Hi, 300 tdi disco
I have tried all methods of bleeding the system ,
heater hose at back of the block,
connecting the heater hoses together to avoid poss matrix prob then bleeding,
running the car for long period with cap off ,
squeezing hoses,
bleed valve at rad and thermo,
all as suggested in this topic,
Still as i type the car is outside ticking over now for about 2 hrs and a constant strem of bubbles are coming up thru the exp tank,
Heater is cold, no moisture at exhaust, no evidence of water in oil, and the water pump is in good cond, thermostat removed!,
any ideas
Wade
