Fenomena ini membuktikan bahwa air, dalam kondisi tertentu, bisa menjadi jauh lebih destruktif daripada hantaman benda keras. Kavitasi bukan sekadar gelembung udara biasa; ia adalah serangkaian ledakan mikro yang sanggup melubangi bilah pompa berbahan besi atau aluminium hingga menyerupai permukaan bulan yang bopeng.\u003C/p>\n\u003Ch3 data-path-to-node=\"3\">Bagaimana Gelembung Kecil Bisa Melubangi Besi?\u003C/h3>\n\u003Cp data-path-to-node=\"4\">Secara ilmiah, kavitasi terjadi ketika tekanan cairan turun di bawah tekanan uapnya, menyebabkan cairan tersebut mendidih secara mendadak pada suhu ruang dan membentuk gelembung uap.\u003C/p>\n\u003Cp data-path-to-node=\"5\">Proses kehancurannya terjadi dalam sepersekian detik melalui tahapan berikut:\u003C/p>\n\u003Col start=\"1\" data-path-to-node=\"6\">\n\u003Cli>\n\u003Cp data-path-to-node=\"6,0,0\">\u003Cb data-path-to-node=\"6,0,0\" data-index-in-node=\"0\">Pembentukan Gelembung:\u003C/b> Saat pompa radiator bekerja, bilah kipas (\u003Ci data-path-to-node=\"6,0,0\" data-index-in-node=\"65\">impeller\u003C/i>) berputar dengan kecepatan tinggi. Di area tertentu, tekanan air turun drastis. Hal ini memicu munculnya jutaan gelembung uap mikroskopis.\u003C/p>\n\u003C/li>\n\u003Cli>\n\u003Cp data-path-to-node=\"6,1,0\">\u003Cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\">Ledakan ke Dalam (Implosi):\u003C/b> Ketika gelembung-gelembung ini berpindah ke area bertekanan lebih tinggi di dalam rumah pompa, mereka tidak pecah ke luar, melainkan \u003Cb data-path-to-node=\"6,1,0\" data-index-in-node=\"161\">meledak ke dalam (implode)\u003C/b>.\u003C/p>\n\u003C/li>\n\u003Cli>\n\u003Cp data-path-to-node=\"6,2,0\">\u003Cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\">Micro-Jet Berkecepatan Tinggi:\u003C/b> Ledakan ini menciptakan gelombang kejut dan \u003Ci data-path-to-node=\"6,2,0\" data-index-in-node=\"75\">micro-jet\u003C/i> (pancaran cairan super cepat) yang menghantam permukaan logam.\u003C/p>\n\u003C/li>\n\u003Cli>\n\u003Cp data-path-to-node=\"6,3,0\">\u003Cb data-path-to-node=\"6,3,0\" data-index-in-node=\"0\">Erosi Mekanis:\u003C/b> Meski skalanya mikroskopis, hantaman ini terjadi ribuan kali per detik di titik yang sama. Tekanan yang dihasilkan bisa mencapai ribuan PSI, cukup kuat untuk merobek molekul logam, menciptakan lubang-lubang kecil (\u003Ci data-path-to-node=\"6,3,0\" data-index-in-node=\"229\">pitting\u003C/i>), dan akhirnya mematahkan bilah pompa.\u003C/p>\n\u003C/li>\n\u003C/ol>\n\u003Ch3 data-path-to-node=\"8\">Ancaman Nyata pada Pompa Air Radiator\u003C/h3>\n\u003Cp data-path-to-node=\"9\">Pompa air adalah jantung dari sistem pendingin kendaraan. Jika kavitasi dibiarkan, efisiensi pendinginan akan menurun drastis. Bilah pompa yang terkikis (korosi kavitasi) tidak lagi mampu mensirkulasikan cairan pendingin dengan maksimal. Akibatnya, mesin mengalami \u003Ci data-path-to-node=\"10\" data-index-in-node=\"138\">overheat\u003C/i>, yang jika berlanjut bisa menyebabkan blok mesin melengkung atau turun mesin total. Masalahnya, kavitasi seringkali tidak terdeteksi oleh suara mesin biasa hingga kerusakan parah sudah terjadi.\u003C/p>\n\u003Ch3 data-path-to-node=\"12\">Peran Vital Coolant: Bukan Sekadar Air Biasa\u003C/h3>\n\u003Cp data-path-to-node=\"13\">Banyak pemilik kendaraan membuat kesalahan fatal dengan hanya menggunakan air keran atau air mineral sebagai pengisi radiator. Air murni memiliki titik didih yang rendah dan tidak memiliki zat aditif untuk mengontrol tegangan permukaan, sehingga sangat rentan terhadap kavitasi.\u003C/p>\n\u003Cp data-path-to-node=\"14\">Di sinilah peran penting cairan pendingin (\u003Ci data-path-to-node=\"14\" data-index-in-node=\"43\">coolant\u003C/i>) yang berkualitas. \u003Ci data-path-to-node=\"14\" data-index-in-node=\"70\">Coolant\u003C/i> dirancang khusus untuk:\u003C/p>\n\u003Cul data-path-to-node=\"15\">\n\u003Cli>\n\u003Cp data-path-to-node=\"15,0,0\">\u003Cb data-path-to-node=\"15,0,0\" data-index-in-node=\"0\">Meningkatkan Titik Didih:\u003C/b> Mencegah cairan berubah menjadi uap meski dalam tekanan tinggi.\u003C/p>\n\u003C/li>\n\u003Cli>\n\u003Cp data-path-to-node=\"15,1,0\">\u003Cb data-path-to-node=\"15,1,0\" data-index-in-node=\"0\">Aditif Anti-Kavitasi:\u003C/b> Membentuk lapisan pelindung molekuler pada permukaan logam untuk meredam hantaman gelombang kejut dari gelembung yang pecah.\u003C/p>\n\u003C/li>\n\u003C/ul>\n\u003Ch3 data-path-to-node=\"17\">Solusi Perlindungan Maksimal: Prestone dengan Cor-Guard™\u003C/h3>\n\u003Cp data-path-to-node=\"18\">Untuk memastikan pompa air dan sistem pendingin tetap awet dari ancaman kavitasi dan korosi, pemilihan \u003Ci data-path-to-node=\"18\" data-index-in-node=\"103\">coolant\u003C/i> tidak boleh sembarangan. \u003Cb data-path-to-node=\"18\" data-index-in-node=\"136\">Prestone Coolant dengan Teknologi Cor-Guard™\u003C/b> hadir sebagai standar perlindungan tertinggi.\u003C/p>\n\u003Cp data-path-to-node=\"19\">Teknologi \u003Cb data-path-to-node=\"19\" data-index-in-node=\"10\">Cor-Guard™\u003C/b> secara khusus dipatenkan untuk menghentikan kerusakan seketika.
