    L185DT - Overheating - Think I've tried everything

    Nope, no problem. It was $80 bucks, and that's in Wichita, KS. Guess there is only one radiator shop left in town that will service them here anymore. Before I went there, I did stop down at my local Kubota dealer and check with their parts dept., just to see what a brand new one cost (in case...

    L185DT - Overheating - Think I've tried everything

    Ooops! Yes, those should be reversed. Good catch, thanks. I haven't had a radiator serviced before, so I don't have anything to compare with, but the thing came out looking brand new!

    L185DT - Overheating - Think I've tried everything

    Back with an update from yesterday (2-28-16). NO OVERHEATING !!! Mowed a lot longer this time (1hr) with just H20, and then 50/50 mix. First, tested my temp gun inside like suggested. Accurate. Shot a couple of places inside and it was reading 68 deg, just like my inside thermostat was...

    L185DT - Overheating - Think I've tried everything

    Update from yesterday 2/28/16. Hooked back up "new" radiator and filled it up with distilled water then took some temp readings as suggested. Took readings at 3 places. Top rad hose, bottom rad hose, and engine block (right next to the alternator). Took 2 sets of readings. 1st set after idling...

    L185DT - Overheating - Think I've tried everything

    Yeah, I've learned a lot about my tractor the last month or so. I think I need to flush the block out better too (working on it tomorrow). Now that I've got the radiator off, I'm going to stick a hose in the top inlet on the engine where the top radiator hose hooked on and run some water...

    L185DT - Overheating - Think I've tried everything

    Just happened to have the radiator out in my truck. Taking it back out tomorrow to put it all back together and see what happens now that I've had it cleaned and rodded (even though they said it looked pretty good). Took some pics of the radiator cap to see if it tells you guys anything. Looks...

    L185DT - Overheating - Think I've tried everything

    I'm using a genuine Kubota cap, specific to that tractor. I get all my parts from an authorized dealer. In fact, one of the first things I tried a couple of years ago was a new cap. So my current radiator cap is only a couple years old. If my memory serves me, that seemed to help, a little back...

    L185DT - Overheating - Think I've tried everything

    Okay, I have an update...pulled the radiator off and brought it back to town and had it taken apart and cleaned and "rodded." More in an effort to rule that in or out. The radiator shop said that it looked pretty good and they didn't see anything wrong. Now the radiator looks brand new. Money...

    L185DT - Overheating - Think I've tried everything

    By "dump coolant down the pipe" do you mean the opening on the top of the motor that the top radiator hose was hooked to? Sorry, just want to make sure that I understand 100%. I'd hate to create another problem for myself :D I did spray it off with water from the garden hose after I blew it out...

    L185DT - Overheating - Think I've tried everything

    I will try bleeding the air out of the system, then take some temps. Now, I did put straight vinegar IN the radiator when I pulled it off the tractor. I plugged the bottom hole where the bottom hose fits on with a rag, and let it sit overnight, then flushed it all out with distilled water...

    L185DT - Overheating - Think I've tried everything

    What do you mean by draining the whole system? I opened the drain on the front of the radiator, and the other on the right side (drains the engine block I would guess). Plus, after that, I pulled off the whole radiator and soaked it overnight in vinegar to try and clean the inside of it. Don't...

    L185DT - Overheating - Think I've tried everything

    From what I understand, this model (L185DT) doesn't have a thermostat, or a water pump. It uses thermo-siphioning to cool. Am I wrong?

    L185DT - Overheating - Think I've tried everything

    Hello, New to posting to the forums. I'd consider my skill level as beginner as far as technical skill(s) go. I do regular maintenance myself as far as fluids and filters though. I've had the tractor about 12 years now. I bought it used, and am the third owner. Tractor has 2000 hrs on it. No...
