[I'm definitely not an experienced mechanic, but I have changed a head gasket before, but that was a LONG time ago. Remind me of any gatchas?]
My Kubota G5200 HST (3 cyl diesel mower) is overheating. Seems like a common problem. Only seems to overheats under load.
Anyway, I DID see air bubbles in my radiator. AND it uses water (but haven't noticed any in the oil). AND I can see some faint smoke coming out of the radiator when still cool (just after starting it up). So I am about to change the head gasket.
Wondering what else to do while I'm in there doing the head gasket. Already thinking about the following:
Any other ideas?
I have noticed that the coolant drain cock on the block is rusted shut. Wondering if the cooling passage is also clogged. Don't know how to check.
Does your G5200 have a radiator fan shroud? Mine doesn't, but the Kubota Parts Site shows one (search G5200, click open, go to Cooling System / Radiator and it's part 110, #15852-72330). They are about $55. Wonder if it would fit mine and if it would help.
Also, does yours have an coolant overflow bottle? Mine doesn't, but it has a tube coming out of the neck of the radiator. So I just wedged a aluminum can in the frame and stuck the tube in the can. Don't know if it helps.

- Fan Belt
- Radiator Hoses
- Exhaust and intake gaskets and bolts
- Valve adjustment
- Head resurfaced
- Coolant system flush and, obviously, new coolant.
- [Already had radiator boiled out not long ago]
- Any sensors that should be replaced?
- Anything to check on water pump?
- Can you reuse the head bolts? (Service Manual (pg 1-53) doesn't mention replacing them, so I assume reuse is OK.)
