Minute invisible leak

[rangerover]

My 2001 model P38 is leaking water at very slow pace that after 1000km or so i need to refill the expansion bottle.

Inspect the car nicely and just found some coolant green color marks behind the radiator fan, little below on the engine metal.

Is there is any gasket there that need change or if any other is leaking from top and seeping thru that area. Apart from that place i havent seen any green color coolant stain anywhere. Last year i spend about 2000 dhs in making all leaks on engine oil and gear oil and now this is appearing, dont knwo what to say. Land Rover loves to leak, i guess, no matter how much i want to keep my parking clean. Any help is highly appreciated. Thanks guys.

It seems like your water pump has started to leak. Its completely age issue, so get that checked with mechanic if i am right or not.

Its not expensive fix, couple of hundred dhs thats it. Better fix it than leaving as you never know when this dying water pump fails completely.

My friend, leaks are very risky to ignore. Get it check and get it fix as in P38 gauge continue to show normal untill 119 degree, where as its normal is 100 degree. And at 120 it shows immediately to full extreme right with redlight showing OVERHEAT. So watch carefully.

Before gauge happen to move its a$$ from center, you will notice AC being cutt off (in case it overheat) and so that you can be sure that engine is under stress and pull over and check.

If i am not wrong after every 40k agency guys changes the water pump even if there is no complaint in a way to protect engine if it break down during the period.
