So I just drove my '00 Disco 2 all the way from TX to Seattle and it ran great. Right before that I had replace head gasket, water pump, resurfaced pistons. The whole 9 yards.
Month later I noticed that coolant was dripping BUT only when I start running the car. It drips off pan gasket area but it looks like its just follows the shape of the engine from somewhere around oil filter. The big hose looks dry. I can't see anything from the top but sob just keeps on dripping.
Any idea where else to look? I really do not want to take to the shop and get 4 page list of whats wrong with it.
Also, anyone knows good shop around Tacoma/UP area for Land Rovers?
Thank you.

 

had the same problem area probably the water pump weeping hole
take off your belt and feel for play on the water pump shaft

 

I'll give it a try this weekend. Bummer, this was brand new water pump. I wonder if o-ring failed.

 

It could also be the timing cover leaking

 

Wouldn't it leak all the time? this one only does it when I warming up.

 

When warming up, the system is under pressure. Almost all coolant leaks, unless they are a broken hose or fitting, will only occur under pressure and when running.

 

Check the black plastic triple conector below thermostat. The smaller nipple (which goes to heater core tube) will crack and weep, normally, only under pressure.

You can see the water pump weep hole without removing anything, check that first. Could be the end of the heads, could be the intake manifold, could be the front cover,etc. Coolant doesn't evaporate. Start at the bottom and look for moisture all the way up. If you want you can put some UV dye in it and look for the traces. Also helps sometimes to borrow the rpessure tester from advance and put pressure on it, a lot of times you can hear it or see it with that because the engine is not running and there is no noise and the fan is not blowing it all over the place.
