TOYOTA EMINA Overheating

[Renault Manto]

As adviced, I'd like to seek the help of those who had an experience with Emina Overheating. Any solutions?

I did the following:
a. Replacement of Cylinder Head Gasket
b. Re-phase of heads
c. Replaced Water Pump
d. Overhauled Radiator

Please advice dudes

Also, I heard of a shop in Araneta that specializes in this sort of vehicles. Please advice.

Many thanks!

ung pag-overhaul mo ng radiator, upper lang ba or general (up and down)?or just replace it with a bigger one, if possible...

ung aux fan ba sure ka bang gumagana lahat at full efficiency? from the other thread, i bet yours is a 3c-t (2.2L-t, 100ps*4200, 22kg-m(215N-m*2600), right? electronic controlled alam ko pag sa emina, meaning, may computer box yan, just like my liteace...check mo ung temp. sending unit, may be faulty....mukhang ganun ung sa akin,e...

electronic fuel injection ba?-->no more mechanical fuel pump?, curious lang ako,e...

a/t ba? baka dragging/sliding a/t mo...sumusuka parin ba ng tubig? baka malambot ung radiator cap mo din,e...ko hanap nga ko ng 1.1kg-m rated na cap...ung 0.9kg-m medyo malambot kasi natutulak pain ng pressure,e..

nagawa mo na kasi din lahat...invite kita sa yahoo group ko: http://autos.groups.yahoo.com/group/KAPE_Pinas/

Thanks dude! Anywho, top part of the radiator lang overhauled. I think we'll have a hard time finding the same size and thickness if I should replace it.

On the computer box, I really cant find anyone who can check it fully (and at the same time read japanese )

On the fuel pump, i'll have someone check.. let me get back to you on that one.

Yes A/T sya but not dragging, right speed for an automatic (and very nice RIDE at that).

On the Rad cap, I tried replacing it but still the same.

I'm sure someone has the ultimate solution to this.

I've been a SUV Diesel fanatic since 7 years ago.

My first vehicle was a Pajero '89 and learned the ropes from my first "wolf" (named him that). BTW, those who want chop chop accesories for this box-type model, Mang Orly's the man (Sampaloc)!

Then I had the Pajero '95 about 2 years back. Had a great time with that, never had a major problem. I just replaced all the tires and one door handle.

But I had to make a choice between function or fashion (in the male sense) for my wife was about to give birth to my 2nd baby.

We scouted for cars like Largo (not much leg room for the driver), Local Terrano (to compact), and around 3 EMINAs.

Apart from the overheating issue, I still believe that EMINA was a good buy. Spacious that the Paj series, much like the starex but cooler in shape.

Anywho, I just wanted to share with you guys. Thanks!

The solution, don't run it at over 100kph on extended period, better yet run it at 80kph all day and you will have no overheating problem. This is a fact, the 2LT heads will not stand prolong turbo boost. Talking about Japanese engineering!!!??? All 2LT has this problem.

And oh yes, replace the steel head gasket with asbestos based copper gasket(custom made in Evangelista, hehe). It seals better. I am not joking, it what I have in my 2LT Surf.

If this does not work, I have one more solution. Replace the thermostat housing so you can relocate the rdiator cap. If you will inspect the mating surfce of the cap to the aluminum water neck, you will see that the water neck is corroded. So water does not transfer to the water recovery tank, but spills around the water neck. Di ba panay kulay kalawang ang water neck. I have been there and I found the solution. Do not replace the cap with higher pressure, it will compound your troubles.

It happened to my Surf.

TURBO dude!!! Thank you so much! I'll have my mechanic check it out dude!

On the MPH, I do run at an estimate of 80 to 100 kph. But pag traffic, shoot!

And when I travel to Lipa, I have to be sure that it'll be safe again.

Thanks dude, i'll keep you posted!

[turbo]

The overheating is not caused be the traffic.

Overheating occurs after extended 100kph run. The cause is turbo pressure is seeping into the water jacket. When you resurfaced the head, you might have aggrevated the problem. So I opted for the softer but thicker asbestos-copper gasket. I have it for 3 years.

Also check the mating surface of the radiator cap and the water neck. This is the weakest point of the cooling system.

Check out the conversion that I did for the Surf. You are welcome here!

I'll do that dude, thanks a lot!

yan ang prob ko! pag extended lang run, susuka ng water....gawin ko nga yan..hope meron ng asbestos na yan for my 2c-t engine...papalitan ko nga din ng labi..pero kasi mukha pang ok,e...pero before, ung tubig pwede mo mapagkamalang coffee w/ creamer....aside nga pala sa radiator flush, anu pang pwede panlinis ko aside sa radiator flush..genreral overhauled na ung radiators ko, new pump and belts)..ung naipong kalawang nalang sa makina pinaproblem ko..is there another way aside sa pag-top overhaul...

nga pala, i noticed na may water line din going to the turbo compressor, anu po purpose non aside sa helps cool the turbo...ung 4d56t ng delica ko noon wala ganun...

so is it ok na di na masyadong matagal ang cool-time ko before patayin ang makina?

[turbo]

Water cooled and bearings ng turbo ng 2lt kaya wag mo tanggalin.

Ordinary water lang lagay ko.

Basta don't go over 80kph and you will be fine. Kahit dalin mo sa baguio.

[alwayz_yummy]

naka back-and-forth na ko baguio * 60kph..at masyado ko worry kung sumuka ng tubig,e...pagkasuka, hinto, lagay tubig...pero nung inuwi ko ng palayan noong sumuka, di ko hininto, direcho lang...

sir turbo, ano po permanent solution po dito, para pwede ko maihataw ng 80 something sa NLEX......

kapag lagi na ang overheat, damage na ang head or head gasket.

Pero ang una mong gawing, palitan ang thermostat housing. Yon kasing aluminum lip may corrosion na kaya doon dumadaan ang tubig pag-expand nito, instead sa overflow thank.

Pag di nakuha ng pagpalit sa thermostat housing, dun kailangan mo nang pabuksan ang head. Dpat pa leak test mo for cracks. Pasadya ka ng head gasket sa Evangelista kapalit ng bakal na gasket.

Kung gsto mo makita ang ginawa ko, pasyal ka lang dito.

now kasi, eversince nakauwi me from cabanatuan, di siya nag-overheat, nagsuka lang sa tank...then di na nadagdagan ung nasuka,e...i suspect na sobrang tubig sa system un... replace ko na din ung sending unit na nakikita ko..putol na kasi ung wire and kapal ng kalawang,e...

pero, eto napansin ko lang, di ko pa kinakabit ung wire ng sending unit, noong pinatakbo ko ung makina, gumalaw ung temp guage ko....so i suspect may isa pang sending unit....pero where? alam nyo po san posibleng nakalagay un?

nga pala, where nga pala area mo? culiat near proj. 6 ako,e...

layo pala...well, baka may time

sir manto, sorry sa pagsalvage ng thread mo ha? God Bless!

No need for apologies dude. Learning a lot from you guys . Added comment, a mechanic mentioned that "Probably" bingkong (? anu yung mechanic jargon na yun?) and mga heads ko. Which probably means I have to replace them, right?

Dudes, any idea where I can find a reliable surplus of the said vehicle? How much kaya?

[alwayz_yummy]

pagka ganun, it means you the head needs resurfacing...much worst kung bagsak sa crack test...palit ka na ng head...im hoping na di ganon ung van ko..kung di, no choice, hanap ng head or 3c-t to go!

or kung nagpalit ng head, i-papa-port and polish ko na ung head, then i'll use oversized piston rings/ pistons.....

Sir, Yummy,

Lapit ka lang pala sa akin. taga culiat poj. 6 ka pala, ako dito lang sa may congressional ave. cor mindanao ave. sa likod ng KFC. If u have time meet tau para makita ko din yung emina mo. Regarding sa overheating wala me ma aadvise kasi gas yung engine ko 2tzfe same engine ng local previa, never pa nag overheat yung emina ko. Ang ginawa ko drain ko lahat ng tubig ng bagong bili ko then pinalitan ko ng Absolute distilled water and coolant. Distilled ginamit ko kasi para maiwasan yung build up ng minerals sa radiator.

[alwayz_yummy]

sir dbulido, lite-ace po ride ko....yup kita-kitz lang...before luch ko lumalabas, sa TS-market/cherry/circle c......

gusto ko sana ng emina/estima/lucida basta 3c-te, awd and full canopy...kasi maluwag sa loob, comparable sa space ng spacegear..pero 1 big prob kaya di ko kumuha ng ganun bilang kapalit ng delica ko: misis ko...

di daw nya type ung itsura,e......kaysa pagawayan pa namin, liteace nalang, as seen sa sig ko...di kasi kaya ng selling price ng delica ko ung price ng hi-ace 2.8/3.0L awd supercustom limited...sayang at swak sa price ng delica ko ung estima,e...

kasi by experience, much hotter ang diesel engine than a gasoline...kasi un ang nagpapaignite sa diesel,e...

TURBO Dude, about the Evanghelista made gasket.. any particular shop/person to look for? And how much kaya dude?

About replacing the thermostat housing.. where can I best find one.. Evang or Banawe? So do you mean dude, papalitan ko yung water neck? Pasensya na dudes.. medyo ignarante pa ng konti.

I do appreciate the fact that i'm talking to the PROs.
