Coolant leaking from gasket in back of engine

Gents, I have a 2010 XK. A few days ago I was in traffic, then had a chance to open 'er up, Outside temp was around 100 (I live in Houston) , then went from a stand still to 60 then to over 100 in a matter of seconds. All of a sudden, a warm rush of air from AC and low coolant light came on. Eventually, engine overheating message came on. I pulled over to let car cool and also turned on the heater full blast as soon as the message came up about overheating. Finally got the cart home and did some preliminary reading. I bought an OEM thermostat and replaced. Loaded the car up with a gallon of antifreeze (orange) and almost immediately fluid was spraying from back of engine. Not the hose that runs there, but from what looked like the gasket between the V (she's a V8).
This area did not appear to be connected to the intake manifold, but it was definitely anti freeze spraying from the sandwiched metal just under the back hose. Any ideas are welcome. Thanks!

If a failed hose is not the problem, it sounds like you are going to have to remove the intake manifold and look for a failed gasket.

I was going to ask the same question. Once the low coolant light comes on with any 2010 XK/XKR + it's time to shut the car off immediately and look for a tow to the dealership. Too many instances that driving even another few feet can and will cause catastrophic damage. Same thing happened to my neighbor and after topping his car up, drove it home (a few miles) and ended up replacing the head gaskets. The low coolant light is useless and it doesn't inform the driver that it's not necessarily just the reservoir that's empty but most of the coolant is lost in the car...period! Very bad design. Read other threads on the overheating issues with 2010 XKs and newer. Many water pumps but other issues as well. Good luck and let us know how you made out.

It was a blown hose. I had them go ahead and replace the water pump since they were in there, and I did the thermostat. Our outside temps hit triple digits this time of year and wanted to be proactive to avoid any potential overheating in the near future. No damage luckily. On a different note, I was having some occasional random TPS error messages that have since gone away. Go figure LOL. Thanks everyone!

Please identify the blown hose, perhaps you could list the part number from the invoice? I'm also interested in doing some proactive service on the cooling system and would like to learn which hoses are most likely to fail.

I believe I'm currently having this same issue. Once i got my vehicle towed home I started looking for the leak. I can tell its from the rear of engine leaking onto the transmission, but can't see exactly where. It would be helpful if you could provide a part # of what was replaced so that I can see a diagram of what was busted. This might be the same thing that's happening right now with my vehicle since its exactly same symptoms Dip in AC cooling followed by "coolant low" message. Any help would be appreciated! thanks!

Hi Tommy,
In the exploded parts diagram, I noticed you marked the top two hoses (#9 and #10) with "x". Does that mean you decided not to replace them? If so, is that because those hoses are easy to inspect, so hopefully you'll have warning before they fail?
Thanks!
