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.
BMWs have specific coolant requirements (nitrite and phosphate free) to prevent build-up and corrosion of aluminum components, so not just any off-the-shelf antifreeze will do. Does BMW require special coolant? Every vehicle manufacturer, including BMW has developed its own coolant or requires a exact coolant that is unique to definite years
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, Be Cool radiators are made with a quality grade aluminum and are 100 percent aluminum welded. We don't use epoxy on our radiators.". Furnace brazing is when a dissimilar material is used to join metal components. These materials can include copper, aluminum-silicon, silver, nickel, or a variety of materials.Improperly grounded electrical devices can cause electrolysis to occur. 5. If the condition is still present after the grounds have been checked, it may be necessary to add extra grounds to the heater core and engine. A hose clamp can be used to secure a 16 AWG stranded copper wire to the heater core inlet tube.
Performance aftermarket aluminum radiators offer efficient cooling and weight-savings over conventional designs. Engine specs, available space and radiator appearance must be considered before making a selection. eP2h4VE.
