Changing engine cooling

[luggsy]

Finally got round to changing the engine cooling ( after buying antifreeze nearly two years ago ) was very apprehensive doing it and not being able to get all the air out when filling back up . Well it was very easy but messy but not any more, the original bottom hose went under the engine and gearbox making it very difficult to drain the gearbox oil as I could not get anything under it to catch the oil , not any more as you can see from the picture, all I have to do now is connect a pump on the hose that comes off the ball valve , open the bleed valve on the skin tank , then open the the ball valve , turn the pump on  , pump it into 25 ltr drums, it works great as I flushed the skin tank out five times , takes less than ten minutes to empty and no mess , I have taken the handle of the valve now just left it on so you could see it , also my son took the old antifreeze to his mates garage for safe disposal

That’s a great system what type and size is your pump? I’ve spent most of last Friday draining into my bilges then pumping the out the bilges not something I want to do again.

Hi Dave pump is one of these https://www.ebay.co.uk/itm/38mm-Diesel-Fuel-Pump-DC-12V-Transfer-Pump-40-Watts-Oil-Fluid-Refuelling-TT-UK/383667859603?hash=item595462f093:g:3fcAAOSwKaVfLWg8

So you still drain the coolant into the bilges? I thought you had inline pump to Pump the coolant straight into a container but I still like the ball valve idea thanks for the info.

Dave i fit the pump on the end of the the hose that has the end cap on then pump it into 25 ltr drums , no coolant goes in the bilges

Sorry when I read the eBay blurb it said semi submersible so I assumed you put it in the bilges, that makes more sense And I still think it’s a great modification should be standard on all new boats.
