Hi Scotty,  My water temp gauge is showing two tick marks to the left of 210 degrees constant. After doing the math it is an average of 182. Just had a new water pump put on along with new tensioner and pulley assembly. I have read that the gauge should be reading at 210 degrees. I have noticed decrease fuel economy like 13 mpg in the city. Is this something I should look into. What is the correct water temp reading? On my Chevy trailblazer Thanks!
