to see if it’s correct is with your thermostat setting.

What should the temp of the coolant sensor be?

Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.

Can a bad coolant sensor cause a car to not start?

Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.

What should the temperature of an engine cooling fan be?

Engine cooling fans may engage at one speed or multiple speeds and may kick on anywhere between 180 and 220 degrees.

When does the coolant temperature warning light turn on?

The coolant temperature warning light turns on when your engine is sensed to be too hot and is at risk of damage from overheating. Is it safe to drive with the coolant temperature warning light on?

What should I do if my coolant level is low?

Once the engine has cooled, check the overall fluid level of the coolant. If the level is low, you can add just water temporarily so that you can drive somewhere to get the car checked out. Keep in mind that a low coolant level means a leak is present which needs to be remedied at the earliest.

What should I do if I Can’t Read my OBD code?

If you’re scanning your car’s computer for OBD (on-board diagnostic) codes and getting nothing in return, there are some things you should check before you give up and take your car to the shop.

What’s the normal operating temperature of a car?

While we don’t have your vehicle specific information, normal operating temperature for most vehicles can range between 190-220 degrees Fahrenheit. Thank you! -BDP

Is there a temperature gauge on my car?

One vehicle we test drove did have a temperature gauge closer inspection the gauge stayed centered even though the vehicle’s actual coolant temperature ranged from 140 degrees up to 230 degrees! So how can you be sure of your engine coolant temperature? If your car is older than 1996 it will have an OBDII port.

How to test the coolant temperature of an engine?

1 Unplug the sensor electrical connector. 2 Get the engine surface temperature using an infrared thermometer or suitable cooking thermometer. Take the engine temperature on a location near the coolant temperature sensor. 3 Take a note of the temperature reading.

How does a bad coolant temperature sensor affect engine performance?

You can do it at home using a digital multimeter and a cooking thermometer. A bad engine coolant temperature sensor affects engine performance: It may cause a constant lean air/fuel mixture, causing the engine to stall or idle rough. Or it may cause a constant rich air/fuel mixture, causing an increase in emissions and fuel consumption.

How do you reset the odometer on a car?

Press & hold the odometer trip/reset button. Turn the key to the accessory position while continuing to press the button, but don’t start the car. ( alternatively, you can go ahead & start the car while pressing the button. I do it w the car off first, then w the car on ).
