I have a Ram v6, 08. Used to run 200 deg all the time, rain

Customer Question

I have a Ram v6, 08. Used to run 200 deg all the time, rain or shine, summer or winter. Now it runs 206 to 211. It started overheating on the way back to CA from TX. I replaced t-stat, water pump, fan clutch, temp sensor. Temp sensor made the most difference. Also, gas mileage dropped a lot. No codes standing on OBD. What am I missing?

thats not overheting...is it pushing coolant out of the resevoir?

Customer: replied 4 months ago.
Negative, then why would temp change and why would the mpg drop at the same time?

when it overheated how hot did it get?

Expert:  xsvector replied 4 months ago.

i need to step away from the computer for 20 let me know how hot it got when it overheated

Customer: replied 4 months ago.
initially, it went to 213 climbing the grade on I-10 in El Paso. After that, it would vary from 195 to 213. After replacing aforementioned parts, all OEM equivalent or premium parts from Rock Auto, it did the same thing until I changed the temp sensor after which it would stay in the 206 to 211 range. Temp sensor was last thing to be changed, other parts were changed 1 at a time. To me, something is wrong, the ECU sees that in the temp reading and adjust the A/F ratio up to keep it from pinging or knocking thus dropping mpg.

Going to Bible study in 5 minutes, back in 2-1/2 hrs. Please leave final pointers. No codes on OBD, also, it idles smoother, another indication to me that the A/F ratio is up.
