Overhaul?

[apsa]

mga sir,

magtatanong lang po regarding sa nissan caravan a/t na madalas mag over heat. It happened mga 2 months ago nung na-rent kami to tagaytay pero galing lang po kami ng Dasma Cavite siguro mga 30-mins to 1hr drive lang po ang layo.... nag 1st over heat sya kasi namatay yung fan nung 2nd radiator sa ilalim (i think yun po yung para sa aircon) kaya parang nagkaleak. Naitakbo pa rin namin pabalik ng dasma ng dahan dahan that time thouygh pag nahinto nag ooverflow yung reserve. After that parang humina po batak nung sasakyan and prang mejo mas malakas ang ingay nya na before sya mag over heat. And kahit mga Dasma to Kawit nag-oover flow pa rin yung reserve po for how many times na. Ano po kaya problema nun?

Need help po. Kc sabi ng isang mekaniko dapat daw kunin sa dukot, sabi nung pangalawang mekaniko wag daw ipadukot kc baka sayang pera sabi nya try muna palitan ng ATF kais po to be honest mga 2 years na since last magpalit ng ATF at amoy sunog na. Sabi nya baka kaya hirap makina kc hirap daw tumulong ang transmission.... pag di daw nakuha baka over haul daw po... ano po ba dapat talaga namin gawin.... ?

Ngayon po, pag naka start at i-open ang radiator cap di naman na-sirit ang tubig pero nagsi-circulate. napa overhaul na rin po namin both radiators.

ty po in advance....

before you decide of throwing your money away and before being sold to the notion that your engine needs "overhaul", consider the age of the car versus the expected expenses and more expenses if the "overhaul" is not done right. tests must be performed before deciding to have the engine undergo a major repair. how is the compression? how is the engine oil pressure? what was the engine vacuum when the engine is at idle speed? how does the specimen of the lube oil look like? how does the spark plug tips look like? where is the noise coming from, the top or the bottom? some people who need money will try to make you spend even if you don't need to. have a complete engine performance diagnosis done first.

sir thanks for the reply... nakalimutan ko po sabihin na diesel po ang makina and wala namang katok it's just that noticeable po talaga yung naging paghina ng batak... i mean nagka increase lang ng tunog pero noticeable din yung naging increase po sa sound nya before(pero wala pong katok sir).... and parang hirap po ang makina.... good thing we have this forum na tumutulong sa mga di ganun kagaling sa sasakyang tulad ko.... thanks sir very much appreciated, we could have just listen to any of those mechanics....

Looks like your cylinder head gasket needs replacement...top overhaul. My friend's diesel Revo experienced the same symptoms you are experiencing...overheating and mahina hatak. She eventually had the vehicle top overhauled and the problems vanished. Although your vehicle could have other problems, in my opinion its due for a top overhaul.

what is the mileage of the car? have you operated the engine without air filter before? did you change your fuel recently? the engine might be suffering from preignition caused by carbon build up. does your engine use a timing belt? if the problem was due to carbon build up, you don't need an overhaul. just have the combustion chambers decarbonized

First time kong naoverheat ng napudpod na ang clutch lining ko, pati clutch disk kinain. Mabagal ang takbo ko, 1st gear lang ang kaya tapos unti-unting tumaas ang temp hanggang umabot sa redline. Itinakbo ko pa ng mga 13 kms na sa 1st gear lang, umuusok (white smoke) na pala ang likuran ko na parang may sunog.

Sir i took the van yesterday to another yet reputable shop and the mechanics diagnosis is on the transmission. When we pulled out the dipstick of the transmission you could really notice that the ATF smells like burned oil already... it's been 2 years ago since i last changed it's ATF (my fault, it's muy first time to have an A/T ride po kasi).... he said if that won't work, then maybe it's time to replace my transmission. Because when he opened my radiator cap wala daw pong hangin na lumalabas naman or yung para pong humihigop.... and maganda pa raw talaga tuniog ng makina parang hirap lang sya umarangkada because hirap na tumulong yung transmission ko. Kaya mukhang hindi raw po sa cylinder head.


I also bought a new air filter because the mechanic also told me it needs replacement already. I just hope makuha sya sa changed oil ng ATF. If not, sir would you recommend any reliable surplus shop where to get a replacement sirs? And sirs, would you still advice me if i should get a M/T or another A/T to replace my old A/T if it is indeed not working already? huhuhu..... what a week!!!

Bro,

Mukhang dumadami ang problema ng kotse mo. Might I suggest na benta mo na lang yan, moneytrap na kasi yan. Bili ka na lang ng Nissan urvan na segunda mano na manual transmission or nissan urvan estate na segunda mano na lang. If I'm not mistaken converted/surplus ba yan bro (caravan mo) ?

Yes sir converted po surplus from subic. I got it 2 years ago pero from the person who bought it there na. after po we changed atf tumahimik makina mukhang hirap lang talaga because of my tranny sabi ng mekaniko po talang mukhang needs replacement na po kc kahit mejo tumahimik yung makina still hindi poa rin ganun kalakas ang batak. my fault po talaga yung makina ok pa po talaga...

Sir any recommended surplus shop of M/T tranny in cavite or kahit saan na reliable po talaga? palit na lang po ng M/T tranny...

1.) Any tips din po kung paano pumili ng maayos na M/T tranny? Though may kasama po ko malamang mekaniko when buying. This friday na po kami titingin...


Salamat po in advance mga sirs....

Kung surplus na transmission ang kukunin mo humingi ka ng warranty para hindi ka nagaalala kung masira agad o pagkinabit may diprensiya nakuha mo dahil surplus na ito.

[apsa]

ah okay po sir speed.... May warranty po pala yun... cge po i'll ask yung mga pupuntahan po naming shop and the mechanic po.... This would surely, save me more money.... thanks again....

[sigwaldp]

sir kamusta po yung conversion niyo ng automatic tranny to manual tranny? lumakas po ba ang hatak?
