Antifreeze tawm mus, tsis muaj smudges - yuav ua li cas? Muaj kev daws!
Yog tias lub cim qis qis qis ntawm lub vaj huam sib luag pem hauv ntej teeb, cov dej xau tuaj yeem pom tau yooj yim nyob rau hauv feem ntau los ntawm dripping. Feem ntau, cov dej xau tau pom los ntawm lub tank nthuav dav nws tus kheej lossis los ntawm hauv qab nws lub hau. Yog tias cov hlwb ntawm lub tshuab hluav taws xob lossis lub qhov cub hluav taws xob puas lawm, ces koj yuav pom cov drips ntawm asphalt nyob rau hauv daim ntawv ntawm ntau xim. Cov kav dej feem ntau xau, tshwj xeeb tshaj yog nyob rau hauv cov kev sib tshuam. Lwm qhov teeb meem tshwm sim yog lub twj tso kua mis dej thiab lub ntsuas sov.
Txawm li cas los xij, feem ntau qhov xwm txheej tshwm sim thaum theem ntawm cov tshuaj tiv thaiv kab mob poob qis sai sai, thiab cov dej xau tsis tuaj yeem pom pom. Ntawm peb lub vev xaib Vodi.su, peb tau mob siab rau ntau cov ntawv rau kev tsim lub tshuab ua kom txias thiab xaiv cov tshuaj tiv thaiv kab mob, qhov uas peb tau hais tias yuav tsum tau hloov pauv ib zaug hauv ob xyoos. Tsis tas li ntawd, lawv tau tham txog yuav ua li cas ntxuav lub tshuab ua kom txias. Yog tias muaj qhov xau ntawm cov tshuaj tiv thaiv kim kim, thaum nws tsis tuaj yeem tshawb pom cov cim pom tseeb ntawm cov pa xau, tus neeg tsav tsheb txhawj xeeb xav tias qhov kev txhim kho txaus ntshai tshaj plaws ntawm cov xwm txheej - tshuaj tiv thaiv kab mob nkag mus rau hauv lub tog raj kheej.
Antifreeze mus rau hauv lub cav
Yog li ntawd, yog hais tias koj muaj xws li ib tug tsis txaus siab, ces feem ntau yuav ua rau yog ib tug hnav lub tog raj kheej thaiv gasket. Nco qab tias lub coolant circulates los ntawm tshwj xeeb raws thiab nyob rau hauv lub engine, yog li tswj ib tug zoo kev khiav hauj lwm kub nyob rau hauv lub cheeb tsam ntawm 90-100 degrees. Yog tias qhov kub nce siab tshaj qhov cim no, cov hlau yuav pib nthuav dav thiab cov pistons tsuas yog jam.
Lub tog raj kheej thaiv gasket yog siv los kaw thiab cais lub taub hau thaiv ntawm lub cav. Thaum lub sij hawm, nws hnav tawm, los yog thaum lub sij hawm kho nws raug ntsia nrog kev ua txhaum cai. Raws li, antifreeze los ntawm lub taub hau yuav maj mam ntws ncaj qha mus rau hauv lub tog raj kheej.
Peb teev cov yam ntxwv tseem ceeb:
- tuab cov pa luam yeeb dawb los ntawm cov yeeb nkab uas muaj ntxhiab tsw qab;
- ib tug ntse nce nyob rau hauv cov roj theem;
- Thaum kuaj xyuas qib nrog lub dipstick, peb pom tias cov roj tau hloov nws qhov sib xws thiab muaj cov npuas hauv nws.
Yog vim li cas antifreeze nkag mus rau hauv lub engine thiaj li txaus ntshai? Qhov tshaj plaws yog tias, vim nws sib xyaw nrog cov roj, nws poob nws cov khoom, ua kom qis dua thiab tau txais qhov tsis sib xws. Yog li ntawd, tag nrho cov conductive channel rau lub coolant yog clogged, feem, lub tshav kub pauv ntawm lub hwj chim unit raug kev txom nyem.
Dab tsi yog qhov kev hem thawj?
Qhov no hem:
- overheating ntawm lub cav;
- ceev hnav ntawm piston rings;
- ceev ceev ntawm tus pas txuas txuas thiab lub ntsiab bearings ntawm lub crankshaft;
- ceev noj ntawm antifreeze nws tus kheej.
Nyob rau hauv ib lo lus, txhua tus neeg tsav tsheb tsim nyog yuav tsum tau them sai sai rau lub sij hawm mus rau qhov poob ntawm antifreeze nyob rau hauv lub expansion tank. Tau kawg, koj tsis tas yuav saib hauv qab lub hood, txij li lub tank tau nruab nrog lub sensor uas teb rau kev hloov pauv ntawm cov kua hauv lub cev. Tsis tas li ntawd, qhov nce ntawm cov roj cav ntim thiab qhov poob ntawm nws lub siab yog lwm tus chij liab los ua kom tsis txhob muaj qhov xwm txheej no.
Vim li cas lwm tus tuaj yeem tiv thaiv kom tsis txhob muaj kab mob?
Ntawm chav kawm, lub zeem muag ntawm ib tug loj overhaul tsis yog lub feem ntau rosy expectation. Txawm li cas los xij, qee zaum koj tuaj yeem pom qhov poob qis hauv qib ntawm cov tshuaj tiv thaiv kab mob tsis muaj cov tsos mob tau piav qhia saum toj no. Lwm qhov twg tuaj yeem tiv thaiv tsis tau xau?
Raws li txoj cai, tej zaum yuav tsis muaj ntau qhov chaw ntawm nws cov leakage uas tsis tuaj yeem kuaj pom. Tus kheej, los ntawm kuv tus kheej kev paub, kuv yuav tsum tau ntsib teeb meem thaum ib qho ntawm cov hoses ua rau lub qhov cub hluav taws xob xau. Qhov tshaj plaws yog tias cov hoses no muaj kev tiv thaiv los ntawm cov khoom siv cua sov, uas cov tee me me yuav luag tsis pom. Tsis tas li ntawd, lawv nyob ncaj qha rau saum lub qhov tso pa tawm thiab tso pa tawm ntawm cov muffler, uas ua kom sov thaum lub sijhawm txav mus los.
Yog li, cov tee tsuas yog evaporated. Koj tuaj yeem tshawb xyuas qhov xau los ntawm tus yam ntxwv tsis hnov tsw, los yog ua tib zoo tshuaj xyuas tag nrho cov kav dej thiab cov nozzles los ntawm cov tshuaj tiv thaiv kab mob.
Kev tshem tawm ntawm kev tawg
Yog hais tias nws yog lub block gasket, ces koj yuav tsum tau hloov nws.
Txoj hauj lwm, cia peb hais tam sim ntawd, yog qhov nyuaj:
- khaws lub gasket nws tus kheej;
- mus rau qhov thaiv lub taub hau npog, tshem tawm txhua yam ntawm cov kav dej, sensors, cov lus qhia ntsaws ntsaws thiab cov xaim hluav taws xob siab, thiab lwm yam .;
- tshem lub sij hawm siv, thaum kho lub crankshaft pulley thiaj li tsis txhob yuam kev;
- unscrew 8 lossis 12 bolts ntawm lub hau npog thiab tshem tawm;
- ces unscrew lub taub hau nws tus kheej;
- tshem tawm cov qub gasket, ntxuav thiab degreasing saum npoo;
- tom qab hloov lub gasket, rov ua txhua yam hauv qhov kev txiav txim rov qab.
Ua tib zoo mloog rau ib qho taw tes - lub gasket tuaj yeem ua rau tsis muaj kev puas tsuaj, tab sis lub taub hau bolts tuaj yeem xoob nruj, uas, qhov tseeb, ua rau muaj dej ntws. Tsis tas li ntawd, tej zaum yuav muaj qhov tawg me me ntawm lub taub hau. Yog li, cov neeg ua haujlwm kho mob ntawm Vodi.su pom zoo hu rau cov chaw pabcuam tshwjxeeb, qhov twg txhua yam yuav ua tau zoo, sai thiab muaj kev lav phib xaub. Koj tseem tuaj yeem txuag lub sijhawm muaj txiaj ntsig.
Yog hais tias lub qhov cub hoses xau, ces koj yuav tsum nrhiav qhov chaw ntawm cov xau. Thiab qhov no tsis yog ib txwm yooj yim ua. Raws li, koj yuav tau hloov lub nozzle. Cov pob qij txha feem ntau xau, qhov twg clamps, ceev txuas lossis adapters ntawm nozzles thiab hoses raug teeb tsa.
