temp guage pegs out to hot before car starts V70-XC70

2001 V70 non turbo/ yesterday my high engine temp message came up on the dash after car only ran 5 minutes.I checked the obvious coolant level oil etc After the car cooled down a few hours I turned the ignition to accessory power with out starting and the temp gauge immediately went to hot pegging out without the car running. Today I replaced the temp sensor and I still have the same issue I looked for a cut wire harness but found no chaffed or cut wires I"m puzzled on this one.I hope Klauss can help me"smile"

Do me a favor, check the temperature on the gauge before you cold start the engine. When the needle starts going up, raise the hood and feel the upper radiator hose for warmth.

Replacing the ECT sensor was not called for, the old one was probably working nicely. What I asked you to do was remove the thermostat and put the upper hose back on. Running without a thermostat ensures coolant flow all the time and will take longer for the engine to 'warm up'.

Once the ECT sensor gets hot, the engine cooling fan should come on and stay on. Also check the cabin heat, it should also be hot.

After creating a hot spot in the engine, it will take more than a couple of hours to cool off.
