The thermostat in 2000 audi A6 is bad. How to fix ?


Hi,
The thermostat is located in a housing, mounted on your engine with the top radiator hose attached. It is relatively easy to replace.
Be sure to put the new thermostat in the correct direction (notice direction of old one before taking it out). Also, be sure to clean the old gasket from the housing and be careful not to break the housing... many are cast aluminum and overtightening a bolt can easily create a headache. :o)
Hope this helps... Good luck!

how do I change the thermostat on a 6 cylinder nissan frontier truck


Hello Wayne...the thermostat on your truck is located on the engine under the thermostat houseing. It is positioned in a fairly tight place. It can be replace with regular hand tools, ratchet extension, swivel socket and wrench. Follow the radiator hose to the thermostat houseing to locate. I suggest you replace it with a Nissan thermostat, they seem to last longer than an aftermarket, and come with a new houseing. Enclosed is a picture of the houseing you will be removing.
Make CERTAIN you install the new thermostat in the correct position...if installed backwards it will NEVER open and your engine will overheat in minutes possibly causeing severe damage.
Good luck..i hope this helps, please take time to rate me a fixya.
