Radiator - YM1700

[SailorBob]

Since the board has been so quiet lately I have a question. Since rebuilding my engine I have determined that the engine still wants to overheat. I am not going to take a chance on running it hot again. I have replaced the temp guage twice so I am confident that the guage is accurate. I had it cleaned at a radiator shop and after he cleaned it he told me i should have it re-cored. I wish he had told me that before he cleaned it. Anywayn it looks like i am going to either have to have the radiator re-cored or buy a new one. It will cost about $200 to have it re-cored. A new one is around $300.

Does anyone have any opinions as to which option to choose? I am not exactly sure what all gets replaced with a re-core job.

Don't know what type tanks your radiator has (metal or plastic). With the plastic they the tanks off and mount on new core, works well. With the metal they sweat the tanks off and resolder them on the new core. In either case if it is e good radiator shop it should work well and be problem free. Good luck

Just my opinion Bob, I would go with the recore if your tanks are good.is that 300+ shipping ?

How hot does it get?

Recoring might be a better bet. I replaced the radiator on my 1500D. It fit ok, but was not identical. There were no clips to hold the screen and no easy way to add them. The drain was different and required a modification to the tractor. I noticed the original had some baffling in the upper tank that was missing in the new one. Don't know if that makes any difference in operation, tho.

I had the radiator on my YM135 recored when it was rebuilt. Any good shop can recore a radiator and make it like new, or even better than new. Mine was also around $200 to be recored, about 100 less minus shipping for a new one. With fuel prices the way they are, I am saving every penny I can. Good luck on the rebuild Mike

When it gets close to 230 I idle it down to allow it to cool. It stayed between 210 - 220 without the brush cutter. I am pretty sure it must be some kind of flow problem. Just as an experiment I changed the cooling mixture to about 10% (antifreeze) and it ran about 15 degrees cooler.

The OEM Temp sending unit is set to turn the light on at 248 degrees and off at 238 degrees. I have had a lot of customers that have added a water pump to the YM1700 and all of them said that it made a big difference.

At least I know that I did not ever run it hot then. I wonder if my money would be better spent on the water pump kit or the radiator? We have very little cool weather down here. A 20% antifreeze mixture is probably safe in the winter. It rarely gets below freezing. If you are interested in selling me a water pump kit PM me with details.

Thanks Danny

if it were my tractor and I had not taken care or the radiator yet I would do both, water pump and radiator at the same time. better safe than sorry, why not spend a little more money and be done with the whole deal.
