Giving an Exact diagnosis is impossible at this point, but I try to promote what youre saying!!!

Heres a pic.....

Where the plastic clip is that's holding the black plastic tubing.. Look directly right of that, its the nut the bolt threads into.

Directly below that area, the metal cylinder you see is the Fuel Cooler...
The end seals (O'rings) often leak.... I'd bet thats your coolant leak...

It hides under the inlet manifold as seen in this pic below:

Did they replace the coolent on the service,maybe systm was not bled correctly
Was the service done by LR specialists,if not dont go back,if so we all need to know.

Sorry for the delay in responding but I lost access to the PC for a while, thanks for your replies.

The coolant was the only thing they didn't change oh the irony

They also put on a new fuel block. As I am new to this stuff I am not sure if this is located near the fuel cooler, which was mentioned by Tombie.

Yes they are LR specialists which is why I travel a bit to get to them. They come highly recommended by many on this forum and I am not here to bag them. As often said, anyone can have a bad day, it will be how they respond that counts. Timing is annoying as I really want the car for the weekend.

So far the consensus is no connection between bolt and coolant which doesn't surprise me. Could be just a coincidence. The only other clue I have is that the cap to the coolant was loose so perhaps when they checked it to see if it needed changing they didn't put it back on properly but in that case I would expect a lot more splashing around the engine bay at that level. Also, as I wasn't home when this happened and the neighbour came over to check it out with my wife he may have fiddled with it.

The Fuel Reg is just behind the back of the cooler, and the end of the cooler is susceptible to cracking back there...

Its possible, that the replacement triggered an aged cooler hose / fitting to crack or fail.

and then dont bother putting the cover back on again, as it all it does is hide things.

Been back to mechanics.

Yes, as we all thought/knew, that bolt had nothing to do with the problem so minus one point for RACQ (but they get it back for towing my car to Redcliffe from Ferny Grove). $20 for a new nut and bracket.

The fine folks at the mechanics spent some serious energy trying to find the problem as quickly as possible even though even Blind Freddy could see that nothing they did at the service could cause this problem. So full points to them for that. Pressure test held steady at 20lbs, no leaks were found anywhere. Problem has not reoccurred. Conclusion is that the only thing that they cannot test is the coolant reservoir cap so it probably had a malfunctioning valve, maybe triggered when they checked the coolant during the service. This is apparently consistent with the coolant escaping via the overflow nozzle. Replaced cap for $50 and will now keep an eye on it.

If I gave the impression that I had lost confidence in the mechanic then I apologise to them and others, as I had not. I did not trust my own instincts enough to ignore the RACQ advice when I wrote the post. I was confident that even if they had caused the problem they would have fixed it and they responded better than I could have expected.

If it blew the colant out the cap from over-pressure my bet is on the head gasket... or perhaps a failed radiator cap. Usually you will have noticed some slow coolant loss between services though.

Have a look where the overflow is directed, mine left coolant stains on the side of the acoustic cover.

Those LR specialists you went to are great,i go to them as well

Its worth the drive
