D24TIC - Coolant leaking into car

Singing Bird · Dec 23rd, 2007, 15:19

My 1996 240 TDi leaks collant onto the drivers side floor when put the heat setting is put onto hot, anyone know what is causing this? It's fine when the heater is left in the cold position. It does not have air con!

Hi,

If it is coolant, the only way for that to get into the car is via the heater matrix or one of the feed pips to the matrix..

Most likely is the matrix is going or on it's way out..

Very much a temp fix as the matrix is a very fine item - very narrow waterways etc and radweld can actually "fix" them by sealing the waterways up!!
Certainly a good temp fix if you know you are going to replace the matrix and fit new seals etc...

Have my 109,000 mile example for only £1000 if purchased after 6pm today or £100 if purchased before 6pm today. A great car in a great place.

I had this at about 97,000 miles, and I think it was the control valve thing for the heater. Sorry I can't remember what it's called. I was told by the main dealer that it's a very common fault with the 940. It happened about 12 years ago though so I'm a bit vague about the details. It wasn't a very big job to fix anyway.

Yes Roy is correct the most comon point for leaks into the driver's footwell is the heater valve. It is mounted on the firewall just above and to the left of the pedals (RHD car). From the symptoms (only leaks when turned on) I would suspect the valve first rather than the matrix.

Thanks lads

I shall have that valve looked at first! It sounds like that is the fella that is causing me leak.
