thermostat

how difficult is it to replace the thermostat or should i just take it to a garage?

it depends on what motor you got

how comfortable you are with doing it yourself, and what tools you have at your disposal

but, its not very hard at all for me, just acan take a bit of time

a thermostat is easy and the part is like $10, just flush the coolent and take off the old one, then put a new one in, make sure u use the new gasket though

^ yup, follow the coolant hose to the inlet part on the block and take that off
