Tikanga o te pūoko pāmahana wai:

Ko te pūoko pāmahana wai tetahi waahanga nui o te punaha whakahaere miihini motuka, ka taea te huri i te pāmahana hei tohu hiko me te tuku atu ki te waahanga whakahaere miihini motuka. Ka piki ake te wera o te wai, ka nui ake te wai, ka nui ake te kaha o te wera motuhake o te wai, ka nui ake te parenga o te pūoko pāmahana wai. Ko tenei huringa aukati ka kitea e te miihini whakahaere miihini, e whakahaere ana i nga tawhā penei i te werohanga wahie me te wa whakawera. I te wa ano, ka taea hoki e te sensor pāmahana wai te kite i te pāmahana o te antifreeze, ka awhina i te taraiwa ki te mohio ki te ahua mahi o te miihini me te mana mahi o te punaha whakamahana.
I roto i te poto, te kaupapa mahi o te pūoko pāmahana wai e hāngai ana i runga i te roha waiariki me ngā āhuatanga contraction matao o te wai. Ka piki ake te pāmahana o te wai, ka nui ake te parenga o te pūoko pāmahana wai, ka kitea te huringa ātete e te kōwae whakahaere pūkaha, na reira ka whakahaere i te āhua mahi o te pūkaha.
Ko te pūoko taumata wai i roto i te ipu ka tuku i te tohu taumata wai ki te kaiwhakahaere, ka whakatauritehia e te rorohiko i roto i te kaiwhakahaere te tohu taumata wai ine me te tohu kua whakaritea kia whiwhi i te ine, katahi ka tukuna nga tohutohu "tuwhera" me te "kati". ki te wai hiko hiko kia rite ki te ahua o te rereke hei whakarite kia eke te ipu ki te taumata wai kua whakaritea. I muri i te otinga o te mahi tango wai, ka tukuna e te rorohiko i roto i te waahanga whakahaere pāmahana he whakahau "tuwhera" ki te hiko hiko e whakarato ana i te reo wera, na reira ka timata te punaha ki te whakamahana i te wai i roto i te ipu. Hei whakarite i te pāmahana. I tukuna e te kaiwhakahaere te whakahau ki te kati i te paera, ka tapahia te puna wera, ka uru te punaha ki te ahua tiaki wera. I roto i te tukanga o te hōtaka, ki te whakarite kia kore e tae te punaha ki te taumata wai haumaru, kaore te kaiwhakahaere hiko o te puna wera mana e whakatuwhera i te paera, kia kore ai e mate te wera me nga aitua.
Ko te pāmahana wai me te pūoko taumata wai he mea tito he waahanga whakahaere pāmahana me tetahi waahanga whakahaere taumata wai, a ka rite ki te taputapu whakaheke i mua o te hiko hiko me te whakamahana muffler hurihuri mo te whakamahana. Ka utaina te pūoko pāmahana wai waka ki runga i te koti wai o te poraka pūkaha, te upoko rango ranei, ā, kei te whakapā tika atu ki te whakamatao ki te ine i te pāmahana whakamahana o te pūkaha. Ko te pūoko pāmahana e whakamahia ana i roto i te inemahana whakamatao he thermistor whakarea pāmahana kino (NTC), ka heke te ātete i te pikinga o te pāmahana, me te waea hono ki te ECU. Ko tetahi atu he waea whiti
