318touring Posted April 11 Report Share Posted April 11 (edited) I've searched this forum, and used a couple of references posted here including the Design 911's crossover pipe kit. In their kit they have included the 2 long hoses included, which is around 100 quid each, when added together made up around 40% the cost of the whole kit. My question is, do I really need these 2 long rubber hoses as the failure points seem to be NOT at these hoses? What do you all think? I have highlighted these hoses in Red for clarity in this picture taken from Design911's site. https://ibb.co/7j2tmPx Edited April 11 by 318touring Quote Link to comment Share on other sites More sharing options...
318touring Posted April 11 Author Report Share Posted April 11 BTW, this is the offending part(s). It is on the right hand (driver) side of the car. You can coolant pooling under the hoses, unsure which hose/part exactly that has failed. https://ibb.co/9Z0ZfZk Quote Link to comment Share on other sites More sharing options...

May of course depend on factors such as cost and whether you're paying for the work or doing it yourself. NB if doing it yourself parts may well be cheaper from OPC or Spyder Performance. And have you seen the detailed video on YouTube? Quote Link to comment Share on other sites More sharing options...
Mattman42 Posted April 11 Report Share Posted April 11 My mechanic told me to leave well alone unless there were signs of leaking - generally its the front pipes that usually fail, not the long ones, but some prefer to swap out the whole lot if they are doing it themselves. I had the front ones replaced on my previous car for around £400 all in - my current one had already had them done. Seems that they start to leak around 10-12 years old rather than mileage. There are a few threads on here where people have DIY'd the job - some have been clever and found ways to avoid dropping the front sub-frame completely - its way past my level of car DIY Quote Link to comment Share on other sites More sharing options...
318touring Posted April 11 Author Report Share Posted April 11 I'll most likely, definitely, outsourcing this to my local garage with detailed instructions. Fortunately they dropped the subframe last year when replacing the left coffin arm. I'd like to not spend the 200 quid for those pipes if not needed. I'll check pricing around since I'm based in New Zealand. I've found cars245 have consistently provided the best overall price including shipping.

That is a lot of unnecessary work unless the inboard bolt was corroded in place and they had to get it on the bench, even then normally possible to sort without getting the sub-frame off...

Jono_h Posted April 11 Report Share Posted April 11 I noticed that you can get the 4 flexible hoses to the rads for about £80 - it seemed like a good idea to replace them almost as a maintenance item. If you can get them changed before they corrode and damage the aluminium / plastic pipes you’ve saved a whole load of work. Next time I’m under mine I’m going to have a look to see if I’m too late.

If I was going to pay for it, I'd save up, do the lot and get the parts from Porsche not a third party. Quote Link to comment Share on other sites More sharing options...
Paul P Posted April 11 Report Share Posted April 11 Just had all the front ones done on mine. 987.2 - 2011 car. Done (mostly) under Porsche extended warranty - I paid for a few parts that were not ( or couldn’t easily be made to ) actually leaking.

Yup, corroded and they couldn't get it off. This is not a Porsche specialised garage hence that would be the 1st time they work on a Boxster. My OPC wanted NZD404 approx. 200 quid to investigate my coolant leak ...... Quote Link to comment Share on other sites More sharing options...

It'll take them about a month to source the parts, but it's not urgent and the car can just sit in the garage. https://ibb.co/YBLBrx7 Apparently the leak has been ongoing for a while, pretty wet down there. Investigating whether there is anything needing attention by taking the liners and undertray off. https://ibb.co/wsk33hL Quote Link to comment Share on other sites More sharing options...

My local indy quoted well over 1k ☹️ My car is 13yrs old this year so feel like I’m on borrowed time with them now! Cheers Quote Link to comment Share on other sites More sharing options...
318touring Posted April 18 Author Report Share Posted April 18 (edited) Now on to the type of coolant I should get? Based on research, the Red one with Si-OAT will be suitable. Something like this? Keeping in mind that I live in NZ so different product availability. https://www.repco.co.nz/oils-fluids/engine-oils-fluids/coolant/penrite-red-oem-approved-coolant-concentrate-2-5l-coolred0025/p/A1270781 or this one https://www.supercheapauto.co.nz/p/nulon-nulon-anti-freeze-anti-boil-pink-premix-coolant-5-litre/678275.html?cgid=SCN010706#prefn1=adArticleType&prefv1=Coolant Concentrate|Coolant Premix&srule=Price Ascending&start=39&sz=60 Edited April 18 by 318touring Quote Link to comment Share on other sites More sharing options...
