Kubota Recall - Be Aware!!!!! NOT SURE WHO OR WHAT YEARS ARE EFFECTED...!!!!!!!!!!!!!

[Howling]

Got my replacement. It is clear. Instructions reference a blue dot on cap to verify the cap was checked and OK.

Mine also has red dot. Wonder if they are still having molding problems and cleaning them up at factory.

I'll pull it off later today and have a look, just I haven't looked yet and not sure how you check for a blockage, will probably be obvious when I see the part.

Just look thru the hole where the hose slides onto the nipple, you`ll be able to tell if its got any debris in there. If it does have any debris, it will look like plastic shavings inside the hole.
Best to use a good source of light, shine it into the cap and then look at the other end where the rubber hose slips onto it.

I would run a proper size drill bit thru it regardless just to make sure its cleared. I would also blow it out with compressed air too!

Dont depend on the painted dots... my replacement recall cap also has the blue and the red dot and mine was plugged with plastic debris.
I`m starting to think most will be ok... always been my bad luck to get the short end of the stick with anything...lol

.....BUT i would check those replacement cap`s regardless!!! Piece of mind!

OK....just to make sure I understand....

Instead of just sending instructions on how to clean up the hole in the overflow tank cap so that the old caps would work right, Kubota sent out whole new caps that had the same problem as the original caps. But they forgot to include the instructions on how to make them work right....

Is that it?

I just went out and checked my BX2370. Very quik and easy. Like 10 minutes, tops.
Remove hose from overflow bottle cap. Remove cap. Gently insert 11/64th drill bit in nipple, turn it in manually until you can see the tip of the drill bit in the center hole on the underside of the cap. Blow out any debris out of nipple. Top up antifreeze in overflow bottle, if required. Instal cap on bottle, and re-install overflow hose on cap.
Happy tractoring.

LOL.... you`re absolutely correct...!!!!!!!
Kubota probably thought that people wern`t smart enough to figure it out on their own, so they wasted alot of time and resources instead.

Exactly that!!!
Happy tractor, happy owner!

The issue being, the steam escaping from the hose could burn you (hence the recall) and if you didn't notice it, you would be low on coolant when the engine cools down and cannot suck back the coolant to replenish what it vented. That could cause you to run out of coolant and roast the engine.

I'm still not tracking this discussion...

This is the yellow cap on top of the burp tank? Yes? It can have plastic debris blocking the passage to the hose? Yes?

So, any over-pressure is inside the burp tank. It won't blow off the hose - that's open. It won't vent steam - it's plugged. If the pressure is sufficient it might blow the cap off. W/enough vibration that might cause coolant to splash out the top of the bottle. If enough is lost, when the radiator cools and "inhales" it might aspirate some air. Probably wouldn't fry the engine - but it would potentially, long term, lead to some corrosion.

That's (my understanding of ) the burp tank's function - it allows purging air from the system. It lets the system run fully-charged with coolant and stay at a constant pressure once hot. Also compensates for any slight coolant loss and allows inspecting level w/out taking off the radiator cap.

During normal operation the coolant level in the burp tank doesn't reach the top. If it did, and the cap was manufactured properly, it would be running out of the hose. Running one that's plugged makes it even less likely that there will be coolant loss.

Barring a total rupture of the burp tank I'm not seeing any catastrophe here. Potential scald danger, yes. Engine damage, probably not - unless the puddle and steam from a burst tank are ignored through multiple use cycles.

OK, educate me. What am I missing?

thanks,

As I understand it, the cap of the burp tank has a hose barb on it, the Overflow hose from the radiator goes to the Barb on Burp tank cap.
That barb is supposed to connect to another barb for the dip tube that goes down to the bottom of the burp tank. The problem is that the barb that the hose from the radiator connects to is blocked, thus if you get pressure in the overflow hose from the radiator, it could blow itself off of the burp tank lid and hose you down with steam if you opened the hood while it was venting.

I don't believe that's correct. The overflow from the radiator cap goes to the _bottom_ of the burp tank. That's how it's able to draw coolant back in when it cools w/out aspirating any air.

The barb on the cap goes to an overflow hose that is open at the bottom and drains "overboard". At least that's how it is set up on my BX and GR.
