Importance of Regular Maintenance of Engine Coolant
Maintaining your engine coolant is key for your car’s functioning. Ignoring this can lead to costly repairs.
The cooling system includes the radiator, water pump, thermostat, and most importantly, the coolant. The coolant moves through the engine block and absorbs heat. Then, it goes back to the radiator, is cooled, and routed again.
You need to check the level and condition of the coolant regularly. Do not mix different types of coolants as they are created for a purpose.
If you’re thinking about using G40 instead of G12 coolant, don’t. Manufacturers suggest only using what’s in the owner’s manual.
It’s not worth the risk of your engine overheating faster than a politician caught in a lie before switching G12 for G40.
