I wouldn't do it. Might have no use for the repaired radiator.
Leave it, or find another way to move it.

Absolutely not. You WILL fry something in the top end, either valves or
rings, possibly both.

If you must move the car, tow or push. Do NOT run this engine.

Hi,
Oil also cools engine. But I don't know how long the oil alone can keep
the temp in safe range.

This time of year, it should be OK. Watch the dash gages in case it warms
up, or the temp light comes on. If that happens, shut off the engine, lift
the hood till it cools down.

Cute !!

Oil also cools engine. But I don't know how long the oil alone can keep
the temp in safe range.

True, but some area's like around exhaust valve seats become very hot
very rapidly without aggressive coolant circulation. Oil circulation
alone will provide little if any cooling around these 'hotspots'.

Even full of coolant without circulation, these area's will quickly boil.

Personally, were it mine, I'd limit dry runtime to 20 seconds or less,
and then only under light loads. If I 'had' to move it further, I'd give
it 10 or 15 minutes between runs.

Keep in mind that even during normal operation, said hotspots are
'pushing' localized thermal shock limits.

Even 30-seconds is not safe if there is no coolant in the head. The rad
being missing is NOT the same as simply having low coolant-level in a
complete system.

Combustion temperatures are around 1,500-2,000 degrees F. That heat builds
in seconds if it can't be carried away; without coolant, the surrounding
metal will overheat /very/ quickly, creating the strong probability of the
head warping, which will cause head-gasket failure and poor valve sealing.

I don't know. But just for grins, this killfiled poster will
bring up something no one else has apparently thought
about. Cooling the engine isn't the only function of
coolant. It also lubricates the water pump. And I'd be
a lot more worried about running that dry for 2 mins,
than I would be about damaging the engine. But then
he needs 5 mins to go across his vast estate.....
I wonder if that's at 15 mph or 75?
Most of us with connected brain cells only take
radiators out of cars where they are not 5 mins away
from where they can be left for a few days to begin with.

Depends on the car and engine - what thermal mass does it have? Some
engines will run at low power for HOURS with no coolant. Others are
scrap in 5 minutes. The important thing is how long it takes to get
the critical parts of the engine heated up to the critical
temperature. If you are not stupid enough to pour cold water into it,
most engines can stand 300 degrees F without damaging the valves,
rings, cyls, bearings, block, heads or gaskets under light load.

HOWEVER - I would at least block the hoses and fill it with water, and
better yet short circuit the rad hoses. The water in the block will
take more than 5 minutes to heat to the point the thermostat would
open.

Without coolant the guage will in all likelihood never go up - or the
light come on. Bothe measure COOLANT temperature, not engine
temperature. No coolant, no indication.

I'm not reading everything in thread, but water could function as
temporary coolant, drained and disposed of. What's the big deal? I'm
old enough to remember when just water was used in warm months and
methanol added as antifreeze in the winter.

A bit of PVC and a pair of elbows works fine. Don't even need to glue
it together - just a wrap of tape to hold it together. Put the pipe in
the lower hose, fill from top of pipe, pop the top hose on, and start
it up.

That said -

My daughter's '82 Colt 200 blew the rad one cold and nasty night about
10 miles from home. I went out with 2 gallons of water and tried to
fill the rad. Water ran out as fast as I could pour it in. I gave my
daughter the keys to my car and told her to follow me. I started the
colt, took it up to 100kph and shut it off, letting it coast. When it
got down to about 30 or 40 I turned on the ignition, popped the
clutch, and took it up to 100 again, then coasted it down. Took 3 or 4
cycles to get it home to my driveway - where we put in a new rad the
next day. No harm done to the engine

Are you a mechanic???
I am. 30 seconds will not hurt ANYTHING. Period. The thermal mass is
highe enough to take a minute of no or light load running without harm
- even on a lightweight aluminum engine. - in most cases significantly
longer.

The Ccadillac Northstar can be driven 50 miles with absolutely no
coolant, without harm - and it is a FRAGILE engine. They do it by
rotating shutdown of cyls and reducing power output.

I would not run a dry engine for 5 minutes - but I have posted a
solution that works very well and is totally safe for a 5 minute run.
- short circuit pipe..

What is the sound of two killfiled posters,
posting?

Is this an exclusive club, or can just anyone be
killfiled by Home Guy? Do I need to wear a
tux and bowtie to be killfiled?

I don't know. But just for grins, this killfiled poster will
bring up something no one else has apparently thought
about. Cooling the engine isn't the only function of
coolant. It also lubricates the water pump. And I'd be
a lot more worried about running that dry for 2 mins,
than I would be about damaging the engine. But then
he needs 5 mins to go across his vast estate.....
I wonder if that's at 15 mph or 75?
Most of us with connected brain cells only take
radiators out of cars where they are not 5 mins away
from where they can be left for a few days to begin with.


The problem with some here is that they take everything so literally.
He probably just said 5 minutes to be conservative.

2 minutes would likely be safe. 5 would definitely be pushing your
luck.




Even 30-seconds is not safe if there is no coolant in the head. The rad
being missing is NOT the same as simply having low coolant-level in a
complete system.

Combustion temperatures are around 1,500-2,000 degrees F. That heat builds
in seconds if it can't be carried away; without coolant, the surrounding
metal will overheat /very/ quickly, creating the strong probability of the
head warping, which will cause head-gasket failure and poor valve sealing.


I don't know but my hunch is you are correct. That said since this
newsgroup seems indecisive about exact amount of time (understandable
IMO), I think he is well advised not to take a chance because I
think?? he has more to lose than to gain. Of course ultimately he
will make that decision.

Are you a mechanic???
I am. 30 seconds will not hurt ANYTHING. Period. The thermal mass is
highe enough to take a minute of no or light load running without harm
- even on a lightweight aluminum engine. - in most cases significantly
longer.

The Ccadillac Northstar can be driven 50 miles with absolutely no
coolant, without harm - and it is a FRAGILE engine. They do it by
rotating shutdown of cyls and reducing power output.

I would not run a dry engine for 5 minutes - but I have posted a
solution that works very well and is totally safe for a 5 minute run.
- short circuit pipe..


First, I am not a mechanic but I question the 5 minutes. I don't know
the outside temps his engine will be started but my experience shows
my engine reaching operating temps in less than 5 minutes. If this is
correct, then his engine will get pretty hot for a minute or so with
no liquid. As I said I'm no mechanic or mechanical engineer but this
sounds on the verge of dangerous to me. I sure hope he gets
confirmation on what you said, if he thinks you are correct.

That said -

My daughter's '82 Colt 200 blew the rad one cold and nasty night about
10 miles from home. I went out with 2 gallons of water and tried to
fill the rad. Water ran out as fast as I could pour it in. I gave my
daughter the keys to my car and told her to follow me. I started the
colt, took it up to 100kph and shut it off, letting it coast. When it
got down to about 30 or 40 I turned on the ignition, popped the
clutch, and took it up to 100 again, then coasted it down. Took 3 or 4
cycles to get it home to my driveway - where we put in a new rad the
next day. No harm done to the engine

Then the solution is simple. Have your daughter go to Homeowner's
place and follow him as he moves the car.

I just read your post you were referring to I think and in that post,
you did refer to running it with liquid ... therefore not dry. In
that case I agree if it's not much more than 5 minutes.

I wouldn't do it. Might have no use for the repaired radiator.
Leave it, or find another way to move it.
I would not run it f minutes. But you can easily make a "short
circuit pipe" to fit between the rad hoses, fill it with coolant, move
it and drain it.

Now that is a great idea.
I probably have a pipe for that too.
Sometimes posting on here is well worth it.

Thanks!
A bit of PVC and a pair of elbows works fine. Don't even need to glue
it together - just a wrap of tape to hold it together. Put the pipe in
the lower hose, fill from top of pipe, pop the top hose on, and start
it up.

I remember Cadillac advertizing from some time back that their engine
control system would allow the vehicle to run in limp home mode without
coolant in the engine's cooling system. Of course I recall top fuel
dragsters run without a cooling system at all but they rebuild the
engine after every run or two. ^_^

I watched a show where the builder of some vehicle decided to not use
radiator. Ran full out for probably less than a minute before it went
south.

Yeah ok.
Now I understand why some put you in their kill file.

Be interesting to see if he's got us both killfiled.

If so, I can go back to watching my gerbils have sex.
