    Default BX Radiator Drain Plug Removal

    I performed my first radiator flush and fill today on my BX24 and had problems with the radiator drain plug. Once I finally found it, I had no easy access to it. I thought it was going to be a bolt type plug but it was a rubber cap with a pinch clamp. My question is - has anyone successfully removed the plug and put it back on? What tool did you use to remove the plug?

    I searched here on TBN after I couldn't remove the plug and found a few posts suggesting to remove the lower radiator hose instead. This is what I ended up doing, hopefully enough drained out of the radiator during the flushing process.

    On a side note - I went to my dealer to pick up some antifreeze and all they sell is the regular gas engine type. Ended up finding some Fleet Charge diesel antifreeze at Tractor Supply.

    Sorry but I have to ask. Is there a difference between gas and diesel engine antifreeze?

    You bet, and I'd have to check my memory banks, but I believe it's mostly cause of the wet sleeves in diesels.

    edit; memory banks says google "Cylinder Liner Cavitation"

    Like Will said yes.

    Some, possibly all wet sleeve engines are sensitive to the type of antifreeze used. Not sue if it is due to the seals used on the sleeves as well as preventing the cavitation that Will also mentions. I have seen two Case engines where on both of them the block was eroded around the seals and allowed anti-freeze to mix with the oil. The results are expensive.... In both situations the lower seals went so there was no compression getting into the water jacket to give any indication of the failure.

    Had the same difficulty accessing the drain tap due to the clip instead of what the manual shows to be a threaded cap. I drained and flushed the BX24 by removing the lower radiator hose and was feeling pretty pleased with myself. Then got good advise in another thread from Roger that was not available in the owners manual. I did it again also removing the block drain - big difference in the amount of coolant that came out.

    Thanks Tom, your post is the one I read to drain from the lower radiator hose after I couldn't access the radiator drain plug. I should have read it slower because I skipped over the part about the block drain plug. Like you, I think I will drain it again. I know I didn't get 3.3 quarts out when I drained the old antifreeze, drained the radiator flush and drained the straight distilled water.

    Yeah, something suspect about a kubota dealer that wouldn't be more than happy to sell you some genuine Kubota coolant...
