Hi All
2008 Disco 3 2.7 Tdv6
I think I have a coolant leak from the fuel cooler module that is under the left hand side above the rear bush on the front suspension wishbone. My symptoms are that when I drive very steadily it does not lose any coolant but when i apply power the system pressurises and i lose fluid and the it seem to be dripping from the front wishbone bush. on inspection the fluid seem to be all around the diesel pipes that go into the cooler. I clean it off and run the car and it will run and not show any signs of a leak untill i take it for a run. I have spent hours bleeding the system ( with the front jacked up about a foot )and running the car and it will not leak. when i come back from a run the cooler is wet so there must be a leak in it . I have also removed the second battery and the box to check if its leaking from any other part of the system and running down and can not find any evidence of leaks. Im wondering if the cooler is prone to leaking as on inspection it looks like a solid aluminium affair and there is no evidence of the pipes going into it leaking.
Has anyone had anything similar? and can anyone suguest another place it could leak from. it dosent seem to be coming from the EGR valve. Thank you for any comments

Start with the basics, is it confirmed as water and not fuel?
If it is believed to be water is it slightly sweet to taste/smell in othr words does it have anti freeze in it
This will at least prove it is coolant rather than fuel.
Have you triedclamping and then removing the coolant pipes for a better inspection of the unit/ends of the pipes. MY17 D5 1st Edition Namib Orange
MY15 D4 HSE Kaikoura Stone
MY12 D4 HSE Nara Bronze Sold and gone
MY11 D4 HSE Stornaway Grey Sold and gone
D3 S spec Silver Sold and gone

If the front suspension is still genuine then the lower bushes are Hydro and when worn can leak fluid. I am assuming that you do not lose coolant.

it is red coolant and i will not taste it as anti freeze is one of the most highly toxic substance and can kill you.and yes i have had the cooler off and it is definitely coolant. and i lose coolant and its the only place i can find that is wet, the joints are not wet but i cannot see any damage to the unit there must be a pinhole in it somewhere that spays it out under pressure in was wondering if it was a known fault ,
thank u for the reply
