How to fix an engine block or radiator leak with K&W® Block Seal

Leaks from your engine block & radiator can be time consuming to fix not to mention very expensive, but with K&W Permanent Metallic™ Block Seal, you can fix the problem yourself and get back on the road without an expensive repair bill. Its guaranteed. Engine block and radiator leaks can show up as a lot of different symptoms. Such as colored fluid dripping from your exhaust, white smoke coming from your exhaust pipe, a greasy film on the inside of your windshield which gets worse with the defroster on, a colored liquid dripping on the passenger floor from under the dash, a milky substance on your oil cap or dipstick or bubbles in the radiator recovery tank sometimes seen from coming out from under the recovery tank cap. K&W Block Seal can help. Block Seal creates a permanent molecular bond that's as strong as steel. It can seal cracks and holes in cast iron and aluminum engine blocks, head gaskets and freeze plugs. As well as aluminum bi-material radiators and heater cores. And even though most do-it-yourselfers can use it successfully, Block Seal is a professional grade formula that withstands extreme pressure and temperatures. Before you start gather your tools and read all of the product instructions. Not following directions exactly could cause severe engine damage. First: We're going to drain the cooling system to remove any antifreeze. Block Seal contains sodium silicate which is not compatible with antifreeze. So remember do not add it to antifreeze, your engine oil or fuel. With the engine cool remove the thermostat and radiator cap. Then, replace the thermostat housing. Set the heater control to maximum heat and idle the engine until its warm. Turn off the engine and then drain the radiator. Make sure to observe local laws and regulations for proper disposal. Do not pour coolant on the ground or in a storm drain. Close the radiator drain and refill the radiator with water. Idle for 5 minutes to flush any excess antifreeze from the system. Turn off the engine and drain the cooling system. Repeat this process until the water runs clear. For best results, flush the cooling system with K&W 7 minute rapid flush cooling system cleaner. Shake the block seal can well and then mix it with 3 quarts hot water in a separate container. Small engines may require less than 3 quarts of hot water mixture. A 1 gallon milk or water container works great. If you've been seeing white smoke in your exhaust or think coolant is leaking into a cylinder remove the spark plugs and check for orange or white crystals or fluid. Remove any effected spark plugs and disable the fuel injection to the effected cylinders before the next step. Add the block seal and water mixture to your radiator. Do not pour the mixture into the overflow tank. If there isn't a radiator cap, detach the upper radiator hose and add the mix directly into the hose, then reattach the hose. Start the engine and immediately top off the cooling system with water. If the vehicle starts to overheat, turn the engine off, allow it to cool, top with water and restart. Replace the radiator cap and reconnect the radiator hose and then idle the engine for 20-30 minutes. Do not drive the vehicle or rev the engine. Stop the engine, let it cool and remove the radiator cap and open the radiator drain. Reinstall any spark plugs you've removed. Drain the cooling system, do not flush. With the radiator cap and drain open, allow the drain cooling system to cure for 24 hours. After Block Seal has been allowed to cure for 24 hours, flush the cooling system with water until it runs clear. Reinstall the thermostat and drain the water. Then refill with fresh antifreeze and water solution at the correct concentration and your good to go. If the leak persists for more than a week, you can repeat the treatment with Block Seal. But, if your loosing more than a half a gallon of coolant in 30 minutes, no cooling system additive will be able to fix your leak and you'll need a professional repair. And if your not comfortable with following these directions, take your can of Block Seal to your favorite repair shop and ask them to service your vehicle with K&W Block Seal. So Stop Leaks and Start Driving with K&W Permanent Metallic™ Block Seal
