No, not a good idea. the specific heat of water is 4182 J/kgC where air is 1005 J/kgC. at a certain pressure. Water is actually a pretty amazing substance.
exactly,
you are right
but it still looks like, compressed air injected into engine\'s cooling system may work for a short distance of 10 miles
travelling at low speed

I\'d bet 10 miles is far too far. You might make a mile, then give it 40m to cool off. Repeat. Start early
I bet you\'d get further with it filled wth water & the rad cap removed.
But you\'re well into rolling the dice with all this, it\'s seldom a good idea. For a garage 54 style vid with a shot engine, sure.

\"Blown Head Gasket

The purpose of a head gasket is to seal the combustion gases within cylinders and prevent coolant and engine oils from leaking into the cylinders.

When a head gasket is broken, it can result in compressed air from the cylinders entering the cooling system as they are being blown into the water jacket.

As a result, bubbles may form in the coolant reservoir, which is why it may appear that your coolant reservoir is boiling.

Don\'t be silly.

Let him try! That way he will get just far enough from home to be really
inconvenient when the engine block seizes up completely and expensively.

The non diesel irrigation engines I keep bringing up are nothing but car engines adapted for irrigation use. They range from the 292 Chevys to the 454 cids. It\'s a fair guess the sensors are in the same places whether under a vehicle hood or under the stars.

Thank you
but what I get after 1 minute of engine running in idle is white cloud of water vapour at exhaust system, so no chance
to drive such car.
water filling cooling system makes no difference
if I remove red cap I get all the cooling fluid ejected

Radiator sealer injected into cooling system failed to work
so I expect to start short tests iunjecting compressed air into cooling system.

It would be nice to redirect air from the turbo charger into ccooling system, as a source of compressed air.
Unfortunately old car comes with no turbo charger installed.

454 cid ??? How much water are you moving? Has to be huge.

This is Darius the Dumb. He couldn\'t find his bottom with both hands. What he needs to do is get the car towed to a garage who could replace the head gasket for him, and probably mill off the mating faces to get them flat again. His half-witted experiment have probably got the block hot enough to warp it.

with a big of luck he\'ll get coolant in the oil and ruin the rest of the engine while he\'s at it ...

I\'ve seen it done with an old milk carton. It worked.

The non diesel irrigation engines I keep bringing up are nothing but car engines adapted for irrigation use. They range from the 292 Chevys to the 454 cids. It\'s a fair guess the sensors are in the same places whether under a vehicle hood or under the stars.
454 cid ??? How much water are you moving? Has to be huge.

I think I might\'ve seen one center pivot set up for 1000 gpm. Most are in the area of 700-900 gpm.
One other issue is gpm at what pressure? The old water drives ran best with pressure of 70 psi. They had sprinklers that would shoot maybe 40 feet or so on both sides of the pivot as it moved through the field. Wells were set up to pump, say 800 gpm at 70 psi.
Gearhead ratio is something else. The vertical shafts of wells are set up to turn 1760 rpm to match what an electric motor would do. Most gear heads are probably 6:5. The power unit would ideally run at 2112 rpm. Some gear heads are 11:10. A bigger than needed power unit could run a bit slower with those. Maybe it would last a bit longer.
Gallonage is a bit limited due to the soil composition. Dropping too much water at a time leads to runoff. Low pressure pivots (35 psi) have been the norm for maybe 40 years. Their sprinklers don\'t shoot as far so there is a practical limit for gpm on how much water one applies in one pass around the field. Most in south central Nebraska are probably set up to put on 1/4\" at maximum speed. Farmers usually don\'t go over maybe 1 1/4\" in one circle.

Options:
tow it
trailer it
replace head gasket, sandpaper machining the block or head if necessary.
Go a mile without coolant then cool off.
Remove rocker arms & sparkplug on bad cylinder then drive with coolant. Blow cyl out & add a bit of oil afterward.
Any more?

That\'s a HUGE amount of water, on the order of a CCF ( 100 cubic feet ) per minute! Your well must be tapped into a reservoir. How do you determine when and if the fields need water? Evaporation pans, tensiometers?

We\'re really fortunate. The Ogallala Aquifer is a big resource. There was some issue of drawing it down too far. The state government set up natural resource districts to manage irrigation. They don\'t interfere. Static water level was lowest in 1978. There will be pumping controls if the level ever gets that low again. Right now it\'s about 8 feet above that.
Lake McConaughy run by the Central Nebraska Public Power District does supply water to about 220,000 acres. I had to look it up. It\'s the west part of the state. Some here if you\'re interested.
<https://irrigationtoday.org/features/aging-infrastructure-the-next-100-years/>. I\'m under the impression it\'s small compared to projects out west.
Irrigation in my area is supplied by private wells owned by the farmers/landowners themselves.
I think most farmers use the tried and true eyeball method. Timing is a factor. A corn plant needs most of its moisture as the ear is developing. There are crop consultants to help guide them too. Soil moisture probes would be the handiest tool
Farmers are a bit like royalty in a sense. Farms are pretty much passed down from one generation to the next. It\'s one farm family buying out another family if there is land up for sale.

Radiator sealer injected into cooling system failed to work
so I expect to start short tests iunjecting compressed air into cooling system.

It would be nice to redirect air from the turbo charger into ccooling system, as a source of compressed air.
Unfortunately old car comes with no turbo charger installed.

Ummm... head gasket is not that difficult to replace.

True, but you may need to re-plane the head, this can be done with
sandpaper and a flat surface. or you can contract it out to a machine
shop. you\'ll also need a torque wrench as getting the correct
pressure on the new gasket is critical.

\"Blown Head Gasket

The purpose of a head gasket is to seal the combustion gases within cylinders and prevent coolant and engine oils from leaking into the cylinders.

When a head gasket is broken, it can result in compressed air from the cylinders entering the cooling system as they are being blown into the water jacket.

As a result, bubbles may form in the coolant reservoir, which is why it may appear that your coolant reservoir is boiling.

Can the coolant be replaced with compressed air for engine cooling for a short distances ?
No, not a good idea. the specific heat of water is 4182 J/kgC where air is 1005 J/kgC. at a certain pressure. Water is actually a pretty amazing substance.
exactly,
you are right
but it still looks like, compressed air injected into engine\'s cooling system may work for a short distance of 10 miles
travelling at low speed

10 miles! finally we get a value for short.

If an engine runs out of coolant, the oil starts to boil off, when it
runs out of oil it\'s game over.

If you keep the oil level up 10 miles should be possible. ignore the
coolant. if it has an automatic transmission you\'ll want to be
watching that that doesn\'t overheat too, becacause usually that\'s
cooled by an oil-water heat-exchanger in the radiator and that will be
unavailable or under-performing.

But seriously if this can wait weeks for resolution, get someone to tow
you. They make ropes for that and they\'re not expensive.
