Newbie Turbo question
 

Hi

Im a newbie to 4x4 and my Cherokee is my first 4x4. Its a 2.5 Litre and is
about 8 weeks old :). My concern is the turbo. The salesman said that as
long as i wasn't revving the engine before i turn off the engine the turbo
would not need idling time to cool down. The manual gives contrary advice,
it says the turbo should always be given cooling time quoting from '1min'
for easy load to '10min' for heavy load. Occasionally i hear the bearings
turning after ive shut the engine off. I don't off road and am taking it
fairly easy speedwise, The revs are never beyond 3000rpm whilst driving.
Its a UK model, and could someone explain 'WJ' ,'YJ','TJ'?

PS: I love my cherokee.
Thanks for any help and advice.
Cheers

Skimmer

It's a diesel in what foreign country? Of course, follow your
Owner's Manual. The Exhaust turbo depends on oil as coolant, if you stop
the oil pump the oil in the turbo's bearings will burn, leaving them for
next start up. If you put it away wet, it'll died, like the horse.

Re: Newbie Turbo question
 

Go with the manual.

The CJ,YJ,TJ are short wheel base jeeps:

The Cherokee you have is called the Liberty in the US and is the KJ.
The previous Cherokee is the XJ.

The current Grand Cherokee is the WJ (99 and up)
The previous Grand Cherokee is the ZJ.

Re: Newbie Turbo question
 

Get yourself a "turbo timer"--it will keep it going based on runtime
parameters.

Caveat: I don't know if they are available for Diesels!
