Default coolant leak need help finding.

Water is running down the top of bell housing driver side not coming from the hoses on top must be from a hidden hose further down. I have been all over with a flash light. It runs on the ground just to the inside of catalatic converter not dripping on converter. Will be very thankful for any help.

OK, LHD.

Heater tap.

Those 2 heater hoses on the Left (drivers) side at the rear of the engine bay, easy to get to HAHAHA.

Thats all I can visualise on that side of the V12.

LHD no idea.

On our RHD the washer bottle, cross over balance pipe, skin from knuckles, more skin, really no easy way. Just work your way down to the clamps, and they can be a pain if installed upside down, and then just carefully remove the 2 hoses.

Refitting will test your sense of humour big time.

Disconnect the battery, you have a +ve battery post stud just there, and a slipped metal spanner will toast the alternator in a flash, and scare the hell out you.

there are 3.

One FROM the rear of the RH cylinder head that goes TO the heater tap.

One goes FROM the tap TO the lower spigot of the heater core.

One goes FROM the upper heater core spigot TO the stainless pipe travelling down the LH chassis rail to the radiator return point.

Water/coolant down the bellhousing is generally the heater tap. However the amount of work involved, I always do ALL those hoses with the tap, and of course new clamps.

I replaced a heater hose passenger side that was leaking a couple months ago it was on top very easy to change. One leaking now is driver side I can't see the hose so I don't know how I will change it.

I would suggest a good dose of bravery, some JD, plenty of time, and simply just get in there and sort it.

It will be a HUGE learning curve into V12 ownership, and sooooooo satisfying when done.

It is one of the tasks that reinforces what you hear from me and others on here. "Do it once, do it PROPERLY, revisit in 15 more years".

The o/rings on the oil filter housing is another "stressing task", and fun to do do, NOT.

From the top. There is no way you will get to them from the bottom.

It is really not that bad, it just looks like it, but sensible removal of what is in the way (and LHD I have no idea), and just take your time. Getting the 2 hoses off the heater spigots is stressful, and I usually remove the clamp, and VERY CAREFULLY slice them with a sharp blade.

Don't have to remove the washer bottle, just the stuff above the hoses and ....(trying to remember) ...maybe the cowl drainage pipe and a vacuum line on the drivers side.
