Will they start from cold with no glow plugs? Inquiring minds want to know. Hatterasguy says his will. When's the test?

Mine sure wouldn't start w/o GP's. After a new relay and 6 new plugs she fired up beautifully.

Any diesel will start without glow plugs, it just takes muuuuch longer. When I first bought my old 300SD, all the glow plugs were shot, and it would take a couple of minutes of solid cranking before it would fire up (the starters on these cars must be EXTRA heavy duty!).

An 80's vintage Yanmar 220D tractor I had would start w/out glow plugs. The glow cycle was for winter starting according to the owners manual. It also had a manual compression release so you could spin the engine faster during cold starting.

Define "cold."

I could just barely start mine in ~45F weather when the glow plug fuse went south for the winter. Maybe six rounds of cranking the engine for 30 seconds each. Very impressive smoke cloud.

My JD2040 doesn't have glow plugs. But then, it's a DI engine and it has provision for using a "Deere-approved" starter fluid. Even on the coldest morning last winter (21F) she started just fine w/o fluid.

I know the 617 will start pretty darn cold, mine only refused when it got to the high 30's with 4 dead glow plugs.

Last summer, mine began to start harder than its normal instant start so I took it to the shop. They told me I had 6 bad plugs. So apparently mine will start with no plug help. In 70* weather.

My Bobcat skid steer with a Kubota engine has a toggle switch for the glow plugs. On cold days you hit the switch for a couple of seconds and it fires right up. I can start without glow plugs down to 30 deg. or so.

I wonder if it would be possible to implement an air intake heater like some off road diesels use, also do the new mbs have gp's at all or do they use computer control like the newer cummins heavy dutys, cats, or detroits.
