Hi. how are you fellow 8 friends! i have a question.. Once in a while my coolant warning light would come on and off... but when i look at my temp gauge seems to be fine.. its that light keep going on and off everrytime i use my paddle shifter or going 70 mph and over.. How do i solve this kind of problem? thanks!

 

the sensor in the tank is bad.

either replace the entire tank or unplug it and check regularly.

 

how much is it if i take it to the dealership? any idea?

 

is this something i should freak out about?? i dont want my 8 to overheat or something

 

Its a faulty censor. It hapeneds to all the 04s I just ignore it now but check my water level every fill up.

 

The stealership is going to charge you about 200+ to change it. I say just live with it like the rest of us do. Just check it every fill up and you'll be good.

 

My car used to do that, but only when pulling ahead around the top part of 4th gear- strange

 

This was happening to me earlier in the summer. I put a bottle of Water Wetter in the tank and since have been vigilant with checking the level. It has not come back since then, and I used to get the light everytime I was above 4500rpms for more than 10 seconds

 

how often i should check my coolant? everytime i get an oil change?

 

once a week

 

Check it once a week or every time you check your oil. But something tells me you aren't doing that very regularly either are you?

You can actually take the tank out itself and flush it out real good and you will be okay. All the experiments I did indicate that it's the crud in the bottom of the tank that keeps the magnetic float from doing it job.

If you really wanna read all about it, go here..............but know that I went way far with this thread.

the light used to make me nervous, but i check the level all the time and it's been fine. now i just ignore it. good info in that thread!

 

well so im going to take it to dealership and let them flush it for me.. i hope they wont charge me alot!!

 

haha my light used to go on an off back in the day, now its just permenantly on along with cel and sometimes airbag light wich i think is due to my rediculous bass

 

I disconnected the coolant level switch and the light indicator does not come on any more. Thanks Guys!!!

Question: Does that switch run in series with another switch or sensor? Will disconnecting the coolant sensor prevent any other sensor related to this light indication on the dash? Is the red light just below the Oil pressure gauge only for indication of the coolant level or is that light for other sensors?

 

hey good to see everybody from the coolant false alarm alumni club again

 

mine does it too from time to time, just keep checking the temp and the coolent level.

 

ok i just went to the dealership today and i GOT omfgbbqrofl owned. I had an oil change and of course it was around 49 bucks. and then i asked to check my coolant cuz i told em my situation and guess what! they want to charge me 300 bucks or something to fix it. i was like aight well **** it. just check my coolant level.. and if you can just fill it up or something if it needs to. and then they charged me 47 bucks for that. so my total came up to 80 bucks. still.. i felt neglected..

 

This happened to me in the summer.... only when I was at 4K+ for a while.

I just added coolant...
