* Low coolant level: If the coolant level is too low, the antifreeze won't be able to circulate properly and reach the engine. Check the coolant level and add more if necessary.
* Clogged coolant lines: Clogged coolant lines can prevent the antifreeze from flowing through the system. This can be caused by rust, sediment, or debris. Flush the coolant system to remove any clogs.
* Faulty thermostat: A faulty thermostat can prevent the antifreeze from flowing into the engine. The thermostat is a valve that regulates the flow of coolant. If it's stuck closed, the antifreeze won't be able to circulate properly. Replace the thermostat if it's faulty.
* Water pump failure: The water pump is responsible for circulating the coolant throughout the system. If the water pump fails, the antifreeze won't be able to circulate properly and reach the engine. Replace the water pump if it's failed.
* Head gasket failure: A head gasket failure can cause coolant to leak into the combustion chambers. This can prevent the antifreeze from circulating properly and reaching the engine. Replace the head gasket if it's failed.
Note: If you're not sure what's causing the antifreeze not to go to the engine, it's best to take your car to a mechanic for diagnosis and repair.
