كلكم ترتكبون نفس الخطأ عند تغيير ماء الرادياتير toyota cooling system flush and coolant change

DIY Car Maintenance Series (Episode 2) Read the notes in the description carefully regarding the correct way to change your radiator coolant. First: Cars without a radiator cap and only have a water reservoir are treated as the radiator, following the exact same steps. Second: For cars without a drain plug, especially older models, drain the coolant using a hose, following the exact same steps. Third: For cars with a lot of dirt and rust, the process should be repeated more than twice. Use regular tap water (not distilled) until the water runs clear, then distilled water before the final step, and finally, add green or red coolant. Fourth: Using distilled water is only necessary to save on the high cost of green or red coolant. It's fine to use green or red coolant at all stages. Fifth: You must wait until the car has cooled down before adding coolant at all stages. Do not add coolant while the car is hot. Allow a period of time between each stage until the car has cooled down to ensure your safety and the safety of the engine.
