    I own a 1996 Mitsubishi L200. I had the IC of my alternator repaired twice coz pinasukan na ng oil.

    After i have the oil seals replace I will buy a new alternator. So ano magandang brand na replacement lang na alternator?

    if the cause of the alternator failure is the oil leaking into it, the most probable part inside that failed are the carbon brushes. just have it cleaned with electrical contact cleaner or mineral spirits, replace the brushes, bench test and reinstall

    pero kung talagang trip mo bumili: go surplus IMO. Valeo yung nabili kong surplus. had the brushes and oil seals changed before installing them. check mo rin yung mounting ears nung alternator kung ok pa ang roundness at yung distance ng mounting points. sukatin mo muna yung mounting arm sa front lower case-oil pump assembly.

    Yup bibili nalang ako ng bago. I saw your thread alternator diy and i find it very informative. 4d56 din yung engine mo. 75 amperes ba talaga sa 4d56? Bakit ba pinapasukan ng oil ang alternator? Thanks.

    BTW, may napansin lang ako kanina pauwi ako. Head light on and aircon on. Pag traffic at umaandar ang compressor medyo humihina ang ilaw and buga ng aircon. Pero pag nakapatay ang compressor lumalakas ang buga ng air con and ilaw. Ano kaya possible cause nito?

    rotor shaft (where the oil seal grips) could also be grooved. TS, refer to the thread Alternator DIY for some pointers para hindi ka maloko ng mechanic mo.

    You can also try going to Ace Hardware in SM Makati. They have a cataloque of replacement alternators for various vehicles. I bought one before there and it is still good after 4 years.

    Sirs, reviving thread. Kumusta na po yun alternators na nabili nyo? Any specific recommendation kung saan okay bumili ng reman or surplus alternator (aside from ace hardware)? Yun tipong garantisado ang binebenta. Need to change alternator na kasi (4d56 N/A).

    Thanks in advance.

    ^kelan pa ba yang battery mo? maybe nearing its expiration na. recheck mo rin v-belt tension (baka kulang sa tension)

    4d56 pero turbocharged yung akin. 75A ang stock specs sa mga 1st gen afaik (pati rin ata sa mga advies). you can always go higher like 90 A or 110 A without any change sa vehicle wiring. yan din mistake ko dapat higher amperage na rin yung kinuha ko nun.

    causes ay pwedeng hindi maganda ang seating ng oil seal, matigas na yung oil seal, maaari din may "canal" na yung shaft ng rotor kung saan nakakapit ang oil seal, or pwede ring alignment issues ng alternator.

    Mine is just a stock 4d56. pag 90 ampere pinili ko masmabilis ba uminit ang makina? L200 ko kase pag traffic umiinit lumalagpas sa half pero pag umandar na babalik sa half.

    Medyo bago pa battery ko 9 months old.

    ^sintomas ng walang thermostat yan. pacheck mo kung meron o tinanggal na. nasa water pump suction yung thermostat location nyan (lower hose). kung wala bili ka na lang sa mitsubishi wala pa P1k.

    surplus.. alternators have a very long service life..
    but what do you mean by alternator failure? it does not generate electricity, or the (oil-contaminated) pulley is slipping?
    but i am curious... san galing yung oil? and i thought the IC is water- and oil-proof. mebbe your alternator just needs a good cleaning and a new set of brushes..
    and i do not think alternators figure significantly in engine heat scenarios..
    and thermostats just make the engine reach optimum operating temperature, faster. an absent thermostat will not make the engine overheat. perhaps your heat problem can be traced to the radiator.

    sa may vacuum pump sa likuran lang ng alternator galing yung oil.

What's a good brand of replacement alternator?
