Accidentally put OAT in tractor with ordinary antifreeze in it

[SAME123]

So, my tractor needed a bit of a coolant top up pre-harvest so i put some in..... Unfortunatley, I picked up the first can i found reading coolant/antifreeze and I put about 1.5 - 2 litres in. It was only recently I saw the can again and noticed it was OAT....my tratcor had a 50/50 water antifreeze mix in. Schoolboy error!

Do i have to drain it out or is it such a small amount it won't do any harm?

Cheers!

Probably safer to drain it, will do the system good and you could even flush it a couple of times, always suprising how dirty it can be.

Won't do any harm, but you won't get the OAT drain interval. It shouldn't affect the drain interval of the existing. You do know when the existing was drained last, right?

What is Oat ?

mixing the 2 can cause a reaction and it sets like jelly, for the sake of a bit of time and wasting some antifreeze drain it out and flush it through so you can start again.

Tractor is 10 years old and its been done 3 times so I guess a drain wouldn't go a miss but not a job I want to be doing at the moment!

Is it a faff draining? The book makes it sound like a right performance!

Just take filler cap and bottom rad hose off?

Thats what i was thinking but the book was saying to drain the rad, refill, run for an hour, drain again, fill again, run again, drain again and the fill for the final time! Just popping a hose does sound like a lot less faff!

Unless a really complicated tractor??
What is it?

Best advice here. Was only talking about this with our mechanic a few weeks ago. Told me a few horror stories of it going like jelly & causing big problems.

as said take bottom rad hose off if there is no drain bung, ideally find the drain bung on the engine block, drain both, refill with water only run for couple minutes with the cab heater on. Drain again both rad and block. Refill with correct antifreeze.

Drain it in the morning, fill with water and run it that day, repeat the next day, on third day fill it up with antifreeze mix or coolant if time is against you or just do a few quicke flushes

Drain n flush

Organic Acid Technology. I didn’t realise there were so many different types of antifreeze until I was told by our mechanic recently.

I usually just Connect a hose to a disconnected heater hose with all tapes open and filler cap off and flush away best in opposite way to coolant flow (mind no experience with a case)

What is in it now? and I don't mean what color. Antifreeze has to be one of the most confusing subjects that shouldn't be that bad. All the different colors, which are not standard and basically meaningless. The confusion over which ones might be ethylene vs propylene glycol. And what happens when you mix them.

The double flush is exactly for a situation like this that's gone bad, you'll know when you drain it if it's gone bad. GM dexcool is famous for gelling, I've only seen it once, and I suspect the antifreeze was original to the factory on a 15 year old car. Use rainwater for the flush, every gallon of hard water you heat up drops out more mineral, and the mineral is more a problem than the mixed additive package. If the first flush has sediment drop out, keep flushing until you get no more sediment. It will always discolor the water, that doesn't matter.
