Can I Test the Turbo At Home?

[zakmuh]

Hi,

I've got a 2003 Sorento 4x4 2.5 CRDi. I just want to know if I could check the turbo wastegate actuator is working by revving the engine high, parked on the drive way.

Would this make the wastegate lever move or do I have to drive the car on the road to test this?

I'm just cleaning up the engine, so as I'm at it, I want to check it. Any help on this is highly appreciated.

Cheers

Thanks for your reply. I think it's seized.

When you rev high, it builds pressure from the exhaust and that would be enough for the actuator to kick in, I thought?

Okay.

I have to check with a pressure meter then.

Interesting..............

You want to test a part, kudos for having a go.
Do you know where the actuator is?



The part with the hose missing is indeed your actuator.

Thanks but the wastegate actuator is on the turbo unit, right next to the exhaust manifold and it has a vacuum hose connected to it - the one on top of the inlet manifold, shown in my other thread pic is NOT the actuator.

Like he said, I can test the actuator with cycle pump. when pressure is pumped (not pumping), the lever should stay for 30 seconds or so

There's a hose connected to the wastegate (which I've called it 'vacuum hose') but I don't know whether the actuator is activated my pressure or vacuum.

I'm not a mechanic, just a DIYer and that's why I'm here seeking advice on this issue

Noted, I'll let it be as it is

The EGR valve and the intake manifold is all clogged up, I suspect the wastegate must also have got carbon built up. So I wanted to check if that lever rod is moving or stuck.
