        First thought would be ensure the cooling system has been properly bleed and check for any obstructions of air flow.

            Possibly.
            Or a faulty sending unit, or wiring.
            Best to check the actual coolant temperature to see if the gauge is accurate.

              The sending unit is new could it also be a leak somewhere?

                The sending unit is new
                New does not always mean properly functioning.
                Which is why I suggest you confirm the coolant temp.

                could it also be a leak somewhere?
                Are you seeing a loss of coolant???

                    Thats where the needle is all the time after it warms up ofcourse .is it normal for the gauge to stay like this after i turn the engine off?

                      Engine off, key in hand..?
                      If that’s normal, it is the first time I’ve seen gauges remain active with out the key in the accessory or on position.

                      It is possible you may have an issue with your cluster.

                        Yes thats the reading on the cluster without the key in the ignition if i put the key in they will drop and will go back up as the engine warms up
