What Causes a Buick to Display Engine Overheating?

[StSilas]

If the vehicle's water temperature gauge shows below 50 and the dashboard indicates engine overheating, this fault phenomenon is basically caused by a malfunction of the engine water temperature sensor or its circuit. It is recommended to visit a repair shop or 4S store to inspect the water temperature sensor and its circuit. The benefits of engine internal cleaners are as follows: 1. They can efficiently remove carbon deposits, gum, and other harmful substances inside the engine. 2. They can prevent combination, clear the oil film and sludge formed by old engine oil, thereby avoiding a reduction in the performance of new oil. 3. They can enhance engine efficiency, thereby reducing noise and also decreasing fuel and oil consumption. 4. They can neutralize long-term harmful acidic substances generated inside the engine. 5. They can clean the crankcase PVC valve and the hydraulic lifters and valve lifters. 6. They can purify the engine's lubrication system, lower engine temperature, and improve oil fluidity.
