i have a 90 gxl n/a. i was driving down the road and my add coolant light came on. i pulled over at my first chance and checked the fluid and it was full. then went driving again and it didnt do anything. was on my way back home and it happened again. got home checked the fluid and it was full once again. does anyone have an idea what could be going on cause i checked the wires to it and their fine. the connection is fine and the coolant is full. im lost please help

 

rxs are typical for electrical problems i believe, if theres nothing wrong i wouldnt sweat it, unless that little light annoys you that much maybe its the sensor?

 

have you filled the coolant recently? you may have an air bubble in there. start it cold w/ the rad cap off and let it warm up. once the thermostat opens, if there is an air pocket, you should see the water get sucked up and outta the radiator. then fill it up.

 

i tried that and their was no problem. so im guessing its the sensor. the only problem is mazdatrix is the only place i have found that seels it. thanks for the help though

 

have you checked the classifieds on here?

 

Your warning/idiot light panel might be facked. Might have to resolder some of the points in it.

 

no i havent tried the classifieds yet but i will. and with the cluster i have resoldered it once but maybe i missed that. the crazy thing is it doesnt stay on all the time. it does it for a lil bit then quits the starts back up. and it only does it when the car is heated up. im gonna try both of that though.

 

well i got a new sensor and resolder the idiot lights but it still is going off. im lost on what it could be. any ideas

 

you could always get a new panel

 

If the wire leading to the sender is open somewhere, the buzzer will sound.

if you have a fray anywhere in your lines then it will come on every now and again (like mine). Also make sure there are no bubbles (as previoiusly stated). Id say drop your coolant and refill it correctly.
