First of all, sorry for the long post.
I have been reading about covering up some of the grill to improve aerodynamics. Since I have pretty consistent mileage numbers, I thought I would try this to see what effect it will have on my MPG. But I have a question, what temperature should I try to keep under on my radiator? From my scangage, I know my Neon stays pretty steady at 192F. But what would be too high? The coolant gauge on the IP is nothing more than an idiot light since it doesn't move when the water temp runs from 180-210. The reason I ask is that I did my first mod and think I covered too much. The temperature got as high as 210 (during some running around town). I came back home and opened up some more grill and went for another test run. Now it seems to be staying under 205 (193-204). This is on a relatively cool day - 70F.
I must say, my regular commute (50 miles one way) is 90% highway (60-70 MPH), so I am thinking this shouldn't be an issue at that speed. But on the weekends running around town I don't want to have to worry about it getting too hot. Thanks for the read
