Better than the apparent OEM cap for the radiator reservoir on my '92 Chevy G-30 350CID. It's design is easier to grip and it has a nice gasket for secure fitment.

This is an exact fit to replace the cap on a factory reservoir for a 1989 Chevy Blazer

Es una tapa de plástico, no es la gran cosa. Le queda al depósito de anticongelante de un Chevy Nova 1978. Tiene las ventilas y poco más.
