I gave a 2008 XKR Portfolio Convertible and I want to drain only the coolant. From previous owners service record it was done 35k ago when the thermostat housing was replaced.
I would like to know how many L / Qt I need to do just a drain and fill. I’ve done some searches but was unable to find that info.
Can only one provide that info and what fluid did you use other than dealer stuff?

 

Capacity on the SC model is 11.5 litres. Required concentration is 50% so you will need 6 litres of coolant for a drain and refill which leaves a little over for later topping up.





OAT coolant to specification WSSM97B44-D is available in many brands. It always used to be orange which made identification straightforward but some manufacturers have gone to pink and other colours.

I just get mine from the dealer. Given the money I spend on fuel to drive the thing for five years (the coolant change interval), the additional cost doesn't get me too excited.

Graham
Thank you for the info.

 

But, describe DRAIN... The total capacity is 11.5 liters, but how much of that can be 'drained' out without fully draining the block and other passages? I've used compressed air to get as much as possible, but there will always be some more somewhere without popping off some freeze plugs.

 

Graham, Coolant threads can be a bit of a nightmare, since the original Ford spec takes some searching to find. Quiet day, so I did some searching:

The Motorcraft Orange is supposedly obsolete here in the states. Yes, it still is spec'd on the Motorcraft website at https://www.motorcraft.com/us/en_us/...-coolants.html. But a call to the parts grunts at Ford stops dead at "make and model?", since if it's not Ford they default to "can't help you". But the website says the spec you mention above.

Until very recently, Peak has (had) an Orange coolant that the data sheet claimed met the Ford spec. It also says it meets ASTM D3306 and D4985. I used it to meet the Ford spec. But it's not on their website anymore. Probably still in parts stores that sell Peak.


Next was finding a common spec that's equivalent to the Ford one. This seems to be ASTM D3306. For instance, the Havoline image below says ASTM D3306 and the Ford specs are the same:




So, I think the spec to search for is the ASTM D3306.

Here's the back of the Dexcool bottle, which has both the ASTM D3306 spec and the original Ford spec (which seems to be fading away on the bottle spec lists).

Right below that is Zerex "American Vehicle" which is ASTM D3306, but doesn't have the Ford - Jaguar spec. Looks like just a branding difference.

I guess the Zerex Dexcool is the winner replacement, as long as the spec is ASTM D3306, since it's easily available.

I hope this helps. I'll go to Dexcool next time around if it still exits as branded, or "American vehicle" Dexcool.

 

Any OAT LongLife antifreeze will be fine. Usually orange/pink but try and choose the same colour as you have at the moment because you can't get it all out unless you do several plain water flushes and if you mix colours you end up with brown. If you don't buy ready mixed antifreeze then it's best to use distilled/deionised water for flushes and concentrate dilution.

 

Oleguy,

I have the same car as you, just in Coupe form and performed this service as part of a water pump replacement.
I'd offer a few more bits to what the other posters have mentioned:
First, if you don't already have it, you can download a copy of the Owner's Manual which will have all the capacities listed. Second, I would also suggest downloading a copy of the Service Manual for your specific VIN as it will have the Drain, Refill and Bleed procedure spelled out. Both manuals are available for download on this Forum.
For coolant, I found Zerex G30 covering all spec's necessary (calls out specifically JLR also) at my local O'Reilly Auto Parts. I've not had any issues with it in the year it has been in the car (knock on wood). It is already pre-mixed to 50/50.

By just draining the radiator, you won't be able get all of the coolant out as other posters have mentioned as a lot of it will stay in the block, heater core, supercharger, supercharger coolers and associated hoses.You could always try raising the rear end a bit and hopefully gravity will give you a helping hand.

Kind Regards,
Ken
