K-Seal ULTIMATE K3501 Head Gasket Repair is a game-changing solution to one of the most common and costly engine problems - blown head gaskets, cracked heads and blocks, and porous engine blocks. This powerful formula is designed to provide a permanent fix for these issues, guaranteed for the life of your engine, or your money back!

The unique formula of K-Seal ULTIMATE works with all water-cooled engines, making it suitable for use in cars, SUVs, small trucks, and more. The best part is that there is no need to drain or flush your cooling system, and it doesn’t matter what kind of antifreeze or coolant you’ve used previously. Simply shake the bottle, pour K-Seal ULTIMATE into your cooling system, and you’re back on the road in no time.

With just one bottle of K-Seal ULTIMATE, you can fix blown head gaskets and cracked heads in most cars, SUVs, and small trucks. For larger engines, two bottles are recommended. This versatile solution can be used in hot or cold engines, and will not be affected by any coolant, antifreeze, or other additives already in the cooling system.

How to use K-Seal ULTIMATE

1. Shake the bottle

K-Seal ULTIMATE will naturally separate if left to sit for an extended period. It’s important to shake the bottle for 30 seconds before application, to ensure an effective treatment.

2. Pour into the radiator

Pour K-Seal ULTIMATE into your radiator (but not directly onto the radiator core) or header / expansion tank. K-Seal ULTIMATE will not be affected by any coolant, antifreeze or other additives already in the cooling system. It can be used in hot or cold engines.

3. Start your engine and get back on the road!

Once you have applied K-Seal ULTIMATE to your coolant system, simply run your engine as normal.
