The coolant may not be circulating in the radiator due to several reasons, including a malfunctioning water pump, a clogged radiator or hoses, or a stuck thermostat. Additionally, low coolant levels or air trapped in the system can also impede circulation. It's essential to diagnose the issue promptly to prevent overheating and potential engine damage. Regular maintenance can help identify and resolve these issues before they become serious.
Low coolant? Cooling fan not working? Radiator restricted or plugged? Water pump not circulating coolant? Defective radiator cap? Low coolant? Cooling fan not working? Radiator restricted or plugged? Water pump not circulating coolant? Defective radiator cap?
Could be a plugged or restricted radiator Low coolant? Water pump not circulating coolant?
Low coolant? Cooling fans not working? Water pump not circulating coolant? Radiator plugged or restricted?
It could be the radiator is clogged. The thermostat could be bad (prevents the coolant from circulating from radiator to engine block)
Low coolant level? Cooling fan not working? Thermostat not opening fully? Water pump not circulating coolant? Plugged or restricted radiator? Defective radiator cap?
Low coolant? Thermostat not opening? Radiator plugged or restricted? System airbound? Water pump not circulating coolant? Hoses collapsing? Defective radiator cap?
You should see the coolant circulating in the radiator when the car is running
Possible, but rare. The coolant may be circulating too fast to have time to dissipate heat when going through the radiator.Possible, but rare. The coolant may be circulating too fast to have time to dissipate heat when going through the radiator.
