Just found out you need to remove the intake manifold, throttle body, and fuel injection pipes to get to this hose.

 

Mine has this problem now. In the shop as we speak. Will be done tomorrow. Under warranty so im happy

 

For a Porsche repair of that magnitude, $550 sounds like a bargain. Ever hear what some dealers charge for an oil change?

 

In Canada this costs from Porsche Centre $3263.67 -2018 Macan S with 54000 kilometers.

 

I owned a BMW that has a similar design.


Bad engineer! Bad!! Bad!!! They should make the engineer's who designed this (mess) perform the repairs!

 

Cayennes have (had?) coolant pipes under the intake manifold too. Early plastic pipes leaked and were replaced by aluminum.

That said, the intake manifold is easy to remove - which is why the quote is so low.

Not major surgery and not bad engineering

 

this just happened to me last night.. will be replacing the line myself and uploading some pics..

 

1st Pic
1 - Remove both (L+R) non-return lines and valves, move aside the breather lines
2 - Remove Throttle Body Hose (Flat Head Screwdriver)
3 - Remove Sensor Plugs and Bolts and move aside
4 - Remove 8X Intake Plenum Bolts using a Torx Bit. Move aside the wiring harness, sensor and bolts. Carefully remove the Intake Plenum

 

Having problems with step 1. Can anyone tell me how to remove the L+R lines?

 

2nd Picture

1 - With the intake plenum removed, proceed to remove the Secondary Air Pump. 3X Torx Screws must be removed and Disconnect the plug.
2 - Disconnect Solenoid Valve #1
3 - Disconnect Solenoid Valve #2
4 - Remove Fuel line (bridge between both fuel rails)
5 - Remove Connector (Fuel Rail Sensor)
NOTE: Red arrow is the Coolant Line that is broken

 

How long will this take to perform?
Any helpful hints?
Excellent post to give the confidence I can do it.

 

The coolant line was brittle.

 

1 - Remove Bolts from Engine Wiring Harness, 2X, (Note. there is one on the Passenger side and one behind the Harness, towards the firewall). this will allow to lift the plastic wiring harness piece.
2 - Proceed to remove the Coolant Line from the Engine Cylinder Head and from the hose locate behind the wiring Harness.

 

Great job and very nice write up, Boricua!

 

@Gclasse:

That's very nice documentation, with the write-ups, clear pics, and the numbered labels. This project is beyond my desire, and possibly my competence, but it should be very helpful for those DIYers who run into this problem, and IMHO you're to be commended for the posts.

Just one other thing. In the first pic post, you wrote: "2 - Remove Throttle Body Hose (Flat Head Phillips Screwdriver)." What the heck is a "Flat Head Phillips Screwdriver"?

 

Upps, typo!!

 

Great write up. Looks like more work than the Cayenne but still doable.

 

no driver though...

 

Nice. Mine was still under warranty. I hear its difficult to get to

 

You need to take few things apart, but is not a big deal to be honest. If you like working on cars, few hours, beers and the rights tools, you will be fine! LOL

 

Ok, now what about the serpentine belt??

 

For that, the front bumper, radiator support and radiator fans must be removed. After that, you will have easy access to the serpentine belt!

 

If I have a repair (now that I'm out of warranty) I hope it is this, for $550, or something like that vs. the dreaded Timing Cover oil leak or the transfer case issue.

 

Gonna tackle this next week, my wife will be thrilled to get her car back.

 

Make sure to clean the intake valves during this job, get some intake cleaner spray as well!

 

I just had this done under my CPO warranty. 3 months left. The coolant disappears from the system and is collected on the underbody cover.

 

Mine just burst this weekend, luckily, I was right next to home. But I’m 3 months out of warranty and at 41k miles. Luckily, Porsche agreed to goodwill 75% of the repair. Brought my cost at dealer down to $450. Ugh, sounds like this is something to take care of if you notice coolant loss, which I did for quite a long time but didn’t bother to mention.

 

I had the same issue happened to mine. Coolant was low and I topped it off. Then the leak started consecutively within 2 weeks. After reading the threads, I decided to bring it to the dealer. The hose need to be replaced. $1600 for the repair due to 6 hours labor.

 

Always good to have another data point for potential issues (although year and mileage are generally useful to add, to such reports).

But more importantly: welcome to the forum.

 

Well, I wasn’t able to diy. MacanS is a 2015 with 50k miles. Out of warranty and a Goodwill already used on (PDK issue at 40k). I brought it to an independent shop and they were able to replaced the cracked T hose (driver side leaked) beneath the manifold for $780.

 

I’m about to find out what Porsche of Rochester charges for the coolant line. While on a trip to the finger Lakes 200+ miles from home…

 

Under $800, and very quick to get me back on the road.

 

Thanks OP! This was very helpful for me replacing this hose, which was very brittle but intact until I disturbed it while doing thermostat/water pump. Interestingly my local P dealership had a couple of these in stock, which leads me to believe it fails pretty often.
Very easy job, maybe 2-2.5 hours total from start to finish
