    Default Bolens G174 heat warning light

    Since I bought the G174 three years ago the cooling system has never uttered a burp. It was as if the thing didn't have one. Then while I was picking up a little cherry tree in the woods with the dump box, the overheat light winked on faintly. I shut off and checked the coolant. All fine, and the engine wasn't hot to the touch.

    Tinkering involved blowing out the radiator fins, removing the sender and cleaning it, cleaning the connection, draining the coolant and adding new, and a installing new fan belt.

    Suspecting a head gasket I trailered it to a local machinery dealer. The mechanic who looked at it said it wasn't a head gasket and suggested the fan belt. At 32 years of age (original Mitsubishi belt) it was due for replacement. The water pump does not appear to leak, and I think the thermostat works, though I'm not sure.

    So all is maintained on the cooling system, but the light still comes on faintly, more often than not. I suspect the sender is shot.

    Advice? Source of sender?

    Thanks,

    Rod

    Buy or borrow a temperature gun, point it at the area of the water coming out of the engine to the radiator and check the temperature. This can tell you what the real temperature of your engine is.

    The Bolens G174 mechanicals are the same as an an Iseki TX2160/TX1500F - built in the same factory, same HP, gearbox, axles, diffs, pumps, linkage etc- the only major difference is some of the early series to maybe c.1981 use a K75 2cyl Mitsubishi engine whereas the later Iseki's mainly use a KB3 3cyl Mitsubishi.
    Here's a list of parts suppliers in the USA which may assist (which I have copied from other sites) -unfortunately as I'm in Australia (where I use only Iseki dealers as there are no Bolens supplies) I have no recent experience with suppliers in the USA:-

    Bolens G154/IsekiTX1300F

    Default Re: Bolens G174 heat warning light

    I have a TX1300F, and I briefly had an issue with the warnings light. I ended up replacing one of the lights, and my issue was coming from a power surge at the voltage regulator. The square box behind the dash where the back of the turn signal is located. It was allowing my tractor to charge at around 18volts, and wrecked my battery, blew my headlights, and my indicator bulbs. I have seen the temp indicators available on eBay if that is the issue. There is a guy in Oregon who I have bought parts from, and usually has parts for the engine that you have. I would give him a call: Small Import Tractor Supply

    Thank you for taking the trouble to compile this list. I'll save it and refer to it as needed in the future.

    [QUOTE=Rod in Forfar;3289510][QUOTE=MBTRAC;3288332]
    Here's a list of parts suppliers in the USA which may assist.

    I spent an amusing afternoon on my computer/phone, calling my way down the list. This thermo switch is unavailable in North America at the moment. In Japan they want $174 US for one. Ron in California was very helpful. He suggested a Yanmar thermo switch uses the same threads and runs at the same voltage, so it will work, and it's priced about $45. He ordered four and will send me one when they come in.

    This gentleman seems very knowledgeable about the G174. He told me that he sold his G174 for a step-through kubota and soon regretted it. But he did mention that, with loader, he got $8000 US for it on the sale.

    The list above showed the business as

    Homestead Tractor
    22311 Bear Valley Road
    Apple Valley, California 92308 Has stock for G174痴.

    BUT while the telephone number located Ron, the emails were lost in space, and the company name seems to be Justtractorparts.

    Telephone: 760-240-1062
    Fax: 760-240-1126
    Email: sales@justtractorparts.com

    One other thing: during our conversation Ron told me that the sender on the KE75 fails because the ceramic inside the part that goes into the engine cracks. From that I can infer that one could almost cut the wire and rely on one's nose in the future, because there isn't necessarily anything wrong with the engine for the light to misbehave in this manner.

    I'm still hoping to get a Yanmar sender and bolt it on, though.

    You can also buy a temp gauge and adapt it to fit in the cylinder head. I believe the hole is a standard NPT, or at least an NPT will thread in and seal with one of the gauges I bought and used. The problem with the temp gauge is that you'll lose functionality of your warning light unless you get creative with a sensor that actuates off the electric temp gauge signal. I ran across a circuit board, I think from "Jegs Performance" or something like that, that you can tie-in to the gauge sending unit and adjust it to the temperature you'd like it to activate the light. Recently, I just extended the piping off the pump to install the gauge sensor and keep the original temp switch to activate the light. The circuit board didn't hold up the greatest on the tractor, but that's mostly due to the way I installed it.
    One nice thing about being average is you're not alone.

    "Ron in California suggested a Yanmar thermo switch uses the same threads (NO!) and runs at the same voltage, so it will work (NOPE!), and it's priced about $45. He ordered four and will send me one when they come in."

    The Yanmar thermo switch arrived today by Canada Post with about $17.00 due for brokerage fees. Fine.

    I removed the old switch and squeezed the much larger Yanmar unit into the same space, taking some time to get the 27 mm wrench in around the fuel lines. It wouldn't tighten up to where anti-freeze didn't leak, so I eventually removed it to discover the Yanmar threads are coarse and the Iseki threads are fine. It wouldn't work. I took it out, screwed the old one back in, and grinned when the familiar light winked at me when I started up.

    Lesson learned. A bad temp sender is better than a new one which makes the engine leak fluids.

    Last weekend while waiting for the part I bought a 2005 kubota B7510 with 210 hours, so I won't have to rely as heavily on the Bolens now.

    I may have to post a change-of-address here for the Kubota forum, but so far I still prefer the sound and feel of the Bolens twin diesel. It's like a heartbeat. The Kubota? You strap yourself to the seat or slide out of it. The engine doesn't say anything to me, though it mows up a storm with a 5' belly mower. I seem to have a lot more arthritis since running it, but that may be the weather.
