Kenworth Coolant Level Sensor Bypass – How It Is Done

Looking to do a Kenworth coolant level sensor bypass?

Your coolant level sensor makes use of a movable floating device, as well as a reed switch. The switch is capable of sensing once the radiator has a low level of coolant. 

During this point, you will be notified of a low coolant level. Thus, you will be able to see the light showing up on your dashboard, letting you know of this low coolant issue. The coolant level sensor is found on the bottom of your expansion tank or on your radiator.

The sensor works with a type of float containing a ring magnet. There is a reed switch inside, then the ring magnet closes it when there is sufficient coolant in your radiator. But when the coolant level is low, the float will follow the level. It then removes the reed switch from the magnet, which contracts your reed switch until it opens.

Afterwards, the coolant light would light up, so you are notified and be able to take action. 

But if you have just put the right level of coolant in the tank and yet the warning light switches on, this means your coolant level sensor has an issue. This is why you need to have a mechanic check for problems and get the sensor replaced, in case this is the cause of the issue.

Over time, the coolant level sensor may fail. There are signs that a replacement may be required such as the coolant light turning on yet the reservoir tank is currently full, or the you have a low coolant level yet without any warning lights illuminated.

Do keep in mind that your coolant level sensor is essential in ensuring the proper operation of your engine. You need to maintain the ideal coolant level to prevent overheating issues and damage to the engine. Thus, a coolant level sensor problem needs to be addressed immediately. 

But if you have a coolant level sensor that sends incorrect data to your vehicle’s computer, this can lead to further problems. Among these are poor performance and reduced fuel economy. So, it may help to know how to do a Kenworth coolant level sensor bypass to make sure your vehicle runs at its best.

The coolant light may stay on, and this usually means that your coolant level sensor is acting up. Once there is a short to the sensor, this keeps the coolant level light on. This is a serious concern since having an illuminated coolant light switched on permanently cannot alert you once the coolant level has actually dropped down.

If you have a low coolant, you may also notice an issue with your coolant level sensor. The light usually turns on when the wire or the sensor itself has a problem. This sensor is primarily intended to detect a low coolant level. Thus, having a low amount of coolant in the reservoir that is not turning the light on can mean there is a wiring issue to be fixed.

And when you have an overheating issue with the engine, it can also mean that you have a problematic coolant level sensor. Again, there are many reasons why your engine may overheat – some of these causes may have nothing to do with your sensor. But if it is indeed because of your sensor, then you will have to get this component repaired or replaced.

Although your coolant level sensor does not have a significant role in your engine’s drivability or performance, it is important in keeping your engine in good running condition. It also prevents overheating, which is crucial for the lifespan of your engine. With that being said, if you regularly encounter coolant level sensor problems, you need to have this issue checked by a technician right away. 

Sometimes, a simple coolant level sensor bypass can help fix this issue temporarily. As we have mentioned earlier, you can find the coolant level sensor on your radiator. When you look at the engine from the front portion of your vehicle, it is on the left side. You can see a clip that holds it in your radiator.

To do a bypass, simply remove this clip and then pull your sensor out. This will cause you to lose coolant, which is why you should swap this out really fast or consider draining some of this coolant out. 

After you have installed the brand new sensor, put the clip to secure your sensor in place. Reconnect the wires to your sensor and then crank the engine. But be sure that you have a full coolant level. Then, this should be able to solve your problem.

Wrap Up

But for safety purposes, we do not recommend doing a coolant level sensor bypass. There are some dangers that may arise, which is why it is not ideal at most cases. If you have an issue with your coolant level sensor, it is better to have it replaced with a new one instead of bypassing it.
