Mine was doin this mate as u might know still in garage now waitin for a cylinder head :-( after payin out for a head gasket and new rad it

Is there presure in the cooling system ?.

 

Is it just using/loosing water or is it blowing water about or is there a temp problem?

 

There is some pressure in the cooing system definitely not excessive, no temp problems except the heater stops working when the water level drops. There was a slight leak where the pipework goes into the cylinder head, cured that.
Hopefully not a cracked head....

 

I'd try run a pressure test on it before doing owt major.
Certainly bypass the egr cooler if ya can.
Have you lifted the carpets ? Check and make sure heater isn't leaking, the d40 carpet underlay holds water back well.. May not show damp on the carpet top.

 

Good idea biggi, will have a look see.

 

Mine was presure tested turn out to be ok 4 times when he stripped it he tested it again was goosed.
You need to think how the presure getting into the system I mentioned the egr to the garage he said he had tested it was fine.

So it down to him now to foot the bill as he has not fixed it twice.

You could also bypass the heater matrix to try that instead of stripping down the dash

 

Shall we do things methodically guesty instead of just it could be this it could be that. The moron that has yours is clearly incapable.

 

Have you checked your oil level, I always check for water in the oil and oil (and exhaust fumes) in the water but I drive a d22 so it comes with the terrortory :lol: :lol: :lol:

Did some digging around this morning. It does seem to be a leak around the thermostat area. Really difficult to find the source being tucked under the turbo.
Will find a garage to pressure test it next week.

 

Shame your not local pal, I have one.
Keep us updated :awesomework

The pressure test needs to be monitored over a decent amount of time as I've seen tiny leaks like this spraying onto hot areas such as exhaust manifolds/turbos thus giving no evidence of any leakage.
If it's got those poxy spring clip type hose clips fitted, they can loose their compression effect because they cause an impression on the rubber hose without any grip uker: I always replace these clips with good old jubilee type clips as they retain their grip over a wider surface area :thumbright:
Maybe replacement of these clips might be an option/cure before spending too many £'s.
Certainly, by-passing the matrix and EGR will seal the cooling system to a given area to investigate and also eliminate these components from investigation :thumbleft:

 

On further inspection there is water trickling out between the head and the block just above and to the left of the thermostat.

So either headgasket or cracked head. Another call to Dave at billcar.

Ooo, not good news mate :cry and cylinder head removal for closer inspection ale:

 

Ahhhh bugger, sorry pal.. Not good news!
Are you doing it or has Dave got another customer?

 

Sorry too hear this mate we in same boat seen a lot of posts about this lately good luck hope it just ur gasket mate

 

Fingers crossed

 

It does appear to be the head gasket.

 

Simple fix mines due back tomorrow with. Brand new cylinder head

It isn't b;owing or showing any outward signs - temp is constant.

 

Mine has just started losing coolant all the time and overheating on drives that are over 10 minutes, it's just had a service too so I don't know wtf is going on

 

Welcome to the forum.

First check, did the garage put the spring loaded cap on the radiator instead of the expansion tank?

 

It's not uncommon for these to be put the wrong way round, that will cause overheating.
