hi folks just got home and there is a guess water traill to parking space and a foot wide puddle underneath car right in middle at rear of engine any ideas :'(
-
If clear water and no taste of coolant then perfectly normal side effect of air con working as it should :y
If it tastes of coolant then usual suspect is hbv or associated plumbing :y
-
to tell you the truth dont know if aircon was on just done school run never paid attention whether it was on or not if i go start now and put aircon on is there away of finding out if culprit?
-
Taste the puddle, the cause will be obvious :y
-
tastes disgusting take it anti freeze
-
any chance any member mechanics around milton keynes? as marks dtm will vouch i aint mechanically minded and he just a bit far away for this

Sounds like the good old heater bypass valve, just done mine. Cheated and got one of our contractors mechanics to change whilst I went home and put my feet up :y

-
Interested to know what the results of this diagnosis is as i have an identical issue.

I assume this has just started happening in the last few days?
Does the leak vary dependent on climate setting?
-
As Marks DTM suggests, if its leaking when climate set to HI (for eg), try it with climate set to LO, or vice versa. This usually points to HBV, about £30+VAT from dealer, trade, although avoid the scumbags at Crownhill (V4, between H5 and H4). I'm told a new dealer has recently opened at Kingston, near the BP, on the way to the M1 Jnc 13. No idea if its Crownhill moving, or a separate dealership.
I'm in Brackley, on the Bucks/Northants/Oxon border if you need a 2nd opinion, or help.

hi mark etc so today filled up reservoir it was about 2 inches from max so filled up to just below line drove to work with aircon on and set at 19 i tried heat on and then on low temp went up a bit when heat on to around 90 then back down to 85 when i got to work it has lost about a inch in reservoir.
drove home tonight and still sitting roughly same and no puddle or trail when reversing into space also checked foot well that dry. think i need someone to have a look so if you theboy are free over weekend can you have a wee look? would help me out need car for my new job just started thanks :)

will try in morning hard day need to sit down thanks :y

so the update, after initial leak which lost me about 2 inches in expansion tank i filled up and since then nothing. have had aircon on at hi and ran for about 15 mins then put on low for same i then drove back and forward work 2 days still ok weird or what?
will keep a eye on it but thanks to all :y
-
You'll most likely find it all escapes at one temperature setting. Try a different temp each day until it leaks...
The only consistency with HBV failure is that the temp is always different ::)
-
Symptoms are typical of HBV.
I would buy a new HBV anyway so that it is in the car ready to fit when the old one fails completely.
-
ok i reckon will buy one just in case and thanks again :y

theboy
hi would you be able to have a look if can get over to you this weekend if you are free? would appreciate it thanks

Had a gander at this today, although buggered if I could get it to leak, using the modified cap and pressurising to about 10psi method :-\
Valley is bone dry, no hint of leak from stat, cooler plate, bridge, HG (to outside of block). Good job there, Mr DTM :y
Bits of radiator that are visible all looked good, as did rad hoses. Curly hose from bridge to HBV looks good.
Tell tale signs ("rusty" look) of a leak around HBV, which would fit in with brian36's diagnosis of where he's seem coolant under car, and with his observations with the climate settings within the car.
Disappointing I couldn't 100% prove the leak, but given what I've seen, the HBV is what I would do :)
