How come my Nissan keeps getting hot?

My 2008 Nissan Altima is overheating; why?
The heater is a “heat exchanger” like the radiator on your car. If the car is running hot and you blow air over the heater “core” in the passenger area, you essentially boost the cooling system’s capacity, which lowers the temperature of the engine coolant that is circulated. The recommended approach is to avoid driving a car that is actively overheating until the problem has been fixed because overheating a car engine can result in significant, expensive, and difficult to repair damage. The heater will function as a temporary fix if you can maintain the engine temperature within the normal range. However, if the car is actually overheating, you face a significant chance of inflicting damage of many different kinds.
The most frequent causes of overheating include low coolant levels (including those brought on by leaks), malfunctioning thermostats, blocked radiators, leaky radiator pressure caps, collapsed hoses, inoperative cooling fans, and defective water pumps or drive belts. Overheating can also result from specific engine issues, such as a leaking head gasket or poor engine performance.

How can I check the thermostat on my car without taking it out?
The radiator pipe should be warm any time a car is overheating. The radiator hose won’t be hot, even while the engine is overheating, if your thermostat is stuck closed. Therefore, it is necessary to check the radiator hose first.
Place the car on a flat, firm surface. Depending on your transmission, engage the parking or neutral brakes. Start the car, then let it idle until the temperature needle on the display begins to inch closer to the North Pole.
Hold the upper radiator pipe with a towel you can get. If it’s warm, the thermostat may be jammed open, preventing the engine from reaching its maximum working temperature before coolant is injected.
It’s acceptable to believe that you didn’t wait for the engine to warm up to operating temperature before examining the radiator hose. Consequently, you can let the engine run for a little while longer before examining the hose once more. But if it’s still warm, your thermostat is jammed open and needs to be replaced.
Please be aware that thermostats typically open at 185 degrees Fahrenheit. Therefore, until the coolant reaches this temperature, a healthy thermostat should be kept closed. Additionally, the coolant must to be quite hot—185 degrees Fahrenheit.
Although a stuck closed thermostat is uncommon, it is simple to spot because the car will begin to overheat.
Cut the engine off. Hold the upper radiator hose in place with a towel or rag. At this stage, the radiator pipe ought to be extremely warm. However, if the hose is cool, your thermostat is jammed closed and needs to be replaced.
Remember that an overheating engine is a typical sign of a stuck closed thermostat. The thermostat won’t let coolant circulation to the engine and radiator if it is stuck in the closed position. Therefore, avoid letting the radiator get too hot.
If the thermostat turns out to be defective, your only replacement choice is a new thermostat.
How do you determine when to replace your thermostat?
signs that a new thermostat is needed
- The heating or cooling system won’t switch on or off.
- The thermometer’s reading is off.
- recently increased energy costs.

- The thermostat is at least ten years old.
What can I look for to see whether my thermostat is stuck open?
Two categories of thermostat problems are discernible in their signs: a stuck-open thermostat Driving, especially in the cold on the highway, causes the engine temperature to drop below normal when the thermostat is stuck open. Lack of heat from the heating system can also be brought on by a stuck-open thermostat. The Check Engine light might also illuminate.
The thermostat may be stuck closed, which could cause the engine to overheat.
In addition to these two scenarios, if the thermostat casing is leaking coolant, the thermostat may also need to be changed.
