So, in the olden days, we used to take the thermostat out of the Morris Oxford, Ausin A35, put ut in a saucepan of water and heat it up on the stove. Just south of boiling, it should start to open.
So, here we are with an E46 thermostat housing/thermostat/sensor, we disengage the actual thermostat, (most likely the first error) from the plastic housing and drop it in the saucepan.........didn't open BUT, due to the way it works, it probably wont open BECAUSE I now think it dependent upon the thermostat body/cage being held by the plastic housing.
Now, we attempt to refit the thermostat, back on to the long SS bar/pin BUT, it will only go back on the bar/pin about 1.50" (1.00" less than it needs to).
I believe I may have allowed the wax inside it to run where it doesn't belong and said wax is now preventing me from reinserting?
Any thoughts please, thanks.
