Hi..our LR3 4.4 V8 has a Coolant leak..that is elusive.
Shoppe did a Pressure Test and no Leaks..so put new Coolant and said they can not find anything wrong with car when driving nor a leak.
We pick it up..drive 17 miles(more than I expect they did) and in two minutes parked floor has a 16" circle of coolant and the whole outside
front of car smells like Coolant..and though gauge on Dash is spot on Engine seems to feel quite hot.
This video shows a couple of plastic lines under the "Manifold" of a Range Rover Sport (Same as LR4 but 5.0) that seem to be a culprit in many cases..
Is the 4.4 V8 laided out with similar lines ?
Here is the video on YouTube with guy pointing the lines out...the one in front is a Y shaped thing (Cross Flow Pipe ?) and another straight one in back. THANK YOU AS ALWAYS

two very different motors

So no ..? those two coolant lines this man is pointing out are not in the V8 4.4 ?
Anyway..
I have a new development on the "Elusive" Coolant Leak..it was not elusive at all..it was just
negligence on the part of the Shoppe I took it to who held the Car for from Mon-Sat. (Our only car.)
After we picked LR3 up got home having driven 16-17 miles..the whole area smelled like Coolant..
Within 2 minutes underneath Car was a 16" Circle of Coolant plus some more in spots around it.
Later.. neighbor calls and and says, let me look at the Car.
He opens Bonnet and presses gas and its obvious something not sounding right.
He says to my wife lets go for a ride..he takes her directly to his mechanic who is still at his Shoppe at 6:30 on a Sunday ready to go home.
Our neighbor is pressing gas ..mechanic is moving hoses and wife who is short says wait I see coolant splashing out underneath Engine Cover.
They took Engine Cover off and one of the Hoses was completely broken !! ???
The Shoppe in one week did not even bother examining the Hoses..we could have burnt our Engine.
So obvious it was diagnosed in 2 minutes..and that Car was over there for a week while we are Ubering back and forth..what Bums.
The neighbors mechanic rigged up a temporary fix (a tube and two clamps joining the two hose ends) so we can get around
and ordered the Hoses that all looked dry and so ready to go.
A nightmare..now we are in peace

I replaced it with a brass one.
