Draining cooling system

[clift_d]

You could try jacking the rear of the van up. Also open the bleed screw on the radiator and turn the dash heater valve to hot. There should be another 13 or 14 litres of coolant in there to come out.

Ok, jacked the rear up, opened bleeder screw on radiator, heat on, lid off on reservoir and expansion tank both hoses off from radiator, still only around 3 litres coming out. What the heck am I doing wrong??

Stick your mouth on the rank and blow

Sometimes you need to tilt the long coolant pipes downwards.

You will figure it out.

Thanks for the advice!

I never managed to drain more than 9-10 litres but with a couple of drain and fills I’m sure it will do. This was definitely the least enjoyable operation so far on my T3… impossible not to make a mess . Feels good to have done it though as the coolant probably hasn’t been changed for at least 20 years. Again, thanks for all the input!
