Hi I think my heater matrix has gone, I've searched the internet and find no mention of V40 matrix - does anyone know FOR SURE if the S40 from the same year is the same matrix? 1998 V40 1.9D Has anyone changed one on a v40 - any usefull hints, tips?? The cooland is disapearing very quickly (within 30 miles the rad is nearly dry) so I've clamped the in/out hoses from the engine to stop the coolant going through the blown matrix - this morning the water temp gauge went up as normal so I assume it is ok to lock the matrix off - any comments?? Hope its not too cold and raining theis weekend........... Thanks in advance for you assistance Nugget
