bleeding the turbo on a volvo penta 2003T

[mariog]

Can somebody indicate to me from where I should bleed the water in the turbo on a Volvo Penta 2003T?

A turocharger should have 3 things in it. Fresh air ( varying volumes ), exhaust gas ( hot and varying volumes ) and oil, significant quantities.

Water .......... Non!

Water injection should be downstream of the turbocharger system!

What makes you ask this question!!!!

Somewhere on this forum I had read that the turbo should be bled from air after draining the water system

Some confusion here. No water in the turbo-charger. Maybe you are thinking of the inter-cooler?

Yes, you must bleed the air from the 2003T turbocharger to ensure that it is correctly cooled in operation. The bleed screw is towards the top of the turbo, facing towards the front of the engine. It's item 26 in this parts diagram...

THANKS SO MUCH! though I can't see the diagram you posted I think its the exploded view of the cooling system, induction and exhaust manifold. with the part nos. on the side.

You're welcome. It is the diagram from the online Volvo Penta shop. Here's a direct link http://i87.photobucket.com/albums/k126/pvbpics/turbo_zps5dcfaa8c.jpg

It's a very interesting thread. I had wondered about the safety of turbos in boats. In the dynamometers at Shell Research there was turbocharged BL engine running on a long term lubricant test. A party trick for visitors was to turn off the lights, upon which the turbocharger could be seen glowing red hot.

My 2003T's turbocharger certainly doesn't glow red-hot! As you can see from this pic, there's a bit of discolouration on the green paint, but the turbo is the original one so is 20+ years old.

Some marine engines do have water cooled turbos which are safer as it can make a big difference to the surface temp.

That was my point. I had not come across a water cooled one before.

Quite true but it shouldn't need bleeding.

Earlier in this thread you claimed "Some confusion here. No water in the turbo-charger." Now that it's been shown that some are water-cooled, you claim they shouldn't need bleeding. Of course it needs bleeding - it's at the highest point of the engine.
