[diesel_mercedes] Re : Thermostat Service

 


Yes ~ using a 6 point 1/4" drive socket , carefully remove the three 10MM ATF bolts then tap the housing edgewise with a big screwdriver's handle , it'll pop loose after a few whacks . no need to undo the top hose .

Once it's loose , grasp & raise the old 'stat whilst wiggling it , when it pops out , take a moment to wipe the crusty bits out of the entire cavity & sealing surfaces of both upper & lower housing , carefully insert the new 'stat and place the upper housing back into place , wire brush , dry off then *lightly* grease the three 6MM bolts , re - install and tighten evenly , easy does it ! they only need to be a tiny bit more than snug .
