If you need to top up coolant in a car, which liquid should you use?

Correct answer

Coolant meeting the manufacturer’s specifications.

The manufacturer-specified coolant, in the stated mixture or ready to use. Do not add fuel or improvise an incompatible mixture. Check the level with the engine cold and follow markings and manual instructions; do not open the reservoir with the system hot or fill above the maximum.
