Transmission oil cooler, water pump, and head gasket leak
Recently i started noticing a leak from the driver side of my disco 2 near the radiator. I took it in to an indy shop to find out what was leaking and get an idea of what was going on. The shop told me it was the transmission oil cooler. However, they also said that my water pump weep hole had a major leak and that the head gasket had a light leak. The weird thing to me is that I have not noticed any coolant loss and it has been driving fine. I had them put in a new water pump and drove it home. I am looking for advice as to how to move forward and find out for sure if there is anything going on with the head gasket. Is there an easy way for me to test to make sure they are not giving me the run around? I feel pretty comfortable working on the car and plan to take care of the transmission oil cooler leak and feel like i can probably do the head gasket job after reading up some. Thanks for the help.

As far as I know the water pump weep hole is there to indicate the water pump gasket has failed and needs replacing. It's a good design that works.
There is a good chance that that is the end of your problems.
I would watch things with an eagle eye, to see if you have any more coolant loss, or signs of HG issue.
I say this having only ever read about the water pump weep hole. You'll get a more authoritative reply shortly, I'm sure.

cappedup is correct, the weep hole is there to let you know the seal has failed and replacement is needed.
Do not rely on your factory temp gauge to tell you if it is ever overheating, they are useless.
Most members will recommend either ultra gauge or something that will give you an accurate temp reading. I use phone app called DashCommand that connects to obd2 wifi that plugs into diagnostic port.
A leak test is the only way to tell if anything else is in fact leaking from the coolant system.
The transmission cooler may only be a bad line and easily replaced.

I have used there kit several times, never had a problem. check see if it comes with the upper intake gasket.
look to kingsborne for wires order their 8mm wire, good wire , crazy cheap prices.
180 stat is great make sure its a LR thermostat, to many problems with the copies.
if you don't have one you might want to order a fan blade wrench.
UN-TORQUE YOUR HEADS, don't just start pulling head bolts. remove them from the outside in, or you will end up with problems trying to get the rear head bolts out.jmho

I would buy your head gasket set from Lucky8. Call them and tell them what you are doing, they will set you up with everything needed and at a better price than AB.
Good luck.

Drain Plugs
locating the coolant drain plugs on the block
and that the head gasket had a light leak
The shop told me it was the transmission oil cooler.

Thanks I will try to find those drain plugs today. If I can't find or remove them is there any other ways to get the extra coolant out?
I am also having some difficulty with the SAI and remove the large Union nuts that are at the bottom of the head connection. Any tips?
I will be replacing the transmission oil cooler as well during this job to address that leak.
