Replacing radiator

[BurningBushFarm]

Hubby pulled old radiator off our YM2000D. Got the new hoses, fanbelt and radiator. Discovered the chinese made replacement radiator (Hoye) does not have the clips for the screen.

Any ideas? Hubby is going to cobble up a solution, but if someone has already done this, that would be helpful.

Thanks.

Any way to remove the clips from the old radiator and put them on the new?

He is going to try and attach the clips (from the old screen, for the old screen) differently than they are mounted on the old radiator. I hear some thumping downstairs so maybe he is working on it now (I need my tractor!).

I thought of calling Aaron, but not much he can do about it.

Drill holes in the metal side brackets, and then zip tie the screen in. Will mean that you have to cut zip ties in the field to remove it, or you can brsh it with your hand then tap out at the end of the day?

I could figure something i just am not thinking right now. Id need to go look at mine as well.

I had the same problem when I changed the radiator on my 1500D. I just hold it on with a bungee cord connected diagonally across it.

Not sure there are "side metal brackets" which was part of the problem. In the original they are simply attached (welded? riveted??) to the side of the radiator.

There is a lip on the sides and the bottom, but they sit right on the radiator grill (<--- right word?) at the bottom and he didn't want to go trying to bend it out. Also the top of the radiator sticks out which would eliminate (or make difficlut) sliding the screen down the front.

Bungee cords are terrific ... but as I thought -- he was downstairs working on it. Made some new clips (bigger) while attaching them somehow between the fan housing and the radiator.

Turns out the screen is a leettle bit smaller (vertically) than the front surface of the radiator, but not a big deal. Should go on tomorrow. I'll see if I can get a picture before it's done, just so you can see it.

I have a replacement radiator as well, i did have the side brackets that hold the screen. My screen is wertically a bit smaller, but it keeps 95% of the area "pre screened" . The lip your talking about is actually the tanks of the radiator. My new rad clips are different than the original and not as good but acceptable. I got mine from my dealer but imsure its a china made, not like it was a yanmar one. Mine was exchanged under warrenty.

Another question. (This goes under the dumb mechanic category [or dementia]). Hubby has misplaced our manual (was for the 240, I think) since walking around with it in his hands last week. :duh:

Radiator in now, and he doesn't remember the cooling system capacity. (Also what is the best ratio 40 antifreeze / 60 H20?) Can someone post the info? YM2000D. (Has the Redline stuff also.)

I think we have a good excuse for the above, actually, as we had a major plumbing leak 2 weeks ago and have had the restoration people out with blowers, heaters, dehumidifiers, emptying basement out into 2 pods, and cutting away sheetrock, insulation ... the whole 9 yards. So we've been distracted.

I need my tractor working so I can go out and mow and forget doing inventory for a while.

Thanks.

Heh. I told hubby about that and he said "That was my first idea, but I figured you wouldn't go for it." (I have been giving him a little bit of a hard time for his make-do solutions )

on the Ym2000 its just like an auto, mix it for your climate. 50/50 antifreeze /water unless your in alaska then you may want to go a 75 antifreeze /25 water. The only ones that it really matters is the smaller tractors that use thermosiphon without water pumps. I think they have a max of 40% antifreeze or else the colling system wont work right. But with a water pump you can ron 100% antifreeze if you want and it wont matter.

Thanks Clemson -- 2000D have water pumps.

Some of the other posts on overheating from last year say 30/70, 40/60. So we got the idea it is not critical. Up here (Brevard, NC area) cold not such a big beal, and it is usually in the garage in the winter anyway.

Still need a coolant capacity #

Random rabbit trail I found a Yanmar (company) marine diesel letter recommending mixing the antifreeze with distilled water. Thought that was interesting in light of some previous comments on other threads.

The ym240 holds 4.4qts. Thinking the 2000 is about the same.

 

[clemsonfor]

Yea you want to always use distilled water as there is no minerals or such in the water to create deposits. So i do it, no. Should i yes.

And yea its somewhere around a gallon but thats not important, just fill it up to the top??? I always mix my antifreeze 50/50 for cars and tuck and such and just fill till full.
Oh and i know the 2000 has a water pump thats why i said that, i have one!

Interestingly, pure ethylene glycol (the basis for most antifreezes) will freeze at about +10 F. Optimum freeze protection is 70 % glycol, 30% water which freezes at -60 F. So it may seem odd, but pure antifreeze provdes minimal freeze protection.

good to know, although i think i have seen different on the back of an antifreeze bottle.

quick search found this. The disclaimer kind of points contrary to wht your link says? It says it does not improve significantly but does not say it goes drastically down either like what you say?

I don't claim Wikipedia as an absolute authority. As you might know, Wiki articles can be posted by anyone and essentially modified by anyone. This opens any "facts" on Wikipedia to biases, fraud, or outright falsehood. I think one point to remember is that for antifreeze to work properly, you need to add water. It looks like 70% antifreeze, 30% water provides max. protection.
