Had trouble with our 98 Jackaroo starting and have looked in the forum for some very good advice on this problem. While following this up we were wondering if anyone knows what the glow plug on the dash is for. Not the glow plug light that comes on above the speedo when you turn on the ignition but the push in switch next to the clock on the dash??? There is nothing about it the manual.
Would like to thank all who helped with our last post on camper trailer conversions

Has your trouble recently arose? Like after a service?
A friend of mine was getting his Jackaroo serviced by Holden and they put the fuel filter in the wrong way around, creating problems with starting.
Just a thought.

If your engine is the new 3.0 hi tech unit, and you are using the correct oil (probably 10W-40) then your injector seals may need replacement (the other biggy is of course oil that is too thick). There was a recall on the seals for the Oct 98 + sales.
They will inhibit starting if not done. If you get it done, make sure they check your valve shims at the same time. Very expensive if they have to do it all over again later (expensive enough as is).
In my 99 SE handbook, the Diesel Quick Warm Up Switch is described on Page 1-13.
Says something like "when the outside temp is below 15C and the engine is below 80 C turn this circuit on prior to starting as usual. Seems it is a helper circuit of some sort - can be left on - it deactivates after start. There is of course no explanation as to what this actually does in tech terms.Get me outa these suburbs !

Hi Foxer,

I have a 2000 Monterey. The manual on page 1-13 describes the operation of the "Diesel quick warm-up switch" which is the one next to the clock.

It states -

"When the outside temperature is below 15 deg and the engine temp is below 80 deg, depress the switch to operate the engine quick warm-up system. The indicator light comes on when the switch is in use. The system will deactivate automatically, or can be deactivated with the switch."

Hope that helps!

according to an article in Overlander Mag August 1998 the quick warmup system
consists of inlet and exhaust butterfly valves which restrict gas flow. This does not help starting - only warmup time.
There is a very good article on the 4jx1 engine in The Automotive Engineer magazine march/april 2001.
happy motoring

Assuming yours is the 3 litre TD, Holden fitted a second starting battery to the later TD Jackaroos to cure their cold starting problem. These batteries were merely wired together in parallel to provide double the cold cranking amps.
