Porsche 997 and 981 front coolant hoses. What goes wrong? 

We see a lot of cars that need a substantial amount of work doing but still drive so owners are oblivious.

I must be honest and say that we've been quite busy doing other things of late. The engine is back together, the car has been fully stripped and is in primer, I've had the brake calipers overhauled, need to get the suspension components sorted out and a few other jobs. The next video will be a trip back to see Steve at Jaz to go through what was done to the engine.

No worries

Thanks !

Thanks for that. Hopefully you're all sorted for a while now.

Glad you found it useful

As you say these are potentially 15 year old plus cars now

PPI on Porsche pays 1 hour. Nowhere near enough to drop all underbody panels and look deep inside Sadly.

Hi there. Sorry for the delay in responding. Yes, 987 Boxster / Cayman will be the same.

Not really, it isn't a massive job to drop the front subframe, it isn't like dropping the gearbox to do a clutch. Whilst you're in the vicinity it's worth checking the coolant radiators and air conditioning condensers.

There will certainly be a correlation between climate and corrosion. We also use salt on UK roads in winter which won't help.

@@911virgin8 maybe there are enough cases that we hear about them in the parts of the country where we have cold, salty air or something. But here in the US we have a variety of climates, and up north they frequently salt the roads. Still, haven’t heard of any cases. Just odd.

@@K1dPhresh1 Very strange indeed. It is possible that US law dictates using a different type of antifreeze but I've not hear of that. One of life's mysteries.....

@@911virgin8 Indeed!

Across the pond corrosion ! I don’t drive my car in the winter so hopefully not having this . Currently tracking down coolant loss

Yes, it's the same set up so potentially an issue. In terms of why, I guess partly a materials issue and partly the environment. The latter will mean that not all cars suffer to the same degree. Judge it on an individual basis, it's easy enough to spot when the car's up on a ramp.

Hi there Stephen. I suspect the vaseline would melt and run off. It gets to around 90 degrees centigrade when up and running. We do use a rubber grease when re-assembling which helps a bit and the pipes have also been re-designed which may help delay problems moving forwards.

​@@911virgin8 vaseline is petroleum based and will react with the rubber, you'll be better off with silicone grease, which has a much higher temperature range too, typically 200*C+

The 996 is quite different to a 997 in that it doesn't use snap connectors other than for the radiator it's self. Before you get too excited though whatever you might save on coolant hoses will be more than accounted for on the 996's brake pipes. The right rear caliper feed pipe from the junction left hand side 3/4 back which goes over the top of the gearbox is a particularly tricky little blighter!! Make sure you check those brake lines whenever you're doing a clutch. The perfect time, it will save you around 3-4 hours labour.

Labour wise it's about four hours plus a 4 wheel alignment. We charge £85 per hour. The hoses are from Porsche, I think they total around £250 off the top of my head, possibly a touch under that.

@@911virgin8 Thank you good to know

You would see leaking / corrosion around the hose joints and make a call based on that.
