Why does my coolant gauge stay at C?

Why does my coolant gauge stay at C?

Not open for further replies. So I noticed yesterday that my coolant temperature gauge stays at C, even after driving around for 30 mins. I also noticed that my fans run constantly, even in 53 degree weather, and with me running the heater to see if that would shut them off.

How can I tell if my radiator fan is working?

When a radiator fan works it usually makes a whirring sound that is easily noticeable. However, the radiator fan does not always start spinning on ignition. The ECU signals the radiator fan to work at the precise time. So, do not worry if the fan doesn’t immediately start working. Visually check the fan if you don’t hear its noise. 1. Broken Fuse

Why do you need a radiator fan in a car?

To stop the engine from overheating, we take the help of coolants that flow through a radiator into the engine. The radiator’s job is to keep the coolant cool so that when it returns back into the engine, it is able to absorb more heat. A radiator fan is thus used to keep the temperature of the coolant in check. Thus, it has an important job.

Why are the fans not running in my car?

Change the T-stat. and while you are there change the sending unit as well. Most likely cause is the T-stat. Change it soon though, you don’t want to burn up the fans. I think that is what happened to mine. I waited about 3 months to change mine out and I could never get the A/C to work after that. I think it was because the fans were not running.

Is there a way to test a radiator fan?

You can test the electrical radiator fans by taking a wire from the car battery, unplug the radiator fan connector, and put 12v+ and ground into the connector. This is the fastest and easiest way to test your radiator fans. Because the radiator fan is often drawing so much power, there is often a relay that is powering the coolant fan.

What does it mean when your radiator fan is not working?

This is what we call a blown fuse. A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan.

What to do if your coolant gauge is not working?

Run the engine for about 20 minutes to get it up to temperature or until the gauge says you’re running hot. Open the hood and take a look at your coolant tank. Most tanks should have two lines marked on them, the top one reading as “full/hot” or something very much like that. Your coolant should be at that line after 20 minutes of running.

What does it mean when your temperature gauge is not working?

The temperature sensor/sending unit is faulty. If this is the case your sensor will be reading the coolant temperature incorrectly and sending the wrong signal to the gauge. This could work in either direction and read as cool when it’s running hot or hot when it’s running cool. A malfunctioning circuit in the temperature gauge
