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
