Permanent Coolant Leak Repair with K-Seal
Coolant leaks don’t have to result in costly repair bills – simply add K-Seal to your coolant system for a quick and permanent fix. K-Seal is scientifically tested, trusted by millions of customers worldwide, and the only coolant leak repair fluid carried by the AA, the UK’s largest roadside repair company.
Just pour & go
K-Seal couldn’t be simpler to use. Just shake the bottle, add the fluid to your coolant system, and run your engine as normal. K-Seal’s unique formula will seek out holes and cracks and permanently seal them, with no adverse impact on the efficiency of your engine cooling.
We have 30 different products on our shelf that claim to fix leaks. Me and my staff grab K-Seal over any product when a garage calls or someone walks in asking if we have a coolant stop leak. Thank you for making a great product that we can stand behind with confidence!

Please use extreme caution when working on a hot cooling system as hot coolant and gases could cause injury. If in doubt please consult a qualified mechanic.
