Changing enginee coolant

[Beneteau381]

Try using DoT5 fluid Richard. It's silicone based and doesnt absorb water. The advice is that it never needs replacing though BMW initially recommended every 2 years on my bike.

Having said that I have only once ever had to replace a slave cylinder even on the old glycol based fluids that did absorb water.

I'm not usually that cynical but as a retired businessman I know what I would do if selling these sorts of fluids. I would recommend changing them as frequently as I thought I could get away with. After all, I would likely be supplying the car maker / bike builder at not much more than cost ( that was my experience of them ) so all my return would have to be be made from the after market.

Same sort of thing with spark plugs.

And how did this come up? Are the techies trying to do the biz whereby anything you are interested in as per your cookies, then up pops a zombie thread? Is our resident community mod going to address the issue raised or is he still going to do sarcastic!
Is this what is causing the forums to turn in to treacle?

I don't understand why you have revived this zombie thread?

It was there on the front page. I noticed a while back that these zombie threads were appearing and wondered why! I asked the question as to why and one of the community mods did his sarcastic reply! Since then Ive tried to find out why they are appearing, We were discussing coolant and fouling in the cooling system on a 2030 and lo and behold a zombie coolant thread appeared on my page. I suspect that the techies have set the system to drop cookies on our machines and they then serve what they think are relative interest threads to each different one of us. I suspect that each persons front page is different. A bit like the MP who took the piss out of his opposition number about his sex browsing habit, not realising that it was his browsing habits that were serving up data that the computer thought was relevant. This forum has been like watching paint dry today, again I suspect due to what I have just described. Dont forget, as I understand it, the new owners mode of operendii is to buy failing paper assets, digitise them then sweat the digitised assets!

Just like your car engine the interval between changes depends on the type of antifreeze....

Yes and no.

Yanmar, I believe, specifies changing every year, and the reason is chloride contamination. Even the smallest leak (<1%) in the heat exchanger will drive the chloride level off spec. Yanmar is fine with 5 years for the very same engine in land-based service.

Which brings up an interesting point. Maybe you want to test the coolant for chloride, to find out if you have a leak. Maybe you can find a neat multi-test strip.

I see. That's very strange as the only threads that I ever see on my front and subsequent pages are threads listed in the order of the last posting on the thread. I never see an old thread unless someone has posted a new addition to it. Admitted a lot of old threads do seem to get revived but there is always a reviving post to blame.
