- Porsche Cayman Boxster 987, 911 997 front coolant crossover pipe replacement. In this video, I show you how I changed my front coolant hoses on my 987.2 Cayman S. The two on the front left, and two on the right, as well as the two aluminium crossover pipes. I also replaced two smaller hoses which connect to the long aluminium pipes that run up the centre of the car. I also replace the seals on the hoses from the engine and two hoses which connect to the heater matrix.
This is quite a long job and requires some patience. Firstly you need to drop down the front subframe, this is easily done but you will need to get the wheel alignment checked afterwards. You can’t change these crossover pipes without dropping the subframe, trust me I tried. I read somewhere that some did, and all I can say is, there’s no way it would of went back together without something being broken or bent. It’s not worth the hassle, time messing around, so don’t even bother. Its 8 bolts to drop the subframe.
After replacing these hoses you will need to refill the coolant system. It’s takes approximately 15 litres of water/coolant depending on how much you lost/drained.
When bleeding the coolant system firstly open the bleed valve which is located next to the coolant reservoir/bottle. Open the bottle and fill with coolant, once full put the cap back on and then fill from the coolant filling cap next to the oil filler.
Run the engine and keep topping up the coolant, you will notice the engine temperature fluctuating, keep the heater temperature on high and keep checking it. You will need to rev the engine to about 3000rpm, keep revving and topping up, keep a count on how much water you have put in, this will give you an idea as to how much there’s left to go.

Great vid. Starting my 987.1 Boxster tomorrow morning. Luckily I have a 2 poster at home. Yours looks like it has spent a life outside. Mine must have been a garage queen as there is 99% lack of rust. Only corrosion on the pipe ferrules.. I will have the alignment done on completion as I track my Boxster..Good shout. Well done.
Your power steering lines look really good , they can be bad fo corrosion too and really big job to replace.
Very informative and detailed. Will be using it step by step to do my 997. Apparently the 997 takes 30+ litres of coolant. Got to invest in a quickjack!!! Thanks
Hey, yes it’s amazing how much coolant these things take. The Quickjack is so convenient, wish I bought it sooner, you may need to release some of the securing nuts for the under trays before jacking up tho as the may be difficult to get to with the quickjack in the way. Also, just drop the front subframe, there’s no point in messing around and if you’re changing all the pipes, just cut the rubber hoses off to save time. 👍🏼
Great vid! Thanks, I’m just about to do my boxster pipes, your detailed vid has helped loads! one question, did you take off any suspension parts at all, I’ve borrowed a big hyd ramp to get her up a bit higher, unfortunately my coffin arm bolt are seized solid, let the fun commence.
Hey @@simonparks5784 thanks for the comments, no, didn’t need to remove any suspension parts, only release the anti roll/sway bar. You will need to drop the subframe though. All the best 👍🏼
Great job!....carried the same job out on my 997 4s last year whilst i was doing the a/c Condensors.......what a complete and utter bad design by Porsche, i.m astonished why the system has to be so complicated with such a mixture of plastic, aluminium & rubber . Changed all the euro clips with jubilee clips.
Also invested in a vacuum pump to refill coolant as i didnt want any air locks. I reckon this is a diy job but a ramp would help.
i commend you again for keepin your cool!!!........oh yes i've just purchased a 2005 s Cayman with good hoses!!! so i'm subscribing and following.....cheers.
Julian, thanks for the comments 🙏🏽 a vacuum pump for refilling the coolant is a life saver, great bit of kit, otherwise it takes a lot of patience. And yes a ramp would make this so much easier 😄
Well done! Excellent talk through and good visual references.
I’ll look to see if you have done a video on replacing CS 987.1 COOLANT BOTTLE, because I have a tiny leak back there somewhere near the reservoir. Porsche service had replaced my water pump several years ago, and immediately afterward I smelled coolant, so I took it back to the dealership. They said could find nothing wrong. of course. Then I put the car in storage for seven years. I just put it back on the road the again. Yup, there’s still something wrong back there. That sweet smell of steaming coolant after warm up.
pressure test indicates no leaks. I replace the radiator cap which the dealership had not done but that seems to make no difference. There are no drips, but that smell is undeniable. I’m having trouble finding the procedure for removing the reservoir bottle which does not want to come out. It looks like possibly some of the top end of the engine on the right side needs to be removed. 😖
Hey, thanks for the comments, unfortunately I’ve not removed the coolant bottle so can’t advise on that, I’m sure I have a workshop manual somewhere so I’ll check. You might need to take out the inlet manifold. Hopefully you’ll get it sorted 🤞🏼
@@GarageTechAutomotive Thank you for the reply. I saw someone else’s (poorly done) video where they had removed the Reservoir bottle, but didn’t show it being done, or mention how they did it. Only that it was very difficult to get it out. Worse, they never showed the new one going back in.
Thanks for this! Word to the wise though, WD-40 degrades and swells rubber so it is not recommended for coolant pipes.
very well documented. ridiculous design on the cross over pipe ends. would have been so much easier if they just used "slip over" fittings that used hose clamps. The aluminum and plastic pipes were always going to be OK. It's just the rubber hoses that might need to be replaced. Anyway, again, good job.
Great walkthrough and loving your attention to anti-corrosion husbandry. Were you an aircraft techie in a previous life? 😜
Hey, thanks for the comments, I was an auto tech many years ago 👍🏼
Hey, awesome video, helped me a lot in determining which parts I will need to get. Not as brave as you though, I'll get the lcoal garage to do the replacement.
One question: which type of suitable coolant I will need to get? Would appreciate getting a steer on this. Thanks
Hey I used the genuine Porsche G40 coolant, you can get other brands but just make sure it meets the Porsche specifications 👍🏼
Great video; very useful!
Thanks for good video! I need to do the same work on my 987.1 Cayman S. What is your axle stand setup? What do you use as lifting points? Could you make a video to show how you lift your Cayman on axle stands and any tips/hints?
Hi Simas, I first jacked up the rear at the jacking point and then used an axle stand under the rear subframe, I then managed to lift it a bit more to get an axle stand under the other side on the jacking point, and then remove the other jack and jacked the subframe area back up slightly to get the other axle stand under.
The front was very similar the car is actually very stiff so when jacking up on one side it actually lifts the other side high enough to get an axle stand under and then i used the trolley jack under the wheel, make sure that the brakes are applied, then lift up just enough to get the other axle stand under the jacking point. I’ve now got a quickjack which is 100 times easier than messing around with the axle stands. good luck 🤞🏽 if you need any more advice, let me know
@@GarageTechAutomotive thank you for info. What kind of axle stands do you use? Are they a good match to the jacking pads under the chassis?
I was tempted by quick Jack but it costs a lot. I can get low trolley jack, axle stands, and all replacement parts for the cost of quickjack. Maybe in the near future!
@@simasjermosenka6870 I’ve got a set of axle stands from Halfords, link below. they’re 3 tonne stands with fixed feet. The top is wide with a u shape so fit the jack mounts which are a round rubber pad on the cayman well. I’ve also got a cheaper set which fold up, they’re not as sturdy as the others and the top isn’t as wide. The wider plate is better as you can attach your own rubber pad if required.

Impressive video....I like wrenching, but this looks very intimidating. Do you think the corrosion is due to outside environment? (Do they salt the roads where you live?) Or is that just the o-rings slowly failing and leaking?
Hey, combination of both, as you will see this on the hoses which connect to plastic pipes, so the seals do start to leak. they salt the roads here in the UK so that doesn’t help, moisture gets in between the steel and the aluminium, then corrosion occurs. The salted roads and wet weather speeds up the corrosion.
