Why is my Lexus IS250 overheating?

Possible Causes of Overheating in a Lexus IS250
Based on the search results, there are several potential causes for your Lexus IS250 overheating. Here are some possible reasons:
1. Coolant Mixture: Ensure that the coolant in your vehicle is a 50/50 mixture of coolant and water. Too much coolant can cause overheating.
2. Malfunctioning Fans: Check if the fans in your vehicle are working properly. If the fans are not coming on, it suggests that the coolant sensor on the radiator may not be getting hot or has failed.
3. Thermostat: A faulty thermostat can cause overheating. If the thermostat is stuck closed, it can prevent coolant from flowing through the engine and radiator properly.
4. Water Pump: A malfunctioning water pump can result in inadequate coolant circulation, leading to overheating.
5. Blockage in the Cooling System: A blockage in the cooling system can restrict the flow of coolant, causing the engine to overheat.
6. Head Gasket Issues: Symptoms such as coolant in the oil, overflowing coolant reservoir, misfire between cylinders, and overheating under load can indicate head gasket problems.
7. Air in the Cooling System: Air trapped in the cooling system can disrupt proper coolant circulation and lead to overheating.
It is important to note that these are potential causes based on the information provided in the search results. To accurately diagnose and address the issue, it is recommended to consult with a qualified mechanic or take your vehicle to a Lexus dealership for a thorough inspection and diagnosis.
