hi guys thanks for the advice,the temp gauge in my dash has all of a sudden been either going all the way up or all the way down.not over heating car seems fine.is this something that is worth fixing or should i live with it?
thanks
mike

 

sounds like you are low on coolant

 

no the coolant is new and full

 

go with a mechnical guage,, i did and i couldnt be happier

 

well, have you verified if the temperature is actually changing?

 

It sounded like you said it overheated. If it did, and you filled it up, there might be air pockets in there, causing the erratic temp guage. You may have to burp the system by letting it run without the rad cap on until the t-stat opens
