Some riders have reported success with the Napa 535080, others say it is too tall to fit. YMMV. The thermostat is supposed to be the same as one for a couple of Honda cars - the 1973-1979 Civic (1200) and the 1976-1979 Accord. We'll try to find out whether that was the only thermostat used for those cars for those years (different engine options? Unsure).
Offset type with jiggle pin. Neck/seat 38mm diameter, ID 57.5mm, tangs 5mm each. 0.9bar or 13psi.
Don't forget the thermostat O-ring - part number 91302-657-000 for both Turbo models - available from eBay US.
