First off you have a bad cooling fan and second you either have a bad sensor or relay.......
Probably your thermostat has stopped working. I've had this problem several times.
BAd radiator cap, low coolant or (leaking), Bad thermostat, cooling fans not turning on.
Turn the AC on and the electric fan on the radiator should run.
also it keeps turning off ,you put water in the reserve and several minutes later it's gone even when the radiator is full. It also makes this High pitched sound(like when a belt is going out that kind of sound),
if you're facing the front of vehicle, it is on the lower Left hand side of the radiator. If you're underneath the car facing the radiator, it will be on the lower right hand side of the radiator. It has a plastic turning screw.
When standing facing the Suburban, the radiator drain plug is on the lower right-hand side of the radiator. Drain the radiator coolant into a bucket by turning the drain plug three-quarters of a turn to loosen.
The petcock is located on the passenger engine side of the radiator. It doesn't extend outward from the radiator; it's actually inset to it. Turning it counter clockwise opens it.
Dead battery if it is having trouble turning over or the starter motor is going out. Check the battery cables and ground straps at both ends for corossion
You have a leaking transmission cooler, usually part of the radiator. The transmission fluid is mixing with the antifreeze turning it pink.
Lefty loosey, righty tighty.
Does this squek vary with speed? When stopped and turning right does it squeak? More info is needed
No, this will not damage or cause wear on the struts in any way.
