help re cool down of crdi diesel engine

[wiper]

Good am. I would like to ask if it is necessary to cool down the crdi diesel engine of innova diesel, hyundai tucson and the likes. I asked from hyundai regarding my concerned , they say its not necessary because of the intercooler but he speaks only for the hyundai but not sure of other brand. But with vgt crdi engine of carens and crdi of innova, may I ask if we should cool down the engine, if yes for how long.

I drive an Innova, it do have a turbo but no intercooler.

The SA said to cool down the engine between 2 to 5 mins.

The reason behind this is to release the build up pressure in the turbo itself after driving the car above 80 KPH... and during LONG drives.

And if you're city driving and haven't reach the speed 80 KPH and above, I guess it's safe to not cool down the engine.

BUT for me, city driving or long drive... I still follow what the SA advised.

it's not the engine that needs to be cooled, it's the turbocharger. particularly the oil in it.

you'd need to cool it down if you revved the engine hard during the trip.

you can opt to drive really gently (keep it under 2000 rpm) for the last 5-10 minutes of your trip instead of leaving it idle for 5 five minutes.

That or get a turbo timer, which automatically shuts down the engine after a set amount of time after you "turn off" the car.

This is what I do especially during long drives,- just keep the RPM at about 2K so that the turbo is not engaged, just before I stop for rest or fuel.

I also do this because I don't have a turbo timer or didn't have it set in my alarm. Fast highways are usually isolated from city streets, therefore, as soon as I leave the highway, I have to traverse some slow streets, and that is the time when I don't rev my engine too much to cool down my turbo.

sir having an intercooler does not mean that you dont need to cool down the turbo. the work of the intercooler is to cool the air from the turbo before entering the manifolds.

you need to idle the engine after running it because the turbo is still spinning and if you turn off the engine right away the oil supply is cut to the turbo. no oil supply plus a spinning turbo equals worn bearings. that is why idling it will make the turbo stop spinning. since it is powered by the exhaust gasses, during idle there is less exhaust gas force to spin the turbo.

that is why it is a wise investment to buy a turbo timer. yesterday we had a client who bought a turbo timer for his trooper. I asked why only now since his trooper is old already. he said he just replaced the turbo because it broke due to not having to idle it down when it was still new.

sir arb pwede ba malagyan ng TT yung mga cars with immobilizer? keys with chip not the alarm with starter cut off.

Sir what brands are your TT? Is the engine stop timer programmable?
Can you post your contact numbers?

[wiper]

can you check again, i think the innova have an intercooler. It is situated in the front like the radiator. thanks

[washburn]

nope wala pong intercooler innova
2.5 Liter Diesel, 4-Cylinder, In-line 16V, Double Overhead Camshaft (Turbo Charged) (2KD-FTV)

not like the fortuner
Direct Injection, 4-Cylinder In-Line, DOHC 16 Valve, Variable Nozzle Turbo with Intercooler (1KD-FTV)

Bro.,- I don't think that the Innova has a CRDI diesel engine...

pls correct me if i'm wrong but i thought the d4d is toyota's version of the crdi

[surg]

yup the D4D is toyota's CDRDI

Planning to buy a new Tucson CRDI. Kailangan pa ba warm-up and cool-down? How many minutes?

Sabi ng sales nila hindi na daw kailangan kasi bagong technology na. Not sure if true.

Last week nasa parking lot ako. May dumating na innova. Pagka hinto sa parking slot nag revolution ng makina ang driver tas shut off ang engine. Sa palagay nyo mga katsikot gaano katagal aabutan b4 magka problema ang turbo charger nya?

No need to warm it up. At first start in the morning, a few seconds is all it needs. After starting, count 1-10, smile to yourself on the rearview mirror, fasten your seatbelt, and go. Drive "sensibly" during the first couple of kilometers to help the engine attain normal operating temperature.

Depending on your driving habits, you can shut the engine off immediately if you're driving like a grandma all day. But if you drove it like you stole it, a few minutes of idling to cool the turbo is necessary, say 2-5 minutes.

I would always open the engine hood when I arrive home, if just to vent out residual heat after shutting down the engine.

okay na pala ung 2-5 minutes, thank you sa tip.

Given Manila traffic mahirap magharurot. Hahaha.
