Diesel engine health

[Xulfiqar]

your 1 wire sensor is for the gauge. for coolant use toyota LLC red or pink coolant, If you are a real dieselhead then find some BASF Glysantin 05 or mercedes benz genuine coolant.

so it means no coolant sensor and glow plug will take same time whether engine is hot or cold ?

and what do u say about caltex coolant ? i was thinking to get that in my car.

My 2C doesn't have the coolant sensor to control the glow, can I DIY it? or it needs an additional circuit?

Dear xulfiqar Sir
Can you elaborate the mixing of 2T oil (LOW ASH) with diesel fuel per refil to prevent injector failure in 1kd or 2kd engine.
Is it safe?
Or stick with expensive fuel treatment or injector cleaning products.
Many 4x4 fourm claims its safe n easily burn completly
Thanks in advance

with the new high pressure direct injection engines you dont need such - the 2 stroke lube is used to aid the lubricity of the current diesel fuel to be compatible with oldschool injection pumps like toyota 2C, 2L etc.

check the glow controller, pop it open and look for a pin marked as THW

@xulfiqar
Please suggest engine oil for diesel engine like 2c and td 27

[Xulfiqar]

oldschool caltex delo gold, mobil truck 15w40

[Dongskie]

check the glow controller, pop it open and look for a pin marked as THW

Then shall i connect the "THW" to the temperature sender?

[Xulfiqar]

yes - the THW pin gets the variable ground input from the coolant sensor.

@Xulfiqar : I am currently searching around for a decent Diesel SUV (Either Prado,Pajero or Vigo) but I do not know how to check the health of a diesel engine. Can you recommend a simple instant test to check if the diesel engine is in good health or not ? Something which can be performed when I go to inspect a vehicle as to be honest I do not trust the local road side "Ustads"

my corolla 2C has just clocked 80K mileage and i got the inspection package from Toyota Cantt Lahore. here is what they gave me. too expensive but still there are many things which i wont be getting done right now such as the tires replacement and timing belt and ac belts and all that bearing stuff with it as i think it shall be done at 100K. please suggest can i also delete anything else from this package. moreover specific to the nozzle service he is suggesting to replace the nozzles and adjust the tappets. should i allow him to do it or not? please advise thanks

[Xulfiqar]

firstly - toyota cannt needs to brush up on their language skills, nozzel? diesal tonic??

At this mileage the best practice is to replace the timing belt, tension rollers, both cam and crank seals and also water pump, retime correctly, replace valve seals too while adjusting tappet clearances - once cam is out the valve seals are a 20 minute job with a saddle type tool to press the valves. No need to open the head.

The very very fishy bit of this estimate is that they have not mentioned any parts cost in valve clearance adjustment, that means the tappet shims are "free of charge". - Not possible.

Ask them how would they go about setting the clearances, do they replace the shims? grind the shims?... While at it, ask them to call out their head diesel mechanic and ask him how he would go about setting the injection timing on the pump once a new belt is installed.

[absar59]

thanks alot sir. will surely ask the mechanic about the valve clearance adjustment method and injection timing. so you are suggesting that i replace the timing belt, timing bearing and all the other A/C and dynmo belts which he has mentioned ?? and will add the cam and crank seals in the replacement list alongwith the valve seals.

make sure you check the engine stone cold - it should start on first attempt after a normal glow time 5-6 seconds - about less than 1 second for the new toyota 1KD engines in tropical climate.

the engine should run smooth and sound, should not act silly or belch smoke either. If turbocharged drive it around and see if the turbo is building boost, if not then verify (if electronic) that the ECU is not in limp mode, check the liquids, engine oil, coolant etc for good condition. If you see something odd ask the owner - if you see that plain water is being used as coolant ask for how long. Most cases in diesels are doomed with such practice.

Ask if any repairs were carried out.

@xulfiqar, can't seem to send this PM for the past few days, so may I post it here:

Hello Xulfiqar,

Any comments on converting to automatic tranny on my 2C?

Will be expecting speed loss? more fuel consumption? I'm planning because I am beginning to hate manual gear during traffic lol

I was Offered a tranny and torque converter for only P8,000 or roughly $200.US

[Xulfiqar]

you will have higher fuel intake with automatic transmission and some performance loss also, not too bad workable and would be perfect for traffic jams too (install an additional transmission cooler just in case)

what model transmission are you being offered?

The additional work needed to get it working is

1 pressure control cable bracket on injection pump
2 starter to be wired through neutral safety switch
3 reverse lamp to be wired through integrated neutral safety switch.
4 flex plate mounting on crankshaft
5 removal of pilot bearing from crankshaft (if so equipped)

correct mounting bracket for transmission.

[Dongskie]

Thanks @xulfiqar,

I wasn't informed of the tranny model/code but I specifically mentioned that it has to be from and for a 2C.

I will go back to the surplus shop today for verification.

@xulfiqar,

Automatic transmission is an A42D,
