Hi, All I have a 1986 Jag v12 I noticed water leaking I thought it was the water pump, it was coming from that area looking at the pump not wet that I can see .But it was wet by the I guess the cooling fan bracket/ bearing assembly that bolted to the cooling fan?? right next to the water pump This is my first Jag v12 interesting car.. I guess my question is it the pump or the cooling fan bearing assembly I thought maybe someone has run into this problem and let me know... Thanks for your time

 

OK,

You have a steel pipe running around the front of the engine, and it has the coolant filler spout on it. There are 3 hoses on this pipe.

2 smaller hose at each end, where they attach to the thermostat housings, and 1 larger hose that attaches to the TOP of the water pump. You will need to look very closely for these hoses as they are somewhat hidden.

These hose will be your issue in my iopinion.

ALSO, that steel pipe rots out, lack of proper coolant many years ago, and I would be giving it very close inspection, particularly on the underside.

 

Also check the inflow point from the rad to the water pump. This is where the large J-shaped bottom rad hose joins the pump inlet under the pump, very hard to get at, like the cross pipe hoses Grant described. If you have never changed the hoses, all 14 or whatever of them, plan a couple of days and get stuck in. The best way to find small leaks is to run your dry finger around each hose/pipe join carefully and look for wetness (just in case you were not sure).
