So I need to flush all the coolant out of the radiator and hoses, most
garages have systems that do not work with since it has an older
strange system to them.

How is everyone doing it?

One person suggested using an air compressor to blow the remaining
coolant out of the lines.

Most of the garages are now using a vacuum method but told it might
not work on the van.

Any ideas?

Thanks,
