So I got my radiator flushed at EZ Lube about three weeks ago, that day I drove about for three or four hours straight in about 80-100 degree heat. About four hours after leaving EZ Lube my radiator light came back on! So, I went in the next morning and they said that they assured me nothing was wrong with my radiator and checked it. For three weeks it's been coming on and off when I drive so I had my neighbor who's a mechanic check it out. He used his computer sensor thing( yikes! don't know the technical name...) to check out what was the source and it came up nothing with the radiator.... The only problem he could come up with were the sensors but he's not very fermiliar at all with rotary engines (works at mercedes...) and to take it in to get checked to be safe. Aybody else got any ideas??? Thanks!

 

search ... the coolant light on our 8s fail alot check the level if its fine then its the light if you have doubt add some and if the light is still on either go get a whole new coolant reservoir (whole unit sensor is embedded) or unplug it

 

people these days really cant find answers on their own do they ?

 

nop not at all ... so many useless threads lol the only reason i actually reply is so that in case some people actually search for sth they will find the reply

 

sounds like you might be low on coolant.
try adding some 50/50 mix to the overflow tank.

there is a DIY by on coolant changes, check it out.
if you do an advanced search, type in coolant change, and then have it search 'titles only'

Ooooooooooooooooooohhh! That's a low coolant light? I feel so stupid that all this time I've been thinking that it was a little picture of a birdcage, or a Rolls Royce grille.

 

Your owner's manual explains what all the lights indicate

 

the owners manual is unheard of in these parts
