Description
Radium Dual Fluid Lock Catch Can Kit - Ford Fiesta ST 13-18
Application: Ford Fiesta ST (2014-2019)
Part Type: Dual Fluid Lock oil catch can kit (PCV + crankcase)
Part Number: 20-0379-FL
Radium catch cans separate oil and water condensation from crankcase gases before they reach the intake, preventing oil build-up in the intake, intercooler, throttle body and intake manifold. Cleaner inlet air raises effective octane and improves performance, lowers hydrocarbon emissions, and the closed system keeps oil vapour out of the cabin.
The 20-0379-FL dual kit combines the 20-0377-FL PCV kit and the 20-0378-FL crankcase kit, and is Radium's recommendation for maximum engine protection. The PCV can runs inline with the PCV valve and mounts to the front right-hand motor mount; the crankcase can runs inline with the crankcase vent and mounts to the ECU studs on the rear left-hand side. Both fit under the OEM engine cover.
Key Features
- Fluid Lock: Patented design prevents overfilling and holds collected fluid until emptied
- Large Ports: 10AN ORB inlet/outlet, 4AN ORB drain
- 2-Step Baffling: Two-step oil separation
- Dipstick: O-ring sealed dipstick for easy inspection
- Direct Fitment: No drilling required
- Complete System: Covers both the PCV and crankcase vent circuits
What's Included
- 20-0377-FL PCV catch can kit
- 20-0378-FL crankcase catch can kit
- Each kit includes: anodised oil catch can with integrated condenser and dipstick, Fiesta ST-specific anodised aluminium bracket, anodised aluminium AN adapter fittings and hose ends, PCV hose for custom applications, and stainless steel mounting hardware
Optional Parts
- Radium Catch Can Petcock Drain Kit (20-0024) – Drain the can without removing the reservoir, where space allows
Important Notes
- RHD vehicles: the ECU cover near the battery is metal, and Radium's instructions state it must be modified to fit the crankcase catch can
- There is no set emptying interval – check the dipstick from 3-4 weeks and adjust; PCV systems typically collect more than CCV systems
- Excessive collection can indicate an engine problem such as blow-by, an overfilled crankcase, poor breather placement or a PCV valve that does not close under load
- Installation instructions are available in the Instructions tab
