Warranty issue dispute with Kubota - Advice anyone

[Diggin It]

Not disputing that, but it doesnt make much sense to me. Temp senders are just resistors that vary their resistance based on tempature. It shouldn't matter if it's in liquid or air. Liquid transfers heat way more efficiently so I could see it reading if the temp sender was being cooled by the outside of the engine or something & the hot air couldnt heat it up fast enough. I'd assume there wouldnt be enough cooling to drop the sender that much though.

My inner nerd wants to understsnd why it doesn't behave like I think it should.

Suppose ... just suppose that there isn't enough coolant to circulate properly and whatever is in contact with the sensor isn't heating up keeping it cool below the sensor threshold.


Submitted for your approval or at least your analysis.

The OP clearly isn稚 very mechanically inclined. That doesn稚 make it Kubotas fault. Insurance pays for screwups that were no fault of theirs. Warranty doesn稚.

Dead Right, but he wants it to be and wants Kubota to be responsible for His lack of knowledge and stupidity. The less they know the more they want to blame others.

I side with AV. Looks like a design fault to me.

I would want to see the "tube" that failed, how it failed, and how difficult it would have been for the manufacturer to protect it. Tractors will ride over sticks...design accordingly. No one else has ever reported such a tube failure that I am aware of ?WHY?

This is not a "cheap" LS like I have, but a top of the line (with a price to match) tractor. It is TOTALLY unreasonable to need to check the level of the coolant every time you use the tractor by opening the rad cap. I look a the level in the overflow tank.

I appreciate all the input. I am still a bit hopeful that they will cover it. Told me they are working on it. The dealer service guys agree with me. They are trying to get Kubota to cover it. Hope to know by the end of the week. I already approached them about a trade in for it and let them deal with the problem at their much lower cost point than me doing it. Just a question - Why don't engines read the oil temperature instead of water temperature?

I like the ones saying, check the radiator before every use. I mean who really does that? Our son has one tractor that's used every single day of the year 30-45 minutes per day moving round bales. I can't imagine him checking it everyday.

I agree that most of us don't do the simple checks before each use.
I have to remind myself that checking fluids before operating the tractor takes less than a few minutes.

Oil temp will change slower then engine temp, it also has a broader operating range then the coolant does so having a "target" temperature is difficult.

The idea is that overheating from loss of coolant should be noticable by the operator due to smell or visual cues such as steam or leakage, otherwise the gauge is the indicator.

Companies could add a lot more sensors and people would still manage to cause damage.

The best warning indicator is(should be at least) the person operating the machine as it can adjust for more criteria since there should be an operator present when the equipment is being used.

. . . Just a question - Why don't engines read the oil temperature instead of water temperature?. . .

Would want to monitor the highest coolant or oil temp. The highest coolant temp location is clear, near the return flow to radiator. Coolant flow typically is jacketed flow surrounding the oil gallery flows. Measurement location for oil temp is not quite as straight forward as for coolant temp.

Not clear what went on here but coolant temperature is reliable means of monitoring engine temperature as has been used for years in automotive, agrcultural, and industrial applications.

Huh - my brand new Taco Wagon( Ram 2500 Power Wagon) measures everything. Engine coolant temp, engine oil pressure & temp, transmission oil temp, engine coolant level, tire pressure, front/rear differential oil temp, inside/outside air temp, remaining useful life of engine oil. And it responds to voice commands - even naughty ones. Won't even get into the mapping, entertainment, telephone, GPS or POI systems. Needless to say - a person will learn to pull over when they start "pushing the buttons". OR you can end up in a place, not of your liking.

SO.....when the on-board computers fail, as they all will eventually, there is a "limp home" mode so it can be rebooted and/or repaired.

Why do you call it a 'Taco' wagon? When I think of a taco, I think of Taco Bell and candidly, I despise that fast food junk. All they do is give me the squirts and with TP as it is today, I prefer no squirts.:laughing:

All those electronic gizmo's are there because the average person it too lazy or lacks the ambition to check them, themselves. Like the TP monitoring deal. Too lazy to check the air pressure so the government mandates them. I removed them from my wife's Burb and my Ford. Useless unless you are really that lazy or stupid or maybe both, who knows........ and when the batteries poop out and they do, the replacement senders are expensive.

Whatever blows your dress up. Don't lift mine, at all.

Is it important?
