Applications
Fits coolant filter heads on heavy-duty diesel engines including:
- Mack EM/E-series and ENDT engines (1980s-1990s pre-E7 era)
- Caterpillar industrial and on-highway diesel installations using 3/4″-20 UNEF heads
- Older International / Ford diesel coolant-filter retrofits
Confirm DCA chemistry compatibility (DCA4+ vs. ELC/extended-life) with your coolant before installation. Mismatched chemistries can cause additive drop-out.
