thermostat housing (genuine Toyota part
I’ve seen the carnage that corrosion and electrolysis causes to aluminum parts around the cooling system (maintain your coolant and make sure your engine grounds are clean and tight!!).
This new housing is clean, flat and willl seal again!
long one fits 22RE from 1985-1995 (sorry, the housing with the sensor holes has been discontinued and I don’t have any solutions for you)
short one fits 1983-1991 22R (again, sorry, the type with eh sensor hole have been discontined)
short one fits 1983 (only?) Celica carbureted (without sensor)
