Hilux d4d 1kd ftv engine reliability in Pakistan

[pwuser167377689717]

I have read a lot about 1kd ftv piston cracking issus online. Is it also an issue in Pakistan hilux 2016/2017 as they are equipped with the same engine. ? Can these engines last more than 300000km?

1KD main issue was came into notice in its very earliest models. And that issue was for its injectors. Most probably from 1998-2003/4 models had that issue which was fixed in later models.

Apart from that, 1KD is known very good engine. Keeping all fluids on level is the key for its long life.

apart from engine oil, what other fluids need to be maintained properly?

Blinker fluid & Cache Fluid

seriously bro? this is my first 4x4 with 1kd ftv, bought at 175000km, running flawlessly but any information for keep it running like this for a long time will be really appreciated.

[harrissaeed89]

Well jokes aside....up keep of fuel filter with original is a must...that would keep your injectors running beyond 150K KMs and yeah these do last more than 300K but make sure your cooling systems is at its best including radiators and hoses...you can use Liqui Moly Diesel Purge or other quality additives once a season. Just keep the intervals a bit shorter, rather than following what owner manual suggests

[pwuser167377689717]

brother really appreciate your advice. diesel purge to be used in the fuel tank or in the fuel filter during oil change? and what oill should i use at 180k , 5w30 ?

[harrissaeed89]

Such additives are to be used in fuel tank, for engine I use Ceratec with new oil once an year....any quality oil is fine as long as engine is in good nick, im using Delo Gold 15w40. You can choose which ever suites your budget and intervals.

[pwuser167377689717]

thank you brother for the info. never knew such details.

[affanhaq94]

Pretty simple, read the owners manual.

Also,

Change your oil as per recommended interval. I consider Pak to be severe conditions, so I would adhere to that.

Transmission fluid should be inspected. Yours is most likely due if never done. Change with proper spec trans fluid and filter. Do not flush, drain and fill only.

Brake fluid every 2 years. Inspect power steering fluid if equipped.

Change air filters every 5-8k with high quality filter.

Diesel purge may be done if never done before. Did on our pajero once at it has a noticeably smoother idle and acceleration.

Check/replace fluid in diffs and transfer case.

Replace coolant as per manual.

Thank you ! really appreciate.
On owner's manual it is mentioned to replace, timing belt, drive belt and water pump at 150000km or ever 6 years. None of this has done yet. Can you recommend a workshop in Lahore(reliable and tested), who has all the genuine parts and will do all the fittings as per the instructed torque?

[affanhaq94]

If your vehicle is equipped with a timing belt, refer to the owners manual for correct interval. Mostly from what I've seen, range is 100-150k Kms. I would have a trustworthy mechanic give the vehicle a full inspection if you are not comfortable with it's current condition.

This way, any items that are worn or due for replacement can be caught at the right time. I highlight 'trustworthy'.

I have not had personal experience with him, however, I have heard good things about @syncview . He name is mentioned many times in these forums.

[pwuser167377689717]

I am satisfied with current situation, but drive belt at 180000km still not changed is giving me nightmares. I will get in touch with him.

[harrissaeed89]

Not a bad idea to change the timing belt with tensioners...also look out for the differentials, F&R along with transfer case...change the fluids for these components.

[pwuser167377689717]

I paid toyota for full inspection today. They changed the fluids, diff front back, 4x4 and transmission oil. But toyota mechanic visually inspected the timing belt and insisted it looks perfectly fine and no need to change it at least for a couple of months. As i was worried they insisted to not to worry about it as its perfectly fine, including the tensioner.
Do timing belts really can last 200000km?

[affanhaq94]

They 'can'. It is also possible it has been replaced if in excellent condition.

The belt is made to last the manufacturer recommended interval. However, there are situations where the belt service life may exceed this. But, does anyone know EXACTLY when a mechanical component will break or fail? Nope. We can only guestimate based on service history and visual inspection.

If this engine is an interference engine, the belt breaking will cause your engine to fail.

So, if the belt is in good condition for now, have it inspected again in the future to ensure there are no dry rot/cracks which will cause it to break. Or, see if anyone has any record of it being replaced. You can then use this record to plan the next belt replacement.

If it has never been replaced, replacing it in the near future may be in your best interest to ensure longevity and peace of mind.

[pwuser167377689717]

Thank you for your detailed response. I've already replaced the timing belt, bearing, and tensioner for peace of mind.I've also changed all the fluids, including transmission and differential. The truck runs and feels great.

However, I've read quite a bit about injector replacement for the 1KD engine, with recommendations to do so after 7 years or around 150-200k km. While I haven't experienced any issues—no misfires, knocking sounds, idle problems, or smoke—should I be concerned as its at 180k? Would it be wise to replace the injectors as a precaution, or should I wait until I notice signs like rough idle or smoke, considering how expensive the replacement can be?

[affanhaq94]

If I was in your shoes, and this is me personally, I would not replace them at this time of your truck has no issues.

I would just be watchful for signs of hard starting, terrible fuel economy, loss of power, smoke etc.

However, I'm not sure if the Hilux can show this, but an OBD2 scan tool which can read balance rates of the injectors can guide you if there are any worn out injectors.

Again, with only 180k I doubt they would need replacement unless someone ran REALLY dirty fuel or used bad quality diesel filters.

Enjoy your Hilux!

[pwuser167377689717]

Thank you brother for your opinion! I am also more inclined towards waiting till it shows any sign. But I will get OBD2 reader sometime in future to keep a check on those injector readings.

Hilux is certainly love, my first 4x4 way better experience than sedans

[pwuser166331039855]

I want to put a suggestion if you are convinced.
I know a person who has injector checking machine. His office is at Walton Road where DHA main boulevard meets ghazi road (near Ghora Chowk).
You can contact him & have your injectors check. If they are OK, then keep them running.
And if test results are not good, then you will know how many of them you need to replace.
