coolant loss Jaguar S type 2005
hello
Frequent loss of coolant, Jaguar S type 2005
A Jaguar dealer told me it was a blown up Head Gasket.
i decided to use a head gasket repair sealant. but after a week or so the coolant started going low again. Through all these times, i
have always been able to use the car even for longer distances eg. Netherlands - Poland (about 14 hours drive) and back, without any issue
of overheating for almost 2 years, I don't see any white smoke from the exhaust, no milky substances of the coolant.
Recently i have constantly seen leakages of coolant around the engine and i keep adding coolant to keep the level.
I feel it's not actually the head gasket because the coolant is not been consumed by the engine.
with new cap for the overflow tank, still the same.
Now, i can't use the car for longer distances because anytime i go beyond 120-140 km/h, the coolant overflows through the cap
leading the engine to overheat, and the car to "Restricted Performance".
Any advice?

The radiator and heater core should be drained and backflushed to remove any residue left from the sealer. The cooling tubes of modern radiators are actually quite small and can become easily blocked by products claiming to 'seal' leaks.
Follow the procedure in the Workshop Manual, which you can download here:

I think I have found where the leak is coming from. Now it has really become really serious because I can actually see it dripping off under the water pump. I also see some water inside the water pomp area but the leaking is actually coming from under. Now I fill up the tank and within minutes is gone.(1 does it mean there is problem with the water pump? I am thinking of taking it to the specialist. Wanted to see if there's any idea from the community
