What Does This Radiator / Oil Tank Cap Do?
Pressure caps for the radiator and hydraulic oil tank. The radiator cap maintains the cooling system at the designed pressure to raise the boiling point of the coolant. The oil tank cap seals the hydraulic reservoir fill point. Both must maintain an airtight seal while allowing controlled pressure relief.
Possible Radiator / Oil Tank Cap Problem Symptoms
If your machine is showing any of the following, a faulty radiator / oil tank cap may be the cause:
- Coolant boiling or overheating at temperatures below the normal boiling point due to low system pressure
- Coolant or hydraulic oil leaking past the cap seal at the fill opening
- Cap spring pressure found to be weak or absent when tested — not holding rated pressure
- Hydraulic oil becoming aerated or foamy due to air being drawn in past a faulty tank cap seal
