Yes my TJ is a 4 cyl, I will just have to keep an eye on the gauge this week and make sure it
doesn't go higher then 210 degrees.

4.0's run right at 210. I don't know what the 4 cylinders run at though.

[QUOTE="ledlis"]So my 1997 TJ was overheating after 15 mins of
Idle, so I decided to change the thermostat. After
taking off the housing there was no thermostat inside. I couldn't believe it. I've been driving around for the last 2 months with no thermostat. Roughly 2k miles.
After putting a new thermostat in the temperature gauge is @ 210 Degrees. What is the normal temp range for your jeep?

The only problem with running without a thermostat is that you may be running with your coolant temperature too low as the role of the thermostat is to maintain a constant higher set temperature. No thermostat means variable lower temperatures dependent upon external ambient temperatures.

There is one other issue when running with no t-stat. If you look at a thermostat you'll notice that the valve is inside a ring. When open the size of the hole is smaller than the size of the housing. This difference in size creates some "back pressure" in the block. This back pressure makes the coolant circulate better in the block, especially in the back of the block. Running without a t-stat can actually cause coolant to seem like it "boils over" because of the uneven circulation and cooling between the front and rear of the block. Although not as noticeable in smaller engines it can still happen.

It seems to be running @ a steady 210 Degrees.

I was stuck in traffic the other day and it started
too overheat again. The problem is the fan is so
far away from the radiator, it's a 4cyl TJ. When Im driving its fine, but when I stop n go in traffic,
it rises steadily.

I'm thinking about putting a fan on a switch to
turn it on and off when I end up in a traffic Jam.

Has anyone else ran into this problem?
