Engine temperature
Hello I own a 02 3.8L and today I noticed that when I was on the highway going 65mph my car was running a lil hot. Ive noticed over the years with past cars that my past engines have cooled off on the highway rather then heat up with the wind blowing against it.. Now why would my engine be hotter on the highway and cooler (below normal) on the streets?

If the thermostat was faulty wouldn't it throw a code?

The 3800 engine likes to run around 210° which should be the middle of your gauge, this is normal. If you have been running lower than that then you have been too low and actually losing economy and performance.
If your temps where higher than the 210 mark then check what other's have suggested. Also make sure you are not leaking coolant from the heater hose manifold where it goes into the intake and waterpump.

Its suppose to be at least 210? How come mine doesn't? Fluid is topped off at radiator cap. Do I add some also to the overflow jug?
