K-Seal HD permanent coolant repair is the brand that motor stockists recommend with confidence to their customers with buses, coaches and HGVs. K-Seal HD can be used in the workshop, on the road or on site so the vehicle can be put back into service almost immediately, avoiding expensive downtime. Always have a bottle on standby for every vehicle. Fixes most leaks in all types of water cooled engine including cracked heads, head gasket failures, cracked blocks, radiators, heater cores and water pumps.
Effectively this is the same formulation as the standard K5501 236ml bottle of K-Seal but is simply double the volume. Cooling systems with capacities above 20 litres should use the HD 472ml size as its a more cost effective solution.

FAQs
Is K-Seal compatible with all types of coolant?
Yes. K-Seal does not react with coolant or other additives that may already be present in the system.
Is there any special preparation I need to do before using K-Seal?
Unlike other block sealers, K-Seal is a simple ‘pour & go’ solution. Shake the bottle well and then add the entire contents to the cooling system where you would normally top up the coolant/water.
How much K-Seal do I need?
1 standard bottle of K-Seal (236ml/8floz) will treat cooling systems with a capacity up to 20 litres (this covers motorbikes up to light commercial vehicles). For larger cooling systems use our Heavy Duty (472ml/16floz) size K-Seal.
