How long does it take to replace the thermostat on a Mazda 3?
Pull the thermostat (the bolts suck to get to, make sure you have the right size sockets and extensions, etc.), replace it, and put it all back together. Add coolant to the reservoir to replace what was lost when you pulled the thermostat (it will give a nice little gush). Should take less than 2 hours.

Take a socket on a ratchet and attach to the “bolt” on the passenger side of the tensioner and push toward the rear of the car to loosen the belt (maybe toward the front, I can’t remember.

You don’t need to cut the AC Belt to do the thermostat. You only have to cut the AC Belt if you want to replace the serpentine belt – a whole different topic. You only need to take the serpentine belt loose to do this job. Some have claimed to have replaced the thermostat without removing the belt or the tensioner.

How can I loosen the hose on my thermostat?
The hose clamps can be loosened by grasping them with pliers on the tabs. This will loosen the clamps and allow them to be slid further down the hose a couple of inches in order to clear the flanges on the thermostat. The hoses can now be coaxed off of the thermostat hose flanges.
