Ah, that makes perfect sense. By the way, I found out the coolant capacities on the X-Type here! http://jaguar.telko.ru/Vehicle%20Spe...%20models).pdf It's the official vehicle specifications document from Jaguar for the 1998 to 2003 model years.

On page 45, it lists the coolant spec for both the X-Type 2.5 and 3.0 as WSS M97B44–D, and the coolant system capacity as 10 litres (10.6 US quarts). It's actually super helpful to know this, since it'll allow me to measure how much coolant drains out of the system and calculate how much residual fluid is left in there when I go through the drain and refill process.

 

So how does this story end? How much was left after draining? Did the green and orange get along? Don't leave us hanging!!!

 

:-) So I did my first drain and re-fill a couple of weeks ago - I raised the front of the car on ramps so I could get easy access to the drain plug and...only 4 quarts of fluid came out! WTH?

Anyway, I mixed in exactly 4Q of new fluid with the 4 to 6Q of old fluid that was apparently still left in the cooling system. The reservoir level's been holding steady since then, and the car's driving beautifully so far. I figure I'll keep the current coolant mix in the car for another couple of weeks, and will then drain and refill the fluid a few more times to get nearly all the old fluid worked out.

I'm not sure if a full 8 quarts would have drained out if the car had been level or if the rear end was lifted. The next time, I'm going to try to raise the rear end to see if more of the old coolant drains out.

PS. Definitely don't ever mix green and pink coolant. My 2005 has pink coolant, so I replaced it with a similarly pink coolant meeting the Jaguar spec.

 

Thx mattsteele, I'm gonna try ur method. My 06 cts caddy also has 5 yr or 150k mi replacement. Need done now

 

Thx Matt that was very helpful. Gonna do my 06 caddy next

 

I used universal coolant and mixed it at a 60/40 ratio. Then also add some Steel Seal or Blue Devil to keep the head gaskets happy. Works well so far.

 

How much of the Jaguar brand will I need for a full flush? Also a rouge mechanic topped it off with the green stuff, should I do any extra flushing or use a pre flush aid?

 

Green and Orange mixed, usually turns to a gel mess.
Amounts are in the post on the top of this current page.

Just FYI, Pentosin is the OEM for the Jag coolant.

 

The "new" X-type I just got has been services at the dealer since new, and still had the factory fluid in it, 67K miles in. For sh*ts and giggles, I send some off to the lab (along with my other fluids) to see what kind of condition it was in, and what exactly it was.

What came back was a 50/50 mix of Pentosin Pentofrost SF and distilled water, just a little tired (13 years old, you think that had something to do with it?), but still has its lubricants and anti-galling chemicals intact. There are only traces of aluminum in it, consistent with the mileage. There are NO silicates in it at all. I guess when they call this stuff long-life, they mean it!

Probably not a bad idea to replace it, or at least refresh it. Found it locally, a bit pricey though, about $14 for a liter-and-a-half of concentrate...but that's half the price that Jag wants for it!

By the way, my brake fluid is also factory, and it is TRASHED. The recommend a complete flush of the whole system. It is full of moisture, and goes a long way to explaining why the calipers were all just replaced. I plan on putting Goodridge braided lines on anyway, So I'll have the system totally cleaned out and refilled.

By the way, forget adding water-wetter to the coolant; it's in there right from the factory, it's be coals to Newcastle to add it.
