Avoid Expensive Downtime! Keep K-Seal^™ HD on Hand!

K-Seal Heavy Duty One Step Permanent Coolant Leak Repair can help keep commercial vehicles on the road instead of stuck in the workshop losing money.  K-Seal is suitable for use with all water cooled engines including:

• Trucks
• Buses
• Agricultural Equipment
• Construction Vehicles

One 16oz bottle of K-Seal will treat cooling systems with a capacity up to 50 quarts.  (Use the 8oz K-Seal for cooling systems less than 20 quarts).  K-Seal HD will permanently seal leaks in the head gasket, block, cylinder head, radiator, heater core, freeze plugs and water pump casing. 

Simple to use, just SHAKE, POUR & GO!

Here's what Commercial Vehicle Workshop Magazine had to say when they tested K-Seal on a Scania coach with an external leak from the head:

"Having seen the results I am very impressed with this product.  I think it would be advisable for any workshop to stock K-Seal, as more times than not, it can solve a problem quicker and at a smaller cost to the customer than mechanical repair."  (CVW Magazine, September 2008)

Use K-Seal HD in cooling systems greater than 20 quarts and up to 50 quarts.  In very large cooling systems above 50 quarts capacity it may be necessary to use 2 bottles of K-Seal HD. 

Always keep a bottle of K-Seal HD to hand so that you can treat leaks immediately you spot them.  In that way you can keep your heavt duty vehicle in service instead of losing money while it is out of action.

Important: If your vehicle's cooling system is fitted with a water filter you may wish to disconnect or bypass the filter before treating the cooling system with K-Seal.   If you treat the cooling system with the water filter in place we recommend replacing the filter at the next available oportunity.
