Lately, may narinig akong ginagawa sa radiator cap ng mx natin, half close lang daw para makahinga daw...

sa mga gumagawa neto, please take time to read this article...

"The car’s radiator acts as a heat exchanger, transferring excess heat from the engine’s coolant fluid into the air. The radiator is composed of tubes that carry the coolant fluid, a protective cap that’s actually a pressure valve and a tank on each side to catch the coolant fluid overflow. In addition, the tubes carrying the coolant fluid usually contain a turbulator, which agitates the fluid inside. This way, the coolant fluid is mixed together, cooling all the fluid evenly, and not just cooling the fluid that touches the sides of the tubes. By creating turbulence inside the tubes, the fluid can be used more effectively.

When coolant fluid overheats, it expands, causing the fluid to become highly pressurized. When it enters the radiator, the pressure increases even more because it’s in an enclosed space. The radiator cap acts as a release valve set to open at the maximum pressure point. Usually this is set at a density of 15 pounds per square inch (psi). When the fluid pressure inside the radiator exceeds 15 psi, it forces the valve open, allowing heat to escape and excess coolant fluid to overflow into the tanks on either side of the radiator. Once the radiator cools down, the coolant fluid in the overflow tanks gets sucked back into the pump, continuing its route through the cooling system.

Cars with automatic transmissions cool transmission fluid in the same way with a separate heat-exchange circuit built into the radiator. This two-step process of cooling the transmission fluid is equivalent to a radiator within a radiator. As the heated transmission fluid enters the transmission cooler, the oil’s heat is exchanged with the coolant fluid in the radiator, making the transmission fluid cooler while heating the coolant fluid instead. Then the coolant fluid’s heat is transferred to air in the radiator itself."

  • same logic sa singaw na head gasket, magtatapon lang ng coolant sa reservoir.. pag cooldown, instead na higupin nya ung coolant, hangin na lang hihigupin nya pabalik galing sa singaw..

    bow!!

  • Iba ka talaga sir Laybu!

  • (y) tnx sir loybu for this.....

  • madami ako gusto ishare dito, madaming tumataas ang kilay kasi, di naman kasi ako mekaniko at lalong hindi ako racer..

    parang sa radyo lang, AMATEUR...

  • Atleast nakakatulong ng walang bayad! tama ba paps? yaan mo sila

  • hahaha.....ang mabigat dun sir loybu mahilig ka magbasa at mag research.....malaking tulong yang sa mga newbie at sa mga nahihiyang magtanong...bout sa hemex natin....maganda din magbasa basa muna para me idea ka kung pano gagawin...keep it sharing sir :))

  • mukang kilala q cnsbi ni ser loybu ='P

  • physics 101 boyles law yata yun presure is directly proportional to temperature.. pag mataas po ang pressure kahit morethan 100 deg celcius na temp ng tubig sa radiator hindi cya kululo.. yun ang main reason kaya may cap ang radiator.. water pump po ang nag pa circulate ng tubig sa radiator..

    pag open sa atmosphere ang radiator hindi tataas ang pressure pag dumating ng 100deg ang temp ng tubig sa radiator mag boil na yung water.. pag nag boil yung water mag kakaroon ng build up ng minerals sa loob ng radiator kagaya ng nasa takure or thermos natin sa bahay yun yung mag cacause ng bara / clog sa radiator..

  • Lol! Yung may singaw nga lang sa hose masama na dahil magkakaroon na ng hangin sa loob ng radiator line, at ang hangin sa loob ng liquid cooling system means more chances na mag overheat ang makina. Mag evaporate din yung tubig kapag bukas yun.

  • salamat boss loybu sa info
