    Yes, however being an experienced person myself in auto mechanics I would have liked to know the location of the water pump. Most helpful suggestion was the hose location behind manifold. This is the problem. There is no way I'm tearing into that assembly as 3 days time and cursing vs 5 hours at jag servicing at $1200 seems to be the better option.

    Thank you.

The leak is most likely the pump itself or pump gasket. I also see issues with the thermostat housings which can drip down from the top and look like a pump leaking. To find the problem a pressure tester needs to be installed to the coolant tank.

I usually find the leak with the tester. The best method is to clean the area very well then put the tester on it looking for the leak. Also on your vehicle you may have a leak from one of the hoses under the intake which will run down the front of the engine.

The cost for the thermostat, water pump and hose replacement will vary. To give you an idea to replace the radiator, bypass hose, thermostat, and water pump it about 5-6 hours labor. The heater hoses will be additional as they run under the intake. The parts are about $475.00 but I would need your VIN to be sure. I also see issues with the thermostat housing. Sometimes if the engine was running hot the brass inserts can strip inside the plastic and the housing would need to be replaced.

Good Luck!!

Leaking in front of back passenger tire

Look for a dislodged Air conditioning drain hose. This hose sometimes gets kicked off by a passengers foot. The hose is a jamb fit. It is typically black, about 1/2 in diameter.

Power steering fluid leaking

It's either a power steering return line or a pressure line.

You need to have it in the air to diagnose definitively but the rule of thumb is that if it's leaking and the puddle is in front of the passenger tire then it's a return line or cooler, if it's behind the tire then it's the other side of the return line, or a pressure line.

Either way get it changed before you break the power steering pump which isn't cheap. Also, stop leak ruins the pump so don't put any of that in there, just get it fixed soon.

Coolent leaking

i doubt very much wether the block is cracked it is more likely to either be a heater hose may be leaking or a welsh plugs ( little round dish shaped plug ) in the side of the block i would first check all the heater hoses and the look on the side of the motor for a possible welsh plug leak i'd say its hoses tho
