Thanks you sa reply sir DD. May isa pa ko tanong, sabi ng bayaw ko yung thermostat ng ck ko tinanggal yung valve, ibig sabihin free flowing na yung coolant na sabi nung mekaniko ok lng daw kase di na mag ooverheat. Napansin nya na hindi talaga tumataas temperature sa normal level. Question ko sir, ok lng ba yun ginawa ng mechanic? anung pros and cons kung sakali? Thanks again sir DD.
Btw, uuwi ako ng june para personal ko macheck yung pajero, dalhin ko jan sa inyo sa central diesel para through check and professional advice galing sa iyo.

Hindi okay tanggalin ang thermostat. Kung maayos ang thermostat at nagooverheat, may problema somewhere. Hindi tamang solusyon ito. Ang thermostat ay importante para mabilis na ma attain at mapanatili ang optimum operating temperature ng makina.

Ty sa reply sir. Hindi naman daw nag ooverheat, ayun sa mechanic para daw maiwasan overheat> Hindi rin pala tinanggal yung mismong thermostat, binutasan lng daw yung valve. Pansin ko nga puro remedyo ginawa ng mechanis sa ck ko, mahirap din kase wala ako sa pinas bayaw ko lng nag aasikaso. Ty sa info sir, first time ko kase mag diesel na sasakyan kaya nangangapa.

Mag o-overheat ang car pag tinanggal ang thermostat.

Sir dieseldude goodevening po.
Our car is a 2005 hyundai tucson crdi now at 70k kms. Last friday naputulan po kami ng timing belt. Pinalitan na po yung mga nasirang pyesa (4 intake cam followers at yung mga belt tsaka yung injector seals. Pinaltan narin yung air filter).
Today nagstart na po siya pero there is white smoke even at operating temp. Sabi po ng mechanic baka daw tinamaan din injectors. Ano po marerecommend niyo?

Sir Dieseldude,

Newbie here, I'm still back reading and I'm just at page 34. My Father died a month ago, he was the mechanic in our family, I don't know anything about cars, only in driving it. Due to his abrupt leaving, some problems with our Mitsubishi Adventure 99 model has remain unsolved. I hope you could give me some ideas so I could atleast get a better picture on what I am looking at before I go to a mechanic shop.

Hard starting even when engine is already hot. = already replaced glowplug
I have to atleast crank it 2 - 3 x before it starts.
Small white smoke coming out of the tail pipe when it starts, but none I can see when running
Battery was bought last Dec 2102, but I think it still is ok as it still can redondo the engine
Never overheated but almost once in 2010 the temp gauge has almost reach the H level, I immediately park it and let it cool down then add water to the radiator that has a leak. which had been repaired since. Now I am using coolant .
Ride is okay and still has "hatak power"
Mileage is at 180K kms.
Cleaned air filter with air compressor, filter was bought a year ago.
Already replaced fuel filter (OEM, followed your adviced).
Planning to have it change oil and replace oil filter by next month
I am going to try to add 2T oil in the fuel tank as an experiment, gotten from a thread on this site

I couldn't believe all the work and effort, pressure and cost my father has undergone in the maintenance of a vehicle

Thank you very much in advance

Check the glow plug relay. It will not energize your glow plugs if faulty.

Does white smoke deminish as engine reaches normal operating temp?

How much water did you have to add?

Mileage is at 180K kms. This is quite high.

Sir where can you find the glow plug relay?

White smoke disappear and is replaced by black smoke

About 3 liters sir

Update: Sir Dieseldude, it seems I have solved my hard starting problem. It seems that when I had replaced my fuel filter, I did not bleed the air out. A friend of mine help me with the bleeding and after that no hard starting. Now its one click and it starts. My problem now is I am seeing black smoke.

Hindi yan dapat maputulan ng timing belt at 70k kms. First owner ka ba?

Pinalitan na po yung mga nasirang pyesa (4 intake cam followers at yung mga belt tsaka yung injector seals. Pinaltan narin yung air filter).
Today nagstart na po siya pero there is white smoke even at operating temp. Sabi po ng mechanic baka daw tinamaan din injectors. Ano po marerecommend niyo?
1) Check timing
2) Pull down and test injectors.
3) Kung walang makitang problem, pull down cylinder head to check for bent valves.
