I don't know if the cases are different but I have a 2.1 case in my '85 with
all the 1.9 bits. I managed to change the thermostat without dropping the
exhaust by taking off the bolts holding the water pump on and moving the
pump out [that's towards the driver's side of the van] enough so that the
thermostat clears the exhaust pipes below it. Worked OK.
