Coolant and ATF fluid leak

[Ralph1Malph]

Hi Again,
Chasing down some leaks that I attribute all the work that's been done recently in and around the affected area.
Particularly, whilst chasing down a coolant leak I came across what I sure is an ATF leak, so two questions:

I reckon the coolant leak is coming from the small pipe shown - it feels a little soft and I think the hose clamp has either split the pipe or cut through, or coolant is being sprayed from the pipe below.
However I can't find it in any coolant diagram or parts list! It's a short U shaped pipe as indicated. ie, the end with the coolant showing, and the end below with rusty clamp are the same pipe!
Any clues as to a part number?

As for the ATF (I reckon that's what it is), I'm pretty sure it'll be coming from one of the ATF to cooler lines. Having never done one before (or is that yet?) are they easiest from the top or bottom?

I had a persistent oil leak wetness in this area and it was from the transmission cooler hose at top of radiator tight in with coolant bottle and the diff breather. The one you remove to push out transmission fluid if changing that way. It was just weeping and running down side of radiator a tiny amount. Coolant is very likely when filling the bottle it will spill down there.

Little U hoses are fuel cooler over by the starter motor. Little black hard plastic pipes into those rubber ones run under the radiator cowl.

Always a good method to use degreaser and wash everything and see after a few days with covers and lower plates off what comes back.

Removing the fan cowl and side covers gives great access to this area on 2.7 and very easy to strip and access hoses and thermostat. Pop all the hoses off from the underside cowl brackets before trying to lift it out and don’t forget small bolt at side of plastic air delivery pipe to turbo that connects to the cowl.

Hi, Yes.
What I posted was after a good degrease and about 5-10min running to pressurise the cooling system.
I was more surprised how quickly the ATF is leaking.
Agreed easy to get to mostly, but I'm stuck as to the p/n for the coolant hose in question. I'm sure its a short U shape, I traced it with my hand, but could be wrong :unsure:
Either way, it's sunday arvo, I've little motivation left this weekend lol.

Update:
Pulled the fan and shroud for better access.

The ATF was leaking from where the ATF hose enters the cooler, the hose was able to be rotated by fingers! But. I couldn't tighten it because of a dodgy hose clamp! Replaced the clamp and I reckon its good!

The coolant is a bit more annoying. The hose below the ATF seems a bit 'soggy' and the clamps are rusty so I'll replace the whole bit. It is a 'U-ish' rubber pipe which joins to a plastic coolant line as seen in the bottom of the pics where the weeping join is.

Surprisingly, I hadn't noticed the leaking coolant around the temp sender, so new one of those inbound as well.

Frustratingly, when I removed the fan, the fan connector wasn't connected, which may explain some erratic temps and A/C cycles I've been getting since the A/C compressor was replaced.

Ralph, what coolant is that? Looks like Castrol.. Also is it the original fill or after a change

Hi
The car has had numerous flushes for various reasons, oil cooler, radiator changes etc. Currently it's got Nulon in it.

The offending hose!
All sorted now.

Ralph,do you have the part number?

[PerthDisco]

Has anyone priced up a new set of coolant hoses recently?

That looks like the hose that goes from the bottom of the radiator to the supplementary single row radiator that sits in front of the condenser and feeds the fuel cooler.

That be the one!

The reason I commented is when we bought the Antichrist it came with a built in coolant leak. The Indi suspected that hose, so replaced it at great expense (it wasn't the only leak as it turned out). The leak actually turned out to be a pinhole in the cooler just past the bit the hose connects to, so I bypassed it. I have a new one waiting for installation at the next coolant flush.

This went back to the mechanics several times for this leak, and when they obtained the hose they commented they'd never seen one of these coolers before. I assumed it was an oddity of the vehicle (seeing as it had all the UK fruit + DPF), so I was surprised to hear it was on some Aus spec vehicles also.
