Above vehicle with overheating issue, temp gauge was reading high, when warning to investigate , no water leaks, coolant at normal level, thermostat possibly, your thoughts thanks.

stuck thermostat or impeller on water-pump no longer moves are the first 2 things come to mind.

Was the air conditioning running at the time? Does the radiator fan appear to be working?

If it is a failed radiator fan, the car will run at normal temperature at open road speed's, and will only overheat at low speeds. Also Cranking the heater to the max will make some difference (perhaps not enough to avoid cooking the engine).
Would be fairly easy to diagnose a failed fan on the driveway. Just idle and watch the temp gauge. If the temp gauge is above normal and the fan dosn't kick in it's faulty. Shut everything down before the engine gets cooked.

If its the one I'm thinking of the fan controllers were prone to failure. It's a box mounted to the fan mounting frame, if you run the engine and switch on the A/C and the fan doesn't come on, and you firmly tap the box with say a screwdriver handle and it does come on, or pulses and stops again, you need another controller. Radiator fans dont necessarily just turn on and off when tripped by a radiator switch any more, it will be run at varying speeds determined by the engine controller based on what the operating demands and of course the temperature of the engine are at the time. It will always be running when the A/C is on as condenser airflow is critical to its function at all times.

Try checking to see if water looks like it is flowing through the radiator once it warms up a little. Just run it without the cap on, it would be safer to take the cap off when it is cold.

I've got a CE lancer wagon but I don't think the OBD2 port will work with one of those gizmos.

temperature is covered under obd2 emission room. it will say -400 or something if the sensor faild. As where in factory room it will say 56 as it uses a substituted value. obd2 emission is not allowed to substitute values . by law.

Would everyone have been so helpful if the poster was a woman? I remember a recent overheating thread where many people said to not touch the car and get a mechanic to fix it.

Never thought about the posters gender. I'm sure most others didn't either. No one said they should try and fix it, just ideas as to what might be the cause.

No they said their husband was away, thus revealing that she was a woman.

Who said it had to be a woman with a husband?
I’m not sure if you are really naive or a troll.

It was a woman and yes people were very helpful and gave good advice to a person who appeared to know very little about cars.!

Well of course it could be a same sex couple, but the majority of married people are not the same sex, and if it was a same sex couple, I doubt that they would say "my husband" anyway.
