    Default Siggy 2.0 T coolant leak!!

    Hi,

    Wondering if someone could help me please.

    During driving coolant check light comes up on dashboard. I stopped and noticed that some fluid was leaking by driver side front wheel arch. The coolant leaks only when engine is running.


    Looking at the car manual, I checked the coolant bottle which was completely empty.

    Please someone guide as I am novice.

    Also any idea, which color coolant is good for Signum 2.0T(04)?

    Many thanks,

    Signum04

    Before you start are you defiantly sure drip you seen was coolant?
    Only because if air con was on that sort of area the condensation drips from.

    on that side of the engine you have two options as far as i know.. the first is the drain plug could be loose in the bottom corner of the water rad. Second is the turbo coolant pipe runs around that side of the block, the front part is rubber and it joins a metal section midway where it then goes on to your turbo.

    You need the orange style oat coolant. I always buy the VX stuff, you can get it discounted on trade club at the dealers. Get 5 litres and refill with about a 50/50 mix of coolant/water and run your engine up and watch it, get somebody to raise the revs while you check every inch of collant pipe.

    btw when you top up the header tank you will need to pump the new stuff around the system to get rid of air locks. you can do this by pumping (squeezing and letting go then squeezing again etc etc) the coolant pipe the runs alongside the battery box to the top of the water rad. Keep pumping until its just liquid thats flowing back into the header tank (about 1 minute to be safe) then replace the header tank cap..

    Thanks critch & caveman_nige

    i bought vx antifreeze this afternoon and filled the bottle.

    the coolant sart driping although engine was not running. the coolant dripped with very low intensity as compared to when engine running.

    does this make any sense of what could be wrong

    its with engine running, its is right side of engine, close to auxilary belt area, been to few garages on saturday, all saying its water pump, i guess they just want to make money with three hour labour, none of them put on jack, its hard to see clearly without jack

    hmmm if your water pump is fubar'd then you're best to do a full timing chain kit and while your at it the balance chain kit..

    i can't see how it can be leaking from the waterpump but have not read of any others failing so far on these engines.. Benny would be good to ask on this but I have not seen him here for a while..
