Red pool

In mornings there is a small pool of red oily liquid on floor below gearbox. It must be ATF.
Thing is I can't see where it is coming from. I can't see it dripping down but the pool is there in morning.i park in same place at work but there is no oil drip there...only in my garage.
Any suggestions thank you

It's not ATF, it must be coolant-I have red antifreeze in it.
Saw drip from back of engine. Tasted it and it was nasty, not like oil.
I checked ATF level n that came gushing out so that seemed overfull, lost about 1 pint. Was diff shade of red.
Where cad water drip from back of engine?
Thank you.

Valley gasket has been known to leak!

I hope that you did it correctly, not just unscrewed the filler plug.

Didn't know valley gasket was a water seal. I will try and see where water is coming from. It's hard to see back of engine.

Checked it on flat with engine hot and running and after cycling through gears - is that OK?

you could be right and I could be thinking oil...

Core plug maybe!?

Yes, accept my apologies for doubting you. It was only because you said that you lost about a pint. It's quite difficult to over-fill the boxes without a dipstick.

As for your leak, and I'm a diesel driver so no V8 expert, but I seem to remember talk of a water leak on the front of the engine but the coolant dribbling off the back of the block? Maybe one of our petrol lads could comment?

Should be done with engine and box cold engine idling and after shifting through the gears. Hot it will always appear over full.
You are now short of a pint of oil

Oh dear...
Will have to do same again but cold.

Gave her a bottle of K-Seal on Monday.
Since then no drips and no coolant loss.
So far very impressed.

You won't be if it blocks the RAD and overheats

V8 cooling system is already pushed without clogging up further. If your rad wasn't ready for replacement it will be now.

The problem is that you still dont really know where the problem lies and remember with the v8 if the cooling system lets go in a catastrophic failure it pumps all the coolant out in seconds and does not register on the temp gauge the first you will know is rough running as it cooks best to find the fault and replace all components compromised and tpo be fair with k seal in thats the rad the thermostat the pump and could be the heater matrix which is none too big to start with anyway good luck but I know what I would do and indeed have just done after two hgf in a month

Problem was losing water.
Now it is not losing water.
If it's not losing water surely it is less likely to overheat?
Temp is very stable

Maybe for now. I'm not saying K seal wont stop a leak....it can do that pretty well but in time it can clog things up & you may well have overheating problems again. If it were me i'd flush the system & add new coolant.
These 'chuck it in the cooling system & leave' products are no good IMO. Something like Iron Tite is a better option where it is run into the system in a controlled way & then flushed.

Checked ATF level when box was cold. Still poured out but only a little with fill plug removed.
Must have been previously overfilled some how.
