How to replace coolant temperature sensor?

Topic, there are 2 I would like instructions on both if at all possible I want to know how hard this can be thx

I think you just unscrew it for the one that is on top of the thermostat housing and theres another one on the other end and that one I have no clue maybe also unscrew?

They both unscrew. Be sure to use thread sealer on the new ones when reinstalling them.

there may be one or two, one for the gauge and one for a fan switch or ecu sensor, the gauge one is often a 1 wire one, others are usually 2 or 3 wires

There are 2 one is on top of the thermostat housing which is the sensor and the second one the side of the thermostat housing. I'm replacing the sender which is the on the side with 2 wires. I'm just concerned cuz I can't seem to figure it out. I will try and see what I can come up with I know they unscrew there's just some other stuff looks like I have to take the intake out to have a better angle.
