leak from behind rear wheel

hi its probably the pipes that go to your rear airconditioning unit

parts cost £437.35+vat and about a days labour not a good or cheap job unfortunately

We have now got this problem sorted but I thought it might be worth putting a post on, as I am sure some other Pathfinder owners will come accross this problem at some point.

It turned out to be the heater matrix pipes leading to the rear matrix.  At Manufacturer Nissan place small pieces of rubber hosing around the two pipes to stop them banging together, but over time these rubber pipes collect dirt and water and corrode the pipes beneath, which then causes antifreeze to leak from the pipes.  it is a fiddly job to do as the pipes pass over the axle but it is possible, we used copper pipes to replace the pipes that had corroded (you can't use rubber hosing as they pass directly by the exhaust)then use small pieces of rubber hosing and jubilee clips to connect the old pipes to the new copper pipes.  I hope this helps anyone having the same problem!

Hello again. Have been to dealer now and had the problem looked at by service manager. He confirmed problem is corroded pipes to rear heater/air con unit. However, he says they have checked with warranty company and air con is covered but not pipes! I am going to contest this as my warrnaty booklet says air con is covered and dosen't break it down to components. I'm sure I have read somewhere else about this problem with Pathfinders so I would like to find out extent of problem. Has anybody had same problem or knows where I can get more information on it?
