Will EGR blocking plate fix EGR Cooler leak?

[Gazzafish]

My 2005 TDV6 is losing a very small amount of coolant and I can see no traces of it anywhere. I am expecting a leaking EGR Cooler.

From what I understand, The EGR cooler is a heat exchanger and has 2 separate areas. One area is where the exhaust gas flows in one end, along the cooler and out the other end into the EGR valve. Also inside the cooler, is a complete separate 'cooling' chamber which has coolant flowing through it which is used to cool these exhaust gases before they enter the EGR valve.

So, in theory, If I put an EGR blanking plate on both ends of the exhaust flow. I.e. From exhaust into cooler and then a second plate between cooler and EGR valve, If the EGR cooler is leaking coolant, it will simply fill up the cooler chamber completely and I wouldn't lose any more coolant?

or have I got this totally wrong :D (highly likely)

Hi Gazzafish,
Check the "plastic" cooling water outlet housing on top of the engine at the front where the top hose connects. The water leaks into the centre of the V and evaporates with the heat. You usually don't find it until the leak is so bad that it fills the V about 2 litres of coolant and you get evidence of a leak from dripping around the front of the gearbox.
The housing is relatively cheap and easy to fit.
The two clips on the EGR pipes are a bit of a bugger so buy two new ones when you buy the outlet housing. Bit of a bugger this I have a spare one in my shed, you are in Melbourne.
I have had three crack and start to leak. Small coolant loss over a long period of time.
Never had a leaking EGR cooler, my advice stay well away from them, a living nightmare especially if you decide to replace them. That's my opinion, I have replaced one for a different reason than a coolant leak.,

I would not have thought blanking the EGRs would stop the coolant leak as it would still be going into the exhaust and then out the exhaust pipe.
