[DeTomaso] Heating problem

[Freddy Henningsen]

Mr Drew's right. as usual.:)
The leak comes from one of the tubes (closest to the engine room.) What I do not understand is how it is possible to cut the pipes? is almost impossible to see them. How do I get to the clips that hold the pipes?

  I am HOPING your pipes are okay.  Normally they only rust out at the very back, where they enter the engine compartment.

  To test it, I would disconnect the rubber hoses from each end (and throw away the ones in the cabin, as if the pipes are good, you will want new hoses there anyway).  Use compressed air introduced at the front end of the pipes, to blow out any residual gick that might be inside.  Then make sure there is no water visible outside the pipes, use rubber stoppers to plug the back ends at the engine bay, and slowly fill the pipes from the front, to see if they hold water.

  If there are no leaks, you're in good shape.  The problem was probably with the hoses.

  If there are leaks, you're in trouble.  It is next to impossible to remove the old pipes with the engine still in the car.  A friend in England did it by finding the metal clamps which hold the pipes to the body, and reaching inside and cutting them away.  This let the pipes slide to the rear, just a few inches at a time.  He cut them into many small pieces, sliding to the rear, cutting a short piece out, sliding again, cutting again, until they were fully removed.  

  It's not practical to replace these pipes with the engine in the car.  However, I see nothing wrong with using long lengths of rubber heater hose.  At least you will know the hoses are brand new and they should last for many years; when the time comes to replace them, for sure it will be much easier than what you just went through to cut out the old pipes!

  Hopefully it's not necessary...I would cut out the pipes only after I had exhausted all other possibilities!
