The float in the bottle is stuck, you can take the bottle out and try swishing some hot soapy water in there, sometimes that will free up the float, or you can buy a new bottle, they're on amazon for cheap and easy to change. btw the float itself is not replaceable.
there are actually TWO parts to the sensor -
built into the tank is a donut shaped magnetic float -
the green thing in this pic -
SOMETIMES that float - or the center post that the float rides on - gets all crudded up - and sticks -
and SOMETIMES this CAN be cleaned using various soaps - solvents - cleaners - etc -
and shaking the crap out of it -
on other occasions - the sensor itself has failed -
this is the part that the blue harness plugs onto - in the pic -
it was ALWAYS reported that this sensor is NOT replaceable -
actually - the coolant level sensor IS replaceable -
remove the surge tank -
unplug the harness -
and simply pull the sensor straight down -
it is a tight - friction fit -
the replacement part is STANDARD FLS16 - $10.25 - including shipping -
I had the same experience with my 2001 Deville. It was the coolant level sensor that was bad. I bought one from Ebay for $10 or so--aftermarket. At first it still read check coolant level. Then it went out. Never came back. If you put a paper clip across the car's current sensor connections, and the Check Coolant Level message goes off, then you know it's the sensor.
Yes, and if you test it with a paper clip across the terminals, and the message vanishes, you know it's the sensor. My replacement wasn't a tight fit, but in time it apparently was "fused" and the lights went off.
The heat in my car only works when your going highway speeds (about 45 and above) when at idle or just cruising in town it blows almost freezing cold anyone know what can cause this? And this is with the ac turned off and heat cranked all the way to 90 degrees
So I have been sourcing out some parts for the car and wouldn't you know it OEM sport coil springs and dampeners no longer available. I cross reverenced the part # and came across these dampeners.
Question is if they will throw any suspension codes. Has anyone tried these yet? Also it seems to...
Hello everyone. I just took ownership of this 99 Deville Concours. Its been in the family since new and belonged to my grandmother, then my dad and now me. It is far from what cars im used too ( mostly Mercedes and BMW's ) but my dad gave it to me as gift. From what I can tell it will need some...
The daytime running lights go on, but when we pull the knob to turn on the headlights, they shut off. We have changed the bulbs, checked the fuses, replaced the relays, and bought a new switch and still have the same issue. It was suggested that it could be the turn signal switch that controls...
