Re: My JD 332

If you can mow tall grass for 3 or 4 hours without the temp light coming on, I'd say, "problem fixed!" There's a VERY good chance there's just a slight build up inside your radiator. That's providing enough insulation to prevent your coolant from getting cool and giving you a hi temp condition. Hopefully, the flush will solve your issue. Good Luck, Bob

Well I drained the coolant and refilled with flush and water per directions of bottle. I finished mowing the pasture took just under an hour no light came on. I went to park the mower turned it off and the mower started sizzling lifted the hood and fluid was spewing spraying from the overflow escape. Tube looked to be melted and hot.... I知 scared to do anything right now I知 hoping I just overfilled it accidentally and it was letting some out and the tube failed...thoughts

Re: My JD 332

As coolant, or whatever is in the radiator, heats up, it expands creating pressure in the radiator. when the pressure in the radiator meets or exceeds the rating of the radiator cap, (yours is probably 15psi) the valve on the bottom of the cap opens and allows excess pressure to bleed off. This is a "normal" condition..assuming the cap is not worn and relieving pressure to soon (like 5 or 10 psi).

Soo, where does that leave you...no place yet! After running for only an hour...or even 3 or 4 hours...the flush hasn't done too much. This is a chemical reaction that has to dissolve the corrosion and chemical deposits left from your antifreeze breaking down. It usually takes a few hours, (6-8) AT OPERATING TEMPERATURE, to do this...the clock doesn't start when you turn the key! And one more quick comment. When your engine is running, your fan is cooling the radiator. When you stop the engine, especially after working it hard, the heat in the engine transfers into the coolant making it hotter and possibly "boiling over".

Let the engine cool, remove cap, and check level. You want to see the level maybe 1/2 inch or slightly more below the bottom of the radiator neck. As far as the overflow tube, pull it off and blow air through it. If you can get air through, it'll be fine. Run the flush for the time on the bottle and even a few more hours. Cool, drain, fill with water (rinse), and run for another hour. You need to get to operating temp so your thermostat opens and "rinses" both the radiator and the engine. With just water, I'd try mowing and see what happens...maybe a light, maybe not.

I've been following a post on a forum...maybe this site, maybe another... about a 332 overheating. The guy is just starting to troubleshoot but another poster commented that he had a new water pump, thermostat, radiator rodded, and STILL had overheating problems. His closing comment was that the system wasn't designed correctly. I don't buy it! I'm thinking more like a shabby rodding job and he still has a bad radiator.

Mow for a bit with plain water and keep us posted! Bob

Went out and got a new hose since this one pretty much melted. Checked level which was below seeing it so I added 250 ml to get it back to where it was suppose to be. Mowed for a while,..maybe 45 minutes 90 degrees here and I知 technically all done I was just running the pto through all the hay from the pasture drove it back parked it and watched it start to go into the overflow but not far then leak around the edges. I wonder if the flush/ water has a lower boiling point then coolant. Either way I値l run this next weekend for another 3-6 hours then do the next steps in the flush. When I checked the level I also checked the temp it was at 170degrees f

Antifreeze does 2 things it does prevent freeze up it also prevents boil over. 90 degree air coming thru a radiator won't won't have as much of a cooing effect as say 70 degree air take it easy on the old girl if you were weed eating in 90 degree heat you would overheat as well. Try mowing at a cooler time

Re: My JD 332

Just a quick update.... still doing the flush. still overheats at about 3 hours and yes its been hotter then hot so im kinda not to worried right now. When the light comes on i park like normal i can hear the fluid boiling inside and the last couple times fluid has exploded out of the radiator cap. Im starting to wonder if the cap might be faulty.

Either way im hoping this weekend will be cooler

Dr, Replace cap first. That could be your problem...or not!... but you won't know until you replace it. Bob

Re: My JD 332

I finished the last steps of the flush and had new coolant in the radiator, replaced the cap with the new one and tried again. Things were different this time I made it 2 hours without the light coming on temp outside was only 82. The new cap didn't let things spew out the top and seemed to help cool things down much quicker. Unfortunately it seems i might need to have the radiator boiled and rodded.

Well that's progress but still stinky that you may have to have the rad re-worked.

I'm having the same problem with my Diesel truck. I need to clean it and go from there. $400 for a new rad is not in the budget!

Been driving Deeres since 1974, Dodges since 1984, and Davidsons since 2004. Love my wife and kids I'm a blessed man.

agreed called my friend who is a farm tractor repair man he gave me the name of a shop that does radiators... have it scheduled to be boiled rodded pressure tested and painted next tuesday... if this doesn't work i guess the temp gauge, but even he said it doesn't sound like that.
great part is the shop only said $110 to do the work
