OK guys, this is kinda weird...

For the past week I have been getting a coolant light on random mornings when I first start up the 8. I got one on Monday(last week) Thursday, and this morning. It comes on right when I turn on the car but the SECOND I start moving it goes off. I checked it and its not low, oil is good. When I free rev in the morning when it is on it stays on, but the second I move it goes off.

Any Ideas?

ps: I DO have the coolant mod from mazsport, think that could be part of the issue?

 

there is a thread about this very issue somewhere here

 

Have you considered adding a little coolant?

Ok guys, I did a quick search. Found nothing about my exact situation Brettus...

If anyone has any info on these please feel free to part your knowledge. I don't understand why it would be there then right when i move go away..

 

I'm going to mention something even though I don't know much about car or engine mechanics. Over the past 2 months, my coolant light has come on 3 times, the first 2 times for a split second and the 3rd time for about 2 seconds. All 3 times I was cruising on fwy stretches that were a slight incline. Two different technicians at two different mazda dealerships told me sometimes there can be a bubble in the coolant lines. Once the bubble gets past, the light goes off. Who knows what is behind your observation but I just offer a possible factor.

 

phil has it a bit right..

if you car is under warranty. have them take care of it..

the sensor goes bad in the 04s... i am getting the light about 3 times a month right now.. no rhyme or reason.. it i just comes on for a min.. then gone..
