I did mine a couple of years ago. Another time, I replaced every coolant hose on the entire engine, the oil feed seals to the turbo ( you mamaged to get viton, which is superior), and all the plastic coolant pipes and thermostat housing complete. This is because I don't want to be going in there again anytime soon. A big call calling that job suitable for competent DIYers I think.
Have just changed mine, wish I had also got the pipe that runs from the above the radiator to the front of donut as that snapped at the t junction, that stopped me in my tracks, but have fitted a new one. Luckily only a 5 day delivery. Did not realise you were so local to me.
Question: if the root cause of an oil leak is due to gasket, would it be possible to just replace the seals? I mean other than bad seals are there known problems of internal strutural integrity failing on these oil coolers?
Thanks for the feedback, appreciate it. It’s a good question. The oil cooler unit can either suffer gasket failure or the aluminium heat exchanger/mount can warp/crack. It can be a bit tricky to diagnose the exact failure mode and it takes time - I usually have a fairly long list of car jobs each week so I’m always trying to spend my time effectively. If it was your own car and you aren’t reliant on it as a daily and you are happy to tinker it’s worth having a go at replacing both gaskets along with the oil feed o-rings and water feed o ring.
Oil - no, but you do need to loosen off the oil filter and let it drain. Be prepared to catch oil. Coolant - the coolant channels are fairly complex and draining the whole system is a bit of a faf I’ve found it best to have a couple of large drip trays underneath to catch the coolant. You are pretty much disturbing the top of the system so you don’t loose that much.
@jamesg25 I have oil in my coolant and the local garage conducted a sniff test and concluded the head gasket had gone, they are not a Land Rover specialist and I’m wondering if the cooler had gone or egr problems would show similar symptoms to head gasket failure to an untrained eye?

At that time, not another time!
Nissens are available from Advanced Factors at reasonable price 😊

Hi i have same problem thank you for perfect info

Great content! Keep it up! One question, why does the whole oil cooler needs to be replaced? Isn't sufficient just replacing the two gaskets?

I got oil pressure light flashing with cold engine after changing the cooler. Did not have it before.
Is it a coincidence or a bad part i dont know
Hi. Great content. Do you need to drop the oil and coolant levels to do this job? Thanks :)

Thanks for the reply - appreciated.
