Help ID a block heater

Bret4207 · Jan 17, 2009

Okay, I have a DB 990 that starts....well, not so good at -20F. I don't like ether, so I was going to put a block heater in when I noticed one of the previous owners had already put one in. It sits in a freeze plug and has a recessed spot for the female part of the wires to pug into. 3 male studs in a 1/3 circle about an inch wide. Anyone have any ideas on the brand so I could try and get the power cord instead of putting in a new unit?

I am not sure those heaters are made anymore. If not installed properly the element will touch the block and burn out.I worked on back up generators for forty years. The best ones I have used came from universal heaters.Another heater OEM is Kim Stat. You might check with the local Cummins dealer,he should have a book on heaters.I will see if I can find my heater book

I think I would just replace the unit, not hard to do, and may be less trouble.

I agree with Cumminsman. If you can find the heater kit. You should just change the whole thing. No telling what shape the heater is in. So you may spend money on the cord and find the heater shorted.The number for The Universal Engine Heater Company is(509)328-1220. They make very good heaters. I have used them for years. Not sure if they make freeze plug type heaters. But at least you have the number to ask.I installed one of there heaters 17 years ago and it is still working.Not saying they all last that long but they do make very good units.

Clean up the old heater, there is usually a company logo on the outside. Clean/wire brush /magnifying glass ;-)

Check the link, bottom of the page under accessories, click enlarge to see the shape of the plug.

If you intend to install a new cord it would be a good idea to perform a resistance/continuity check on all three terminals..........on the off-chance there is a "short" or "open" in the heater

There should be continuity(with slight resistance) between each of the two outer terminals(approx 10 to 30 ohms depeding on wattage of heater)......If there is no continuity(open) the heater/element will not work..........

There should be NO continuity between either of the outer terminals and the center terminal or the body of the block heater..........If there is continuity there is a short and installing a cord will be dangerous..................

For replacement heaters, these guys have it all:

Thanks to all. Jon had it with the Katz heater. I'll do the test as recommended and see if it's worth it first. I've always used the heaters in the lower rad hose, but thought in this case it'd be much easier.

Thanks a million guys!
