VP D2-40 Coolant Change

[CJ13]

I have a 2006 D2-40 & am ashamed to say I've never changed the coolant.
Could someone who's done this give me idiot proof instructions?

Thanks,
John

You will find the instructions in your owners manual

If you have mislaid your copy you can down load one from VP's website http://www.volvopenta.com/volvopent...lication_search/Pages/publication_search.aspx

Whether you use the conventional (Volvo Green) type or the long life OAT (Volvo Yellow) type I think may depend upon the which version your's is and what is in there at present. The two types should not be mixed and there are special flushing procedures if changing from one type to the other

Essentially no more of a job than changing the antifreeze in your car . Drain out the old and refill with new although VP do suggest cleaning the HE.

I'd agree with the suggestion for cleaning the HE. Rydlyme makes a good job of this without any mechanical dismantling.

Its the fresh water side of the HE that VP suggest is cleaned simply by flushing.

The Rydlyme treatment would be more suitable for the seawater side

I was thinking of the seawater side. Did it on my previous boat at about 8 years old and was surprised at the amount of debris it flushed out.

Easy enough job - except I struggled, with the poor diagrams in the manual, to find the drain bolt on the block.

D2-40 uses Volvo yellow oat coolant. There are 2 plastic drain cocks on the block.

Are you certain ? Does it not depend on age ? And they do not mix well if get it wrong.
Our similar D2-55 had the green conventional and so decided not to go through the rigmarole and risk to change

I have the d2-40F from 2014. Definitely has the yellow OAT coolant. It is correct you must not mix them but a good flush with water and you can change over if needed. My manual says change coolant every 4 years and clean heat exchanger every 2. Hope this helps

The yellow VCS or OAT type is specified in the manuals for the D2-40F but not for earlier versions . It may be suitable provided the green stuff is flushed out but I cannot access the full list of applications at present..

I think you will find that there is only one drain cock on the engine block and one other on the HE.

In cases where a change must be made from Volvo Penta Coolant (green) or equivalent to VCS (yellow),
the cooling system must be cleaned using oxalic acid; refer to Service bulletin 26-0-29 for instructions.

Our existing coolant is green. Is any green coolant from a garage suitable or does it need to be a special formula?

The first thing to be aware of is that there is no standard for the colours. VP happen to use green for the conventional antifreeze and yellow for the long life or "organic acid technology" (OAT)

Other manufacturers use different colours. Blue is also common for the conventional type ( Halfords' conventional af is blue) Red, orange, yellow are all used for the OAT ( Halfords' OAT is red )

You do not have to use VP antifreeze. Any brand of conventional / inorganic acid / low silicate antifreeze sold for older cars will be suitable.

Read the label rather than choosing by colour!

Consider buying it ready diluted if your tap water supply is hard or high in dissolved solids, otherwise it is recommended that distilled water is used for dilution
