I have a 1999 in Arizona. I have recently flushed the radiator and replaced the coolant. I have recently upgraded to 4:10s & 35inch tires with a 4.0 and automatic. Some questions on temp and thermostat.
Right now it runs around 190 running to the store and such. Out on the highway running 60 (2400 rpm), it will heat up to 220 - 230 in 5 to 10 minutes. trail running at low speeds, it runs 210+. I am going to check and see if it even has a thermostat in it. But regardless I am going to put in a new one. Questions?
What temp thermostat for Az?
What is a comfortable highway RPM for running on the interstate to trails in Az heat and a good condition 4.0 motor, but 130,000 miles.
I still have the stock speedometer gear in and use a gps. At 2400/2500 I am doing 60/61 mph. But my speedometer says almost 70. It seems 70 would have been plenty fast to cruise when it was new. At 2400, that is what 90% of the drive train is running, 70 mph. It also seems like I am pushing it at that speed. But I just realized it has been in the heat with the top off and the wind blasts and such may make the “pushing it” feeling exaggerated.
I also have a winch on front so some airflow is shielded.
Thoughts on thermostat rating and comfortable interstate RPM. Also, will a newer radiator help?
