Damammel do i put the heater on the house coming out of the bottom of the radiator or the one that comes out of the top. Also do i need to buy a new hose or will whats on it work

you would need to cut your current hose. I think if i remember right and what he said he bought off the shelf hoses that had similar bends on the ends and he cut the middle to put the heater in.
He then takes the assembly off in the spring and runs the factory hose.


I think you can put it in either hose the water will circulate and heat all of it. I think there is more room on the top and its deffinitly easier to get to. I know when i replaced my radiator the bottome was always a pain to get to.

I went down to my work earlier today and got a jump box and hooked it up to the tractor and i still could not get the tractor to start. Its seems to turn over fine until the compression is engaged back in then it seems like it cranks really slow. While cranking i have very little puffs of white smoke coming out of the exhaust. But nothing else happens. Could it just be so cold that it wont start, the temps in northern Kentucky have been single digits at night and teens during the day. But like i said earlier i had it running a few days ago. Im going to try this weekend when i have more time to wrap it in a tarp and put a heater under it. I have no idea what the problem could be with this thing ive only owned gas tractors before this one so this is my first diesel. So i would appreciate any help i can get. Also one thing I forgot to mention was i noticed when i was cranking on it was one of the wires tied in with the positive wire coming off the battery to the starter got red hot and smelled like it was burning could it be a bad positive wire

You will get nowhere without a volt/ohm meter. That appears to be a high resistance, either bad connection or corroded cable, giving the appearance of too small of a wire for the amperage.

These little Yanmars will meet your expectations after you renovated it back into conformance with with Yanmar's specs. Sounds like you have a little bit of renovation work to do to get back in spec.

Specifically, if someone added a wire in parallel with the primary starter cable and that additional wire is burning up - you have a clear sign that the primary cable designed by Yanmar is no longer carrying the intended current. Some prior owner recognized this and made an ineffective hack. Replace the primary cable and discard that parallel wire.

Don't cut your original hose. Keep that for the warm weather. Cut up the hose from tsc. That way you can get another if you cut wrong. It's on the lower hose also because that's where it operates properly.

Did you by chance spray this engine with starting fluid? If you did spray it that could be your problem... Starting fluid can bust the piston and rings... NEVER spray starting fluid in a yanmar engine...

My Yannie hates the cold also. Over the years I have found that there is a "sweet spot" for the throttle that will get her going in the cold almost every time. Any deviation and it's a no-go. Still, any colder than 30 and the hair dryer comes out. Mostly mild winters here, but if we get extended periods of cold weather I stick my magnetic block heater on the oil pan and just leave it on. Having pre-warmed oil gets her spinning much better.

Yes, they are little work horses. Lord knows I have had fits with mine, mostly because of the previous owner's abuse and deferred maintenance. I was griping and cursing this tractor, but she's growing on me. I have replaced all 4 tires, radiator, starter solenoid, battery, battery cables, radiator hoses and I'm sure more. :laughing: But, when I turned her over for the first time this year after sitting nearly 6 months, she came right to life. I was duly impressed.

I installed a lower radiator hose heater on the tractor and if i plug it in for a few before i need it it fires right up like its a hot summer day out, i guess it was just to cold outside for it without some heat.

Glad to hear it worked out for you. Which hose did you use for the install?
