 Topic: D15 Buda DIESEL Block Heater?? Where to install?
Posted: 04 Feb 2019 at 7:47pm |
Hello, I am trying to find the best place to install an engine heater for ice cold weather starting
It's a mid 60s i-60 / I600 D15 series Diesel Loader Backhoe
(with the Buda 175 cid 4 cyl)
Does anyone know the best place to install an engine heater?
The lower rad. hose is short piece between metal piping
should I cut a piece of the pipe and put a hose heater here,
or is there a better place to install one?
I think there are some small screw out plugs on the side of the block, is this where it should go?
,what size and type heater is best ? any help would be appreciated ! thanks!

If you go to Kat's engine heater site, I think they can match it up. I prefer the external tank type heaters, for ease of installation, and longevity. Never done one on this motor, so you'll have to do some research... IIRR, you take cold coolant from the block drain, heat it, and goes up into the head...

Here is what is shown in the D15 parts book for the diesel engine heater. 1000 watts will be plenty for that size cooling system. I believe cold coolant comes from the block drain. I'm not sure on those where the heated coolant goes. Often it is to the back of head or back of the thermostat housing. This says the discharge (heated coolant) tube goes to the thermostat housing. Heaters work best mounted vertically, or close to it, with inlet slightly below the block source point. Hose for heated coolant should continually rise from the heater to engine connection, with no sags in it, for thermosyphon circulation to work.

jerbob,
You can plumb one of this type heater to most engines of that vintage. With some research there may be an in the block heater for your HD16's engine. Check out Phillips/Zerostart as well as KAT'S. I would think 1500 watts in block or 2000 watts circulating tank heater like this one would be good on its cooling system. In the block heaters eliminate hoses to catch and fail, as well as the heat is inside the engine block.

With external tank type heaters, you need to mount the can, as close to vertical, as possible. If you mount it horizontal, the element will burn out...

I picked up a tank heater and still do not know where the correct block drain connection is
the block's ipl is online here (page 46);
it seems to show a 1/8" npt "expansion" plug under the tach connection area on the side of the block so I removed this plug but it had oil residue on the back, no water came out
it is straight in-line with the oil pressure adjust
I see other plugs on the ipl but they are not labeled
they are in-line with the plug I removed so I doubt they are block drains ?
I do see a plug approx. mid level on the same side of the block , not sure if this is the one I should connect to?
there is no "thermostat housing" on this engine,
the thermostat is a pellet type within the upper rad hose
There is a water inlet block on the top that has the bi pass pipe, it has a large plug on the back so it seems to be a good connection point for the top hose, just need to locate the proper lower plug to tap !!!!

The large block on top is the water outlet to the radiator, it is where your heated coolant line will hook into the plug you mentioned.
The block drain should be 1/4" npt. It had a peacock on the generator side of the block, in the parts drawing you posted. Try the plug mid level of the block you mentioned in your post. Water jackets usually stop mid way of a block or a bit lower.

thanks Jim.me,
I did More searching online,
I found a few actual block pictures online here;
Looking from the top down I see the sleeves run about 1/2 way into the block so I think you are right
the water line is not at the bottom where i was attempting to connect
I also see a pipe nipple about mid way on the injector pump side, (it must be behind the fuel filters on my machine)
I suspect this may be where a tank heater was connected
I will explore more tomorrow, the machine is in about 1 foot of snow thaw water
due to our 40 deg. heat wave so it's not fun working on it now (my boots leaked!)
( the starter is in the shop so I have to work on it where it sits )

There may be one on the injection pump side but I believe there is one on the generator side. I think someone recently was putting a heater on a D19, similar blocks and the drain was on the generator side. Look back in the farm equipment forum.

Yes, you were right Jim.me I connected to the drain on generator side (in about the center of the block)
the drain plug was an odd size that nether sae nor metric would fit well so I used a stud remover to turn it out
The kats tank heater is now installed and working perfectly thank you very much
the engine, the injectors and pump were all totally rebuilt less than 200 running hours ago.........but it still starts hard in zero degree weather and I do not like using ether
(I think the timing may be to advanced for easy cold start, seems to "kick back" a bit when cold thus straining the starter)
I had the starter rebuilt about 2 winters ago and it's back in the shop now I should have plumbed in a heather long ago!

Good to hear you found the right block drain and the heater is working.
