Tutup radiator dirancang khusus dengan pegas (\u003Ci data-path-to-node=\"8\" data-index-in-node=\"120\">spring\u003C/i>) yang berfungsi menjaga tekanan di dalam sistem. Saat suhu air radiator meningkat, tekanan pun naik. Tutup ini akan menahan tekanan tersebut hingga batas tertentu (biasanya tertera di bagian atas tutup, misalnya 0.9, 1.1, atau 1.3 bar). Tekanan yang terjaga ini penting untuk menaikkan titik didih air radiator agar tidak cepat menguap.\u003C/p>\n\u003Ch3 data-path-to-node=\"9\">\u003Cb data-path-to-node=\"9\" data-index-in-node=\"0\">2. Mengatur Sirkulasi ke Tabung Cadangan (Reservoir)\u003C/b>\u003C/h3>\n\u003Cp data-path-to-node=\"10\">Jika tekanan di dalam radiator sudah melebihi batas kekuatan pegas tutup radiator, katup tekanan (\u003Ci data-path-to-node=\"10\" data-index-in-node=\"98\">pressure valve\u003C/i>) akan terbuka. Hal ini membiarkan sebagian air pendingin yang panas mengalir menuju tabung \u003Ci data-path-to-node=\"10\" data-index-in-node=\"204\">reservoir\u003C/i>. Tanpa mekanisme ini, tekanan berlebih bisa menyebabkan selang radiator pecah atau radiator retak.\u003C/p>\n\u003Ch3 data-path-to-node=\"11\">\u003Cb data-path-to-node=\"11\" data-index-in-node=\"0\">3. Mengatasi Efek Vakum (Vacuum Relief Valve)\u003C/b>\u003C/h3>\n\u003Cp data-path-to-node=\"12\">Saat mesin dimatikan dan suhu mulai dingin, volume air di dalam radiator akan menyusut, menciptakan kondisi vakum. Di sinilah katup vakum pada tutup radiator bekerja. Ia akan terbuka untuk mengisap kembali air dari tabung \u003Ci data-path-to-node=\"12\" data-index-in-node=\"222\">reservoir\u003C/i> masuk ke dalam radiator. Jika katup ini rusak, selang radiator bisa mengempis (terisap ke dalam) dan sirkulasi air akan terganggu.\u003C/p>\n\u003Ch2 data-path-to-node=\"14\">\u003Cb data-path-to-node=\"14\" data-index-in-node=\"0\">Mengapa Tutup Radiator Saja Tidak Cukup? Peran Vital Cairan Pendingin\u003C/b>\u003C/h2>\n\u003Cp data-path-to-node=\"15\">Tutup radiator yang sehat tidak akan bekerja maksimal jika cairan di dalamnya berkualitas buruk. Penggunaan air mineral atau air keran sangat tidak disarankan karena mengandung mineral yang memicu karat dan kerak, serta memiliki titik didih yang rendah (100′ C). Untuk perlindungan total, penggunaan \u003Cb data-path-to-node=\"16\" data-index-in-node=\"37\">Prestone Radiator Coolant\u003C/b> adalah rekomendasi utama bagi para pemilik kendaraan yang menginginkan durabilitas mesin jangka panjang.\u003C/p>\n\u003Ch3 data-path-to-node=\"17\">\u003Cb data-path-to-node=\"17\" data-index-in-node=\"0\">Kenapa Harus Pakai Prestone?\u003C/b>\u003C/h3>\n\u003Cp data-path-to-node=\"18\">Prestone telah lama menjadi standar emas dalam teknologi cairan pendingin otomotif.
