Idle engine for 20 minutes then turn off and let cool for 20 minutes, repeat this run-cycle three times. Next, drive vehicle for 20 minutes with sealer in system. Then, drain Dura-Seal® out, (it's not required to flush Dura-Seal out, just drain), later refill with coolant and Dura-Seal® Liquid-Ice. First-time applications have a 98% success rate. Only 2% require a second *free application, (*which is covered under warranty). Typical repair-life is 5 years.
Over the past 18 years, Dura-Seal® has helped over half a million customers world-wide and has become the leader in automotive head gasket sealer manufacturering by offering the most advanced sealer products you can buy...

Dura-Seal
® is more advanced than other head gasket repair sealers. Our Head Gasket Repair Sealer stays flexible when cured so it expands and contracts with today's aluminum engines and lasts up to 5 years. We have a *Money Back Guarantee and provide you with a Free Replacement Warranty on all Head Gasket Repair Sealers and Oil Stop Leaks if you need more sealer to then typical to achieve a full-seal, (*certain conditions like S/H may apply, see Terms). So if you don't get a full seal, call us and we'll send you another free application to get you to the finish line...
Drain coolant system and run clean water through entire system. This will remove most contaminates. If you've used a water glass/silicate based sealer prior to using Dura-Seal®, you will need to purchase our "Water-glass Flush Agent" before using our sealer.

It's not required to remove the thermostat as our sealer cannot cure or clog that area, but, if left-in, it will slow the process by restricting flow. Next, pour the Dura-Seal, and Extreme Powder Pack into the radiator, (no radiator cap?) disconnect upper radiator hose from engine and pour sealers into hose (they will flow to radiator). Fill system with water.
Leaking coolant from your Intake Manifold?
4, 6, & 8 Cyl. engines. Used safely on aluminum, steel, or plastic intakes...

Plus our Automotive Tech's are available Mon -Fri. 9am to 6pm EST at: 706-400-0897. As a general rule, anytime your working on your coolant system of your vehicle you should always drain your old coolant out and at least run some clean water through the system before using our sealers to remove any contaminates like hydro-carbons, scale and oil residue. That being said, here's a brief description of how to perform an average DuraSeal Head Gasket Repair;

INSTRUCTIONS FOR USING OUR HEAD GASKET REPAIR SEALER:

IMPORTANT NOTES: (1) Do not use the “overflow-tank”. (2) If the vehicle has no radiator cap, use “upper-radiator hose” to add sealers and water. (3) The repair process is more efficient with thermostat out. However, removal is not always possible on certain models so, the thermostat can be left-in during the repair process, (this will be discussed later).

1). Start with a cool engine. If your vehicle has a radiator cap located on the radiator, remove it now and leave off during draining, (you will use the cap opening to pour the sealers and water into the system later). If your vehicle only has an over-flow tank and does not have a radiator cap, disconnect the upper radiator hose from the “engine-side” leaving the other end still attached, (you will use this hose to pour the sealers into your system later).

(2). Drain coolant system
, if you have used any other type of sealer be sure to use our "Water-Glass Flush Agent" to remove any water-glass based sealers from your engine. (disconnect lower radiator hose from the radiator, allowing engine block and radiator to drain). You should also remove thermostat at this time, and leave out during the repair. Be sure to reinstall housing with thermostat left-out. *After draining, run clean water through radiator and engine block. If vehicle has the newer style thermostat, (see picture #3), you will need to apply a small amount of ATV Automotive Silicone between the thermostat housing and the engine block to maintain the seal while the thermostat is out during the repair process.
*If you cannot remove the thermostat, you may leave it in. If you do leave it in, after draining all fluids as directed in “Step-2”, reconnect lower-hose, refill system with clean water, idle engine for 15 minutes, then allow to cool and re-drain a second time. Then, move on to “Step-3”.
NOTE: *If repairing a Subaru, you MUST flush-out the heater-core at this time! Subaru heater cores accumulate dirt and grime which adversely affect the overall sealing process! To flush, simply locate the two black heater hoses between the engine and the firewall, (they will be within a few inches of each other.) < See picture at left. Simply disconnect both hoses and using a garden hose flush clean water into each metal tube and through core until water runs out clear. Then reattach hoses.

(3). If you purchased Dura-Seal Coolant Flush Agent, add now and follow the directions on the bottle, if you do not have the flush agent, begin “Step-4” now.

(4). Be sure to reconnect lower-hose and begin the repair process by pouring all Dura-Seal Head, Block or Intake Manifold Liquid Sealer contents included with your repair kit and entire packet(s) of Dura-Seal Extreme Powder Additive into your coolant system via the radiator cap, (if you do not have a radiator cap) use the upper radiator hose. Simply disconnect upper-hose from the engine-side of the hose leaving it attached to the radiator. Next, completely fill the system with clean water, no coolant at this time. Replace radiator cap and/or hose.

(5).
Idle in “park” with heater on “high” for three 20 minute run-cycles with 20 minute cool-downs between them, (example; 20 minutes-on, 20 minutes-off). Do not allow to overheat, (if it begins to overheat, turn off engine and allow to cool then continue any remaining time left on that run cycle, allow cool-down. Then, move on to next run cycle). When done with all run cycles, be sure vehicle is road worthy, safe to operate and drive for 15 minutes with sealer solution still in vehicle, do not exceed 45 MPH. If you still have symptoms like white smoke or coolant loss, add water if necessary and repeat “Step-5” up to 3 times if needed. Symptoms should go away.

(6).
When finished with “Step-5”, whether or-not all symptoms are gone! let engine cool down and drain-out all used sealer solution/water out of the system following Step#2 listed above. (Remember, if you left the thermostat in during the repair, you MUST refill with clean water, idle 15 minutes and re-drain that second time as stated in “Step-2”). Next, disconnect “upper” and “lower” hoses and allow your system to air-dry for at least 4 hours, overnight air-dry is ok too! Then, reinstall your thermostat, (NOTE: Northstar engines will want to overheat when operating without a thermostat). If no freezing weather exists refill system with just water, if outside air is freezing, be sure to use antifreeze. Take vehicle for test drive to check new seal, thermostat should be in at this time. If you have a full 100% seal, you can add coolant/antifreeze to system later that day if needed. *If you do not have a full seal, simply call Dura-Seal customer service Mon.-Fri. 9am. to 5pm. EST 706-400-0067 to receive another application, as some vehicles may require another treatment to fully seal the leak.

*NOTE: Additional treatments are custom made at our facility to be stronger then your last treatment…


*If you purchased our Dura-Seal Oil Stop Leak you may add to engine oil at this time...
*If you purchased the Dura-Seal Liquid-Ice, do not add until 48 hours after a successful repair., just pour into overflow tank .
