The 10mm nuts on my Echo were completely rusted. All that remained of the nuts was a crusty rust ring. For anyone else who stumbles in and needs to know: -The OEM part number for the 2002 Toyota Echo Thermostat Housing Stud is: 9012606019 -My thermostat housing studs DID finally come out for me with a Torx External Socket S5. I got the 6 piece Torx E-Socket set at Harbor Freight for $9.99. -You can use M6x1.00 20mm bolts instead of the OEM studs if your Toyota dealer wants to charge you an arm and a leg, and you ride your bike there and find out they don't even have any in stock.

Gasket goes around thermostat for those who are doing it

[@parkave2406]

Would the thermostat be able to cause a vacuum issue for the radiator hose?

[@DesignedinAustralia0]

Probably. Thermostat is one of the most important parts of the cooling system,if it does not open/release it can build up pressure and overheat or if it is stuck open your water pump can fail prematurely.

Did you bleed the system after? If so, how?

[@DesignedinAustralia0]

They have a plastic drain tap at the bottom if i remember correctly or remove the bottom hose.
