Have recently replaced heater and radiator hoses..Now two months later have found several puddles of nice fresh radiator fluid..
Have searched and searched and all I can find is this from the back drivers side of the top of the sump..
Is there something there that may be causing this and what to be done to fix it..
Thanks in advance..

Just found my leak and i think yours could be the same. Do you seem to have a lot of condensation on the inside of the windscreen, Odd smell inside? Unexplaned coolant loss? My heater has been leaking and i finally put 2 and 2 togther, pulled of the trim under the glovebox and found spots of coolant, main loss goes out the condensation drain on the firewall. Pulled one of the hoses off and bent the other hose around to bypass the heater. Tomorrows job will to be to pull it out.

Just had another look at your photos, that looks like under the water pump, can just see the end of the timing belt tensioner.

Yeah it is drivers side near the timing belt tensioner..
Had a new pump put in when belts were done 40k ago..maybe the seal is leaking..??
does not leak all the time though..and seems to be not losing a lot,only a cup full when parked when hot,..
Everytime I go to look it does not leak..go out half hour later and there is a puddle..driving me crazy

If you can't work it out, I'd get it pressure tested and that way would force the leak and trace it that way. Had subaru with a similar issue, appeared to be leaking at the side and rear. Too slow a leak to trace, but left telltale signs. had it presurised when cold to force the leak, was all the way up the front and traced to failed waterpump shaft seal.

If it's a cup each time that's a lot if driven once a day, 7 days = 1.75L loss

I had an identical coolant leak on my daughter's TH Advance. I traced the leak back to the gasket between the water pump and the backing plate. Not a 5 minute job even to find the leak, let alone fix it. This was at 108000 Kms. The service book showed a new timing belt and water pump fitted at 90000 Kms. After much spanner work I discovered the water pump's backing plate had not been cleaned of all the old gasket material before the new pump was bolted up. I'm surprised it hung on for 18000 Kms before the leak got really bad.
