Before I found your video, I had already learned that sometimes replacing the reservoir is the solution to this common KW problem. I knew a magnet was involved. I still didn’t know exactly how it worked until this video. Thanks.
I had a similar issue with the low coolant light and alarm staying on. Turned out the electrical connection on the sensor probe to the wiring harness was bad. I bent the prongs on the sensor to make better contact and problem solved. 10 cents solution to a $500 problem.
@@godhelp7020 Yes, it worked for me. Before I replaced it, I bought an aftermarket sensor, and it worked for 2 months. Then I bought the original one at the dealer and it worked for about a week. This thought me that I had to buy the whole reservoir.
Thanks for the video, today I had a problem with my sensor and was wondering what the deal is, for now I ended up unplugging it to make the alarm and light go off, thanks so much God bless
Could be the plug that needs to be replaced. I'd try that first or the sensor before doing the tank. Could just leave it unplugged like I'm doing. My truck won't debate because of it
I would use a voltmeter to make sure power going to sensor,then with coolant full in reservoir if engine light ON saying low coolant then unplug the sensor from harness,(dont pull out from reservoir it self) engine light goes out then that's the issue
I think it works bc when I unplug the sensors a new code appears but when I plug again the code can be deleted but the code 2448 still flashing, maybe the magnetic is stuck or dirty, do you have any way to test before I buy a new reservoir?
@@pedromunoz8666 sorry messed up my explanation...if the sensor has power to it then probably the magnet and need new resviour.. If you buy the reservoir try swapping out sensors 1st as they come right out(coolant will spill out if full)and see if that stops the issue and it will be sensor if issue still there then its resivour... There is ways to bypass the sensor but most likely it's going to be a reservoir magnet that is no good so always reading empty
Another typo..lol...*if swap out with new sensor and issue still there its the magnet...if issue go away then its sensor n can return resviour And just by sensor
I bought a 2013 T660, it's an ex Melton flatbed company truck with some upgrades the second owner had an intake and exhaust manifold from Pittsburgh power with an ECM tune installed right before I got it from him. Well for 3 months I chased the low coolant ding until finally after 2 tanks and 3 sensors I pulled the sensor out and I duct taped a magnet to it, viola! No ding only problem is no dummies' you have to open the hood and check the coolant level yourself oh and watch the coolant temp gauge. Now the truck has no check engine lights on, it passes emissions and goes like a raped ape!
Good idea to try. Would you try to stick the magnet onto the rod that goes into the reservoir towards the upward top of the rod or to the bottom of the rod closest to the plug on the sensor?
So my truck went into DERATE due to a coolant warning that shut the entire truck down, I replaced the coolant level sensor , but now the coolant light stays on while truck is idle, but once the truck starts to drive it goes away and comes right back once I stop even at a traffic light

Thank you
Thank you for this video I have to remplace the reservoir
Is that works for you? I'm having the same issue

My peterbilt just starting doing this. How long can I drive like this?

Mine is doing that too just now...I added half a gallon n it was then to the full line but the flashing alarm light stays on. Going to unplug for now.

#beardedmechanic Forbes thank you very much, I’ll check its magnetic and I hope it stops flashing
Hey
How abt if we unplugged the sensor??? Is it safe to do so ?? For moter
You can unplug to stop alarm but you will have a engine code light on. If its just a bad magnet in resviour or bad sensor your engine wont be harmed

I’m trying this lol
where did you tape the magnet ?? I can't take the dinging any more !
Tape or glue a magnet on the sensor prob solved
Good idea to try. Would you try to stick the magnet onto the rod that goes into the reservoir towards the upward top of the rod or to the bottom of the rod closest to the plug on the sensor?
Can this cause a derate
On most semi I worked on it causes engine shutdown(with yellow and red engine light) if coolant goes to low ,with no derate code or error
So my truck went into DERATE due to a coolant warning that shut the entire truck down, I replaced the coolant level sensor , but now the coolant light stays on while truck is idle, but once the truck starts to drive it goes away and comes right back once I stop even at a traffic light
