welcome to the board... btw you posted in the wrong section... but what your problem is air in the cooling system. usually you'll have to replace the engine coolant temperature sensor. but only do so after you have found out why theres air in the coolant system... fix the source of the problem and then bleed the coolant system to get rid of the air and change the sensor. dont just change the sensor without bleeding the system. I went through 3 sensors already.
