My 2000 Boxster S has now revealed why it has needed a top up to the coolant header a couple of times.
I've found evidence of coolant leaking from the front left of the car but it appears to have a source further back than the two rubber hoses that connect from the metal Y pieces to the rad. Whilst they have very rusty retaining clips (thankfully not the 987 type connectors, those look awful once they get old) the hoses are nice and flexible and spring back into shape when squeezed. No evidence of weeping at either end. I can see a hint of moisture on the higher Y piece pipework about 50mm/2in inboard of where the pipe turns toward the centre of the car but further back from there is a goods smear of coolant on the under tray and under the body. It drips after running sometimes but not others...
Could is be a hose feeding the heater core/matrix? If so where does this tap off the cooling system and has anyone got any pictures of what the plumbing is like in this area so I can work out a plan of attack.
