Slight leak at front radiator hose


Recommended Posts

My local Porsche dealer identified a slight weep at the ns front crossover hose under the wheel arch on my 2010 987. They have quoted almost £850 to replace it. Does anybody know why this is so expensive? Is there something special needs to be done which bumps up the price? I can get the hose for around 30 quid online but maybe its not as simple a DIY job as it looks? Any advice would be welcome.

It’s a royal PITA job that’s why.  The correct way to replace involves lowering the subframe, it can be done without doing that but that makes the job quite tricky.  
 

Is this an OPC quote or an independent specialist?  Does sound a bit pricey for a decent indie.

For comparison, A ‘typical’ price from a good indie for all the front hoses and pipes replacing is ~£600

As Nick says, it's a fiddly job.  I did mine about 3 years ago and the front hoses and aluminium crossover pipes were about £220. 

 

To do it properly you need to lower the front of the subframe for clearance which is actually very straightforward but does require a geometry alignment afterwards.  I did it at the same time as some suspension work which needed a geo anyway.

 

I produced a detailed write-up so let me know if you want to give it a go.  While it's fiddly, I'd take this any day over sorting the exhaust studs!

It sounds like its a level above my DIY skills, and I probably don't have the necessary garage kit, but if you can send me your write-up, I'll see if I fancy tackling it. 

Cheers.

Or better still, post your write up here!

 

I did it a few years ago without lowering the subframe on a 987.1. It was like training to be a gynaecologist!

😱👀 Fricking hell that is some write up. 

Thanks for sharing 😁

 

No problem.  I wish I'd taken photos along the way!  It is apparently possible to do it without disturbing the subframe but I knew I needed to get the geo sorted after the suspension work anyway.

 

It's a few years ago and my memory is a bit fuzzy but there's a plastic supporting clip for the crossover pipes which I mention in step 20.  I don't think I would have been able to get the pipes back into the clip without the extra clearance. 

 

I've heard of someone else doing it without touching the subframe by cutting the crossover pipes up to get them out and using cable ties instead of the proper plastic support clip so I guess that's an option if you're happy with the compromise.

Thanks - the problem is finding a good indie Porsche specialist in NE Scotland.

get yourself down to Peter at Motortune in Shotts - plenty people from the NE travel down for his services

I did it to mine without dropping the subframe as I mentioned earlier. Don't try it. The bits you need to get to behind the subframe are partially hidden, so you can see, but not touch or touch but cannot see. If you see what I mean.

 

Horrid job!

 

But what a great write up!

Having done this I can agree with all the comments. The only thing I will add is that it's worth buying all of the pipes for the front end before you start the job and return any you don't use afterwards. It's a pig of a job and I've no clue how it could be done without dropping the subframe. Having said that, if you lower the subframe on the bolts but don't remove them then I'm not sure why everyone says that you need to get it aligned afterwards as nothing is moved out of alignment. As it happens I did get an alignment check done a few months later and everything was fine at the front, furthering the notion that nothing had moved.
