This is my dad's car and he was driving along the other day when the coolant warning light blinked on and off again...he drove on and it didn't come back. When he next went to use the car the coolant warning light was on all the time and the temperature guage was blinking with all of the little digital arrows being present. I went to take a look at his car and the coolant level was fine there's no leaks and driving it myself there's no sign of overheating plus the fans kick in when they're needed.
It's exactly the same as the gauge in this thread
I've been looking for a solution to this online and can't find anyone with a solution to the issue...few people asking but no one reporting a fix. There doesn't appear to be anything wrong so is is just some sort of glitch? Can I reset the light or do you think it's best to replace the coolant temperature sensor which is all I can think to be causing the problem? Unless someone knows something else and it's actually worse
Any help and input at all would be very useful and thanks in advance!
