Major coolant leak!
Well it looks like the big one has finally happened!! It was fairly cold this morning (~15ºF) and now I have a major coolant leak that has resulted in an empty coolant reservoir. There are specs of coolant all over the top and rear of the engine.
I am pretty pissed about this, because there was no warning light on the dash in the entire 30 minute drive! Who would design a car without a temp gauge that also has no warning about low coolant! |
Damn. This is why I added the CAMP2. I hated not having a coolant temp gauge. Got any pics? Sounds like it could be a heater hose.
|
I will try to get a pic, but I am about to have the car towed.
|
Had the same issue a while ago. Lower nipple on the plastic coolant reservoir tank was cracked. Replacement tank, new fluid and pressure check cost around $225. at the indie that I use.
Good luck. Best, |
I, too, am taking it to an indie shop. I wouldn't be surprised if it was the coolant reservoir being cracked, seems like a common thing on these cars.

I wonder if you guys can see these photos, but here goes:

The shop says the leak is coming out from underneath the supercharger, so they will need to remove it. Based on their experience with other JLR engines, there is some sort of hose assembly that can develop a pinhole leak and would need to be replaced. Total bill will be north of $1500!!!
|
Damn - sorry to hear it. Keep us posted.
|
Good news! The total, I'm told is closer to $1100. Should be done by the weekend--parts will take a while to get. He says there's two hoses accessible under there that would be a good idea to replace now (well, one is busted!).

There should be a check in the coolant tank that puts on an amber warning light if the coolant drops below it.

Is there even a coolant level sensor?
COOLING SYSTEM for 2007 Jaguar XKR I don't see anything that looks like a sensor in this parts list! |

My 2009 kicked a light on when the coolant tank was low.
|
I can't see one either - I think the only coolant sensor is for temperature. Presumably low coolant results in a change to that sensor's readings.
|
Interestingly, the '09 model parts list looks the same. So maybe it's measuring coolant somewhere other than on the coolant reservoir tank??

OMG...I think you are right. I see no reference in the owners manual to a fault message and no sensor in the electrical diagrams. That is really unbelievable. Other Jags from this time period had one.
|
jagtoes, looks like you could be right, but it also sounds like the system just infers that the system is low on coolant if it gets abnormal readings from that water temp sensor. So perhaps by the time you get a "low coolant" warning, you're already overheating?
