🔧 Product Description
Genuine coolant filler cap used on selected Volvo Penta radiator-package installations. This is a cooling-system cap rather than an engine-oil filler cap. It closes the radiator or expansion filling point and maintains the specified cooling-system seal.

⚙️ Key Features
- Genuine Volvo Penta cooling-system filler cap
- Confirmed in TD520GE and TD720GE radiator packages
- Correct factory neck and sealing dimensions
- Helps retain coolant and cooling-system pressure
- Provides access for coolant filling and inspection
🔌 Function
The cap seals the coolant filling point and helps prevent coolant loss, contamination and pressure leakage.
⚠️ Common Signs of Failure
- Coolant staining around the filler neck
- Cap will not lock securely
- Damaged or hardened seal
- Cooling system failing to hold pressure
- Coolant loss through the filler neck
🛠️ Service Notes
- Fit the cap specified for that filler on your engine — caps that look alike differ in seal, venting and pressure rating, and a substitute may hold the system at the wrong pressure or not seal at all
- Wipe the filler neck and check its sealing land for nicks, corrosion and distortion before fitting; many apparent cap leaks are actually neck leaks
- Check the cap's seal is soft and unbroken, and that any vent or breather hole through the cap is clear
- Seat the cap fully, to its stop or lock position — a cap left part-turned will weep, and on a pressurised system can lift
- Never open a cap on a hot pressurised system; let it cool first
