Yes, using poor-quality coolant o r contaminated coolant can cause radiator leaks:

Rust and Corrosion: Cheap o r diluted coolant may not have the right additives to prevent rust and corrosion. This can lead to the formation of rust inside the radiator, which eventually causes leaks.
Clogging: Contaminated coolant can cause blockages in the radiator, which reduces its efficiency and can lead to overheating o r leaks.
