GC17xx, coolant change

[ammoaddict]

Addict, My MF manual says to use Massey Ferguson coolant but no specs are given. Also, the manual says change at 1000 hours. I change it a bit more often that that. I think that a quality 50/50 anti freeze is sufficient. Also, I change engine oil every year as well as the oil filter. I use Mobil Delvac 1300 15w-40 engine oil and a Wix oil filter.

The transmission is speced to use Permatran tractor fluid. I have changed it twice in two years.

Thanks for the info. I changed my oil at 500. I haven't changed it since, it still looks good. I have added some permatran but never changed it. How much fluid does it take for a change?

I posted this link a month ago. Thought it good enough to post again with the discussion of water only, and diesel rated coolants. All depends on how long you want to keep the engine.

Where are the block drains can maybe you take a pic? I think I know where it's at I just want to be sure.

I think it was the square bolt to the right of the oil filter.

Yup that's it, thank you!

I don't understand, so that has to be drained as well, not just the radiator and overflow tank?

Many engines will hold as much or more coolant then the radiator does.

Removing that plug drains the coolant out of the block around the sleeves so you're getting a more thorough draining of the complete system

Gotcha, thx.

Gotcha, thx.

NP good luck!

My GC1725 manual specifies 40 to 60 percent ethylene or propylene glycol and to be changed every two years or 1000 hours

Guys, reading the manual, mine says the drain tube drains both radiator and block, so I'm curious why people here are advocating draining the block separately. Is it to squeeze every last bit of coolant that be stuck in the recesses of the block? If that's the case, ain't it kinda overkill?

I did mine yesterday, I didn't unscrew the plug on the block. I just drained via the tube, then flushed with distilled water, ran that a bit, drained again, and filled it all up with new coolant. Obviously did the overflow reservoir as well.

If you are changing it on a regular basis, any residual amount is diluted. So, it's no big deal.

Changing coolant every two years, for most people is overkill.

Sometimes the "feel good" factor is worth it to people.

Distilled water would be the best

Why? Distilled or deionized water is unnecessary in your radiator. Once you ad coolant, your adding various solubles to the cooling system in order to keep the metals in your engine happy. Flush with a garden hose and ad the appropriate coolant mixture. If you have extremely hard water, you might want to use store bought water but only in extreme cases.
