I roto i te tukanga mahi a te whakawhiti hiko, ka nui te wera ka puta, ka pā kino ki te mahi a te whakawhiti hiko. I te wā e whakahaerehia ana te whakawhiti hiko, ka nui te wera ka puta mai i te ngaronga o te takai me te matua, me whakawātea i te wā tika kia kore ai e pakaru te whakamarumaru i puta mai i te wera nui.

Ko te āhua whakamatao o te whakawhiti hiko e pā ana ki te momo hua whakawhiti hiko me te wāhi e whakamahia ana. Tuarua, ka whakaarohia ngā momo whakamatao rerekē i roto i te hoahoa me te whakarerekētanga o te kaha i roto i te awhe kāwai kotahi. Ko te mata anake o te tāke hinu ka taea te whakarite i te pāmahana o te taurite wera. Mā te pikinga o te kaha, ka taea te whakanui ake i te horahanga whakamahana i runga i te hanganga. Hei tauira, tāpirihia he paipa hinu me te pakitara tāke hei hanga hanganga kōpikopiko (tāke hinu kōpikopiko). Mēnā ka whakanuia te kaha, ka taea te pupuhi i te mata whakamatao. Mō te whakawhiti hiko he nui te kaha, kāore e taea e te tohanga kawe hiko taiao te tango i te wera i roto i te tinana whakawhiti hiko. Me whakamahi te papu hinu hei tuku i te hinu ki te ara hinu i roto i te koiri hei hanga i te tohanga kaha, ā, ka whakamahia te taputapu whakamatao he tino pai ki te tuku wera ki waho.

Ko ngā wāhanga whakamatao noa o te whakawhiti hiko he pouaka whakamatao, he radiator rānei. E rua ngā momo pouaka whakamatao: he pouaka whakamatao hau me he pouaka whakamatao wai. Ka whakamahia te aratau whakamatao wai i ngā wā motuhake anake, pērā i te puna wai rere e ranea ana, ā, ka whakaarohia te mahi ōhanga. Ko te radiator te tikanga e whakamahia ana i runga i te whakawhiti hiko kaha waenga me te iti, ā, e rua ngā hanganga: te hononga tika ki te tāke hinu me te hononga ki te tāke hinu mā te ipu hinu. Mai i te ara pumau, kei reira te hanganga wehewehe me te hanganga whakauru.

Mā te tāutanga, ka taea te wehewehe i te papa whakamahana kia rua: he mea pumau, he mea tango.

Momo PG: Pūmau, kāore he flange, tika tonu ki runga i te whakarewanga tāke wahie i roto i te whakawhiti hiko.

Momo PC: ka taea te tango, mā roto i te flange i runga i te tāke wahie kua whakapumautia ki roto i te whakawhiti.

Ka taea te wehewehe i te hanganga maramara o te radiator ki:

1) Momo whānui: He rite tonu te tawhiti o te pokapū o te wahi. Pērā i te PC1800-20/520
2) Momo kaki kūtai: Ka wehea te wahi ki te wahi roa me te wahi poto mai i te pokapū rerekē, ko te rerekētanga whānui o te roa me te poto he 300-500mm, ko te poto he 2 ki te 3. Pērā i te PC2700(2400)-26(2)/520.
3) Momo oko takirua: kei runga i te paipa kohikohi ko ngā hanganga oko takirua.

He maha ngā raina whakaputa o te awheawhe whakaputa whakawhiti hiko o tā mātou kamupene, pērā i te wetewete aunoa, te kutikuti poutū me te whakapae, te hanga hurihuri aunoa, te whakarewa ira-maha-ira kotahi, te whakarewa hononga, te whakarewa huihuinga, te whakakī waikawa me te whakapūtātanga, te horoi hinu wera, me ētahi atu, ā, he maha ngā whakatakotoranga o ngā hua pērā i te 310,460,480,520,536mm. Ka taea te whakamahi i te paninga kia rite ki te tono a te kaiwhakamahi mō te maimoatanga paturopi āhua radiator (peita paninga whakaoti, peita enamel ngako polymine waikawa kiriaku rānei) te peita wera rānei, ka mau tonu te tae o waho me te tāke torutoru o te whakawhiti hiko, he rite tonu te kanapa, he toi pai.

Ehara i te mea ko te whakamahana anake te mea e tukuna ana e tā mātou kamupene, engari ka taea hoki e rātou te whakarato i te panera o te whakamahana me te ngongo hinu. Ka taea e te kiritaki te whakarewa me te peita i tō rātou taha, kei a rātou te awheawhe peita me te whakarewa matua. Mā tēnei, ka taea e te kiritaki te penapena i te nui o ngā utu kawe.
