Help me identify the part - XK 4.2 NA - 2007
 

Hello forum,

Last week I bought an XK 4.2 from 2007 and today I got it on the lift at my friends place and we noticed that I have a small oil leak coming from this part:

I guess this is an engine oil cooler but it seems that someone bypassed it. (I guess it was leaking coolant into oil system)

Can someone please help me identify the part number so I can try to order a replacement unit.

Thank you!

:eek:

Sorry, couldn’t help it.
I ordered a spare a few years ago and this was the part number listed in the eBay ad:

6W83-6A642-AA

Maybe here: https://parts.jaguarlandroverclassic.../brand/jaguar/
or
https://parts.jaguarlandroverclassic.../brand/jaguar/

Here’s the part listed on our forum sponsor’s web site:

Not necessarily leaking. The oil filter is awkward to remove without the correct fluted key and a PO could have done this to make it more accessible. Given the cost of a replacement cooler and that it's showing as out of stock at Jaguar, I'd reconnect it and see what happens. Just run it up to temperature and not embark on a cross country tour, of course. :icon_lol:

Thanks a lot for the answers provided.

When I search for 6W83-6A642-AA it gives me a Ford part which is priced at around 80 euro. The one from Barratt is priced at 485 euro. :icon_eek:
They both look the same on the pictures tho. Will give it a shot with the Ford part since it a lot cheaper.

I managed to find a mention of this in the service record from last year. Car was at the official Jaguar Land Rover dealership here in UAE and they made this bypass since the replacement part was not available at that time. Dodgy repair by official service center if you ask me.

In order to change this part out, I need to drain both oil and coolant, right?

I agree the images look the same so that would be my approach too. Ford parts specialists are showing it as discontinued but that same number 6W83-6A642-AA led to this ebay listing:

Worth investigating.

An oil change is a given as you will be disconnecting the filter. Coolant loss can probably be limited by temporarily blanking the hoses but I'd take the opportunity to do a flush and refill.

Earlier this year car had an oil leak. I thought it was a failed gasket within the oil filter, or a coolant hose. But it turned out to be the oil cooler housing, once ordered part took approx. 8-10 days to arrive. Billet not plastic, there are two types. No leaks since (knock on wood)
