What to do if the old Jetta's water temperature reaches 130?
2 Answers
The old Jetta's water temperature reaching 130 is generally caused by reasons such as water leakage, thermostat not opening, no circulation, or radiator issues. Therefore, when repairing, start with the simple aspects first, such as checking for water leakage. Due to overheating and insufficient coolant, it is necessary to first fill up with water and then start troubleshooting.
My old Jetta's coolant temperature has reached 130°C? That's extremely dangerous! Normally the engine operates around 90°C, 130°C is way too high and could easily damage the engine block. I recommend pulling over immediately, turning off the engine, and activating hazard lights to warn other drivers. Wait about ten minutes for the car to cool down before opening the hood to check the coolant level. If it's low, add some distilled water as an emergency measure but don't open the radiator cap when hot to prevent burns. Common causes include water pump leaks, stuck thermostat, or non-functioning cooling fan (you can try turning on the AC to see if it activates the fan). Never continue driving as it may cause piston damage or even total engine failure. Best to call a tow truck for professional inspection and replacement of worn components. Regular maintenance including cooling system checks and coolant replacement can prevent this. Safety first - never take this lightly.
