If you're quick you can change it without losing too much coolant. Just make sure the engine is cold and the new one is ready to go in...
Welcome aboard. Nice looking van you picked up.
We are having an event in your area in Jan over the weekend of the 18-20th in Fremont at the Ramada Inn just off I69 on the East side of the exit. You should at least stop by for a visit and meet some really decent people from the board. Then we are having the Main event down just east of Indy in Greenfield over the week of July 4th. Both of these can be seen here at the top of the IDI section in Sticky Threads.
By the sounds of it your glow plug system is working correctly. You might have the timing checked. Best shop I found when I lived in Fort Wayne was http://www.craigvillediesel.com/ south of the Fort in Craigsville they are good people and will treat you well. The owner used to own an IDI back when I was using them and has many years of experience of working on them.
I will warn you to stray away from Dave's Diesel in Angola... he's a bit of a scam artist and I know this from personal experience...
