G52000 temp gage

[Smokeless]

Just wondering if anyone retrofitted a temp gage on G5200. If so I would be interested and appreciative for info. Thanks

Your factory one is in-op?

Would imagine adding aftermarket be easy. Could perhaps use factory sender?

I suspect the factory gage is faulty, engine seems to run a little high, but I am not sure what is normal. Just inherited the machine. Believe I will drop by kubota dealer and price one. Thanks

I suspect the factory gage is faulty... I am not sure what is normal.

I actually have a G5200 with factory sender. There are 3 lines on it.

• Below lower line is "COLD"
• Above upper line is "HOT"
• Everything in between is "NORMAL"

Perhaps this helps you understand what is 'normal' range.

Beware, the D600 engine is a little large for the radiator. Everything needs to be working at top efficiency to keep the engine cool.

• Antifreeze (Proper mixture to be able to move heat)
• engine cooling passageways (clean-- no rust)
• waterpump (antifreeze flow)
• radiator (clean-- no scale)
• fan (airflow through radiator)

Any of the above can weaken the entire chain.

My G5200 used to climb above the upper line after mowing over an hour. (90F ambient air)

I did the following:

1. cleaned the INSIDE of the cooling system
2. changed leaking waterpump
3. changed hoses
4. removed radiator and used garden-hose to rinse inside in BOTH directions
5. Fill/flush cooling system several times - distilled water until clear
6. blow out with leaf-blower between flushes

Now, my temperature gauge goes above the upper line ONLY if the airflow thru the radiator is impeded. After shutting down and blowing the chaff from the airflow... the gauge is back to normal whilst running.

Believe I will thoroughly clean and see where I am. Replacement gage avail, little over $300.00 I do not use the mower routinely, Dad bought t new in mid 80's, I just dont want it to be parted out and the engine is still strong.

Run Evaporust in the cooling system for a week then flush:

Preferred method for flushing rust from engine water jacket?

For an engine still installed in a car. I've used some of the flush related products, but have been concerned about leaving them in the cooling system too long ( concerned they might be too corrosive and damage gaskets.) Now I'm starting to wonder if white vinegar could be an option? Anyone ever ...
