I recently did the fluid/drain procedure twice I found on the forum this past Saturday. I managed to get 2 1/2 gallons back into the system after the final drain. Is there any reason why when I am driving down the road at about 64mph that the low coolant light should come on? When i got to where I was going I looked at the reservoir and it was actually about an inch above the full line.

I am totally confused

What could be causing the light to come on if the system is full or even over serviced a little.

 

OMG. Here's another one AGAIN!!! Ever thought about doing a search?? You might find the other thousand threads about this problem!

 

Check out https://www.rx8club.com/showthread.p...crets+revealed

Also, what coolant did you put in, brand and mixture??

 

Yeah, and there are plenty of threads around here explaining roll-over noise in the factory transmission but that didn't stop you from recently asking an easily-searched question about it, yourself. Nor the question about your noisy air pump.

 

lmao join date sept 10 and your saying this STFU

 

I didn't start a new thread now did I?? No, because I did a search.

 

No. You revived one from a couple years ago that had ZERO information in it.

Who really cares anymore about this "Search, NOOB!" nonsense anyway? It is fairly well-known around here that the search function is far less effective than even using Google to search the RX8Club. That is why I am no longer bothered by those who do not appear to have searched. Nobody needs to excuse anything when asking a question, either, because this forum has changed dramatically since the early days.

It is always the new guys who bust ***** about failing to search.........

 

I am using Prestone coolant and its 50/50. I noticed the light come on again today when I was driving like 30 mph to work. I will check that thread out again, I saw it the other day just didn't know if there were any other explanations than a new coolant bottle.

 

I am totally confused

You wouldn't be confused at all if you would have spent the same amount of time it took to write this post searching through identicle posts to this one.

And the list goes on. Take a second and use the search button before wasting everyones time.

 

Good luck. Mine used to do it occasionally on the track. Did not the last time around. I asked about coolant because I am trying to work out if the coolant might be foaming, but that would only be an issue if you were driving 30 in 2nd gear...

 

my light has come on one time that was on a track day. Ever since then it hasn't showed up again. I would say as long as you monitor the tank you will be fine.

 

The bottom line is............you can

1.) Take the bottle out and attempt to clean it, but seems to only last a period of time.
2.) Buy a new bottle.
3.) Unplug the sensor and monitor coolant level on your own(suggest when checking the oil which should be every week.)

This usually starts out happening at high RPM's and gradually gets worse until it's on all the time. Sorry that first thread linked was so long, but I was trying to understand why it happens.

 

There's one more option:

4.) Let it be. Enjoy the light show. Think of bizarre explanations if your passenger asks what it means. (E.g., "It's a Greek temple. The car wants us to stop and get a gyro.")
