Coolant Job 2003 4.2

Coolant Job 2003 4.2
So... I've had my 2003 S Type for a few years and haven't had any major issues at all. Just passed 100,000 miles. I was getting the coolant low warning, but whenever I checked the level was topped off, so I figured it was the sensor. I was just about to put a new tank in when I got a massive leak, like a trail of coolant behind the car! Towed to the garage and got told that the bottle is the only thing NOT leaking, they said the water pump is leaking and "all of the plastic coolant passages" (couldn't be more specific, said I wouldn't understand) need to be replaced. My price $2100. help, please.

Maybe I'm being too vague, I basically would love any insight as to what could be the issue and what the consensus is as to the resolution (parts, average cost of repair...) I unfortunately am having a very hard time finding a mechanic in my area as it seems that once they see the leaper their eyes turn to dollar signs.

There are many threads describing cooling system repairs to the 4.2 engine. Search the forum using "4.2 engine cooling system repairs" as your search phrase and you will have at least a couple of hours of reading to do. Most of us 4.2 owners (my wife has a 2006 XK8) have done these repairs ourselves using the advice and guidance provided here on the forum. For the sake of your checkbook, I hope you can as well....

You've reached the mileage at which the radiator is prone to let go, but that is usually a small drip that would explain your recurrent coolant low-level caution. I'm not sure this failure even has the capability to progress to spewing a trail of coolant and smoke, perhaps but probably noticeable as a puddle long before that.
I'm unfamiliar with the 4.2L but assume it has some version of the plastic upper rad hose fitted to the 3.0L in which case it is likely leaking. Unsure if you have the plastic or metal water pump impeller, but recall they are an issue on the V-8's. T-stats also prone to stick closed, which may have highlighted and exacerbated whatever weak point was causing your coolant low-level light.
As Jon noted, nothing in the coolant loop you couldn't handle...even if you are a tool-less city-dweller.....you could buy a lot of tools for $2100.....and yeah, you may make a few mistakes along the way...but think how much you'll learn!

Thank you, I am searching the forum now. I am all for DIY aside from the fact that this is my wife's daily driver so time is not on my side. Again, I thank you all for your insight!
(on a side note, no smoke - just low coolant and temp gauge creeped up to overheat. Wife promptly pulled over and cut the engine, and it went directly to the shop)

Until you open the hood and tell us what's actually leaking, not much point guessing.

To replace all the rubber hoses with Jaguar parts is around $200. You can get a Jaguar water pump and thermostat pipe assembly for another $150. If you need a radiator, new will cost you $250. Purchase the hoses at Las Vegas Jag online. Pump and pipe at Terry's Jag.

Do NOT buy a Jaguar water pump!
I have posted this before but ALL 4.0L, 4.2L and Lincoln LS 3.9L V-8's as well as Land Rover 4.2L and 4.4L V-8's use the same water pump. Get the Lincoln LS one and look for the improved aftermarket one. The box will say improved over stock on it. They have improved the impeller and seals.
It's easy to get and has a lifetime warranty from Oreilly. I got one at 9PM on a Sunday night. CP4124 about $90.

You may have come across the above thread in you search. If not, have a read.
I would also change out the Hose AJ 811763, and purchase the remote hose clamp ring tool. Makes life so much easier.
Check the hose part number for your car.

Again I have been thru this before. Jaguar is very late to the party on this and should have released an upgraded version years earlier. I use the aftermarket Chinese one.
Where is the factory one made? Does it come with a lifetime warranty? No of course not.
I only replace radiators when I have to. Just too expensive and too much work. I don't consider them a wear item.

No...it fails in a benign manner.....drip, drip, drip at a lesser frequency than Clinton e-mail scandals. You'll have ample time to obtain a replacement and make the change on a weekend, as long as you keep a sharp eye on the level. Just beware on the 03 and sub facelift (3.0L) cars, the airflow drives it onto the DCCV and makes it appear as if that's where the leak is. I don't know the DCCV arrangement on the 4.2L's so can't speak to that.

Sorry wrong again!
I come from the Lincoln LS side where this failure came much earlier than S Type because Ford sold a lot more LS's especially in 2000. That's why I don't even tell them it's for an S Type. Shop for the LS pump instead.
Get the one you want it's your car!
Still did not answer what the warranty is on the Jaguar branded pump??
It's NOT lifetime. Again make your own choice.
I did.
