There is a huge coolant leaking in the back of the engine. By now is only water! I tried to look for the leak with a mirror and a flash light but I just can't see it! the leak drops into the (passenger side of) transmition. Even if the car is stop and I refilled the radiator, while filling it you can see the leak from the back. What can it be? Landrover Discovery II 2000 with 108,000 miles. I spend $3,000 five and a half years ago to replaced the head gaskets Help!!

if raining 100% normal. (rag top or hard top,?)
if the HVAC condensate drain PORT under car leaks pure water again 100 % normal. on AC or defrost modes, just like a beer can is wet .
same physics,(condensation)

if water is not water but is Green Coolant that is engine leaks.hoses, or RAD or over filled recover bottle. or
top of engine V gasket front ;rear leaks or coolant pump.
bad thermostat housing leaks too or wrong inside it gasket.
or heater core to right passenger floor well, core is bad.
my 08 jeep (rag) has no body drains for rag rain failures.
but the front cowl vents do. (so as not to food out HVAC air induction ports)
but not told what water means to you?
rain
condensate.
or engine coolant.

doors leaking rain water is huge topic, (seals)

sure all V6;s love to leak , at the "V" up top , loves to
and is 2 causes, bad gaskets or warped surfaces there.(heads)
can I assume the thermostat housing and pump do not leak now.
to find leaks and yes some are huge challenge
first make sure water (aka coolant AF 50%) is not found in the engine
oil or transmission A./T oil. (seen as green water or milky)

in your case it is to the ground and not to passenger toes (foot well)
leaks to the ground can be lots of places,
to find it use good a new RAD CAP not , 19 years old
get engine fully hot parked. best is idling parked until....
at hot idle 180 to 200F is par.
at this temp the rad PRESSURE IS 15 PSI (LOTS)
AND UNDER PRESSURE ALL LEAKS ARE EASY TO FIND
WARNING SOME LEAKS WILL SQUIRT 3 FT (1M)
AND FOOL ANYONE ONE.
if driving car then hood up wind-age effects move the water to false places. so do only parked tests even wash off old coolant so only fresh leaks are found.

MY GUESS IS (WILD) THE INTAKE MANIFOLD GASKET LEAKS
LOOK USING a FLASH LIGHT 360 DEGREES AROUND THE ENGINE
AVOID FAN, KEY OFF IF NEED BE. now asit leaks.
then make sure all core/freeze plugs on block and heads are no leaking. (under the tranny bell leaks, omg hard to find) but see only under the bell,. sure.
leaks are where you find them , just like finding GOLD
keep an open mind , take your time and it will be found.

Any where back there is a head gasket leak, unless it is at the very front of the engine(passenger side). Then it could be the timing chain cover. Use a mirror and bright light, You can find it.

The blue light is only supposed to indicate low engine temperature, reminding you to go easy on the engine until the light goes out.
The flashing is either for low coolant or for overheating, and it sounds like you are having a low coolant problem.
If after you add coolant the lights comes back, you have a coolant leak. The most common place for a leak is the coolant flange on the end of the cylinder head. If you take the engine cover off and look at the area where the transmission meets the engine, you should see either pink coolant puddling or pink crusty residue.
It's also possible to have other leaks from the radiator, heater core, water pump, etc. The nice thing is that with the pink coolant it will leave a trace of pink residue leading to the leak if you take a good look around with a flashlight.

to find coolant leak the coolant system needs to be under pressure.remove radiator cap ,located on top of radiator.caution engine must be cool.refill with 1/2 antifreeze ,1/2 water solution only..put radiator cap back on and let engine warm for 5 minutes.turn off engine and inspect where coolant is leaking. you can purchase a telescopic mirror at the parts store to look into places that are hard to see.to locate leak.warm engine should provide enough pressure to locate the problem

Leaking timing cover gasket or intake manifold gasket.

On the under side of the water pump there is a hole called a weep hole its there to let you know that the seal is leaking on the pump and will need to be replaced soon so you don't have a major failer on the highway and damage your engine

could be a hose leak or radiator leak, get fixed asap could overheat engine.

need to perform a coolant pressure test. fill the reservoir and after the engine cools down fill the radiator, next start the engine and wait till the coolant system builds pressure then turn off the engine and using a mirror and flash light look for a leak.check water pump, hoses,radiator tanks for cracks,intake gasket at the corners espesically at the back next to the trans.also pull the carpet back and check for coolant leaking from the heater core,and last remove the sparkplugs and check for leaking head gaskets.hope this helped.

When you replace the water pump you have to loosen the bolts that also go though the timing chain cover. This have to be removed and the gasket behind it replaced as well as two water pump gaskets. Check all your clamps (best to use new ones) first, but you may be having gasket problems between the pump, pump backing plate, timing chain cover and engine block.
