Description
Overview:
Coolant Leak Repair K‐Seal 236ml is a liquid sealant for fast, lasting repair of leaks in water‐cooled engines. The formula is a fine micro‐particle suspension that circulates with the coolant and bonds to leaking areas as the engine warms, helping to seal hairline cracks and pinholes in radiators, heater cores, water pumps, and core (freeze) plugs. It is suitable for cars, vans, trucks, and plant and construction machinery with pressurised cooling systems. Compatible with all common antifreeze and coolant types, it can be added directly without draining or flushing. The 8 fl oz (approx. 236 ml) bottle is sized for convenient single‐system treatment. Backed by a lifetime guarantee for engine safety, it provides an easy, workshop‐friendly fix that keeps equipment running reliably.
Key Features:
- Seals small leaks in radiators, heater cores, water pumps, and core (freeze) plugs
- Works with all antifreeze and coolant types, including ethylene glycol and propylene glycol blends (OAT/HOAT compatible)
- No need to drain or flush the cooling system before use; pour and go
- Micro‐particle formulation seeks out and seals pinholes and hairline cracks for a long‐lasting repair
- Suitable for cars, light commercial vehicles, HGVs, and water‐cooled plant and construction machinery
- Helps stabilise coolant loss to reduce overheating risk and downtime
- Can be used with coolant or plain water present in the system
- 8 fl oz (approx. 236 ml) bottle treats a typical vehicle cooling system
- Lifetime guarantee for engine safety for added confidence
- Simple application with no special tools required
Typical Applications:
Everyday repairs where a cooling system has a minor leak and downtime must be kept low. Commonly used for roadside or workshop fixes on passenger cars, vans, tipper trucks, loaders, telehandlers, excavators, and other water‐cooled plant. Ideal for sealing seepage at radiator cores, heater matrices, water pump housings, hose junctions, and core plugs to help maintain operating temperature and prevent coolant loss.
