Be careful you choose the correct sensor: There are two water temp sensors in this same area. One is for the car computer to determine correct running parameters. The other one is exclusively for the dash temp gauge.

The one for the gauge should have only one wire attached to it (Red/White-stripe)
The other is for the car computer, has 2 wires (Light-Green/Red Stripe, and Grey/Red Stripe)

The sending unit with the two wires attached controls the fans, which ultimately cools the engine.

To gain access, you'll need to remove the intake snorkel & possibly the throttle body. If your fans are cycling on/off during extended idle, then the 2-wire sensor is doing its job and the 1-wire sensor is not sending the correct signal to the dash gauge. Replace the 1-wire sensor.

On the other hand, if your fans are not cycling and the coolant starts to bubble and/or steam is escaping from the pressure relief on the radiator cap, stop engine immediately, let it cool off for an hour or so. Replace 2-wire sensor.
