Gday all, i have a 97 2.8 rodeo and the glowplug system has always worked faultlessly. Lately though, the glowplugs have been coming on and off as normal but the CSD wont disengage causing the engine to be very loud. Anyone know what could cause this? I disconnected the thermo switch on the thermostat housing when the engine was hot and the glow plugs glowed for maximum time but the engine still sounded the same. Any ideas?
Cheers

Unplug the wire on top of the injector pump should be green cap cover and see what happens if it makes any difference I have this disconnected on my 2.8 rodeo engine and it runs ok with out it.
Its the 1 above the fuel solenoid plug.

Re: 4JB1 glow plug system
the csd is inside the injector pump behind the steel plates held on with 2 10mm head bolts or sometimes allen key heads, its just a termal wax stat thing, ive never seen one play up, as ive said that idler bearing to the injector pump fails and the idler and injector pump gears chatter together, engine runs fine is just normally twice as noisy
