My 2006 CTT (with only 17,000 miles on the clock) has developed a minor coolant leak. It's hard to tell exactly where the leak is, due to the tray under the engine, but do others here think this might be the pre-cursor to the dreaded coolant pipe failure? Thanks.

Best to check the coolant pipes - if they have not been replaced they should be.

They usually start with a small leak and then one day - boom they let go.

Thanks Loren,

I'm 99% sure that the pipes are original as I have all of the service records for the vehicle and they haven't been changed. Given how buried the pipes are, how hard is it to check them? FYI - The leak is definitely towards the rear of the engine...

I thought the coolant pipes under the intake manifold was something like 8hrs of labour??

Interesting the TSB says 100 TU (and 100 TU = 60 minutes). Seems low to me too.

Perhaps they mean just the pipes and not the rest of the disassembly.

I have a set of pdf files for the cayenne but am having trouble locating the disassembly instructions to get to the pipes. Any idea which manual this info is in? Thanks.

There is not one specific place for the instructions because (I guess) the fool who designed them did not think they would fail. There is a pictorial guide on doing the work your self either here or on Rennlist. From what I saw it is a PIA but doable. I paid $823 after PCA discount, the parts are $523 from onoine sources.
