Just make sure you get the air out of the blinker when you fill it. Almost forgot. Put it in park and shut engine off when filling or checking blinker fluid level.
As long as you are going to be working on your truck...be sure to switch to winter air in your tires and rotate your air filter.
I spammed the entire school where I taught auto and got some interesting responses. Laughter from those who knew and "I need to learn more about taking care of my vehicle". One person asked where they could get winter air and I said after Dec 21 anywhere.
