well its cold and i was wondering if anyone found a nice block freeze plug heater easy to do without removing something big.I had one on my chevy and it was nice....i have a 92 pick up 4X4 22re motor with 246000 on her and runs well just trying to help her out thanks any suggestions will be appreciated.
Yea, I asked this a few months back and it turns out that most block heaters are a universal fit, available at most autoparts stores. Most of them install through a freeze plug, which will require some removal of parts to gain easy access. Goodluck!
yep. theres a couple other options too. they sell pads you can put on the oil pan to help keep the oil moving. they also sell batt heaters & blankets as well as coolant heaters that go on the radiator hoses. Best bet is the freeze plug type, but they're the hardest to put in.
On a 22RE - getting the passenger side front freeze plug is pretty simple. It helps to have a slide hammer....
Hammer the plug INTO the engine.
Use vise grips to grab the plug by the edge.
Use a OTC slide hammer kit. It has an attachment that fits into the screw threads of vise grips. Thus you can use the vise grips to GRIP and the slide hammer to PULL.
I spent more time assembling the freakin hammer and extensions than I took to get the plug OUT.
The freeze plug block heaters are not that hard to install. On my 82 I think its in the second hold back from the front on tha passenger side. Knock the one side in and pull the plug out and put some sealent around the block heater, put in and tighten up and plug in. Easy as that. Oh and you gotta drain the coolant first but thats a given. I've got an inline lower rad hose heater in my new yota diesel and it works nicely as well. Plug it in for a few hours at -20 and she fires right up like it summer time.
Just an FYI to resurrect an older thread, I found the ZeroStart brand block heaters on sale online for $15.04 each. They are a bit down the page as part number 3100049 (you can corroborate it from ZeroStart's catalog http://www.fuelinjection.net/zerostart/index.html
as well). Cheers

The 22R setup on my 1987 looked like a good candiate for that application. I'm wondering though if there is enough circulation through the thermostat when it is 'closed' to allow the coolant to circulate thermally. I've had it plugged in a couple hours and only warm close to the heater in 30 degree weather (it's a Kat 16500 600W). Never really compared the circulation pattern on a diesel which I though would be similar. I'm staying patient, but wondering?
I have a vague memory of the 22r# Toyota block heaters that went into a freeze plug hole having a tendency to seep. But in all honesty we didn't do many since freezing wasn't a issue in our area.
Im in a cold climate( Northwestern Ontario) and the 22RE will start in any weather provided you have a good battery. That said for easy starts I have a block heater and a trickle charge permanently installed.
i'm not sure what the cold start strategy is with the engine controller and fuel injection but every older inject 22R i've had does not want to start in the cold. If I hit it with starting fluid, we the people. Of course a good battery helps but I would like to give it a fight chance by heating it.
Just can't figure what is up with the lower radiator heater hose approach. you see some folks say drill a hole in the closure plate on the thermostat and others say that the pipe is large enough to have counterflow. I don't know, I installed mine on the rising angle in the lower hose on my 4x4 and it sure doesn't seem to performing very well so i'm considering the hole in the thermostat. I could tee out of an upper heater hose and then tee that into the upper radiator hose with a valve in line on the bypass from the heater hose, then I can shut it off during normal operation. i've got that kind of a setup on a cummins on a boom lift and it heats really nicely but i'm a little less aware of internal geometry or impediments in the 22R. would appreciate hearing anyone's experience.
One thing i noticed is that these 1 and 1/4" and 1 and 1 1/2" lower rad hose heaters are much lower wattage, e.g. 600 watts, whereas the 5/8 heater hose varieties (for which there doesn't really seem to be as good a location to get good thermal circulation in this application) are 1000 or 1500 watts.
