Filtration

Coolant Filters and Conditioners

Spin-on coolant filters with and without chemical additive, for engines that specify coolant filtration. The additive charge is stated per element.

Features

  • Coolant filters trap casting debris and scale that would otherwise erode the water pump seal and block the oil cooler.
  • Additive-charged elements release corrosion inhibitor as coolant passes, keeping liner protection in range between coolant changes.
  • Additive charge is matched to system volume; an over-charged system drops additive out of solution and blocks passages.
  • Non-charged elements are used where the coolant already carries a full additive package, and mixing the two regimes causes gelling.
  • Coolant condition is checked with test strips at service so filtration and additive decisions rest on readings.
