I have a 2006 Cadillac DTS my temperature gauge goes up and down but the car never overheats. When the needle is in the red the car putters but when the needle fall it rides smooth again


Actually, by your very description of the symptoms the car IS overheating. The temperature gauge should NEVER be "in the red" as this is too hot for the engine. The "puttering" you describe is the engine laboring to stay running in the overheated condition. This is shortening engine life dramatically. It sounds like you may have a thermostat that is not opening completely, or a cooling fan that is not operating correctly. If a fan problem it could be either the fan motor itself or the coolant temperature sensor that turns the fan on. It is imperative that you get this looked at IMMEDIATELY. The engine on your Cadillac has aluminum heads and they are easily warped or cracked by heat. A third problem you could have is a low coolant level. Never trust the sensors in the overflow bottles. If the coolant in the reservoir gets depleted, then the system develops air pockets which cause overheating and erratic gauge operation. If this is your problem, topping off the reservoir and purging the air in the system should clear things up. Be advised, however, you should also be on the lookout for system leaks if this occurs.

Mini Cooper temperature gauge goes to red zone when idle


check coolant level could be too low allowing air in the cooling system causing air pocket in engine around the engine coolant sensor.coolant sensor needs to be in hot coolant so it will cause the cooling fan to come on at a set temperature.make sure coolant correct level and the coolant level in the cooling overflow jug should be at full cold mark.the cooling overflow jug should never be empty,if you see empty cooling overflow jug air got in the cooling system so make sure when engine cold every time raise hood make sure cooling overflow jug coolant level at full cold mark.if jug stay empty you have cooling leak.so replace radiator cap,if coolant level all good,i would replace the engine coolant temperature and thermostat.when your car come to a long stop or driving along long line of slow moving traffic the engine coolant blower motor should running if not have vechicle code scan for faulty coolant fan motor control module.or ecm problems.

2000 Chevy Impala - Temperature gauge goes into the red quickly. I had cooling fan assembly replaced 2 months ago because car temperature gauge used to go into the red and sometimes stall.


yea they are right right undo the hoses from the coolant container to to the radiator and the hose from the radiator to the engine and let it all drain out then put it back on and put some new radiator fluid in the radiator until ist full and then put some more in the container for extra make sure to put both hoses back on

Honda 98 CRV temperature gauge goes way up after an hour on hwy


You will need to change your thermostat as it is stuck and is not responding correctly to temperature changes. Have your mechanic change the thermo, do a flush of the system and all should be good again.

When i drive the car the temperature is ok. When I switch off the engine the temperature increases to 3/4 of the gauge


This condition is not unusual.It is called heat soaking. When you turn off the engine or are not moving there is no air crossing the radiator. There is also no water circulation and the fans are not running. It is a normal condition. Good Luck
