Cooling fluid- how to exchange in my Yanmar 215?

[vitara]

Can you tell me how can I change cooling fluid in my engine Yanmar 215?

I must old cooling fluid remove , but how to do this?

Not familiar with the f215 but common sense can get your through this. Remove the bottom radiator hose in order to completely drain the system. Might be a drain plug down low someplace. Might want to flush a little water through the system. Don't worry about the fluid in the over flow resevoir, it will be ok.

yep either pull the lower hose off like Winston said or look for a petcock or a bolt in the lower radiator or look for a smaller drain hose running out of the radiator to a fitting with a bolt head in it. My 30 year old YM2000 has a drain petcock thing right on the frame with a hose running from the radiator to it and from the block as well. simply removing that bolt and the whole system will drain into a bucket. I flush it with a hose till it runs clear then refill then turn on and fill it full again once air pockets are filled.

I am sure a newer one will have a drain on it as well

The F215 has a drain tap under the radiator on the Right Hand side connected to both the radiator and block. To drain simply unscrew the tap.
