I have a coolant leak on my 2003 Disco. It appears to be coming from somewhere behind the A/C compressor. There is a hose there but I am unable to tell for sure if that is where it is leaking. It only leaks when the engine is running.

Thanks in advance for any advise.

 

Sounds like it is the throttle body heater gasket leaking, very common leak on DII's.
Go to the write up section on the top of the DII page and read through it.
It is a pretty easy DIY, $25.

 

Thanks Spike! I read about that earlier and checked right away but it is leaking farther to the left behind the compressor.

 

You are going to have to pinpoint the leak, there are 2 coolant hoses that run to the t-body heater and they can become brittle and crack.
Take a flash light and remove a few things if you need to so you can see better.
Once you find it let us know.

 

That was my next step was just wanting someone to reassure me it was the best thing to do. Thanks Spike!

 

You are on the right track.
Keep us posted.

 

I unbolted the A/C compressor and moved it to the side. As soon as I did I saw the problem. There was a hole in the Expansion Tank To Throttle Hose. Ordered a new one and it should be here today.

if the hoses have never been replaced now would be a good time to do them all...

 

Do you know how to bleed the coolant system after replacing that hose?
