Because of the Bar's Leaks 2X Action formula, the product has additives to work on any of the three types of rear main seal, no matter the material.

The seal restorer additive restores seal size, flexibility and elasticity lost due to engine heat, age and high mileage. The seal polymer works by building a polymeric film around the rear main seal and also filling in any groove worn into the crankshaft by the seal.

No, you must first drain and flush the entire cooling system, including the overflow tank and refill with water. All antifreeze must be removed from cooling system or clogging could occur.

The more in depth answer is: A rear main seal, also known as a main seal or rear main bearing seal is located between the engine and transmission. The crankshaft (the internal engine part that the pistons are connected to) sticks out of the rear of the engine, and the flywheel & transmission bolt to this crankshaft. The engine oil lubricates the crankshaft, pistons and other internal parts of the engine.

For most rear wheel drive vehicles the transmission is removed to replace the seal. On front wheel drive vehicles, it is usually easiest to remove the engine to gain access to replacing the seal. Either way, this is an expensive procedure.

Engine Repair contains a combination of the best performance additives to repair the most common oil-related problems. Engine Repair restores lost compression and power, reduces noise and oil consumption, while improving the performance of worn cylinders, rings, bearings, and seals.

No. Unlike our cooling system product, Bar's Leaks Transmission Repair has no particles to plug the leak, it works chemically to stop leaks in gaskets and seals.

After time, transmission seals tend to dry out and shrink and internal parts become worn. Bar's Leaks Automatic Transmission Repair reduces rough shifting and friction, while eliminating slip, controlling temperature, and repairing shudder, chatter and whining. Premium high mileage formula restores transmission performance

Depending on the severity of the leak the first thing you may notice is the oil level going down. The next thing that happens is spotting, where you will find oil spots, located on the driveway or garage. While looking under the vehicle around the area where the engine and transmission connect, you will find oil dripping, or a oil residue with dirt caked on this part of the vehicle. Most noticeably under the oil pan and the front of the transmission.

Our A/C Leak Sealer (UVS-1), Stop Leak & Detector (LDS-1), and the leak sealers included in many of our refrigerants seal leaks in rubber components such as O-rings, hoses and gaskets. They work by swelling the rubber in these components to close the holes. Our Maxi Seal (MRL-2) seals both rubber and metal leaks. The metal leak sealer works by reacting with air and condensed moisture outside the system at the site of the leak.

Yes, Bar's Leaks is one of the only transmission stop leaks that is compatible with all petroleum-based transmission fluids including synthetics.

No. Unlike our cooling system product, Bar's Leaks Engine Repair has no particles to plug the leak, it works chemically to stop leaks in gaskets and seals.

Yes, you can use this product to help stop leaks in a manual transmission as long as it uses an automatic type transmission fluid. Use ? the bottle for most applications.

Yes, it is compatible with ALL types and brands of antifreeze including conventional green or blue (Silicate-Based) and extended life red/orange or yellow (OAT/HOAT) coolant. Also works in systems containing only water. Systems that are dirty or partially clogged, a flush is recommended before use.

Most of the time it is put on incorrectly. The mouthpiece should not be shoved all the way to the end of the retainer collar. There are two notches on the inside of the Bite ValveTM that the retainer collar fits into. This will most likely stop the leaking.

That depends. Many of our customers have specialized to the point where they only find leaks. They pass the repair job off to another pool repair company that wants to specialize in repairs, or they may send the repair back to the pool service company that referred the customer to them.

Yes, Mobil Clean High Mileage can still be used. The extra seal conditioner may help to prevent a leak later on and will not cause problems in your vehicle. Mobil Clean 5000 has a boosted level of cleaning performance to help prevent the formation of sludge and harmful deposits and provides outstanding wear protection of critical engine parts during today's longer service intervals. Mobil Clean High Mileage is designed especially for higher mileage (75,000 miles-plus) vehicles.

Our Self-Sealing Refrigerant process cannot seal extremely large leaks or ruptures. A good guideline to follow is that it should not be used for leaks that individually release more than 1 pound of refrigerant per hour. It should be noted that Cryoseal™ will not seal dynamic shaft seal leaks on external drive shafts.
