If its a diesel, it has em. No light, just listen to the clicks. Turn key just before starter... you'll hear a loud "click". Wait for it... you'll hear another click, after 2-5 seconds. Now start it. If its cold, you may hear a series of "click-clicks" as the afterglow system continues to heat the plugs, for up to 30 seconds or so.

Winter time, this is obviously very power hungry, so make sure you have a good battery (or batteries) with lots of cold cranking amps.

Thanks Phil. At what temperature do these normally come on? Temps have been running around -2 to + 3, I get the two clicks, but the glow plug indicator light doesn't come on. Is that what you mean by "no light"?
