Hello All,

Well, the Ford replacement EVAP canister we put on my 2001 S-Type last year has given up, and turned on the check engine light. Apparently there is not a replacement part available from Jaguar (that's what the service people tell me), and when I tried to get one from JagBits, it wouldn't fit my car despite the numbers saying it would. Does anyone have any suggestions? I'd prefer not to take the risk with the engine - if something else fails I might not know it til she dies on the road. Any recommendations would be welcome!
Thank you in advance!
Mary

 

Hi Mary,

What exactly is wrong with the existing canister? Has the plastic shell cracked? Or has one of the external valves failed? I'd hate to see you chasing after some hard-to-find part, only to discover that's not really the problem.

What code do you have? P0445? That's a common one for a leak in the EVAP system. Details here, page 30. Note the laundry list of possible causes in the far right column:

When I searched the forum, I came across your thread from about a year ago on the same subject. Are you seeing the same symptoms as before?:

In theory, the EVAP canister should last the life of the car. It's basically just a fancy charcoal sponge inside a plastic shell. The external valves (sold separately?) may wear out from use, but the canister itself should last forever. Unfortunately, several forum members have reported cracking in the plastic shell, but that seems to be the only problem with the canister itself.

A quick search of RockAuto showed two possible replacements, large and small. Does either one look correct?:

I've never heard of WVE brand, so no idea of the quality. However, if you click the info button for either part, you will see a whole slew of interchange part numbers. The number starting with XR is Jaguar, but I believe that's just a Ford part in a very expensive Jaguar box. The long numbers starting with F are Ford numbers. The other numbers are private brands such as AutoZone, etc. So if you don't want to gamble on WVE brand, you could search for one of those other numbers and see what you find.

What about the Ford part currently installed? Do you still have the part number for that? Has the shell cracked? If not, the problem probably is an external valve, not the canister.

And if the problem is a cracked shell, I'd be willing to gamble your hard-earned money on an epoxy repair.

 

Hi Karl,

The car was serviced at the local Jaguar dealership and the only information I was given is that the reason the check engine light came on was the EVAP system. I have a vague idea where this sits in the car, but certainly don't know enough about it to determine if it's a cracked case or failed valve. It's pretty clear the dealership is not going to help find a replacement part, since the service advisor told me she was aware of other vehicles that have the check engine light on for years and they keep running. I'm sure they'd prefer I traded my car in for a new Jaguar.

The Ford replacement they installed last year was found by the service manager - I showed the tech the picture of the part I saw on JagBits based on the part numbers I was given, and they said it would work. I bought the part, took it and my car to the shop, and then the tech said it wouldn't work. I didn't know they had to call JagBits and talk about why the part wouldn't work, so I was unable to return the part.

If there was another service option in the northern Illinois - southern Wisconsin area, I'd love to know about it.

 

It can be frustrating to work with a dealership service department. They are typically limited to official Jaguar parts and procedures. One good example is worn ball joints. The official repair is to replace the complete suspension arm ($$$), even though only the ball joint is bad. But quality replacement ball joints are available in the aftermarket, at a much more reasonable price. In most cases, an independent repair shop is the way to go. These cars aren't so exotic that only a dealer can touch them.

The best of both worlds is to find an independent Jaguar specialist, so they'd have experience with some of the quirks. Sorry I can't recommend one in your area. I know of two such shops in the Portland area, unless the rioters have already been there to strike a blow against the bourgeois class.

 

You might want to make a post in the "US Midwest" regional forum asking for a reference for a good "indy" shop familiar with Jaguars in your area:

One more thought:

Not 100% sure, but I bet the Jaguar EVAP system is very similar to other cars of the same era in the Ford family. Any shop that could figure this out on a Taurus could probably figure it out on an S-Type, too.

 

The Lincoln LS is a similar car. Parts will sometimes interchange.

 

Some gee-whiz details of the EVAP system here, pages 42-43:

Page 43 shows the arrangement of the charcoal canisters. There's a small single canister, and a large double canister, for a total of three. A valve and pressure sensor are located with the canisters. Another valve is located under the hood.

Also see page 38, showing the location of the canisters, aft of the fuel tank and above the rear axle.

 

It is. They performed a limited diagnostic because the purge valve was stuck open. Will see if I can find an independent service place close to home.
Your advice has been much appreciated!
