Description
Overview
K-Seal Coolant Leak Repair 236ml treats small leaks in water-cooled engine systems, including radiators, head gaskets, heater cores and water pump casings. Its ceramic microfibre and copper-particle formula circulates with the coolant and seals leaks as it reaches them.
Features
- One 236ml bottle treats cooling systems up to 20L.
- Pour-in application without draining or flushing a normally flowing system.
- Compatible with all antifreeze and coolant types.
- Targets leaks in engine blocks, radiators and freeze plugs.
Specifications and Materials
Includes one 236ml bottle of ceramic-based coolant leak sealant. Shake vigorously, add to the radiator or expansion tank, then run the engine to normal operating temperature.
Part number: K5501.
Read the manufacturer’s coolant leak repair guide for application instructions.
Compatibility and Fitment
Check cooling-system capacity before use. This standard bottle covers systems up to 20L; larger heavy vehicle engines require the 472ml HD version. Add only to the coolant circuit, never the engine oil.

For larger commercial engine cooling systems, select the heavy-duty size instead.

Compliance and Safety
Never open a hot, pressurised radiator or expansion tank. If coolant circulation is restricted, investigate and flush the system before treatment. Keep the liquid away from eyes and drains.
Trailer Applications
Workshops use K-Seal Coolant Leak Repair 236ml on water-cooled tow vehicles, yard vehicles and light commercial fleet support equipment. For trucks and heavy plant with larger cooling systems, choose the HD variant.

Why Choose ICS Trailers
The key choice with this sealant is engine cooling capacity: 236ml covers up to 20L, while larger systems need a different size. ICS Trailers can help compare engine and cooling-system details before you order, especially when maintaining mixed fleets of tow vehicles and heavier equipment.
- Consider the coolant leak location alongside hoses, radiator connections and nearby service items.
- Send your vehicle model and coolant capacity so we can help narrow down the suitable treatment size.
