#1: Missing Coolant Author: 206HdiGti, Posted: Thu Dec 27, 2012 3:44 am ---- I've done almost 4000 miles since my coolant change. I've used proper pug stuff when it was changed.
I've had to top it up three times however since changing it. The car doesn't overheat, it just asks me to top it up.
I'm not considering this as normal behaviour. I cannot see if its dripping as the big cover is currently bolted on.
It lost some of a period of two days where the car wasn't used or even started, so i'm expecting there to be a leak somewhere.
Before anyone says 'I told you so' because of the model of engine/car, coolant leaks happen on all cars, so please helpful answers.
Any idea where to start looking?
Cheers

Later ones have a normal hose and jubliee clip which is reliable. Earlier ones had a metal coupling held in place with a circlip. These can leak.
I think the later radiator hoses don't use jubilee clips but couplings built into the hoses. My wifes 207 CC uses these and on the reservoir if I move the hose I have hear a schlurping sound as air enters the system! I top hers up with about 100ml ish once a year.
My 206 never lost any coolant and my Jetta doesnt ever drop either.

I Can always depend on your for very good advice!!
I will be taking the undercar cover off later (if it stops bloody raining!!!!) when I get home from work, as you just cannot see anything in these engine bays any more!
If it is that, I can just replace coupling with proper pipe and jubilee clip it?

#6: Re: Missing Coolant Author: Timon2210, Location: PalestinePosted: Thu Dec 27, 2012 5:19 pm ---- well the best way to make sure where the leak is-If you have any-is to use the air pressure method,which mean you put high pressure air in the cooling system,and the weakest point ,even a hair line crack will be seen with coolant going out from there
#7: Re: Missing Coolant Author: 206HdiGti, Posted: Sun Dec 30, 2012 8:14 pm ---- When the coolant was changed we used a vacuum type system to suck all air out before putting it all back in again. When that happened it would have shown up a leak.
It must have happened since the coolant was replaced. I haven't had chance to look yet as weather has been bad
#8: Re: Missing Coolant Author: 206HdiGti, Posted: Sat Jan 05, 2013 1:05 pm ---- I have a leak at the end nearest the oil cooler in the radiator. Any idea where i can get a new one?
#9: Re: Missing Coolant Author: kandlbarrett, Location: SwindonPosted: Sat Jan 05, 2013 2:08 pm ---- Plenty on line between £45 - £60 excluding delivery.
#10: Re: Missing Coolant Author: Deckchair5, Location: Bath UKPosted: Sun Jan 06, 2013 3:19 am ---- When the coolant doesn't level out after someone says they have done a coolant change then I would suspect ineffective bleeding on the refill. A leak doesn't start because of a coolant change but ineffective bleeding is very high on the probabilities. A coincidence that you suddenly get a leak that you can't see after changing the coolant? I wouldn't think so
First thing I would do is set about rebleeding it using the normal methods as detailed in the manual
#11: Re: Missing Coolant Author: 206HdiGti, Posted: Mon Jan 07, 2013 4:55 am ---- I saw it dripping out the bottom of the radiator
#12: Re: Missing Coolant Author: macca1411, Location: Westhoughton, LancashirePosted: Mon Jan 07, 2013 6:26 am ---- We used to drop a couple of raw eggs (works better than Radweld) into the radiator to plug a leaky hole
Leave the engine to run for a while and the egg is forced into the hole from the pressure . It cooks and seals it like a rubbery grommet. It's only supposed to be a make do and mend solution but I've known it last for a while.
Never tried it with an expansion bottle, so I would try to read up on it more before trying it.
#13: Re: Missing Coolant Author: 206HdiGti, Posted: Mon Jan 07, 2013 6:43 am ---- I'm just going to replace the radiator.
I have heard of that method, but I do 500 miles a week, cannot trust eggs for that.
Rads are readily available and it looks to be an easy job so i'll get the whole thing done properly.
Has anyone got the actual sizes of the radiator for my model?
Cheers

Bodge. Some cooked eggs won't stop the a**e falling out the radiator if it's rotten.
