Where is the Buick Regal water temperature gauge sensor located?
2 Answers
The water temperature gauge sensor of the Regal is located directly above the junction of the engine and transmission, on the side of the cylinder head. Damage to the water temperature gauge sensor can cause the gauge to remain at the same level, leading to incorrect judgments by the driver. A faulty water temperature sensor should be replaced promptly, as it can affect driving safety. Solutions for excessively high water temperature are as follows: 1. Insufficient coolant in the cooling system causing engine overheating: Park the car and add coolant after the engine cools down; 2. Loose or broken water pump or fan belt causing engine overheating: Visit a repair shop to replace the relevant parts; 3. Radiator guard mesh or radiator core ventilation duct blocked by debris: Resulting in poor heat dissipation and engine overheating. Replace the radiator guard or clean the debris; 4. Insufficient engine oil or substandard oil quality: Causing engine overheating. Simply replace with high-quality oil.
As a DIY car enthusiast who frequently tinkers under the hood, the Buick Regal's coolant temperature sensor is located in the upper engine area—specifically near the cylinder head or water pump. You'll need to pop the hood and search carefully—it's a small metallic component with an attached wire, quite visibly positioned. I recall fixing one on a friend's 2014 Regal where it was secured beneath the intake manifold, easily detectable by touch. If your temperature gauge acts up—showing erratic readings or failing to rise—it's likely due to sensor contamination or poor contact. Cleaning the connector or replacing the unit usually solves it. Always ensure the engine is cool before working (safety first!), and keep a multimeter handy to check circuits for reliability.
