🪁 Do Aluminum Radiators Require Special Coolant

At last, the coolant made for BMW may or may not come pre-diluted. It enables you to dilute the coolant or antifreeze depending upon the environmental conditions. Does BMW need special coolant? Yes, all BMW vehicles need a special coolant or antifreeze. It is because such coolant tends to serve several useful functions in the vehicle. For example, Evans is a good coolant for high-performance builds, and works great with aluminum radiators because there are no electrolysis worries. But Mike does suggest using a single-pass radiator instead of a double-, or triple-pass unit. "Single-pass is better to enhance flow," he said. "Evans performs better with more flow. I think the answer is "any normal antifreeze solution will do". There's no special requirement that I know of when fitting aluminium radiators. 29 posts · Joined 2008. #1 · Apr 20, 2009. I just bought a summit direct fit aluminum radiator, part number SUM-380457 . The radiator shop just showed me that the standard 5/16 1/2 x 20 inverted flair tube fittings that screw into the new Summit radiator transmission cooler are too short. There is not enough thread material to allow the Typical Color: Orange. Dex-Cool, an OAT type, was developed in 1995 for GM cars. When owners mistakenly added green coolant to systems that contained Dex-Cool system, blockages frequently occurred. In other respects, Dex-Cool is an acceptable coolant but must never be mixed with other antifreeze types. That is, unless the coolant has special additives to protect aluminum parts from corrosion. Otherwise, the nitrite in the coolant can "eat" the aluminum in your engine. Since more modern engines are using aluminum parts, nitrite is becoming obsolete. 3. Phosphate. Phosphate is a fast-acting acid that protects some metals from corrosion. The fact is, older copper radiators are made up of (4) four different materials, not just copper. The copper tubes are bonded to the fin with solder (lead) and that has very poor conductive properties. The tanks are made of brass and the side channels are steel. An aluminum radiator is 100% aluminum and the tubes are much wider and closer Contaminated coolant increase the fluid acidity which wears down the aluminum until leaks start to appear. Collision. As a front-end part, radiators are often involved in collisions. Even if the initial impact does not damage the radiator, smaller leaks in the cooling system can be found afterwards which also warrants radiator replacement. The accepted pressure range for a car's radiator is between 75-100kPa (or 11-15psi) and with a mix of 33% coolant/antifreeze to water the boiling point is raised to 121-125-degrees C.
