Coolant Heater

I bought a JD-2030 and want to put a coolant heater on it. Can I just plumb it right into the line that comes off out of the bottom of the radiator? Also I am having a hard time getting a serial number for an owner/operator manual and was hoping someone might have a good idea for me to find out the model number so I can get a manual ordered. Trying a couple different methods but the serial number is too faded.
 
If the engine has no block connection. They do make adapters that will fit into the hose. Intake for the heater comes in the bottom.
Outlet goes to the top.. I believe Kim Stat makes a heater that fits in the bottom hose. And heats the water from there.
 

Tank heater from the Free online JD parts book. Pick what ever wattage you want . I have a 1500W on the shelf that I have to get around to installing. https://partscatalog.deere.com/jdrc/sidebyside/equipment/70746/referrer/navigation/pgId/104260
 
If I cant get the serial number do you guys possibly know how I can tell which of the 2030s I have? Was told it was a 1976 but cant verify that with a serial number I am trying to order some manuals for it
 
I believe the 2030 was built 1972 through 1975. 2040s started in 1976.

Where is the S/N tag located? The tag location through S/N 187300 was on the right side of the transmission case above the footrest. 187301 and on the tag was on the right side of the front support above the axle. I thought the numbers were stamped in the tag, usually a little rubbing with ScotchBrite brings them out.
 
There was a serial plate on the engine in front of the right foot rest. Couldnt find any other place. It looks to me like the serial plate might have ended in 01875T. That five could be a 6 or an 8
 
My understanding is the serial number should have 6 digits. The T is supposed to stand for the John Deere Dubugue Works. Does your engine tag look like this?

After talking to the guy at John Deere it looks like we have narrowed it down to two different models. The older model has the tractor serial plate in the right front and the second one has the serial plate under the seat some where. I cant see where either would have been. Until I get the coolant heater can I just put a couple heat lamps on it. Pardon my ignorance as I have never owned a diesel and not sure if I would have bought one if I would have fully understood the cold weather starting problems they have. Hopefully just a blip on the radar because when started it works perfect for what I need it for. Thanks for all of your help!
 
John Deere 2030 Tractor Operators Manual (SN# 0-187300) JD-O-OMR50675

John Deere 2030 Tractor Operators Manual (SN# 187300- )JD-O-OMR59805

Are the two different owners manuals I can find. From what I understand the engines are the same from what the guy on the phone said after looking at them. I am not sure just going off what I was told by the guy at John Deere.
 
So you are still thinking the same model - 2030, just not sure which serial number range. I don't find any info on a serial tag for these under the seat somewhere.

My earlier post was based on the info about serial number locations and breakdowns from the JD parts catalog. You can review this info in the introduction section of the on line 2030 parts catalog (PC1289) at
https://partscatalog.deere.com/jdrc/

This is the manual for the early serial number range: John Deere 2030 Tractor Operators Manual (SN# 0-187300) JD-O-OMR50675. These tractors would have had a tag on the right side of the transmission case, above the foot rest. Look for the two holes where it was anchored with blind rivets as the engine tag is.

The later model serial number range manual is: John Deere 2030 Tractor Operators Manual (SN# 187300- )JD-O-OMR59805. The tag for these tractors should have been on the right side of the front support above the axle. You may see the rivet holes there.

If you can find the rivet holes you can decide whether it is an early or late model to order your manual by. Dimensions of the tags would have been close to the same as your engine tag.

Some pertinence info from the Phillips Temro "Zerostart" catalog
 
I will for sure look for those holes but it has a crazy amount of paint on it so I am hoping I can find them.

In the mean time it is starting really hard so I was just going to put in the heater that goes with both of them from the factory but I am not sure where it gets plumbed into and from. Part number AR72957

This may help you, here is a photo of where a tank heater was plumbed into one of my 2030s. To get the thermo-syphon to work the heater inlet must be below the outlet on the type of tank heater in the photo and the JD one. The tank outlet must be below the point hot water goes back into the block. The hot water return point to the block must be above the block outlet for water going to the heater inlet.

Bob,

Good info. I agree the in block heaters are great and I would recommend them ahead of tank or hose type heaters, but at least some of the 4219 engines don't have the 1-5/8" plug in the block water jacket, as in the photo I posted. Also I have found the in block heaters don't always fit as the manufacturers describe. Been there, done that. Now I always try to get the installation info and check for the location and access to the location, before I buy. The tank heater is about the best option for these tractors and is what the 2030 parts catalog shows, as Bryanmedlin found.

Would you suggest using the factory one or using one of the other newer models? Thanks that helped out a lot.
 
What do you mean by newer models? Unless your engine is different than I think it is, it will not accept any of the in the block type heaters Bob's post showed. I think you will be fine with either the factory tank heater or one of the aftermarket tank heaters. Kats and Phillips both make good tank heaters (and cost less). 850 to 1000 watts will be plenty, (1500 watts maximum) no need to go larger.

When you say under the seat do you mean; under the seat on the side of the transmission, or actually under the seat on the cover the seat mounts on? If we are describing the same place, side of the transmission, that would be a tractor S/N 187300 or before.
 
I mean under the seat on the side of the transmission. The holes are consistent with the plate on the engine.

What I was asking was I noticed the the factory tank heater was plumbed right into the two ports on the side of the block and the other tank heaters I was seeing looked to be made to be plumbed differently. Unless I am looking at the hardware that comes with the kit incorrectly.
 
The heater in the photo I posted is a Kat's. I think locations shown in my photo are the best ports to use on these engines, and all tank heaters without powered circulation, would plumb about the same. Some heaters have the inlet port and outlet port both on the side like the JD parts diagram. Some have the inlet on the side and outlet on the top, most of the Kat's and Phillips heater are this style. They function the same, hardware for mounting will vary by manufacturer. Hose lengths will vary on how you mount them. Whether it is a side or top outlet, the important thing is to mount the tank with the heater outlet above the heater inlet and below the point where the hot coolant returns to the engine, that allows the hot coolant to rise developing the natural thermo-cycle action for circulation.

The AR72957 number you got shows as NLA and subs to RE313366, when I checked it. If you look for photos on line at the Green Part Store site of the JD RE313366 heater it shows as 1500 watts and looks like a Phillips 41 series heater, if you compare it to photos on their site. Check with the store for YT as they may have a similar heater.
