Question about Buick Enclave
My 2012 Enclave engine temp is consistently 210 degrees F. That's almost a boil. Is this the common operating temp for this engine ?? Seems too high and damaging, Only 1000 miles on vehicle...

Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.

it sounds like a possible head gasket problem,you can get the fluctuation from combustion gases getting pumped into your cooling system and creating gas pockets,i would suggest taking it to a shop and have them do a block test to look for combustion in the cooling system to confirm the problem,that way you will know for sure,if it comes up negative they can also perform a flow test to make sure there is no restriction in the cooling system such as a plugged radiator or a bad thermostat,hope this sheds a little light on it

Testimonial: "I bet you've hit on the problem ! Car has been "using " antifreeze for a couple years now, with no leaking anywhere. Lost through the head gasket ?"
SOURCE: WHERE IS THE SENSOR LOCATED?
This is a known problem. The temp sensors go bad every so often. VW recognized this a few years back, updated the sensor and accordingly changed the colour from brown to green. oops.... They still go bad. The sensor is on the drivers side of the engine, on the back of the head in what looks like the thermostat housing. If you have a man trans there's a set of glow plugs commin out of it. This is the only temp sensor on the TDI. There's a plastic horseshoe clip (the dealer should have offer you one when you bought the sensor) you have to pop out, then wiggle the sensor until it comes out. MAKE SURE THE OLD O-RING COMES OUT, this will make instaling the new sensor much easier and will prevent your all your coolant from leaking out.... Yah, I seen it done, not good. Worst part is you can't see what you are dooing so good but its fairly simple. Good luck and happy motoring
