It me again....I bought some test strips to check the coolant. The service guy at Cummins told me I should change the coolant filters to. (original). The filters they sold me are "8 units". If the coolant test good, is it still ok to change the filters with "charged Water Filters"? The mechanic said it will not hurt a thing. the charge is time released and I would just extend the next change...any thoughts?
