D4 Turbos

[Celtoid]

Another thread about the LR owner manual being light on information in certain areas made me remember this point:

The manual really says nothing about the turbos on my D4 SE....cooling, heating etc.

This is the first turbo'ed vehicle I've owned but have friends with older 4WDs that either have timers or they just let idle for a while.

What's the story with the D4 3.0L TD?

Unless you're treating it like a racing car, just turn it off as a normal car.

Thanks Scott. Why is that, better design, better materials in the turbos?

[Scouse]

It's the case with all the turbo diesels that I know of.

Turbo timers are not required for regular driving in 99% of cases anyway - I wouldn't go as far to say that they have a **** factor but.....
In theory they might be useful if you stop driving suddenly after a hard freeway run but how often does that happen? Slowing down & driving normally for a few minutes would be all that's needed.

IM not familiar with the D4 turbos, but most turbos with water cooled turbos you dont need to have a turbo timer.
Turbos without the water cooling can burn the oil withing the turbo bearings if shut down without a cooldown period.

just drive it normally, unless you have glowing turbos its not needed to let it idle, oil this days are very very good, and the engine design are getting pretty good, i wouldnt worry,

just enjoy what a great car you have:D

The D4 is my third turbo car. All have had water cooled turbo's so no real need for idle down time.

However....

If I had been giving my XR6 Turbo a bit of a hiding then I would let it settle for 2 minutes before shutting down.

The Mini Cooper D and the D4 I just shut them down. Since the XR6 I have got into a habit of a steady run on the last few k's of most trips. This helps temps to settle as well.

Thanks all.

Turbo timers are illegal and will void your insurance policies as the argument goes your elaving the vehicle running wihtout being behind the wheel and it can jump into gear and crash into something or kill someone.

Just the normal driving slowly after any prolonged period of high speed operation is sufficient to cool the thing down to normal parameters if your worried about it just let it idle for 30 seconds before you switch it off when you stop somewhere.

...Turbo timers are illegal ......

I saw better than that ; someone who left her Prado D running (key in
ignition ) and locked the door with the spare , whilst at a Driver-tea-stop
in Tully.

Watercooled :o Nope!

Unless you've been flogging the arse out of it, just turn it off...
I usually pull up, put in park, handbrake, undo belt... Turn off...

If towing I idle down 30 seconds or longer on a hot day if working hard...

Other than that...

Same with me Tombie2.
Pull up, undo seatbelt etc, grab mobile phone and whatever else, then switch off.
Obviously longer if towing. Apart from towing, one of the worse things is sitting at 100Kph on a freeway for a period of time then switching off straight away.
With a little patience, you know that you are doing the right thing by your vehicle.
Unlike my wife who has a 3 Series BMW TD. She gets in it when it is cold and drives it like Peter Brock used too. Then on the return race trip on two wheels, turns it off before engaging 'Park'.
You can only tell them!

Yep couldn't agree more with the "you can only tell them"

Hi all

Does this info also apply to an 2005 TD5 Defender.
I have added a performance chip and I've been told to allow it to idle for at least a couple of minutes, especially after towing.

Thanks

Hi Mick, yes same applies, although some say that you are better off cruising home slowly in a 60Kph zone as opposed to idling the vehicle for a couple of minutes. Either way, you are allowing the turbo to cool down
