2005 Hilux Injectors

just read this thread very familiar subject in the local garage they dont have many fans aye

RE*11 you keep spouting the same thing . i told you last timeyou probably got dlc injectors
These injectors are NOT interchangeable as single replacements and must only be replaced by the same injector originally fitted. The DLC injectors can replace the original fitment injectors but ONLY as a full set of four. The ECU also requires a reflash to go with this injector change.
you hear about the software upgrade by toyota thats what they do. DLc injectors wont wear on ulsd fuel like the others .

DLc injectors wont wear on ulsd fuel like the others .

Really so i suppose then ya won't
NEED Flash Lube.
Aye!

in theory no but there is the other issue of ulsd diesel causing rust , i would still use a additive every now and then like that promar diesel additive to make sure no water makes it past the fuelfilter like it does in ulsd fuel by cross contermination of ethanol . thats what they think is what is causing the rust in ulsd Diesel on there studys. but with dlc injectorsyou wont nuke the engine no more . and the rest would be repairable not cheapalso to replace high pressure commonrail pumps but cheaper then whole engines. europe sells replacment cr pumps for 449 euro already in exchange for some diesel.

Some ULSD basics:

ULSD is hygroscopic, it actually holds more dissolved or suspended water (up to 2X as much) than Low Sulfur Diesel (Non-Road, Locomotive, Marine (NRLM), LSD, or S-500) or High Sulfur Diesel (HSD or S-5000).

This dissolved water causes several problems.

Toyota have their own CR diesel additive now, made in Japan, in a metal bottle.

For the old school diesel engines I am using Moreystreatement that supposedly has been developed over 10 years. Even the fabled old school hilux is likely to need a diesel additive if the owner does not wish to damage the seals and o rings in the diesel injector pumpby using the new diesel.

My old one has 530,000 kms on it still working as a couirier van not a drop of flashlube in it was serviced by toyota for the first 300ks never had a problem with it

Have heard a bit about the D4 model injectors needing replacing on this model. What are the signs that this needs doing or are they just done at x amount of kms !

if you run flashlube then you wont wear them out premature. a other issue was as far as i hear the heat -washers below the injectors and they needed a new ecu map , best to stay away from d4d crap and buy tdi vw amarok instead.

read that plenty morons on this forum with no clue . you need dlc injectors for low sulfure or they wear out fast especially on new commonrails flashlube would prevent the premature wear but has to be added each tank of diesel , Personally i would never in hell buy a D4 toyota

Is that why our work ute, yes a D4, has done 315,000km now with only one set of injectors seals and nothing else touched and it still runs perfectly, oh, and no snake oil additives either.

Ignore the above advice. The early 1KD motors require injector seat washer replacement every 45 000kms.

probably because it has dlc injectorsthey dont wear out and are made for ultra low sulfur diesel

Oh, and you'll know they need replacing when you first start the engine in the morning. There will be a bit of blue smoke, engine will run rough when cold, etc.

Note 2. The Euro IV spec engine has two different injectors depending on varying factors. The Euro IV engines ran with this injector between production dates 08/06 - 05/08 before changing to a DLC injector. These injectors are NOT interchangeable as single replacements and must only be replaced by the same injector originally fitted. The DLC injectors can replace the original fitment injectors but ONLY as a full set of four. The ECU also requires a reflash to go with this injector change.

this should be enough proof to what i posted above unless its got ulsd save injectorsyou will nuke them with low sulfur fuel and no additive, if its got dlc injectors then it be fine they are made for ulsd- ultra-low sulfur-diesel

Thanks for the info. I've had mine for just over a year and it's done 205000 with no smoke on start up and runs fine. I have no idea when/if injector seat washer or seals been done so would you recommend getting this done !

i would recommend finding out if it has the latest injectors if you can from service history. and take it from there.If you cant find out your best to use flashlube better save then sorry. Its expensive when these new commonrails nuke them selfs . if its got ulsd savedlc coated -injectors then your almost 100% save

my d4d 2,5 hiace had somewhere around 320,000kms, no snake oil, no dramas
