Volvo XC 90 2004 temperature gauge goes up immediately at the half mark after only 4 blocks or 5 minutes of driving.

SOURCE: temperature gauge reads high

i think there is 2 sensors or your thermostat might be stuck. you can remove the stat and see what happens if it runs cool then replace it

SOURCE: Engine Temperature Guage on Dashboard indicates overheating

Hi and welcome to FixYa,

Offhand, your described condition indicates a sticking thermostat, that is there is considerable delay before the thermostat opens. It is also possible that there is some restriction wherein the thermostat is not opening completely when the triggering temperature has been reached. As a test and to confirm, you could try temporarily removing the thermostat and operate the engine without one; observe temperature. The side effect of this test is that it would take some time to warm-up the engine, but operationally should not cause anything untoward. Of course, care has to be exercised that the gasket would still be intact.

Good luck and thank you for using FixYa.

have you checked to make sure its not leaking into your oil. most heater core leaks will be on the front floor of the passenger side of the car.

SOURCE: 2002 malibu runs hot.

Sounds like you have a faulty head gasket or maybe a cracked head.This can cause overheating and the check engine light to come on.The code for the o2 sensor is probably caused by coolant getting into the exhaust system and coating the sensor.The coolant fan may work but it cannot remove enough heat from the rad to make the engine cool off.Try some engine coolant stop leak to see if it will help.This maybe only a temperary fix.Let me know if you need more.MOE

My civic did the same thing, twice, no over heating on the gauge, but the head gasket on both engines broke in the same place, #1 cyl. there is a TSB on the head gaskets, I replaced it with a felpro head gasket, had the head checked for cracks and decked, runs smooth and my wife gets 40 MPG
Pull the #1 spark plug and check for coolant on the plug. make sure you flush the cooling system.
