    B5 S4 Thermostat change

    Hey Guys

    got the usual slow warm up and in the cold not getting upto temp etc

    I am assuming the stat, as its got a new duel sensor already.

    is it possible to change without taking the belts off?

    any other tips etc?

    cheers

    Andy

    Apparently you can squeeze it out past the timing belt with a bit of wrestling, but i've never done one personally.

    My S4 is just in for a Timing belt change, new thermostat, waterpump etc. i nipped down last night to see the progress. i'd be incredibly surprised if you could get to the thermostat without removing the belt, it really is buried in the back of beyond

    Can i retract my previous comment, i spoke to Charlie at FA Ropers and he said it was possible but it was a pig. you have to loosen the front end so you can move the radiator etc forward and then when you put the new stat in there's hardly any clearance so it's a struggle to get the water gallery back in place

    Yep, someone on here has done it and posted up that it could be done without removing the belt but its a squeeze.

    I'd pull the whole lock carrier though to maximise access though.

    WELL!!!!

    Managed it........... changed the stat without removing the cambelt....

    the stat was stuck open, so never warmed up, was terrible especially in this weather... was using fuel etc etc etc

    dropped the carrier into the service position, left bank belt covers off. moved the belt carfully half off the pullies.

    you have to pry out the housing and its not easy..... plenty of room for error and to damage the belt if your not VERY careful.




    HAVING said that it took 3 hrs and now the temp is upto full in 2 miles........... so worth it................

    the main advice is to take care with the belt......... also a good opportunity to flush and replace the coolant.
