Hello! I have problem and trying to fix it about 6 months. And no one can help me. I want to know if it possible to speak with man who knows jaguar v8 engines well. The problem is that coolant water goes out when i stop engine. until it can work all day ewerything will be ok. The temperature is normal (in video computer shows 95 celcius). But when turn off engine after 5seconds water goes out and when i take off collant bottle cork the bottle is empty. I have maked video please watch it and maybe you can tell to me what it can be from your experience?

Fuzzy picture when I look for alignment of the plastic overflow tubes coming out of the reservoir; but it looks like they are swapped, which will cause the coolant blow at shutdown.

 

Is the thermostat housing a plastic one? Little hard to tell in video.

 

I agree with Jim. On the coolant container, where you top up the coolant, pointing towards the front of the car are 2 pipes, one goes to the Radiator and one goes to the Overflow container. Looking from the drivers seat, the one from the Radiator is connected to the left hand connection, and the one from the Overflow container should go to the right-hand connector. These 2 pipes should cross.
Cheers
Bill W,

 

One more thing. I was trying to drive that car when i reached 80km/h speed i stopped car (engine was runing) and the water was coming out from the same place when engine is off. When engine works but not drives water doesnt come out. but when turn off it or drive a little bit water comes out. And one more thing i was trying to open that hole witch one is on the top of water pump (can see in video). and there was no water just hot air. I hawe changed 2 times gaskets first time was not original gasket but the result was the same second time have bought original jaguar gaskets and anyway the same thing water goes out. I have checked if block is not broken and block head. block and block heads ar good not broken. have checked thermostat when hot water comes it opens hole. I dont know what els i can do... that car is killing me slowly Oh and maybe someone know something about vanos? (https://www.youtube.com/watch?v=QBzwp9YnAyA)this is not jaguar vanos but jaguar have 2x vanoses. now my engine is shaking and noysy as hell when driving all time i hear strange sound something is knocking more speed faster knocks. i dont know maybe i have changed something vith vanos..

 

yes it is plastic.

 

By vanos I think you mean VVT, camshaft advance. But I don't think that is causing rough running and knocking sound.

You may have blown a head gasket at some point, or skipped a tooth or even two on a exhaust cam.

I would suggest you remove the valve covers and check camshaft alignment before running the engine again.
Also, pay attention to what Jim and Bill said about lines being crossed.

 

post a large clear picture of the hoses at the header tank near the windscreen.

the hose attachment has been pointed at twice as a common source of this
problem. this is the third.

 

If you have confirmed the overflow tubes are correctly installed and you are still blowing coolant and running rough then I would suspect a blown head gasket. You may need to do a compreesion check.

 

Here is a diagram showing the connections at the reservoir. Note that they are crossed.

Problem SOLVED!!! I dont know how to say that big Thankyou guys. The collant bottle connectors was in wrong holes. i have crossed them and problem solved water doesnt goes out anymore 6 months we was thinking that the problem is bigger gasket clock crash... omg.. i have spend 1000$ for checking heads for new gaskets and so on. Now i will know if something will be wrong with my jaguar i will take camera and make video for you guys Once more big thx! I love this forum!

 

as always, a picture is worth a thousand words. Even more so when we don't share the same primary language.

 

Problem not solved! Please watch other video in new post! Big thx to all! https://www.jaguarforums.com/forum/x...3/#post1122329
