Still keep having a bit of coolant leak its either very slow or a sudden leak of around a litre then stops again. Engine is 4.4 2015.

It's had the oil cooler gasket changed twice and then the oil cooler unit changed by MD. Decided today to have a look to see if I could see where a leak was coming from with my inspection camera.

Couldn't see any evidence of a leak on top of engine but did find what looked like a hole for a sensor or the like with what looked like marks showing something was fitted once.

the hole is to the left side of the oil filter at say 11 o'clock when looking at the engine from the front.

Any ideas looked at oil cooler pictures but can't see anything that resembles this.

Thanks

Looks like a possible pipe bracket that’s missing. Not 100% sure but looks like it.

My 2016 4.4 also had a very similiar coolant leak- never any sign of any leak under the car but it would lose a litre every 500-700 miles.

Took ages for Landrover to find it having changed various components including the Oil cooler - there was never any sign of any leak under the car. It was eventually traced to the EGR cooler. Current Fleet:-

How long has it been since the gaskets were changed etc. It could be that what you are seeing is airlocks working their way out of the system. Keep topping it up and see if it stabilises over a few weeks. There is nothing that can't be fixed with a hammer😜😜

I had the airlocks about a week after the last time it was in. This time low coolant warning came on weeks after it was in garage end of July. Always seems to be a few months after they sort it it starts again.

Hi , not the same symptoms bit my 4.4 2015 L405 has a very slow leak over the last 6.momths and was finally traced to the thermostat housing.

I saw that on an earlier post will investigate to see if any signs of leak.
