Need exact location and picture of coolant temp sensor on tdi vw jetta 2004 please Thanks

it is on the engine near the thermostat. it is on the engine near the thermostat.

Motor must be stone cold. Coolant is under pressure and hot. don't have pics but.. remove motor cover, air filter hose and etc. on back side of motor next to firewall on driver's side low down is sensor facing the back of car. Flat head screw driver to remove wire plug. next is a 'cover' over sensor. use same flat head screw driver to forcefully remove. Next pull C clip and remove sensor and o-ring. Can use plastic bag to catch coolant or try a vacuum on system by removing reservoir cap, mash water hose and replace cap. This will save some coolant loss. It will take several minutes for engine light to go off after replacement and running engine. Motor must be stone cold.
