Glow Plugs in a 574

I have a 1972 IH 574 with a IH D239 diesel and was wondering if there were any places to put glowplugs at? Would I need to put them in the intake manifold or in the block?

Not really , I guess one could rig a heater like some of the ac tractors (190 $ 185) had in the
intake but those used a small injector for starting fluid. In the TD 7 & 8 ih dozer they had a cold start position on the pump control that also helped start them. If Desiel tech chimes in he might tell you how that worked.

Are you using the cold start position when starting that's on the stop/start/run cable/lever? Fully IN is run, pulled back and JUST TOUCHING the spring loaded stop is
START, and fully compressing the spring loaded stop is OFF. If pump is in good shape that's how engine should be started, but DO NOT open throttle past half way or the
start feature won't work. I have a tank type block heater on my Hydro 84 engine which is similar to the 574 that makes cols weather starting much easier.

no glow plugs in a 574, a block heater will help a lot.

On the 185 the heater that goes in the freeze plug hole is the way to go,maybe the IH could use one of those.

Hi Dieseltech, the 574 and 454 tractors sold in the UK also had thermostarts fitted to the inlet manifold. When working for an IH dealer I sold a lot of these tractors including Hydros for loader work. We had a batch of 454 and 574 tractors with faulty thermostarts and the farmers would ring up to tell you they have diesel fuel running down the windscreen as all UK tractors were fitted with safety cabs.

Hi, see attached photo of my brother's CIH 495 with 3 cyl German D-179, it has the Thermostart Option instead of the ether injection, in the photo see the glow plug in the intake manifold just above the
back of the alternator. The black fuel line that is connected to the glow plug goes to the return fuel line and the red wire is connected to the ignition switch. The ignition switch has an position between
ON and Start that you hold it for 30 seconds that energizes the glow plug and when the glow plug gets hot it starts burning fuel from the return line in the intake manifold. This glow plug works good down to
about -10F but colder than that he uses the 1500 watt recirculating tank heater that is in the photo.
My brother has 5 of the IH German Diesels including an IH 684 with D-239 like your 574 and he has put 1500 watt tank heaters in then all, plug then in for 30 minutes and use the cold start position like
Dieseltech said and they are good to go.
The only problem with the glow plug is the elements appear to crack over summer with the engine vibration and then the first time you need to use it in the winter it dose not work. I try to suggest to my
brother to remove the good one in the spring and install an old one but that never happens.

That's a good choice, problem is the German IH Neuss blocks don't have any freeze plugs to put a heater in. That's why I have a tank type heater on the Hydro 84.

I had a 574 and it was cold blooded-it did not like to start below 50* unless the block heater was used. The
style JimB2 showed is what mine had, and it worked great. It only needed to be plugged in for about 20
minutes in cool weather and it would start. Down to 10* maybe an hour or so. Mark.

We have a lower radiator hose heater and will start down in the -20 range well for us. Our 574 seems like the start position on the fuel lever doesn't matter where it is set at. The 674 does matter for starting in cold weather in the start position. Where do you guys put the top hose into for those tank heaters. I 'm having trouble with durability of the hose heaters the last couple.

My tank heater is just in front of the starter. I put a tee fitting in the block drain for both heater inlet and keep the block drain cock. The top heater hose goes up across the valve cover front if I recall and goes to a fitting at top front of engine near the thermostat housing. I's a tight fit but works well as the tank heater is thermostatically controlled.
