Need some help- small anti-freeze leak on Deere 2305

[JB2]

Have you look also at the possibility of the radiator drain plug? Its on the right hand bottom of your radiator, white plastic wing nut style. You can partially see it in this picture just below the rad and above the hoses. Could be a little loose and let a few drip once in a while.:thumbsup:

Hi

I will have to take a look at this, and it might be a possiblity as well. I am not 100%. There was no anti-freeze leaking from the hoses or clamps so this might be a possiblity, will check tommorrow. Thanks Jason B

dItto on the overflow tube. I had a few drips from the tube where it connects to the fill cap on the radiator a few years ago. I pushed the tube onto the fitting alittle tighter and it stopped.

I am not sure if its the overflow tube thats leaking, the small leak was behind the right hand tire. About a dims sized. I am hoping its not something too serious. Take Care Jason B

JB2,

Have them put a tracer dye in the coolant to help pinpoint the leak. The dye fluoresces in UV light making it easier to locate.

Can you buy this tracer dye though stores such as TSC? The dealer was out today, and they sent one of their new mechanics out already to look at it, they could not find it... I might try and get this dye and try it myself.

Call your local auto store that caters to the professional mechanic (NAPA or others). Then again you might get lucky with your local Autozone, Pep Boys or whatever is in your neighborhood.

Here are a couple of examples from NAPA:

I do not recall seeing it at TSC.

Take a look at the weep-hole area of the water pump. Not the easiest thing to see, but its another possible area where a leak could originate. Mine failed at 150 hrs. Good luck.

If can't find w/ hose checks, etc. try removing the fan shroud and see if there are any bent fins. If there are, the fan has contacted the radiator and you could have a hole in the core. Had a 2305 w/ several holes and ended up replacing w/ 2520. Keep an eye on it - the temp sensor is only good for the fluid overheat. No fluid = no high temp = really bad things with lotsa zeros in the price tag. Problem is some 2305 flex-mount radiators is there is too much flex and if you hit something, the radiator flexes back right into the water pump assembly. Best of luck!

I had the Deere Dealer come out 2 weeks ago, and they did a Pressure Test and could not find a Leak. They looked at the Water Pump a bit and could not find anything. Blew snow with it a couple of times afterwards, no leaks. The Tempurature has been all over the place. Went out this morning and there was a small puddle of anti-freeze on the ground again. If its a crack in one of the hoses it must be hard to find or a location I can't see it. Took the 2305 out to the dealer this afternoon, I don't have time to mess with it myself but am a little concerned. I am getting the Dealer to check for bent fins on the Fan to see if theres a hole in the Core. I will get them to dubble check the Water Pump, where it seeps out... they might have missed something last time. The problem is, the leak is anti-freeze puddle appears on the ground but can't seem to find the leak. I am hoping that I don't need to pull the Rad or theres a hole in it.

Yeah, Its a bit frusterating but hopefully they find the problem. I am hoping its something small. When they did the pressure test the first time around, the machanic said the pressure was down a bit but nothing to be too concerned about, now it leaks a bit.
