Default Coolant Flush

Hi there,

I want to flush the coolant on my 95' XJR but I'm having trouble finding the petcock/radiator drain plug. I have read other threads that it is on the passenger side of the radiator but I still can't find it. I will attach a photo of what I saw under there.

Thanks in advance!

If you can't find it I would just undo the bottom hose. Then fill the system up with distilled water, run it for a bit, drain again, and repeat. Finally fill with the proper fresh coolant.

The drain plug is black plastic and has either one slot as shown below or possibly two slots in an X pattern. I can't remember if it's closer to the left or right end. The "arrow" end of the plug helps prevent it from falling into your catch pan if you loosen the plug all the way.


I can't tell about that first photo, but the object in your second photo looks like a radiator mounting stud. There are two molded into the bottom of the radiator that sit in foam bushings to hold the radiator in place and protect it somewhat from vibration. Your bushings are deteriorated and it would be a good idea to replace them, along with the smaller ones that isolate the air conditioning condenser, which can develop a leak if the bushings aren't replaced and the soft aluminum condenser rubs against a hard steel brace.

As AJ16er suggested, it's about as easy to just disconnect the lower radiator hose, though it's a bit messier. Whether it's more likely that the head of the drain plug will snap off or the ridge around the lower hose plastic fitting will break off is anyone's guess, so whichever method you choose, be very careful with these old plastic parts.

Cheers,

Don

G’day Shinda,

That looks like the drain plug in your first pic. Undo it and you should see a captive plug as in the other post.

Cheers,
Jeff.

Not meaning to hijack the original poster's thread, but what brand of coolant is generally preferred in a moderate temperature region?
(Only occasionally gets at all below freezing here.)
thx

Hi montoya66,

Jaguar's coolant recommendations vary by year, model and engine. The short answer is that brand is generally irrelevant, it's the chemistry that matters. Let us know the year, model and engine of your Jag and I'll move your post to start a new thread.

Cheers,

Don

G-05 or regular green would be my guess. Maybe somebody knows for sure.
