My jeep has had a temperature problem since I purchased it. I picked it up as a surplus vehicle from Colorado auto sales in Denver and one of their listed problems was overheating. Here is the life of the problem so far.
Purchased, drove to a car wash and pressure washed the radiator. Lots of Pea gravel came out. It still overheated while sitting in traffic but was ok while moving.
I got home and removed the radiator, it appeared as though there was a birds nest between the radiator and the condenser, and the black rubber had fallen down blocking the airflow. so I cleaned it out.
The jeep still overheated at idle and during low speeds, so I changed the fan clutch.
The jeep still overheated at idle and during low speeds so I flushed the radiator and replaced the thermostat with a 180* unit.
THe jeep still overheated at idle and during low speeds so I replaced the original electric fan
The jeep still overheated and I developed a heater core leak so I replaced it
The jeep still overheated at idle and during low speeds so I removed the mechanical fan, replaced the radiator with CSF 3 core, replaced the thermostat and radiator cap.
The jeep still overheated but only at slow speeds while running higher RPM's
The fan bracket broke and the e-fan rubbed a hole in the radiator.
I replaced the radiator with another 3 core CSF unit. and replaced the fan.
The jeep still overheated at idle and low speeds. So I moved the radiator forward, installed a Ford Taurus fan, and 10" e-fan. and replaced the thermostat.
The jeep still overheated at idle and low speeds, I discovered a drip from the water pump and when inspected saw that the flange face was pitted and would not seal, I installed a new water pump.
The jeep still overheated at idle and low speeds, and run cold in very cold weather. I removed the thermostat and the damn thing had a set of catches on it that never allowed it to close once it had fullly opened. I replaced the thermostat and re-filled the system
This is where I am today.
The jeep still overheats at idle and low speeds unless I use the High-speed of my Taurus fan, and my alternator can't keep up with the draw at idle. I have tried the super cool coolant, regular coolant, pure water.
It's not terrible, I can keep toggling the fan from high to low to keep it cool, but it's only 65* outside I shouldn't have to do this. There is no part of the cooling system except the overflow bottle that hasn't been replaced, and it's an open system. I hate to admit it, but I have no idea what is wrong. It isn't eating coolant, or putting oil/soot in the coolant, nor is it putting water into the exhaust. It isn't running poorly, it just keeps going over the 210* mark with 180* thermostats in it. The 180* thermostat is for the Jet Chip. Yes it still overheats without the chip.
