In this video I replaced the turbo actuator / wastegate on my 15g turbo. The main reason I replaced it is because the rod was severely corroded and it could not be adjusted, to rusty. I was also hoping it was defective because I am under boosting.

I like when you're on the same project that I am. I haven't heard my turbo whistle in years so I'm trying to work on it. I ordered a new turbo control valve with new hoses. I read the old one can be frozen in a position that won't trigger an error code. Parts are coming in today and hopefully will find time this weekend to install it. Good luck with your turbo!!

[@RobertDIY]

When 20 things are wrong with a car, that is easy to do. LOLToday it is over boosting again so I need to keep digging for the solution to my problem, intermittent under and over boosting

[@csebastian71]

It feels nice and quick. Thinking about installing a boost gauge in order to see a value.

[@RobertDIY]

Sebastian Schwarz All turbo's should have a boost gauge. Not sure why the sell cars without them.

[@senordzabenda3271]

So this time i finaly signed in so that i can leave a comment and a thmb up. appreciate this specific and also other informative videos like this one. thank you Rob.

[@RobertDIY]

You are welcome

[@noahvaneyck598]

Yesyes, thank you sir. Going to fix a leak from the waste gate. This helped a lot

[@RobertDIY]

Excellent!

[@csebastian71]

Holy crap!! Going through boost/vacuum gauge overload!! Spent all evening reading about gauges. Mechanical vs electric arguments are fun to read. Have you installed any?

[@RobertDIY]

Sebastian Schwarz Not yet. I hope to withing the next 30 days. Most people use a pod or install them in a vent. T off the cluster boost gauge on the 850 which is run off the vacuum tree on the manifold. Tap power from the light switch.

[@raulfrancisco7915]

Robert yOu Are The MAN!!

[@cbrooen]

What dimension are the vaccum lines Robert? Are they 4mm inside and 9mm outside? Thank you for your amazing tips and videos

[@RobertDIY]

I think the ID is 4 mm

[@bobmartin3]

I like your video and the repair you made. Is there some reason other than cost you are not using new parts instead of gambling with ones out of a wrecking yard? I'm asking because this seems like such an important part.

[@RobertDIY]

Just cost. I've been out of work for about 9 years caring for a relative. OEM parts are very expensive to me and most after market parts are not as good as used OEM.

[@P80P2T]

Thank you Sir!

[@RobertDIY]

You are welcome

[@csebastian71]

Which kind are you leaning toward, mechanical or electric? I'd like to get a mechanical gauge but I like to have a peak recall and alarm function. Those functions seem to only be on electric gauges. The search continues.

[@RobertDIY]

Sebastian Schwarz I'm likely going to get a mechanical gauge to start. Bells and whistles cost money. LOL

[@AYoutubrrr]

the wastegate arm needs shortened a bit. It is not even boosting halfway.

[@RobertDIY]

What if there is another problem?

[@csebastian71]

My baby is a 1998 S70 T5. I am going to double check the pressure hopefully tomorrow. With the bad weather here in Chicago, am I just better off getting a new one or do they last. I have 153,000 miles on her.

[@RobertDIY]

Sebastian Schwarz They can last a long time, especially if you don't drive hard all the time. My car has 258,000.

[@csebastian71]

I couldn't believe how smooth it went to remove the heat shield and loosen the nut on the rod to test the wastegate after reading many horror stories. However, I think now it was too good to be true because after all that I believe I may have destroyed some diaphragm in the wastegate. When I tried to loosen the nut, I spun the rod. I realized that too late and then clamped it down to finally loosen it. I just read that if that rod spins you have broken the diaphragm inside. Is that correct? Did I just screw my self?

[@RobertDIY]

Sebastian Schwarz That is possible. I think the diaphragm is fixed / attached to the rod. If you need another one let me know. I probably can get you one cheap.

[@isilvacmx]

Great info...thank's

[@RobertDIY]

Thank you for watching.

[@J3Kmusicincs]

Hey Robert, I have a 04 v70 2.5t. I have a three code I’m trying to figure out. P0299, p0337, and p0017. Iv changed(new) both cam sensors and housing even checked the voltages(good). I’ve changed(new) camshaft sensor and mount also have good voltage at connection. Replaced pcv system and am going to replaced the waste gate to hopefully fix the under boost…..where can I find specs for the waste gate psi to make it or is it just the 4 psi you had done with yours? And can you help me with any other ideas for the cam and crank codes? I hope to hear from you. Thank you for the great videos

[@RobertDIY]

I'm sure the waste gate setting is different. Not sure what it's suppose to be. What's it set at now?

[@chaseblum3311]

Hi robert, what say you on the kinugawa adjustable wastegates? Volvo 850 turbo

[@RobertDIY]

They work. 👍🏾

[@rogwadd]

Much help, Robert. Thanks. I don't see a link for the "pro" 's method for removing the air intake. I'm going to be down there replacing vacuum lines soon. I've also got a question on your P0243, P0171 video.

[@RobertDIY]

rogwadd Not sure what you are asking.

[@rogwadd]

Robert DIY At 2:13 you reference a link. I could use a pro's guidance on getting that air intake off w/o busting it up. I also see you're on matthew's site. Thank you, sir.

[@RobertDIY]

It is almost impossible to damage the intake tubing. I guess I can do a video on removing and inspecting them.

[@parkerallen2765]

Watup Robert , I’m trying to install a new engine in s70, any idea how I need to set my waste gate or where I can find some info ?

[@silverP911]

Hello Robert - trying to adjust - turbo position looks exactly like my own - may have the same issue you have but in the meantime I'll try first - but dumb question for you: what direction do you turn the nut to LOOSEN it so I can lengthen the wastegate arm... ? also if I can loosen it what direction do I turn the end of the wastegate to make it a bit longer? thx

[@RobertDIY]

I don't even know what kind of car you have.

[@silverP911]

@@RobertDIY my bad Robert I should have mentioned that... it's a 98 C70 T5 automatic coupe

[@deborahl9911]

Robert , thanks for the wonderful informative videos!!:):)One question... I have a Cruze 1.4 turbo ( 79,000 kilometers) Is there any product to extend turbo life ie:preventativemaintainance?...also just had water pump & thermostat replaced ...what about water pump lubricant ??Thanks❓❓

[@RobertDIY]

Coolant lubricates the water pump.

[@jozzerful2]

Hey Robert my name is Jason by the way I went and subscribed to your friends stats channel so that he could get paid but here's the question how do you know if it's your turbo control solenoid or your wastegate is it not easier and cheaper to start with the solenoid if you are getting some overboost hope to hear from you

[@RobertDIY]

I'd start with the hose to the waste gate actuator. Then the solenoid.

[@csebastian71]

Do you think that if I was still able to apply pressure and see the rod move in and out, that it wasn't damaged? Or would I still see it move with the applied pressure being damaged inside? Any ideas to confirm if it is damaged or not?

[@RobertDIY]

Sebastian Schwarz Drive the car and see how it works? Don't slam on the gas, if it over boost it may damage the motor. What kind of car do you have?

[@csebastian71]

How much would you be able to find one for? I am sure you'll find them less rusted then the one's up here. Thanks.

[@RobertDIY]

Sebastian Schwarz I can't remember what they charged me for it but my guess is about $15.

[@atthehops]

Robert, I did not hear you mention that the engine warning light would come on or that there will be an error code indicating that it is a wastegate issue.

[@RobertDIY]

+Theodore A Hoppe I have not heard of to many people saying that they had a warning.

[@atthehops]

You know something,, I cannot find that there is a code for it either, but the other day my check engine light came on (I have a 1997 Volvo 850). I thought it was for the fuel evaporator since that has caused the check engine light to come on in the past if I top off the fuel tank too much. I decided to have it checked out and the mechanic that read the code told me it was a turbo wastegate code.

[@RobertDIY]

+Theodore A Hoppe good. Most people drive around with the CEL on or burnt out all the time. 🤔

[@srbinsrpski]

HI! Robert, I have some problems with my 850 T5, problem is underboosting, I think that problem is in turbocharger, because iI tried to drive car without vacum line on wastegate and it was like before. What could be problem bad waste gate or bypas valve, and turbo is in good condition.

[@RobertDIY]

Error codes?

[@osiris122cf]

What would happen if u put a used turbo in a car without setting the waste gate would the car die when it got to normal temp and bring up air fuel mixture code?

[@RobertDIY]

Probably nothing.

[@rlb19691]

Robert, my 1996 850 Turbo has a P0245 Wastegate Solenoid A Low code. Any Ideas?

[@RobertDIY]

kzbin.info/www/bejne/naWcqGCQiN2mb6s

[@mcdonald2037]

In my case I have a 05 auto Saab 9-3 2.0T my boost needle goes up and goes down normal I get what I put in needle doesn't shake or acts up and I don't let it get to the red . My question is on a stock 05 Saab 9-3 everything stock do we need to hear the wastegate make a sound when it release pressure like a blowoff valve pshhhh because I can hear my turbo sound like a turbine pick up quick but I don't hear any pshhhh sound when it releases presure is it normal not to hear the sound of a blow of valve. The car drives normal I just once hear the pweee sound of the blow of valve since the I hear the turbo built power but I can hear no blow off valve sound

[@RobertDIY]

turbo should be near silent. It does not have a blow off, just a bypass.

[@csebastian71]

I retested it this morning and it still moves back and forth as I increase the pressure.

[@RobertDIY]

Sebastian Schwarz Ok, have you driven the car?

[@homero5814]

Hi robert im from argentina!!! Can I increase presion on my 850 t5 stock turbo? Can i regulate the wastegate?

[@RobertDIY]

If you want to blow the engine. Best to do a manual boost controller or have the ECT tuned.

[@joesidneytetman]

Hey robert my check engine light on my 1996 850 turbo is on. The code is PO245 turbo/super wastegate solenoid A low. where is the solenoid? thank's

[@RobertDIY]

kzbin.info/www/bejne/naWcqGCQiN2mb6s

[@RobertDIY]

The last time someone was having issues with that code the MAF was bad.

[@joesidneytetman]

@@RobertDIY Thank's Robert I'll have it checked out.

[@zx8401ztv]

So did you have to wind the end out a couple of turns?

[@RobertDIY]

No, it seems to be adjusted in a good position. As you seen in the test drive, it was not boosting enough. However, today it is over boosting again so I need to keep digging for the solution to my problem, intermittent under and over boosting.

[@zx8401ztv]

Robert DIY Is the turbo itself going silly, can you move the lever without stickyness or does it move itself with nothing connected, like some kind of internal suction? Sorry i know nothing about the subject, sorry. What about locking the boost lever and see if it stays the same, just in case the turbo is playing up? Other than that, where is the suction coming from to drive the fresh actuator you fitted, is it the same source as the dashboard boost meter, can it get too much?

[@RobertDIY]

The car is fitted with a BCS (Boost Control Solenoid). The computer is suppose to read the metered air from it and the MAF and control the pressure on the waste gate actuator by the BCS. When to much pressure is building in the turbo, the bypass valve is suppose to dump the excessive air back into the intake manifold. The other day I actually unhooked the waste gate arm from the turbo and I had zero boost and no turbo power. So, my educated guess is that the old BCS is either getting stuck intermittently or it is simply not functioning properly. A lot of people remove the electronic BCS and install a manual boost controller so they can control the boost peak/max points.

[@zx8401ztv]

Robert DIY Ooow more complex than i thought, well the wastegate actuator is a fresh one so thats out of the loop, the turbo does shut down if the lever is set, so yes it does sound like you have nailed the problem to the bcs. So its back to the car scrap yard for a bcs.. Hope you do fix it, it would drive me potty lol.

[@RobertDIY]

Well, I tried a used BCS and it has the same issue. I'm going to order a new one very soon. Along with a real boost gauge that will show me the exact boost pressure.

[@lohnesj95]

Im assuming you are in economy mode. Seems low boost levels for sport mode.

[@RobertDIY]

Nope, sport mode always.

[@RobertDIY]

It started over boosting again Thursday.

[@lohnesj95]

Seems low. Mine goes way farther over. Your boost stopped climbing after a second or two. Might get a video of mine

[@RobertDIY]

It is over boosting again, I'll link a video in a few hours.

Tell us more ☺😏lol 🚗💗Robert.👍🔧

[@RobertDIY]

LoL

[@csebastian71]

I'll give you $20 if you find a nice one without any rust.

[@RobertDIY]

Sebastian Schwarz Well, if I have to go to the junk yard, pull it out, package it up, ship it to you, it will cost me way more than $20. So, if I go get you a used one it would cost you about $50. Check around and see if you can get a new one for close to that. Also, I can NOT guarantee that I can find a rust free used waste gate. That is part of the exhaust and it will likely have some minor rust but it would be serviceable.
