  1. After more investigation, I have found the culprit... the radiator! The problem got much worse quite quickly but I was having trouble tracking where the leak was from, but eventually I managed to replicate the problem just running the Jag on the driveway. Once the engine gets up to temperature, there is a jet of coolant shooting out of the top back of the radiator just next to the header tank. The jet is spraying straight across the engine bay and hitting a spinning pulley opposite, which is then spraying the coolant everywhere, which is no doubt why I've been having such a hard time locating the fault. Looks like I'll need a new radiator! DOH!
  2. Thanks for the reply Russ! I suspect you are correct. I've had a poke around with the inspection lamp and I can't see anything obvious... apart from coolant staining around the side of the header tank. I've had search around and I have seen a new tank for around £60 so I'll fit one of those and see if it makes a difference.
  3. Hi everyone! I have a 2002 Jaguar S Type with the 3.0 V6 petrol engine, which I acquired recently. The car drives brilliantly, really smooth and no overheating etc. However, I am losing coolant somewhere quite rapidly (it will go from max to min in the header tank within about 30 miles). I can't immediately see any puddles etc under the front of the car so I'm at a bit of a loss. I can't see any signs of oil in the coolant or coolant in the oil, but the coolant is obviously going somewhere. I've had a good poke around the forum and I have noted down what seem to be the most common causes (header tank, bottom of radiator, water pump etc). But as I say, I can't immediately see anything. I have a tool that pressurises coolant systems (I used it some years ago on another motor) to check for leaks, but whenever I've used it before I put it straight onto the top of a radiator. Can I used something like that tool straight onto the header tank? I can't think of any reason why I wouldn't be able to, given that the tank is designed to be pressurised anyway, but I want to make sure I'm not making things worse! Thanks for the awesome forum!
  4. Hi everyone, I am new to the forum and new to owning a Jag. I have acquired a 2002 Jaguar S Type with the 3.0 V6 petrol engine. I like to tinker with my cars and do most repairs myself, so this forum is no doubt going to become my new (virtual) home. Most immediately, the Jag is losing coolant somewhere so I'm off to search the forum for the most likely causes. Thankfully there is no sign of oil in the coolant / coolant in the oil and I understand that the head gaskets on the V6 engines tend not to blow so I'm hoping I haven't bought a pup! Thanks for the bountiful information contained within the forum!
