    Please help newbie with radiator problem

    Hi guys

    I have had my Astra 1.6 mk3 for about 4 years, I have decided now that I want to start doing the servicing myself now to save me money and give me a new hobby. I have the Haynes manual which is very usefull but I am struggling with emptying out the radiator so I can change the thermostat. I dont know were the bottom pipe is that I need to remove.

    I know this may seem easy but I dont want to start taking stuff to bits unless I am sure it is correct. Please could someone direct me to where there may be a picture to help.

    I looked at the guide on this forum but I think it may be for a different model?

    Thanks

    Hi Fabos and welcome to AOC

    As you look at the rad from the front of the car (with you knees against the grill), look down the back of the radiator (engine side). On the bottom right hand side you'll see a fat rubber pipe about 2½" in dia leading for mthe rd towards the engine - that's the bottom rad pipe and the one you need to remove to drain the system. There should be a jubliee clip on there: undo the clip and waggle the hose off

    Thanks for the fast response.

    I have found a pipe fitting the description you gave, it is however about half way down the radiator, not at the bottom. The only pipes at the bottom are a silver metal with a torx/13mm nut.

    Is the correct one about half way down?

    Yeah that's the one - it's been a long time since I peered into a Mk3 engine

    Thanks for the help Ffoeg.

    I thought it would be quite easy but got confused because Haynes manual stated the hose was on the bottom of the radiator. Now I have dropped one of the cambelt cover bolts inside somewhere. I will have to spend most of tomorrow looking for it and finishing fitting the new thermostat.

    If I cant find the bolt I suppose I could be in the sh*t, as it could have lodged inbetween a belt somewhere.

    Anyway, have to go to work.
    Thanks for the help
