4320 Intake Air Heater Working?

[sunnyside360]

It was -9 deg F here last night and +15 deg F around 11:00 AM today when I tried starting my 2010 JD 4320 tractor. Battery seemed to turn the engine over fast enough but just would not start. Tried pushing the key for 10 sec to activate the intake air heater and did not see any difference when trying to start. Then held key in for 30 sec with same results. I suspect the intake air heater may not be working. Does anyone know how to check the air heater? The dash indicator is illuminating when pushing the key.

If you raise the hood and preheat for 15 or 20 seconds. You should be able to touch the intake heater and feel temperature difference. If you can't tell, check it with a meter. You should get 12vdc when in preheat mode. Are you getting exhaust smoke? What color?

I just checked the tech manual on that machine. It shows glow plugs. Are you sure of your information?

Kevin, I don't have the 4320 shop manual. I posted based on info found in my owner's manual shown below and what was found here on tbn when searching on the topic.

9. For cold weather starting, use the intake air heater system. Activate the intake air heater system by pushing in the ignition key switch with the key, and holding it there for the required time:

10 - 15 seconds for temperatures as low as -18ｰC (0ｰF).

15 - 30 seconds for temperatures below -18ｰC (0ｰF).

Could be a serial number break. Look under the hood. The intake heater looks like a spacer with a wire on it.

not sure if it means that it is working, but when i push my key, i can hear the heater 'click'. don't know that i can get to mine to feel w/o removing the side panel...but i sure would like to find out! just don't feel like removing the loader to get the side panel off....of course, when it WON'T start one day, i won't be able to get the loader off to remove the side panel! anyone else not able to remove side panels w/ the loader on? i have a 4300.

i'm usually in a hurry when i need to use it for snow removal, but one of these days i need to actually get around to checking it.

I'm assuming you got winter fuel?

I don't know what they cost, nor how hard they are to install, but you could invest in a engine heater and see if it starts as normal then. that would determine if it's a heating issue. Just a thought.

I also hear a loud click (relay) when depressing the key but don't know if the heater is actually working. I'll try holding my hand on the manifold after pushing on the key for 30 sec.

Are you plugging in the block heater? and it still wont start?

Almost sounds like fuel might be gelled up?

Good question. I use Power Service additive (white bottle) year round. It's the same fuel (large storage tank) I use in two other diesel tractors both of which started right off with no difficulty yesterday.
