135 coolant

[evdama]

Planning a change once the quagmire can be walked upon.
I recently changed the water pump on my van and the refilling process was fairly involved requiring a gravity filling device and two almost inaccessible air bleed points.
Please tell me I'm not going to have fun and games with the tractor as well?
Is it just a drain and refill job?
Also can I use "modern" pink fluid?

Yep; just fill it in the radiator cap; give it a run for a couple of seconds and then top up. Anything will do. I use whatever we have for the big tractors; usually CoolGard

Bargain.
Thanks.
Is there more than one drain and any idea roughly what the capacity is?

There probably is an awkward one under the rad; I just drop the bottom hose. Can’t remember the capacity. Not a lot. Watering can full? Ish?

Block drain tap behind the fuel filter.

In this case, I'd flush it with distilled water or rainwater by draining as much old coolant as possible, filling it and working it an hour or so, then draining hot. If there's a lot of sediment that comes out, refill and run another half hour, then drain and repeat until there's no more sediment. The color of the water never bothers me, just the sediment. Then fill half the capacity with concentrate and the remainder with distilled water or rainwater. Looks like 9.9L or 10.5quarts, so 1 gallon of concentrate should work.

Don't use the modern pink stuff,
Old rubber type seals just don't like it, and it eats them away in older engines.
Just use the cheap blue antifreeze, it will do the job at right strength
