Are you absolutely sure about that?
Yes.
But the the way I imagine, every car should have at least two stages of cooling circulation, right? Well in a sense you are right. Zaz for example only had air cooling system. Liquid cooling is for engine block and airflow to cool radiator. Without necessary transfer of heat engine overheats eventually, and head cracks, burns through on some cases, you loose compression and etc. Usually it's fatal. Laser welding is probably only good option for new cars, but in cost a fortune, but for Ural engine you could probably do that on Your own.
Water pump is most important here, if it fails then water won't circulate and no matter how much airflow you have it will overheat in minutes and cause catastrophic failure.
In that case, overcooling certainly shouldn't happen.
Why
? I wish. There is even thing called cold corrosion, not sure if it's right term in English. For diesel engine it's clearly an issue, be it Ural or Audi Q7. They need to reach operational temperature to have proper combustion as the have no spark plugs. They use temperature and compression to go boom. Cold air has different density and it might cause wrong compression rates, imperfect mix. Have you ever noticed idle shaking when car is cold? Some cars have air heaters in manifold so cold air is not an issue.
Diesels generate heat slower than petrol engines too so needed heat is partly wasted for warming up. Imagine what cold stream of - 20 C air can do to such large radiator like on Ural, it won't reach optimal temperature at all and it can start chocking.
There are so many factors that are affected by cold, even consistency of diesel.
Even for fan running, I think it CAN be turned-off (just aren't sure if from the cabin, or manually). Remember, Ural was designed with ford-crossing in mind.
Could be possible to turn it off manually, but it's controlled by thermostat.
And dust is a problem not only in Africa, but on unpaved roads as well, but that's probably not the case for Crimea
For dust there are filters, inlet pre-filters and so on. There is even external filter for rally cars, basically a mesh. This doesn't look like it.
Another thing that's highly likely, it's a thermal cover against TIs.
No, man. Exhaust is more important for that. Bonnet will still have signature on it, not to mention bottom of the car where heat escapes as well.
By the way I've seen them covers used in Canada an US.. on TV of course:D

By the way thanks for the video guys, well oath is an oath, if we take a look back, they weren't pro Maidan, they have never threatened Ukrainians or Russians in the region. Most of them are locals in Crimea as well. Was laughing hard when Alexander Vitko, commander of Ternopol refused to lay arms and said Russians don't surrender. He is ethnic Russian with ukrainian surname.
Idiots who do provocations are from AF and they feel that Russians are only harsh with words no real action was taken, there was no ultimatum, no one will shoot at them. Crimean militia might be less polite.
