Disco 2 2003. I need some help identifying this hose. I believe it is the source of my coolant leak but I can’t seem to find it in any diagram. Thank you.

 

I was able to identify the hose in the post above. The coolant leak is actually coming from the groove in the middle of the circle below. It is a slow constant flow while the engine is running. The flow stops when the engine stops. Can someone tell me how I can fix this and what I need to buy? Thank you.

 

The hose circled in the first picture is one of the power steering lines. The coolant leak is most likely leak further up the block. Likely causes are water pump, front cover, coolant outlet pipe, etc. You can add UV due to the system to help find the source but if it streaming out as you say it should be obvious.

 

Can you post photos from some better angles of the area where you think the leak is? That just looks like part of the cylinder head to me, and there wouldn't be a leak there unless it was cracked. There are a couple of coolant connections in that area though.

 

The amount of RTV used on that oil pan gasket makes me sad for you whenever you have to scrape it off to replace someday.

...just noticed the same with the water pump too. Yikes.

 

Here is a close up picture of the location of the leak.

 

I’m in the military stationed overseas with no easy access to professionals or parts. I don’t have a lot of auto mechanic experience so a lot of the repair jobs are not pretty. All of these repairs are done in a parking lot with a jack and some stands.

 

Well…if it’s actually coming from that gasket, that’s the head gasket. There’s a water jacket there that definitely could leak, but there are also a few other leak points around that area that could make it appear it’s coming from the head gasket.

 

It is definitely coming from that spot. I can see the fluid bubbling out of it. What does that mean? And how can I fix it? I have some high temp JB Weld that I was thinking of throwing on there. In the attached video you can see the bubbling.

 

Hm.

I had a similar situation where the intake bolts weren't tight and was allowing coolant to seep almost in that exact spot.

It's a stretch, but it's easier than head gaskets. Just check the torque on the lower intake bolts.

You can also check torque on the head bolts. They will measure out to around 120 ftlb after doing the torque sequence and angle.
