KAD32 More 'newbie' winterising Q's

[SgtColon]

OK So whilst facing my first ever winterising of my S23 I now understand what they meant when they said to work on the engine I would need to be part gynecologist / part contortionist. Its so difficult to find anything down there. Armed with the Volvo Penta instruction book I have drained coolant from the hose (not marked blue), but on the heat exchanger I can only locate one drain cock (not two per the diagram) . The diagram shows a separate circular shaped fitting with two further freshwater drain cocks but I can not see this fitting. Could it relate to one of the other Penta engines not mine?

On the seawater system draining instructions the book suggests removing the seawater hose from the shield. I am presuming this is out of sight on the port side of the engine. Does anybody actually follow this instruction or generally do other owners just drain the seawater from the hose (with the blue marking under the heat exchanger) and from the plug beneath the charge air cooler.

I should point out that the boat is out of the water on a trailer.

In the cabin the carpet prevents me from getting to the shower sump. Will this be a problem?

Finally .. and sorry if this sounds stupid but do I have a reverse gear? I know I can go backwards but under seawater system draining the book refers to ... Engine with reverse gear close the sea cock drain oil cooler by opening plug 2 (a feature I do not recognise down there)

Any advice appreciated (except getting somebody else to do it)

P.S I purchased a Volvo Penta workshop manual 'Engine body' I was hoping it would help me identify items to maintain eg the supercharger, etc but it mainly deals with the aspects of removing the entire engine and dismantling it so not anything that will help me. Can anybody identify the manual I should have purchased .. you know bit like a Haines car handbook.

Thanks
Graham

>> I have drained coolant from the hose (not marked blue)
Umm, why did you do that? The coolant is antifreeze.

>> I have drained coolant from the hose (not marked blue),

There is only one. Just loosen off the end piece. The thing marked "3" is a hose in front of it (diagram is from behind).

>>The diagram shows a separate circular shaped fitting with two further freshwater drain cocks
Circular fitting is your turbo. It's at the back left hand corner if you are standing in front of the engine.

But again, this is draining antifreeze.
You need to "flush" the saltwater circuit with antifreeze, not drain out the freshwater system.




In terms of the seawater hose, I normally disconnect this below the seawater pump, and connect another smaller hose to the pump leading to a bucket of antifreeze, then run the engine for a few secs until the antifreeze has been drawn through. Then tip some antifreeze down the hose you disconnected to protect the oil cooler.

If you have an outdrive, you do not have a reverse gear thingy.

And yes, it's all much easier if you watch someone that has done it before.

I would also drain the shower sump, water system, and have a couple of tube heaters and a dehumidifier on board.

Hi Graham

Just read your post.
First you do not have a reverse gear (box), you have an outdrive.
Do I assume you are leaving your outdrive on. the reason I ask is because if you are it is easier to put an antifreze mix through the engine without having to drain it down. When my boat (S28) comes out for it's 6 week layup I first place a pair of muffs on the outdrive connected to a hose pipe and flush the outdrive and engine to get rid of the salt, then when the outdrive is removed I have a short hose connected to the 's' shaped hose on the transom shield that is placed in a bin with an antifreeze mix in. With the engine running it sucks the mix through the engine and comes out the exhaust outlet into the suitably place bin. Once happy with the mix circulated through the engine, stop engine remove hose, then the impeller and check water filter is clean. Well it works for me.
The only hose I drain some off from is the one without the blue band, this is the antifreeze one. If it has not been done for a while you may have to 'rod' the rubber tube to get anything out. I normally wait until I get a good flow of anti freeze before stopping. Then fill the expansion tank up with fresh antifreeze mix, don't fill to full on a KAD32, just to min will do otherwise it will chuck it out the lid.
I hope this is of some help, any further questions please do not hesitate to ask.

Thanks guys …. Much clearer now … So boat on trailer in storage yard until beginning of April. No access to water hose pipe and had no plans to remove leg.
Had thought if freshwater coolant completely drained would eliminate any danger of freezing but the very clear green liquid that was drained would suggest it was antifreeze not anti corrosion agent so I will fill that back up with antifreeze for the winter lay up. That just leaves the seawater coolant so I will try your suggestion of replacing that with antifreeze if that is a better option to just draining it. Did look at the MBW winterising video but presumed that was for boats left on seawater. Can’t get to the shower sump so will tip some antifreeze mix down the plughole.

hi sgtcolon.... on my kad32 i drain the BLUE HOSE ONLY, and push it as low as poss into the bilge, remove the aftercooler drainplug AND remove either one of hoses that go into the top of the aftercooler lid, also remove the water intake filter and leave the lid off..i also pour antifreeze mix into the filter holder untill the coloued mix apears out of the OPEN BLUE HOSE INTO THE BILGE...it pushes any water out!!....... right or wrong, i,ve also poured antifreeze mix into the shower floor drain untill it gets pumped over the side.....hope that helps..

The shower sump should be under a small hatch under the edge of the mid cabin mattress.

Also remove the transom shower head

It is very important to drain the domestic fresh water. I just let the pump rum opening the taps in turn. If in the spring the saloon carpet gets wet this is because the mixer unit in the head which is plastic has frozen and split (happend twice to me)

hi elza_skip .... im lucky that i dont have a transom shower !!!...i have had the showerpump out before now but antifreeze saves a lot of grief !! as for the domestic side, pump on untill dry, all taps emptyed and left open, drain plug removed from hot water tank...
