We have a cucv at work that we use for snow plowing duty. It has about 8 bad glowplugs, and absolutely will not start at anything below 40 degrees. The cold start thing is especially annoying because we only use the truck in the winter (It hasn't been 40 degrees here since early October). Our mechanic has been using a little shot of starting fluid to get it started in the morning. Yes, I know there are about 15 different warning stickers in the cab and engine compartment which warn that use of starting fluid (ether) will cause serious engine damage. However, it has been started like this every day for the last few years with apparently no ill effects. So, my question is, what gives? Why has the engine not broken a piston, or bent a rod or something like that. He only uses a little shot of ether outside the air cleaner, and that is all it takes to fire right up. We would just get some new glowplugs, but apparently they are getting hard to come by in the Army system.
