Troubleshooting & FAQ for Hitachi Cooling Systems

How do I know if my Hitachi 707-98-11700 seal needs replacement?

Visible leakage around the radiator base or a sudden drop in coolant pressure are primary indicators. If you notice oily residue in the coolant or steam escaping from the radiator housing, the 7079811700 seal has likely reached its wear limit. Immediate replacement is recommended to avoid engine head gasket failure.

When should the radiator oil seal be inspected?

We recommend inspecting all seals including the 707-98-11700 every 500 operating hours. During a major engine rebuild or radiator cleaning, always replace the old seals with new OEM-standard 7079811700 kits to ensure a leak-proof seal during the next cycle.
