Need a little help trying to figure out what exactly this part is so that I can order it. I'm stationed overseas and the mechanics on base cant tell me what it is. Any help is greatly apprecaited.

That is the plastic manifold on the radiator hose.




About 50 dollars for the whole setup.

There are two types of setups and I can't tell which you have from your picture (but I think it is the newer style with a broken side out). What is shown above is the newer setup. There is an older one that has a hose exiting the main hoses rather than the plastic manifold. Either one will work since they both come with all of the hoses.

Since you are overseas, Amazon might be the best way to get one.

If you're replacing that and don't have a 180-degree thermostat (gray one), I would add that to bring down engine temps.

Thank you so much for the help I will get on Amazon and check for that part.

Replace the top hose that has the "Tee" fitting and the other 2 plastic return lines. That plastic material takes a beating from high coolant temps and the DexCool antifreeze, so if you have an issue with one, then the others are in about the same condition. Do some reading on here and some searches on the coolant system. You will find that there are several things that you can do to extend the life of your engine. The Disco2 can be a train wreck if you aren't proactive with preventative maintenance. block and cylinder head failure is a real threat, with a typical head-gasket failure being the reoccurring theme with this model due to a factory engine temperature gauge that does not indicate an overheating warning near soon enough, a corrosive red anti-freeze that uneducated owners continue to use, and a very poorly designed cooling system that becomes more faulty with every passing year to the point that the engine constantly operates 20-30 degrees warmer than it is capable of safely and reliably sustaining.
