Probably the most straight forward, informative, easy to follow along repair video I’ve ever seen

[@bofbolts]

Thank you!

[@TheSpeedula]

One of the best DIY videos I've seen. Most of the time these things look like they were recorded in the river styx.

[@bofbolts]

Hah, appreciate it!! 🤘🏼

Great DIY help! Thank you so much for making this video.

[@vsurg]

Couldn’t have done it without you. Since I have the Turbo, the inter cooler connecting pipes made the job harder. Thank you!

[@bofbolts]

Glad I could help!

[@mikeramberg4776]

Thank you so much for posting this! I just did the thermostat on my 2012 Cayenne Turbo and this video was very very helpful! Best things learned were how to pop the clip on the lower radiator hose to drain, how to use a strap to pull the old stat out, and also making sure I had the 30mm socket for the belt tensioner. Excellent video!!

[@bofbolts]

Glad it helped!

Great video (thanx for the torque specs). I have a 957 that I'll be replacing the starter for soon, and I have a very slow coolant leak (the reservoir level drops a tiny bit during the week, so I've been topping it until I get all the parts/tools that I ordered for the job). I suspect it's the thermostat socket (I will know when I remove the intake manifold and inspect the V).

Thank you for taking the time to do this and for keeping it short and to the point, well done sir! Do you have a link to the Cooling Vacuum refill kit? I see several on Amazon but none have the same cap you show that threads onto the overflow tank.

[@bofbolts]

@gregeast147 thanks for watching! There are many sellers on Amazon with the same product, just labelled under different brands. This is the kit I purchased, but any 28PC kit from any seller should be identical if the photo matches. I'm In Canada - if you are in the US you should be able to find the identical product by searching 28PC Coolant Refill Kit. www.amazon.ca/28PCS-Radiator-Pressure-Tester-Kit/dp/B09H5M4D96/ref=sr_1_3_sspa?crid=2OPVV4USFLB5M&keywords=28pcs+coolant+refill&qid=1672933471&s=automotive&sprefix=28pcs+coolant+refil%2Cautomotive%2C88&sr=1-3-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExTlkyNzBQMEtNUjRZJmVuY3J5cHRlZElkPUEwMzM1NDc2MUNCMDROMDBHV081SiZlbmNyeXB0ZWRBZElkPUExMDI3NzI3MkdESFpOMVNYTzJYUCZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=

Thanks! Glad I could help. Yes I will be, are you looking for any other Cayenne specific content? Consider subscribing :)

[@eliaszafrani]

Definitely one of the most explained and detailed videos about 958 cayenne. And I have seen a lot. Let me ask you, to fill up the coolant it is necessary to do the vacuum thing? If it is, can you give me what is needed to buy? Regards

[@bofbolts]

Thanks, I appreciate the comment! Like and subscribe, it’ll help me out! It’s definitely not necessary, but you will have to continuously “burp” the system and top up, drive, top up, and perhaps get stuck with an airlock. It’s no fun. It’s always better to use the vacuum method so you can ensure it’s full and you have nothing to worry about. It’s also really good method to ensure you have no leaks at the same time. You can buy any coolant refill set from Amazon, they’re all basically the same labeled under different sellers. Just search 28pc coolant refill kit This is what I used: www.amazon.ca/28PCS-Radiator-Pressure-Tester-Kit/dp/B09H5M4D96/ref=sr_1_3_sspa?crid=2OPVV4USFLB5M&keywords=28pcs+coolant+refill&qid=1672933471&s=automotive&sprefix=28pcs+coolant+refil%2Cautomotive%2C88&sr=1-3-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExTlkyNzBQMEtNUjRZJmVuY3J5cHRlZElkPUEwMzM1NDc2MUNCMDROMDBHV081SiZlbmNyeXB0ZWRBZElkPUExMDI3NzI3MkdESFpOMVNYTzJYUCZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU%3D

[@eliaszafrani]

Thanks so much for answering. Certainly I will subscribe since I have the same car but turbo. And I have a mechanic shop but for Lexus and Infiniti only. And as you know Porches are different cars and difficult to understand, plus there is not much information about them for repairs.

[@bofbolts]

Porsches are surprisingly quite easy to work on. Especially the Cayenne. It’s a glorified VW after all :)

[@eliaszafrani]

@BucketofBolts Well, let me tell you my experience. I dismounted everything on the dashboard and the air conditioning unit to change the evaporator on many Lexus. It's a lot of work but practically easy to do. I'm just doing wring now the same for my cayenne turbo and definitely is a totally different thing. Very, very much more complicated, more plugs and modules. But it is definitely a very well assembled car compared to Lexus. Certainly, they are glorified VW and easy to work on IF you have worked on VW and/or German car.

[@eliaszafrani]

@BucketofBolts Let me give you a clear example. If you have to change a seat belt or even a brake actuator with the ABS on a Lexus or Infiniti, just replace them, and that's it. On Porsche, you have to read and re-write everything on every module. And that is a hassle. Regards

[@ahmednajim3752]

What does the service Bleed valve do

[@chrismtse]

Great video! About to do my thermostat in a couple days, but I wanted to ask, FCP Euro Thermostat kit only includes 3.78 L Coolant. Will that be enough?

[@bofbolts]

I don’t think so - I used approx 6-7L on this job. That included top-off after a day of driving. Goodluck!

[@totoole6262]

@bofbolts Incredible video. I have a 958.2 turbo. Just had the water pump and thermostat replaced and now coolant is leaking everywhere under the car. My service garage is now saying coolant leak is coming from under the intake manifold. Does that seem likely that they wouldn't have noticed when replacing the thermostat and water pump? I'm now highly skeptical. I really appreciate any insight you can provide. Thanks, and again, awesome video!

[@bofbolts]

Ah that really sucks! It's actually quite common for the pipes under the intake to fail on pre-2013 and some 2014 958's. That being said, definitely odd timing that it failed after you changed the water pump / thermostat. I would say just confirm the leak isn't coming from the thermostat/water pump job they just did. If it's coming from under the intake, its definitely not UNCOMMON for the

[@totoole6262]

Thank you so much for your reply. Mine is a 2015 with 97k miles. Just really surprised with the timing. Just paid 2400 back on 10/31/23 and they just quoted me 2600 to replace intake manifold gasket and replace starter mostly.

[@bofbolts]

That's crazy strange timing, but you ran roughly 3 months leak free - so maybe it did indeed fail. Hard to really say unless you take it apart and look for yourself. It's also hard for the shop to tell unless they also take it apart.... I wonder if they did? Ah, the joys of a Porsche :)@@totoole6262

[@totoole6262]

I sincerely appreciate you taking the time out of your day to reply and provide your insight. The shop has most of it broken down and I’m going forward with the repairs. My wife says I should just drive a lifeless, extremely low maintenance Prius like she does 😂 NEVER!

[@lalfaro77]

Excellent video, does it also apply to a V6 Cayenne GTS 2016? Also where did you anchor the strap pulley?!? 😂😂 that sucker came out nicely

[@bofbolts]

The V6 is a bit different in that the thermostat and water pump are not in the same location. Water pump is very similar procedure and very easily accessible. Remove the belt, 3 Torx and the pump slides out. The thermostat is on the side of the motor right under the intake manifold (also easily accessible). Lol, no anchor for the strap - just used good muscle and a firm pull 😁

[@liquidflorian]

Thanks for this video! I have a 2011 Turbo and aside from the turbo pipe work it looks exactly the same. Question, is their a good way to add coolant with out the vacuum device?

[@bofbolts]

You can definitely add coolant to the reservoir and burp the system by manually squeezing the large coolant pipes and look for air bubbles at the reservoir, let the car run at idle and get to operating temp, keep on topping up the reservoir - but it’s a slow process and sometimes can be a pain to get it to burp out the air. I highly recommend the fill tool, which also allows you to check for leaks.

[@bofbolts]

@@liquidflorianI would attempt to burp it without the bleeder open, but if still no luck then you can try the bleeder. I’m surprised the tool didn’t work, did you pull a strong enough vacuum? And did you replace your thermostat?

[@liquidflorian]

@@bofbolts The burping worked, I did both with the valve open and closed. I'm not sure what happened, I mixed the 5L of coolant 1:1 with water according to the instructions, but ended up with 4L left over. The vacuum exchanger worked but It didn't take the whole mix. I have a lot left over now. lol I had done Thermostat and Water Pump. The Pump was still good, but I figured while I was there I should change it out anyway. My thermostat had been leaking bad.

[@leooneill1693]

Great video. Is it the same process on a 957 4.8 GTS model. Thanks

[@bofbolts]

Specs may not be the exact same, but yes for the most part. This video should be very helpful for the 957 .

[@leooneill1693]

I'm thinking of buying a 1 owner, low mileage 2008 GTS, and am concerned about possible maintenance problems in the future. Can do most jobs myself, but this will be my daily driver.

[@pete9024]

Thank you for posting love the video. I have 2012 Porsche cayenne. I have a small hole by the thermostat housing leaking coolant. I don’t know what to make of it. I have a video. Can you help?

[@bofbolts]

Sure, if you post it I’ll take a look and try to help!

[@pete9024]

I sent the video to the gmail account you have on your page.

[@pete9024]

@@bofbolts I posted it on my page. Thank you

[@bofbolts]

I see your video - it’s really hard to tell what I’m looking at. Can you try another video but show me the front of the motor first and then zoom into the leak? From what I can tell, this is the metal coolant pipe that runs under the intake manifold. Again, really hard to tell what I’m looking at though from the video.

[@pete9024]

@@bofbolts Ok when I get home I will send it. And yes the coolant leak is right underneath that cooling pipe which is also connected to the thermostat housing. In the video coolant bubbling out of the hole

Amigo tenho uma cayenne s 2009 , andando na estrada em dias frios a temperatura do líquido refrigerante fica a 40 graus e a do oleo 80 graus , esta normal ? Ou termostatica esta travada aberta? Obrigada pela atenção.

a la temperatura de funcionamiento, el refrigerante debe estar alrededor de 90 grados y el aceite debe estar alrededor de 90-100 grados.
