Coolant loss at backof engine in the intake area?
So I was driving todayand got a low coolant warning. Decided to get to a gas station down that was within a quarter mile and add coolant, when suddenly the dash lit up and warned of overheating. Luckily I was able to pull over right away, and fount coolant leaking outof the back of the motor near the intake. Any ideas? See the picture attached.
Had the car towed to JLR in Torrance, but it will take them 2 days to get to it.
Are threre fittings under there?
Any help would be appreciated.
Thanks

Leaking from that area is probably from a crack in the coolant pipe which runs under the back of the supercharger, a well known problem on older V8 (AJ133) SC engines, and the V6 (AJ126) SC has the same coolant pipe.
Unfortunately it's a SC off job to replace so lots of labour cost but you should still be covered by the warranty.
Also, what's with the green fluid I can see in a couple of spots, especially sitting in the bottom of the 2 cm x 2 cm x 20 cm square tube under the Symposer pipe?
On most cars fluid of that colour would be coolant but all modern Jags take the "pink" coolant and I can see pink fluid stains at the back of the SC.
Or is the green appearance just a trick of the light and the photo?

just went through this last week here's my thread:
https://www.jaguarforums.com/forum/f...-204195/page2/
haven't posted resolution notes just yet but it was the pipe under the supercharger -- took a full day of labor [out of warranty]. My water pump was also bad so we replaced that too. Wasn't a particularly cheap repair but not too bad either. I think it was under $2k total.

Coolant
I was wondering the same thing. It was definitely green coolant but what was left in the reservoir was pink. The car has been in for one service to the dealer so really not sure why there are two colors? I will bring that up with them. I have never added coolant myself.

Thanks for the advice-why is it important to get a compression test, I literally pulled over within 50 feet of the warning? Also, the car only has 8200 miles. Is this normal for a low mileage car??
I have asked the dealer to see if they do this as well. Thanks

Not normal, but my last one had a leak at 83 miles (yes, 2 digits) that turned out to be a radiator defect - dealer was asked by factory to ship radiator back ASAP as it was “very rare”. For me it was just a few days with a loaner, so not a big deal.

I would still be worried about the green coolant, it is not a good idea to mix green and pink (AKA red or orange) coolant.
Although it is odds on the dealership will drain, flush and refill the coolant as part and parcel of the warranty fix I would bring it to their attention anyway and insist on them doing this. I would also ask them if they could explain how green coolant got into the system!

Coolant color
Yes, absolutely. I sent them an email this morning asking how this could have happened, printed it out and put it in my file.
Thanks!

"These days, there’s no real reason for a coolant manufacturer to use a certain colour, so it’s not easy to know what chemicals are in the coolant just by seeing whether it’s blue, green, yellow or orange."

I'm not so sure about that. Coolant is colored for a reason - I think good sense would trust but verify. Green is traditionally GO5 coolant, red OAT. There are varying products that claim one is compatible with mixing vs the other. I used to be a coolant systems engineer and I would beg to differ based on real life reliability.

There seem to be at least three categories of coolant IAT, OAT and HOAT.
I believe that all coolant is clear until the manufacturer adds a dye.
There doesn't seem to be any universal standard for these colours.
The G-05 you refer to is I believe HOAT yet I understand Chrysler version was orange and Ford version was yellow.
I stand by my original assertion that coolant colour cannot reliably identify coolant composition.

I also believe this to be the case because my car has only been serviced at the dealer and never had the coolant system touched until two weeks ago when I had the issues -- mine also appeared green when outside the system in the sun.

Several things in this thread incorrect.
1 that heater pipe on the back of the engine does not require the sc to come off. It is not under the supercharge but bolted to the back of the block. The v8 held on with 4 bolts and the v6 with 6. Regardless theyre a pain in the **** to charge.
2 the orange or red depending how you r color pallet is the long life coolant jaguar has used for years. And in certain light conditions it does "appear" green. Its still the correct coolant regardless. And i love this coolant so much because it stains leaving deposits that dont go away when dry i use it in not only my jaguar, but nissan, and both chevys. And because i get it at work

Agree with Brutal post.
FORD WSS-M97-B44-D is I believe
equivalent to the recommended
JAGUAR LAND ROVER STJLR.651.5003
see my earlier thread
F type coolant

What I should have said was it is possible to replace that heater hose without removing the SC but a real pig of a job, and very much easier to do with the SC off and out of the way.
Many owners on the XF forum recommend that if/when the SC is taken off (to renew the coupler, repair, replace, whatever) that is a good time to also replace that rear coolant pipe before it starts leaking.
