Just take off the top of the cabin air filter and take the filter out and put the new one in.

You need to follow the hose that comes out of the radiator into the motor and then take the hose off then there will be at least four bolts to take off as soon you take that off the thermostat will come out to. And you put it in the same way.

You need a computer and you could take your car to an auto zone and they will reset it for you free.
