Just a FYI. 2013 XF 3.0 S/C
I replaced my front crossover pipes and waterpump and do not like reusing any plastic drain/vent screw/plug.

The first issue I encountered was the radiator has different revisions/suppliers and if you order C2C1467 you will receive a LONG drain plug with a O-ring type seal. Some cars have a short drain plug with a washer type seal. That part number is JLM20622. It cost like $18 at Jaguar and it terribly overpriced. You can also get it on the Ford parts catalog f5rz8115a.

The second issue is the bleed screw on the metal pipe on the passenger side of the engine bay. Jaguar is not like BMW in that they want to sell you everything in a unit. If you want that bleed screw buy the entire coolant pipe. The good news is the bleed screw is rather standard and you can get it from BMW 11537793373 or Dorman 902-404. These replacement screws are a tad bit longer then the factory screw but I don't see it causing an issue.

Some people also replace the plastic bleed screw with a M10x1.0 brass bleeder screw but I would recommend against that. You might end up having issues with corrosion from dissimilar metals and never be able to remove it again.

 

Fair. I went with a brass screw given how easily destroyed the plastic screws are, but stuck some lube on the thread to attempt to avoid corrosion. I wonder what metal the pipe is? Aluminum?

 

I'm assuming its some aluminum alloy. If you ever had a garden hose with aluminum ends and you try to connect it to a brass hose bib you will quickly understand the meaning of never being able to take it apart again.

If you have a plastic part the brass screw would be the ideal option. They might also sell those screws in stainless which would be more compatible then aluminum and brass.

 

I'm thinking about this as a replacement for the brass screw to avoid any kind of corrosion.

 

That is a solid option. It looks anodized.

 

Update - bought the anodized screw above and replaced my brass screw with it today. Voting for this as the best option.

Holding the base of the head against the top of the threaded hole confirms it's not too long to interfere with the flow of coolant

Thanks for the update, going to order mine.

 

Thank you so much for the cross reference on the Ford P/N! I was going crazy trying to find the correct part. I def owe you a beer!

 

Thank you for the important info,

Is this the same bleeder screw that is used on the coolant reservoir tank?

 

The exact factory radiator drain plug is available from Dorman?




This is a picture of my factory Jaguar radiator drain plug and the correct Dorman #61138 replacement. Available nearly anywhere too.
Around $6-$8. I usually tear up the slots in the head getting it out. I use a dab of silicone grease on the rubber seal when re-installing to help prevent sticking in the future.

Sorry, i'm looking for the expansion tank bleed screw in the engine bay.

 

Correct but the thread is titled Radiator drain screws?
