1572 vs 1772 Radiator
I've seen on this forum many posts about overheating problems with the 782D and 1572. I myself, in the years I've owned these machines figured that it was the nature of the beast to run hot. Now that I have a 1772, I noticed it REALLY runs cool and as a test, I let it idle for a while to see if the temp gauge would creep up to hot in the same fashion as the 782D and 1572 always did. The 1772 stayed at the bottom of the temp gauge after extended idling. If I don't bump up the engine speed on the 1572 or 782D to almost mid throttle, I can be sure the temp would creep to the hot zone on the gauge. While looking for differences between them, I noticed the radiator on my 1772 appears to be larger. This may provide enough added capacity to keep it cool the way it does.
Now if you look at the radiator from my 1572 take a look at the size it is, and notice the size of the top tank. IMG_3503n.jpg Take a look at the radiator from my 1772, notice that it is bigger and the tank is bigger. IMG_3502n.jpg Is there a way to increase the cooling capacity of my 1572 radiator to match that of the radiator in my 1772, short of trying to locate a 1772 radiator which is probably impossible to find?

I didn't realize they had two different rads in them. Never looked at my 1572 and 1772 while comparing them side by side. Learn something new everyday. I do know they added the fan shroud extension to aid in cooling to some of the 1572's. My 1572 has it. I've seen them without it as well. Boy Frank, I can't think of any way to increase cooling capacity without putting in a larger radiator, which as you stated, would be impossible to find from a donor 1772. Curious to see what others think. Now I'm gonna have to go out and look at the supers and compare rads........

I have not had a problem with overheating on mine yet. They will go up to the right side mark (170*) and then you can see the thermostat open and the temp drop.
I never noticed the difference in size but the 1772 is about 2.25" and the 1572 is about 1.5". I learned something new today. The 1572. 1572 Radiator.jpg The 1772. 1772 Radiator.jpg

I thought and assumed that they would have used the same radiator in both models. Checking out part numbers for radiators between the 1572 and 1772....
782D, 882, 1512 & 1572 Radiator = KB19488-72060 1772 Radiator = KB19498-72060

I echo Todd as far as the overheating issues. I, myself haven't noticed any problems.............yet.
I wonder if the 1782 has the same sized rad as the 1772?

My guess is the don't get as much air flow as the 72 series do. I'll probably pull my radiators out this fall and have them cleaned at a radiator shop. They are probably getting crappy inside.

I was searching for the radiator thread that I started. In looking through the posts above, I noticed Oak said he never had an overheating problem with his tractors. Now I've had over heating with both my 782D and my 1572 but not my 1772. Looking at Oak's post, I noticed the pictures of his machines showed he did not have the extension for the fan installed on either machine. I did not have it installed on my 1772 and it did not overheat either. Is it possible this fan shroud extension could be contributing to the gradual overheating on my 782D and 1572?
Oak, what do you think?

Does your 1572 and 782D have the insulation on the hose that goes across the top of the engine? My 1572 had a overheating issues years ago and I noticed when it started, the insulation had fallen at around that time. I put foil tape on it and was cool as a could be. I noticed Todd’s has insulation.

Frank, I dont think any of my diesels have the extension. I have not mowed with any of my diesel machines either. When do yours overheat?

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
