So my coolant sensor was flashing at me and becoming very annoying. I went to the auto parts store and they told me that it would be 50+ dollars for a new one. Well i eneded up buying one and installing it. A few days after that i found out that by cleaning it would sometimes make it work so i did just that. yes it work for HALF AN HOUR! after i took it back the new one. so now i have a coolant sensor sitting in my car waiting to be changed. the car is just to hot to do it! so that is my next project.
