my fix to overheating tractor

[reddragon]

you know.....black bart is right.....you need that cooler pulling fresh air and pushing the heat into fresh air.....an air cooled engine isnt going to like extra heat added to the mix at all...if you had the cooler behind the grill [ i know its hard because of the hood flips up] then ducted the heated air to the side so that it has nothing to do with the engine cooling...or at least duct it where it is so the heat exits the engine compartment :frown:

When you posted how hot your oil was with the cooler on I thought you must have put on a really small cooler because it was not cooling like it should.

After seeing the photos I see you have a large cooler but it can't work properly the way you have it installed because you are just recirculating super heated air.

After the fan blows through the oil cooler it just loops around and goes through again.
If you cut a large opening in the hood install a grill like they have at Lowe's and build a fan shroud so it must pull outside air then you will be blowing cool outside air through the cooler instead of recirculating the hot air under the hood.

Also the hot air coming out of the oil cooler is going into the cooling intake for the engine and making it run hotter.
My 180 JD has a divider under the hood and it pulls fresh air instead of hot air from under the hood you could do something similar.

You could pull air in from the top of the hood for the intake for the engine.

If I put a oil cooler on my Z Trak i won't have these problem the engine is out in the open lots of fresh cool air.

I guess you could remove the hood on your tractor it would work much better with the hood removed.

Bart I agree, and am thinking about it. I did note previously that my fan mount is not so good and blanks off the center of the cooler, I am thinking of a spider man "web" made out of .060" wire. . It might really help along with better ducting in and out. Motoman

Red, yes, see response to Bart below. So you want me to keep "tinkering?" Motoman

That smug mug site has a pic showing about 260*F- after an hour of operating in very hot ambient temp, Kohler says anything under 300*F is doing very well; I wouldn't lose any sleep over whether or not the oil cooler is adding heat to the engine because of where it is located in the air stream.
Kohler shows an oil cooler for all its engines as an aftermarket add on, and there is also a remote oil filter mount-thinking that you could buy both and mount the cooler right in the air intake....

Briggs told me that if I added their oil cooler to the ELS the warranty would be void-another reason NOT to like Briggs and Stratton.

Briggs says not to, Kohler says go for it if you wish, my kinda Company.

Robert, "what smug site"? Is it Kohler or BS that says 260F after hours? As noted I am not hip about the tractor / mower world , but I thought once at Sears I saw a rig with a "gold star" or "gold seal" Kohler for some extra dough. No one there could tell me what was so great. Regards Motoman

motoman,
betsy-tom (betsy-tom)'s Photos | SmugMug

You have to go all the way down to the bottom and look for the 'Cub Cadet' place, an awful lot of pictures showing a new GT2000. I think the temp pics are on the last or second to last page; this Cub is one nice tractor, .....

But man do you have to feel sorry for the people who bought that motorhome

 

[Black Bart]

Motorman are you getting you oil temperature when it comes out of the engine or are you measuring it on the way into the engine after it has been through the cooler.
Their should be a big difference.
i drove a Sprint car and it had 2 gauges for oil temp it had oil IN and oil OUT
Oil out is the important temp but if the oil in is high the cooler is plugged and we would clean the dirt out of it.:thumbsup:

If you are seeing 300F on the oil in the oil out would be even higher.

How is the temperature of the oil going to increase once it is inside the cooler?:confused2:
