04 Jaguar X-Type - Coolant Leak

Vehicle: 2004 Jaguar X-Type 3.0
Mileage: ~95,000 miles
Problem: Coolant Leak


Recently, a problem has developed where it seemed to get a bit hot and upon turning it off, the fan continues to operate for some time- seemingly to cool down the engine. Realizing that it appeared to have been low on coolant, I added coolant and it was fine for a couple days before I had to add a bit more.

Now, it has gotten to the point where I have to add coolant virtually every time I drive in order to keep it from getting hot. Obviously, it seems there is a coolant leak of some sort, but I do not know much more than that.

Any thoughts or ideas of what might be causing this or how it can be fixed? I sincerely appreciate any help/guidance regarding this problem. Thanks, everyone!

if u have to keep adding coolant, its going somewhere. either its leaking outside the engine or inside it.

if u look around and dont see signs of a leak, u can borrow a pressure tester at autozone or another parts store with a free tool loaner program. pump up the cooling system to the psi for your radiator cap and go over the underhood area real close. under pressure even a small leak will show up.

if u cant find a leak this way, it could be leaking on the inside, which most often means a blown head gasket or cracked head    do u see white smoke coming out the exhaust? thats one sign of this.

to confirm it u can buy a block test kit at a parts store. this will detect any combustion gas in the coolant, if its there, your looking at a bad head gasket or head. possibly a cracked block.

let us know what u find out.

Thank you very much for your help!

I did the pressure test as you mentioned and the problem was discovered.

It seems that the coolant reservoir tank connection to the hose was broken, which because it was pressurized, was causing the coolant to constantly escape. Basically, the nub that extends from the reservoir tank and connects to the hose was broken and barely hanging on, which required the entire tank to be replaced.

Sadly, this is only available from Jaguar which resulted in being forced to purchase the tank from the dealership at a $300+ cost. Since the repair, all has been well and there have been no issues since. Thanks for your help!
