Volvo Penta MD2020 - removing coolant drain plug

People say it is a total nightmare to screw out this small square plug.
It has taken me a lot of time to find out what tools I need for this plug type tue to the funny square design.
After a lot of searching I found a oil drain plug set at Biltema where this special size is included.
BATO 12880 CR-V XS10 - price 10 US Dollars
Biltema suction pump - price 20 US Dollars

Merci beaucoup ❤❤❤❤❤

Love your videos. Very helpful as a fellow MD2020 owner. Love your obsession with green paint. I don't have much left on my 1996 version.

[@twiper]

In my search for paint I have found out there is some primer for iron and some for aluminium, and also a zinc based primer for the brass parts. The Volvo green spray paint you can get for aound 32 US dollars so a light paint renovation is quite easy.

Hmmm! Once I halt the water leaks and the oil leak and the rust fest, i'll be ready for the green stuff.I also enjoy your accent, having spent some time Offshore Denmark, it is a positive reminder of some of the nice people I met. It's true what the say. "There's nothing like a Dane!"

Well done captain .. on to the next job

[@allenpew8544]

Remove the coolant drain plug while the filter is off . That way you can get your fingers on the plug . Also put some rubber sealant on the threads when you put it back in .

Hi Tino, Love your videos of you renovating this engine. One small issue - I think above the BATO number should be 12882 and not 12880?

[@mikewomersley7888]

Well done Tino, I have exactly the same boat and engine , probably the best explanation of servicing this engine and boat maintenance ever. Are you going to tackle the seal on the sail drive?

[@twiper]

Thanks :) - Mads from Sail Life has just changed his "seal" on the saildrive. Check it out here : kzbin.info/www/bejne/pqinYYdvqNCeiqc - I have not any plans to change my seal because I know it can last +30 years. But when I get the new 39-40 foot boat I'll change the seal due to my "Sailing around the World" project.

You can buy a small tap and an adaptor (from Volvo), then you can use a hose (and no tools) when emptying the coolant, so you avoid the cleaning mess

[@niclasasada8712]

Michael, can you be a bit more specific? Thanks/Nic

Why aren't you showing the paint process? I have also some paint job on the engine and don't know well how is the best way, I bought volvo green engine spray, after sanding the surface is it enough 2 layer?

[@salvadorrodenas3071]

What happens with a broken blade of the impeler? Where does it gets and if could it obstruct the circuit in some critical place?

[@twiper]

When a impeller blade is broken off it will be sucked into the system and then floating around infront of the heat exchanger. But I think a lot of broken impeller blades must be present to make a cooling problem. No blades in the system is of course most optimal.

Thanks ​@@twiper

[@heikodorn6064]

Hi Tino, do you remember the torque for fastening the drain plug? Thanks in advance and best regards

[@twiper]

There is no torque specks for the drain plug. I also asked someone from Volvo penta at a boatshow to verify. They said it must be good hand tight.
