Among foreign models, car owners have good reviews about the Metal Inkar model from a Polish manufacturer.
These products work great in the Chevrolet Niva cooling system, the engine warms up quickly, there are no complaints.
The only negative is that the case is made in two versions - plastic and brass. The second option is not very favored by drivers, although it also works well in a circuit.
