J-B Weld 2120 Radiator Repair Kit

Product Information

However, pressurized systems were also more complex, and far more susceptible to damage - as the cooling fluid was under pressure, even minor damage in the cooling system like a single rifle-calibre bullet hole, would cause the liquid to rapidly spray out of the hole. Failures of the cooling systems were, by far, the leading cause of engine failures. Radweld also prevents future leaks to help keep your car on the road for longer. By treating areas of corrosion and pitting at the source, the product effectively extends the life of your coolant/antifreeze and individual components within the cooling system, which helps to prevent future leaks while maintaining the efficacy of engine cooling for longer. An aircraft radiator contained in a duct heats the air passing through, causing the air to expand and gain velocity. This is called the Meredith effect, and high-performance piston aircraft with well-designed low-drag radiators (notably the P-51 Mustang) derive thrust from it. The thrust was significant enough to offset the drag of the duct the radiator was enclosed in and allowed the aircraft to achieve zero cooling drag. At one point, there were even plans to equip the Supermarine Spitfire with an afterburner, by injecting fuel into the exhaust duct after the radiator and igniting it [ citation needed]. Afterburning is achieved by injecting additional fuel into the engine downstream of the main combustion cycle. Holts develop products for you right here in the UK, based on the ever-changing needs of the car market, so they’re easy to use. How it Works Surface radiators have also been used by a few high-speed racing cars, such as Malcolm Campbell's Blue Bird of 1928.

Some vintage cars use radiator cores made from coiled tube, a less efficient but simpler construction. The most obvious, and common, solution to this problem was to run the entire cooling system under pressure. This maintained the specific heat capacity at a constant value, while the outside air temperature continued to drop. Such systems thus improved cooling capability as they climbed. For most uses, this solved the problem of cooling high-performance piston engines, and almost all liquid-cooled aircraft engines of the World War II period used this solution. Absolutely, and our products are not just for cars. Any vehicle with a cooling system can be susceptible to leaks. So, whether it’s a small car, large car, an SUV, 4×4, motorbike, van, or even static agricultural equipment, if it has a wet cooling system with a leak – pour in some Holts Radweld to get things running again. How does Radweld seal holes without causing clogging or damage?It is sometimes necessary for a car to be equipped with a second, or auxiliary, radiator to increase the cooling capacity, when the size of the original radiator cannot be increased. The second radiator is plumbed in series with the main radiator in the circuit. This was the case when the Audi 100 was first turbocharged creating the 200. These are not to be confused with intercoolers.

In fact, you don’t even have to find the leak – we’ve done the hard work, so you don’t have to. Just pour in Holts Radweld and go. How long will Radweld last? Engines for stationary plant are normally cooled by radiators in the same way as automobile engines. There are some unique differences, depending on the stationary plant – careful planning must be taken to ensure proper air flow across the radiator to ensure proper cooling. In some cases, evaporative cooling is used via a cooling tower. [8] See also [ edit ] Simply pour and fix, it couldn’t be easier. Radweld then works its way through the system to target radiator leaks without damaging or clogging the system. Radweld is designed to be added directly into the engine’s expansion tank. You don’t need to drain or flush the system before you use it – just pour and go. Radweld works through the radiator channels to seal leaks without any clogging or damaging effects, so all you need to do is pour it in and let it repair the leak. If you have identified the radiator valve to be the source of the leak and leaking water this could be due to the compression in the valve expanding due to the heat. This means you may only see the leak when the system is hot.

If I use Radweld will I have to replace my radiator later?

Since the development of aluminium or mixed-metal engines, corrosion inhibition has become even more important than antifreeze, and in all regions and seasons. Radweld is suitable for all cars and mixes with all types of coolant/antifreeze already in the cooling system. You don’t need any special preparation to use Radweld and there’s no need to drain or flush the cooling system. Opening a hot radiator drops the system pressure, which may cause it to boil and eject dangerously hot liquid and steam. Therefore, radiator caps often contain a mechanism that attempts to relieve the internal pressure before the cap can be fully opened. Radweld provides a permanent repair for small faults in the cooling system, including the hoses and radiator. It seals without damage or clogging and can be used in all cars and with any type of coolant/antifreeze.
