Lub cav yog lub hauv paus ntawm txhua lub tsheb. Internal combustion engine siv ntau yam mechanisms thiab systems. Txhua tus ntawm lawv muaj nws tus kheej txoj haujlwm thiab lub hom phiaj. Yog li, ib feem tseem ceeb ntawm lub cav yog qhov txias thiab lubrication system. Nyob rau hauv thawj rooj plaub, antifreeze yog siv, nyob rau hauv lub thib ob - roj. Cov kua dej no muaj lub hom phiaj sib txawv kiag li thiab muaj pes tsawg leeg. Nws yog qhov tsis lees paub tias lawv sib xyaw ua ke. Tab sis qee zaum teeb meem tshwm sim, thiab cov roj tau nkag mus rau hauv cov tshuaj tiv thaiv. Cov laj thawj rau qhov tshwm sim no yuav txawv. Cia wb mus saib qhov teeb meem no.

Key Features

Yog cov roj tau nkag mus rau hauv cov tshuaj tiv thaiv ntawm Chevrolet Cruze, qhov no tuaj yeem txiav txim siab los ntawm cov cim hauv qab no:

• Antifreeze qib. Nws yuav maj mam txo. Qhov no yuav tsum tsis txhob tshwm sim ntawm lub cav zoo. pheej poob qibqhia tias cov roj tau nkag mus rau hauv cov tshuaj tiv thaiv.
• Txuag xim. Thaum khiav ntawm qhov tsis ua haujlwm thiab qis qis, cov pa taws dawb yuav tawm ntawm cov yeeb nkab. Tsis txhob cuam tshuam qhov tshwm sim no nrog cov pa ib txwm tshwm sim ntawm txhua lub tsheb thaum lub caij ntuj no.
• Oil condition. Raws li nws sib tov nrog lub coolant, nws cov qauv hloov. Cov roj poob nws cov khoom, hloov xim thiab qauv. Outwardly, nws zoo li ib hom kas fes-xim emulsion. Tsis tas li ntawd, ib qho emulsion zoo sib xws yuav nyob ntawm cov roj filling cap.
• Lub xeev ntawm kev tiv thaiv kab mob. Roj tsis sib tov nrog nws. Yog li ntawd, cov yam ntxwv me me yuav pom meej meej ntawm qhov chaw. Qhov no zoo li cas hauv kev xyaum tuaj yeem pom hauv peb tsab xov xwm.

Yog tias cov roj tau nkag mus rau hauv cov tshuaj tiv thaiv kab mob hauv lub tsheb Opel, koj yuav tsum xyuam xim rau cov tswm ciab. Lawv yuav moist thaum twisted thiab muaj cov yam ntxwv tsw qab.

Vim li cas cov roj thiaj nkag mus rau hauv cov tshuaj tiv thaiv kab mob?

Cov laj thawj yuav muaj raws li hauv qab no:

• Lub tog raj kheej taub hau gasket puas. Qhov no yog qhov teeb meem tshaj plaws. Yog tias cov roj nkag mus rau hauv lub tshuab ua kom tsis muaj zog ntawm lub tshuab hluav taws xob, cov laj thawj kuj tseem nyob hauv gasket. Nws nyob nruab nrab ntawm lub taub hau thiab thaiv. Nws yog nws uas tiv thaiv kev sib xyaw ntawm ob lub kua nrog ib leeg. Tab sis dhau sij hawm, qhov gasket no tuaj yeem hlawv tawm. Cov qib antifreeze yuav poob, thiab cov roj stains yuav tshwm sim hauv lub tank nthuav dav.
• Deformation ntawm lub taub hau thaiv. Hauv qhov no, nws tsis ua rau tag nrho lub taub hau, tab sis tsuas yogib cheeb tsam ntawm nws. Vim li no, txawm tias tag nrho cov gasket yuav xau roj rau hauv lub coolant. Yog vim li cas banal - xoob haum.
• Kev puas tsuaj ntawm lub tog raj kheej thaiv. Qhov no yog qhov teeb meem loj tshaj plaws. Hauv qhov no, kev kho tsis tas yuav txuag tau. Qee zaum koj yuav tsum hloov tag nrho lub tog raj kheej thaiv. Tab sis qhov teeb meem no tsis tshua muaj tshwm sim.

Txhais tau

Peb tseem xav txog qhov ua rau thiab qhov tshwm sim ntawm cov roj hauv cov tshuaj tiv thaiv. Yog tias pom muaj teeb meem zoo li no, lub tsheb yuav tsis ua haujlwm ntxiv lawm. Qhov tseeb yog tias thaum cov roj tov nrog antifreeze, abrasive hais yog tsim. Lawv tuaj yeem ua rau lub cav puas thiab tsim cov cim scuff thiab khawb ntawm cov khoom tseem ceeb. Tsis tas li ntawd, qhov bandwidth ntawm cov channel raug txo. Raws li cov kua ua emulsified, txoj kab uas hla ntawm cov channel txo.

Yog, thiab cov khoom ntawm cov kua tau ploj lawm. Roj tsis zoo lubricate cov khub rubbing, thiab antifreeze tsis txias. Lub cev muaj zog overheats sai. Yog tias koj tseem siv lub cev muaj zog, nws yuav xav tau kev kho mob kim.

Kev kho mob

Yuav ua li cas yog cov roj nkag mus rau hauv cov tshuaj tiv thaiv kab mob? Muaj ntau txoj hauv kev los daws qhov teeb meem:

• Hloov lub gasket uas hlawv.
• Sib tsoo lub taub hau. Txawm li cas los xij, qhov no tsuas yog ua tau nyob rau hauv cov ntaub ntawv me me deformations. Yog hais tias lub tog raj kheej taub hau "led", koj tsuas yog yuav tsum hloov nws.
• Kho lossis hloov lub tog raj kheej thaiv.

Kawg ob txoj haujlwm ua-nws-koj tus kheejtsis txhob siv. Tab sis nrog kev hloov ntawm lub gasket, koj tuaj yeem ua nws tus kheej. Tab sis ntawm no, ib yam nkaus, ib tug yuav tsum to taub tias yuav muaj teeb meem. Tom qab tag nrho, koj yuav tsum tshem tawm lub taub hau ntawm lub block, raws li zoo raws li paub lub zawm torques. Yuav tsum tau ib lub torque wrench.

Ua-nws-koj tus kheej gasket hloov: cov cuab yeej

Txhawm rau ua qhov haujlwm no peb xav tau:

• Hexagon lossis me ntsis nrog adapter siv nrog lub ciaj ntswj.
• Slotted screwdriver.
• Torque wrench ntawm 10 txog 140 Nm.
• Pad tshem tawm.
• hnab looj tes tiv thaiv.
• Extension.

Kev npaj

Ua ntej pib qhov hloov pauv, koj yuav tsum ua ntau yam haujlwm:

• Tshem tawm cov cua lim vaj tsev.
• Txiav roj hoses thiab tag nrho cov xaim.
• Txhob tso quav qub txeeg qub teg.
• Unscrew lub pa manifold thiab tshem tawm cov high voltage nyob ntawm tej.

Yuav ua li cas ntxiv?

Tom qab ntawd, koj tuaj yeem nqa tus ciaj ntswj muaj zog nrog txoj hlua txuas ntxiv thiab hloov pauv cov bolts uas tuav lub taub hau mus rau qhov thaiv. Yog hais tias nws yog plaub lub tog raj kheej cav, feem ntau 10 bolts yog unscrewed.

Lub tog raj kheej taub hau yuav tsum tau nqa nruj nreem vertically. Tom ntej no, koj yuav tsum tau txais cov seem ntawm gasket. Nws tuaj yeem lo rau ntawm qhov thaiv lossis nyob ntawm lub taub hau. Koj yuav tsum tau soj ntsuam tom kawg rau xeb. Yog tias muaj corrosion, qhov no yog qhov cim tsis zoo. Lub taub hau yuav tsum tau milled thiab av.

Koj tuaj yeem tshem cov seem ntawm lub gasket nrog lub cuab yeej tshwj xeeb. Tab sis koj yuav tsum hnav hnab looj tes thaum ua hauj lwm nrog xws li chemistry. Qee zaumlub qub gasket tau yooj yim tshem tawm - tsuas yog rub nws ntug nrog lub hau ntswj. Tom ntej no, qhov saum npoo yog degreased. Nws yog ib qho tseem ceeb uas tsis muaj ib feem ntawm lub qub gasket nyob rau hauv nws. Tsuas yog nyob rau hauv xws li tej yam kev mob mus rau lub installation ntawm ib tug tshiab. Nws yog tsim nyog paub tias nws yog mounted nruj me ntsis raws li cov lus qhia. Lawv tuaj yeem pom ntawm cov ces kaum ntawm lub cav thaiv. Tom qab ntawd, mus rau lub installation ntawm lub tog raj kheej taub hau. Mount nws kuj nruj me ntsis vertically. Nws yog ib qho tseem ceeb kom tsis txhob dislodge lub gasket. Cov kauj ruam tom ntej yog kom ceev cov bolts. Qhov no yog ua nyob rau hauv ob peb theem. Yog hais tias peb coj mus rau hauv tus account lub motors ntawm pem hauv ntej-log tsav VAZs, ua ntej zawm lub bolts nrog ib tug quab yuam ntawm 25 Nm, ces 85, thiab ces 120. Tom qab ntawd, koj muaj peev xwm nruab rov qab tag nrho cov xaim, high-voltage nyob ntawm tej, hoses thiab. lub tsev lim cua.

tuaj yeem nruj rau lwm txoj hauv kev. Txoj kev no yog tsim rau cov neeg uas muaj lub torque ciaj ntswj ua haujlwm ntau dua 100 Nm. Txhawm rau ua qhov no, thawj zaug teeb tsa tus nqi rau 25 Nm, tom qab ntawd mus rau 85. Tom qab ntawd, peb twist txhua tus ntsia liaj qhov rooj 90 degrees. Nyob rau theem tom ntej, peb tig lawv dua los ntawm tib lub kaum sab xis.

Kuj tseem nco ntsoov tias tom qab thawj zaug pib, yuav tsum tsis muaj cov tshuaj tiv thaiv kab mob hauv lub taub hau-rau-thaiv qhov chaw docking. Yog hais tias lub coolant ntws tawm (qhov no tuaj yeem pom los ntawm nws cov yam ntxwv xim), ces qhov hloov tsis tau ua raws li kev siv tshuab. Ntxiv mus, xws li lub cev muaj zog yuav siv tsis tau. Koj yuav tau tshem lub taub hau thiab muab lwm gasket. Antifreeze feem ntau xau vim tsis raug lossis tsis sib xws bolt nruj. Yog li ntawd, nws tsim nyog ua tib zoo saib xyuas cov txheej txheem no.

Awdej nyab

Koj yuav tsum nkag siab tias tom qab hloov lub gasket, koj tsis tuaj yeem pib khiav lub tsheb tam sim ntawd. Tshem cov cua txias kom huv si. Nws yog ib qho tseem ceeb uas tsis muaj greasy me ntsis hauv. Txwv tsis pub, nws yuav cuam tshuam tsis zoo rau qhov txias ntxiv ntawm lub cev muaj zog. Yog tias cov roj tau nkag mus rau hauv cov tshuaj tiv thaiv kab mob, yuav ua li cas ntxuav lub cav txias? Txhawm rau ua qhov no, koj tuaj yeem siv:

• Citric acid. Qhov no yog txoj kev nrov. Rau kev ntxuav, koj yuav tsum tau ua ib qho kev daws. Noj 1 kg ntawm citric acid ib 10 liv dej. Yog tias cov pa phem tsis tseem ceeb, koj tuaj yeem txo qis rau 500 grams. Tom ntej no, ncuav cov tshuaj rau hauv lub system thiab pib lub cav. Nws yuav tsum ua haujlwm li 15 feeb. Tom qab ntawd lub cav raug kaw thiab tos 40 feeb kom txog thaum nws txias. Tom ntej no, npaj ib lub thawv nrog lub ntim uas tsim nyog (feem ntau tsawg kawg yog tsib litres) thiab ntws cov kua. Tom qab ntawd, dej huv (nyiam dua distilled) yog poured rau hauv thiab lub cev muaj zog yog ntxuav dua. Yog tias nws tau ntim nrog dej distilled, koj tuaj yeem siv tau ob peb hnub (qhov tseem ceeb yog tias nws tsis yog lub caij ntuj no). Tom qab ntawd, koj tuaj yeem sau cov tshuaj tua kab mob tshiab.
• tshuab ntxuav tais diav. Xws li cov khoom zoo kawg nkaus tshem tawm tsis yog tsuas yog edible rog, tab sis kuj cov kab ntawm cav roj. Yog li ntawd, ib txhia siv lawv rau qhov txias system. Ua li no, dilute lub xab npum nrog dej (tsis ntau tshaj 500 milliliters ib 10 liv dej) thiab ncuav rau hauv SOD. Lub cev muaj zog yog coj mus rau qhov kub thiab txias thiab cov kua yog drained. Tom qab ntawd cov dej huv yog nchuav thiab lub cav rov qhib dua. Cov txheej txheem rov ua dua kom txog thaum cov kua hloov nws cov qauv. Tab sis vim li cas ntau tus neeg tsis qhia siv txoj kev no?Qhov tseeb yog tias thaum tov nrog dej, cov tshuaj ntxuav tes ua npuas ncauj. lub cev muaj zog sai nce kub, nws muaj peev xwm inadvertently overheat. Yog lawm, thiab nws nyuaj rau tshem tawm cov tshuaj detergent.
• Specialized chemistry. Tias yog vim li cas cov masters pom zoo kom yuav cov khoom tshwj xeeb rau dej ntws, uas yog tsim tshwj xeeb rau lub cav tsheb. Lawv tsis ua npuas ncauj thiab qualitatively tshem tawm cov roj kab. Yuav siv chemistry li cas? Nws yuav tsum tau yaj nyob rau hauv dej huv raws li cov lus qhia (txhua lub chaw tsim tshuaj paus muaj nws tus kheej proportions) thiab ncuav rau hauv lub txias system. Lub cev muaj zog yog qhib rau 15 feeb. Tom qab ntawd lawv muffle, tos kom txog thaum nws txias, thiab ntws cov tshuaj. Yog tias cov kua muaj cov roj ntim loj, nws raug nquahu kom rov ua cov txheej txheem dua. Nrog xws li chemistry, koj tuaj yeem tsav tsheb rau ob peb hnub kom tau txais txiaj ntsig zoo tshaj plaws - tshuaj xyuas hais.

Thov nco ntsoov tias qee cov khoom tshwj xeeb tuaj yeem ua npuas dej. Yog li ntawd, raws sij hawm nws yog tsim nyog los xyuas lub expansion tank. Tsis tas li ntawd, thaum xaiv cov tshuaj tua kab mob, cov tshuaj orthophosphoric acid yuav tsum raug zam. Nws pib corrode seals thiab roj hmab kav.

Kev siv cov dej haus carbonated

Yog cov roj nkag mus rau hauv cov tshuaj tiv thaiv kab mob, qee cov neeg siv cov dej haus carbonated los yaug. Tab sis qhov no tsis tuaj yeem ua tiav, vim tias lawv muaj cov phosphoric acid uas ua rau cov kav dej. Yog li ntawd, koj yuav tsum tsis txhob siv dej qab zib rau cov dej yaug - tsuas yog tshwj xeeb chemistry.

Zoo kawg

Yog li, peb tau txiav txim siab vim li casqhov teeb meem no thiab yuav ua li cas yog tias cov roj nkag mus rau hauv cov tshuaj tiv thaiv. Puas muaj peev xwm tsav tsheb zoo li no? Cov kws tshaj lij muab cov lus teb tsis zoo. Kev ua haujlwm ntxiv ntawm lub tsheb no tsis tuaj yeem ua tsis tau, vim tias yuav tsis muaj qhov txias thiab lubrication ntawm lub cav.
