Just done it my o ring was a bit different to the old one the old one went on outside my oring had a slit in it to go all round the circumference of the stat and half sits on inside and half sit on outside u hear of that before
 
1.9 tdi Leon 110 brake so heaters working fine gauge going up if I take it for a drive it should open the thermostat everywhere else is hot apart from thermostat hose
 
That o ring that come with it seems to be fine it's not leaking from the housing. When the thermostats in does it matter which way round the top end goes I put it so that the bar was like 12 o'clock to 6 oclock
 
Yeah I read the guide then I read someone else's and there's put me off lol about having to have flanges and all the rest of it.

lol when you do try it your self dont try and pick up the bolt when you undo it,about to bolt it it all up just when the bolts drops i try and pick it up and:cry: its gone lol ....(note to self rem the magnetic pick up )
[:@]...............i know i know
 
Just turned my engine off in a practice panic thinking that it was pissing out some where but really I think it was coming from the undertray.

Thanks for ur help mate appreciate it can't believe how easy it is undo two bolts take a stat out put a stat in top up with g12 sorted lol quality thanks agen mate
 
It is leaking coolant when I drive Could it just be going out the overflow of the bottle
 
It s left hand side could it be the stat

i know from my own leak that was pretty small nothing major but still leaking abit and i was putting this down to the seal being old and wrecked like,after taking it off it looked pretty fooked.
when you changed the stat did you dry off the area off?(underneath the pipe)if so then i would of checked when warming it up checking for leaks,and if you did undo the bottom hose under there also but tbh it should all be tight once back on....
