I thought my 03 Jaguar s 3.0 was safe from Coolant leak problem, but it was not!! ,

About 2 weeks ago, The Engine coolant low sign was shown and right away I put enough amount of Coolant in it. Also, I opened the bonnet to check either if leaking was visible and real or just problem of sensor. At that time, I could not find any certain spot where the leak was started and even since it happend last winter frequentlyshowing the warning sign), so I just came up with it was just happend for no reason or problem of sensor whatever.

But few days ago, the warning was shown again, and I finally could see serious leak from the reservoir. The coolant was seemed like either flowing from the reservoir or just dripping from it(especially, around the hose connected to the reservoir).
I put more coolant to get rid of the warning to maximum level after that, but even today the warning was shown again when I got back from drving for a while, as the coolant was leaking too. Even it was much more amout than the other day when I checked it before. It was literally dripping and flowing coolant from the reservoir!

But I am not sure so I put a pic of it.
Plz tell me what do u guys think, so that I would decide to replace the reservoir or find some way to fix this sad problem.

Thank you!

 

Very common. Search will get you details of what to do.

 

Get a new reservoir.

 

you can get a new resovoir, or do what I did to my XJ....I filed away the fins on the plastic lead(whatever was left of it), got a regular screw type camp...I clamped the hose as tight (not too tight at all) to the remainder of it, then I sealed it with gray rtv gasket sealant, been fine since last fall.

 

Sealing by some stuff wouldn be perfect step, but it would be ok for a while temporarily.
Hm.. It seemed like finding new reservoir is not that easy compared to other jag part. The thing is I only could find one website selling the reservoir...
Anyway, Thx guys for replying me

 

Dealers sell them and they're "only" mildly expensive.

 

The clamp holds the hose onto the stock needle (thats assuming your needle broke like mine), and the sealant is just added insurance. Mine didnt leak without it, just an added measure. I did it nice and clean and see no need to replace mmine.

OP, as jagv8 said, dealers have them. you should call one, or pm ken@britishcarparts or nally jaguar. They are active members and sponsors.

 

Nalley gives the best prices, 15% off for us forum members, and free shipping for anything over $25. He sent me a radiator hose that was 2x the price on the lowest search I could find online. He and Ken are my go-to's.
