oil temp and water temp gauge

• 2023-09-15

Ordinary cars only have a water temperature gauge and water temperature warning light, while ordinary cars do not have an oil temperature gauge and water temperature warning light. The sign of the water temperature warning light is that there are two wavy lines below, with a thermometer inserted in the wavy line. Most cars use water-cooled engines, which rely on the continuous circulation of coolant to dissipate heat. There are two circulation paths for coolant in the engine, one is a large cycle and the other is a small cycle. When the engine is first started, the engine temperature is relatively low and the circulation of coolant is small. 

Therefore, the coolant will not dissipate heat through the radiator tank, which is conducive to rapid engine heating. When the engine reaches normal operating temperature, a large amount of coolant circulates. At this point, the coolant will dissipate heat through the radiator tank, keeping the engine temperature within the normal range. If the water temperature is too high, the water temperature warning light on the dashboard will light up. 

What is the car with the oil and water temperature gauges above the middle: a Buick. The meaning of a small wrench appearing in the middle of the car water temperature gauge and oil gauge is to remind the need of the vehicle: 1. Generally speaking, this type of maintenance refers to changing the oil and three filters. 2. Different vehicle models may have special maintenance and repair items at different mileage or time periods. When this small wrench appears, it is best to check the instructions for using, repairing, and maintaining the vehicle, Try to carry out maintenance projects according to usage requirements as much as possible.

The high oil temperature, rather than the high water temperature, is a problem with the lubrication system and is not closely related to the cooling system. This has no impact on whether the air conditioning can be turned on or not. Analyzing the problem from a principle perspective. The high temperature of engine oil is definitely related to friction because it serves as a lubrication function. However, if the friction is severe, the temperature of engine oil will naturally increase. Poor sealing of the piston rings can cause high-temperature and high-pressure gas to penetrate the crankcase, and the engine oil is inside the oil pan.
