Termostat A6 2,4 99 modell??

Hei,

 

A6'en til kona sliter med å holde motortempraturen så her må det nok byttes termostat.

 

Noen som kan hjelpe meg med å beskrive hvor termostaten sitter på motoren på denne bilen? Gjerne i form av bilder/spread...

 

En kort beskrivelse i ABC i bytting av termostat mottas også med takk.

Hmmm om jeg ikke husker helt feil, sitter den i fremkant av høyre topplokk. Regreim. bør/må demonteres for å få skrudd av termostathuset. Det innebærer jo da også at frontstøtfangeren må av og fronten stilles i serviceposisjon.

Sjekk temp giver for instrumentet først. Dette er en kjent feil...

Hvor ligger denne? Tempgiver til instrumentet altså.

 

Ser at oljetempen også beveger seg i takt med motortempen så jeg tror nok det er termstaten, men sjekker gjerne flere ting.

Den står på en flens bak på en av toppene, kontakten er blå med 4 ledninger på. tror det er høyere topp...

Special tools and workshop equipment required

 

t 2-hole pin wrench -3212-

 

t Locking pin -T40011-

 

Removing

– Remove front bumper → Rep. Gr.63.

– Move lock carrier to service position → Rep. Gr.50.

– Drain off coolant → Chapter.

– Remove poly V-belt → Chapter.

– Unscrew bolt -arrow- and remove tensioner for poly V-belt.

– Disconnect coolant hoses at thermostat housing.

Note

The toothed belt tensioner is oil-damped and can therefore only be compressed slowly by applying constant pressure.

– Turn toothed belt tensioning roller -1- clockwise in direction of -arrow- using an 8 mm Allen key until tensioning lever -2- compresses tensioner -3- far enough for the pressure piston to be locked with locking pin -T40011-.

– Insert locking pin -T40011- and release toothed belt tensioning roller.

 

– Pull toothed belt forwards slightly on tensioning roller and right camshaft sprocket -arrows-, but do not pull off completely.

dette er det som må gjøres. er litt jobb men er litt gøy å skru å da

google er også fint for bilder og andre ting. og ebay har sikkert tilsalgs en rep håndbok som er grei å ha. jeg fant rep håndbok til audi der iværtfall.
