Got a 2005 900 switchback. I check engine light is blinking in 2 set increments. I believe this mean low coolant but not sure. I added coolant because it was a little low and ran it on the track stand for for about 4 minutes because I also read that it needs to run for 3 minutes at above 3000 rpms. Didnt seem to help. Any thoughts or ideas? Thanks in advance
