A Nissan Altima thermostat will cost around $280-$320, depending on the region. You can go to your local auto parts store or online shopping mall to check the details, and choose the appropriate parts for replacement according to the local market conditions.
Nissan Altima thermostat replacement steps are as follows:
- Shut off the engine and open the front hood.
- Disconnect the negative wire of the battery. The purpose of doing this is to prevent the electronic fan from running suddenly during work and causing personal injury.
- Remove the plastic cover over the timing belt and the engine assembly.
- The location of the generator will affect the replacement of the thermostat, so the generator assembly needs to be removed.
- First place a drip tray under the car, then prepare to remove the water pipe and wait for the antifreeze to run out.
- Remove the faulty thermostat and install a new thermostat. After installing the thermostat, apply a layer of sealant to the water pipe.
- Install the removed water pipe, alternator and timing plastic cover in situ.
- Connect the negative pole of the battery, add new antifreeze, and then drive for a test.
Please note that the replacement of the thermostat needs to be carried out under the guidance of professionals, so as not to cause unnecessary damage or affect the normal operation of the engine
