Cat Radiator

Copper radiators work just fine .. Cat have offered, and used - all copper, copper & brass, and steel cores - over the decades, and all perform satisfactorily if used in the conditions for which they are designed.

You don't want to use a copper core if there's a lot of potential sandblasting, such as high speed work, in dry sandy soil conditions. A sandblast grid assists with reducing sandblasting, but a steel core is needed to fully resist sandblasting.

Copper has a much higher thermal conductivity, a higher resistance to corrosion and a resistance microbial growth than steel. However copper is much more expensive and is more prone to theft than a steel radiator.

The thing that has me puzzled, is why the steel core is three times the cost of the copper?? It should be the other way around??

[quote="Catman"]Ozdozer I think I have the Answer 😊 Go and Buy 2 Copper Rads, then go directly to a Scrap Yard, and sell said Rads as Scrap new Copper, then use funds raised at scrap yard. and go and buy a new steel rad, you should even have some extra cash from the Scrap trade in of the Copper rads 😄 ,,

There has been reportings of people / gangs removing the main telephone system cable from a city supply 😮 the TV said they must of used heavy equipment like a winch tractor and big trucks 🙄 , the sale of High Voltage Electric Bolt Cutter Type insulated to 10,000 Volts, has been on an increase, and gangs are actually cutting through 600 Amp house supplies and robbing the cable, due to the high cost of copper LOL..

If your car is stolen, then you might find it down the next street, Minus a Radator 😄

When I worked in a big engine rebuild shop on the south side of Oklahoma City, some crack heads cut the chain link fence with a pair of rusty dykes (found them laying on the ground by fence). And then all the electric cables that run 50h.p. electric motor on all the big coolers with a pair of rusty scissors. After they cut the cable they sat in the back of the yard during the night and shot up with drugs (found the needles on the ground) and had a wire stripping party all night long using the scissors.
They caught them down at the local scrap yard down the street about a mile 2 days later after we reported it to the police.

About 20 years ago I made the mistake of putting a steel radiator core in my 7U. It was a big mistake, it set in motion a whole series of cooling system problems that plauge it to this day. It did not cool near as well as the original and I am in a cool climate. Of course the oil cooler was bypassed so it did not have that cooling capacity.

A few years ago I was able to pick up a 5T with a toolbar blade and 44 pump that had no radiator, the tanks must have cracked because they did not come with it. It did come with a good full width brass core. I put that in the 7U and it cools real good now. I got the whole works for less than the price of one of those copper cores I am sure.
