hey guys, my coolant sensor is going off whenever i start up the engine and it is completely cold. I'm positive it is a bad sensor that is just not reacting well to the winter (it started about a month or so ago as the temperature really started to drop around here). I had it in at the dealer a couple weeks back (for an oil change) and they didn't find anything right off the bat (as the engine was already warmed up as I obviously just drove it to get there) .I don't have the cash at the moment to take it in to get it replaced by them.

Is this something that I can replace on my own? (i'm really handy with that sort of thing.) If so, anyone know where I can pick one up, and how to replace it?


Thanks!

 

they come on blue when it is cold untill it gets warm if it comes on red you are geting hot or low on colant

 

well, it's lighting up red, when i initially turn it on, then goes away after a minute or two.

it's definitely not overheating as the engine is dead cold when it does this. and the coolant level is fine, when i was in for an oil change like 3-4 weeks ago, they topped it up, and it made no difference.

 

might be the level sensor in the bottle
