- 2003 Explorer 4.0L
Hello all, My explorer is a 2003 EB 4.0L with the 3.55 gears. It does have a class 3 hitch and trailer brakes ect. I bought a new travel trailer that’s around 3900 Lbs. I’m using ODBII to monitor temps and I am concerned about how hot the engine and trans are getting.
I monitored temps without the trailer first then with the trailer. Without the trailer the trans temp was running 169F - 176F and the engine temp was around 200F - 220F. While towing the trailer on the long high speed stretches the engine temp was fine but the trans temp climbed as high as 223F. Then for the stop and go portion of the trip the trans temp stayed normal but the engine temp would shoot up every time I accelerated from a red light. It would then cool back down while moving and while stopped then would go back up when I had to accelerate again. The engine temp would get up to around 240. The temp gauge would read just a hair over the 3/4 mark.
On a side note I am in FL and it was very hot, Around 94 degrees. Are there things I can do to cool the car down or am I stuck? Sorry for the long post but I can’t seem to find definitive info on what a safe temp is. ( I did check coolant level and it is full )
