Model:1100 special
Year: car 1980 BUT ENGINE 1977

Description of problem

drove to the mot last week (about a mile) and when i parked up there is steam pouring out from the over flow pipe down the side of the rad.

anyway ive taken the thermo stat housing of as the engine had been sat for a while and it could do with a new one.

and i found this



wax stuff in rad..


underneath stat



what is it and has it come from the rad or the thermostat?? or elsewhere??

Looks like the remains of radiator seal stuff... horrid stuff.

If I was you i'd flush the whole system with 50/50 white vinegar and distilled water - bring car upto temp then drain and flush with clean water.

Check if the thermostat works it's not called a waxstat for nothing.

yeah i soaked the rad in boiling water and vinegar for a couple of hours.. and it seams to have clear most of it.

also replace the stat with a new one, so im hoping the rad is saveable.. ?

Looks like the stat has disintegrated.. the wax has come from inside the stat itself, that's how it works. When the coolant heats up, the wax expands which is what makes the thermostat open.
