Earlier 7.3 ps had glow plugs i kno nuthin bout the newer stuffI stole a pic of those heaters. It would be nice to get a threaded freeze plug for the heater outletHeres their pdfhttp://www.kimhotstartheaters.com/pdf/tps_pages.pdf
Power Stroke is DI, shouldn't need them. I don't need my glows on my M-TDI unless it is below -10C.
Real diesels just come with one I think. I'd clean the hole, and use a touch of rubber lube, clear synthetic, or marine grease.I don't need the cold start thing either.

The ones that go in the freeze plug has a much lesser chance of it.Call me skeptical. They are thermostatic and shut off when they reach 175F. (Oh, and they're surrounded by water.)The freeze-plug units are more likely to fail, since they are more exposed to debris, salt-spray and leakage from valve-cover oil. That's why I changed to the hose units.

Freeze plug heaters more likely to fail? How did yours fail? A heatet is a very simple device and should last a long long time if designed well, made with good quality materials w good workmanship. Freeze plug heaters has no thermostat (that can fail), it does not have 2 hose clamp connections that can fail, it puts all the energy into the coolant (hose heaters lose some energy heating the ambient air), freeze plug heaters is less of a fire hazzard. Sounds to me freeze plug heater is a better choice.

Sounds to me freeze plug heater is a better choice.I figured if I didn't put it back into the block, I'd use it to warm my coffee Its about as simple as it gets - unless it leaks and as 745 turbogreasel mentioned, a bit of marine grease on the O-ring should take care of that. The hole it fits into is in perfect condition (no pitting) so I should get a good seal.As for glow plugs, even though it only gets to "45" here (So Cal), having only three of four working almost doubled my crank time in the morning. After all, this is an IDI not DI and needs a bit of help.The block heater will never get plugged in unless I visit the North in the winter months - and I just may.
I find they outlast the regular freeze plugs
I believe the heater is made by Temro. http://www.phillipsandtemro.com/userfiles/file/ZEROSTART_2012_CATALOG(1).pdfThe numbers are:400 watts115 VoltsLR1843It's made in Canada so it's gotta hold up right?I didn't find any install instructions but browsing the site and install diagrams leads me to believe there's not much more than tightening the screw.I'll stick it in with some vaseline (that's sounds kinda weird) and move on.Thanks everybody!
OE Freeze plugs are mostly tin, and rust out, the flange on the block heaters is way thicker. The only time they fail is if you run water without coolant for a looong time and the screw rusts through.It's possible the o ring could dry out, but it's just a generic rubber ring if you did need a fresh one.I've been a mechanic since 93, so I've looked at a few motors, and personally had a few where all the freeze plugs needed replacement, but the heater sealed fine(although it may or may not electrically function).

I read your statement: "I find they outlast the regular freeze plugs" with the "they" as the hose type heater and "regular freeze plugs" as the freeze plug type heater, prompting my question, when you really meant: "freeze plug heaters outlast the freeze plugs.Do freeze plugs rust out? If they do, it is not tin. Tin is quite rust resistant.
