1700 temp light

[Gizmo36]

I had 50/50 in it, in the winter that was good to -34 .then when I fix the head I added some water . it was at 0 . to day I put more water it is at 10 above.don't know if that would be 30/70 mix are not.

I have been thinking 30/70 mix that would be 1 quart of antifreeze to a gallon of water.Is that right or am I still wrong .And dose any one know how cold that would hold in the winter.

</font><font color="blue" class="small">( 1 quart of antifreeze to a gallon of water )</font> would be 1 quart in 5 total, or 20% or 20/80. Never trust the mix in terms of deciding protection level. Spend $5 and buy a tester.

I have a tester I was just trying to get the 30/70 thing right.

I had the exact problem. First, I replaced the sending unit with an after market one from one of the most recommended dealers on the internet. He said it was the same as the 2000 but the Light still came on. I had a new radiator core put in and flushed the block. The light still came on. I put on a used sending unit from a 2000 (because several dealers said they were the same). The light still came on. Then I replaced the sending unit with the correct Yanmar brand and that fixed it. As Danny said, the 1700 has a different unit from the 2000. Many dealers even the good ones will try to sell you an after- market one that is suposed to work on the 1700, 2000 and several others. DON'T BUY IT! Get the correct one made by Yanmar unless they have come out with the exact replacement after-market one since last summer.

I bought my sending unit from Hoye, and it worked perfect. I had my 1700 for about 3 years, and to stop it for getting hot, I had to replace the cap, and took a hose and washed the radiator, from the fan side high pressure many times. It took a while to get all the junk out of it. The inside was clean, but there was a lot stuck in the outside, after I got it all out, it never overheated again.

As I recall a 30/70 mix will protect to about 7 deg F. Since my tractor is outdoors all the time, I use 50/50 in the winter. Have had no problems to date. The tractor has a temp gauge and it seems to run at about the same temps with either mix, but I watch the gauge carefully with the 50/50 mix.

I think I will order a sending unit tomorrow.And see what that will do. if I get it fix I will let you all know.it may be better just to get a gage

I've had the same issues you've had as well as many others on my 1700. My light would come on in the summer. I eventually started running pure water to keep it cool. I put a set of gauges on her. She runs 220 to 230 with a 50/50 mix. I run 50/50 for the winter and then change out in the summer. I finally broke down and ordered a water pump from Aaron at Hoye. Won't need to change out the water now. Most report a 50 deg drop in temps.

I order a sending unit today from Hoye ( is it on the way yet LOL )when it gets here I will let you all know if that fixed it.
