Tap water in the radiator? No way! SPEAK, PROFESSOR! • Tap water in the radiator? No way... O MECÂNICO RESPONDE is the section where we answer questions that come to the editorial staff of REVISTA O MECÂNICO. We send your questions to auto parts manufacturers, assemblers and our technical consultants and these are some of the answers that came to us. In this program, we address: 0:58 In cooling maintenance, few mechanics actually remove residual water from the block. Cleaning is usually done with tap water and then the radiator is just drained and whatever is left in the block is left. After all, it is more annoying to remove this water. Another thing: demineralized water is the correct option, there is no doubt about that, but in most of the tests on YouTube, from the most technical to the simplest, demineralized water oxidizes like any other. I'm not saying all of them, but in most cases, what really matters is the additive. 3:07 Even after filtering it twice (in a clay filter with activated carbon candles), can't this water still be used in the cooling system? 4:00 Many people have been using tap water with soluble oil in their car's radiator for years and it doesn't cause any problems. It's cheaper than those branded additives, it cools really well, doesn't corrode anything and doesn't dry out hoses and plastics. 5:16 Professor, I'd like to know what kind of damage I might run into by using the coolant additive in the Gol G4. The customer hasn't used the additive for 11 years. 6:18 When replacing the water pump, with the loss of coolant, is it necessary to replace all the coolant or just top it up?
