1990 Jaguar XJ6 2.9 Manual from UK and Ireland

Summary:

The best £800 I have ever spent on a car..

Faults:

Nothing really, central locking on one of the rear doors failed, but I fixed it. Seal on the petrol filler neck had perished and made the boot damp, I replaced it myself. The part cost £4 from a dealer!

I looked at lots of old Jags before choosing this one. My advise is buy the best you can for as little as possible. There are some genuine bargains out there.

General Comments:

Its only a 2.9 and so needs full throttle to get it to move!

But once the old girl gets going it will outrun the average hatchback.

Full leather interior, wood, climate control, chrome and full electrics. I have never experienced a car so luxurious for the money. It can do 28 MPG on the motorway which is not that bad for such a big car.

I own a 1989 2.9 Jaguar and it does have a problem with detonations which are mentioned in the Jaguar Handbook and only related to the 2.9. When the detonations occur the smoke emitted from the exhausts is of such density that everything behind is totally obscured. Imagine the embarrassment. This model does not like short journeys nor does it like the winter season. It seems that in cold weather the choke causes heavy deposits of carbon which,when the engine heats up and is then placed under load, produces detonations which are caused by the carbon burning off. I have not figured out how it also burns so much oil when these detonations occur.

For carbon build up and to keep ones economy try Dipetane. This product stabilizes the carbon chain and reduces the co2 emissions.

Would love one of these stunning looking cars.

1990 Jaguar XJ6 Sovereign 4.0L from North America

Summary:

What a joke!

Faults:

Everything!!! I had to replace just about all electronic parts and sensors. The heating control, rear end, on board computer, mufflers, sunroof motor, rear defrost, radio, and many other parts.

Don't buy this car, what a lemon. As you can see it only has 40,000 miles on it, should I have so much trouble? Very unhappy with this product, Jaguar is nothing but a name!

Same experience on this side of the Atlantic. Bulb failure modules, spurious warning lights, rear axle noise, harsh automatic gearshifts, excessive and uneven tyre wear, suspension bushes, oil leaks, intermittent power steering when cold, rear shock absorbers leaking (repeatedly), wind noise and waterleaks from the doors. The list was endless. One too many 6-page service bills from the dealer and I got off the merry-go-round. Phew!!

1990 Jaguar XJ6 Vanden Plas 4.0l 6 cyl from North America

Faults:

I replaced the water pump at 115,000 miles. The onboard diagnostics are a bit touchy - they will indicate that a tail light bulb is out when in fact it's working, for instance.

The A/C compressor failed at 125,000 miles.

General Comments:

Very reliable car, especially considering its undeserved reputation for unreliabilty. I've owned two others - one an '89, the other a '90. Both were delightful cars.

These cars depreciate in value rapidly, which makes them incredible value on the used car market.

I need your help! I just purchased a 1990 Jaguar XJ6 4 door sedan. I just love this car. However, I took it to have an oil change, but the mechanic stripped the threads on the oil pan. I had to call the automobile club to tow my car home. What can I do at this stage. Are there any solutions to this unfortunate problem? PLEASE advise me. Awaiting your reply.

Easy fix!

The CHEAP route is to purchase Jaguar's repair kit.

You can get it from a dealer, if they'll put out the effort for a car that old (NOT likely), or buy one from Jaguarclassicparts.com while they last.

You could also buy a used oil pan from a junkyard.

Whichever path you choose to take, you should have the repair garage pay for the repairs, suing if necessary. It's their fault the threads were stripped!

1990 Jaguar XJ6 4.0L from North America

Faults:

I had to replace the water pump, the exhaust system (only because the previous owner had a cheap one put in.) And some occasional quirks... The antenna won't go down all the way sometimes. The power seat adjustment fails on occasion. The right rear power door lock doesn't work every time.

General Comments:

Quite powerful. Not very expensive to run in US with cheap fuel costs. Very luxurious and now affordable. Why pay more for a newer economy car?

Yes! Basically a good motor.

Getting on for 200,000 miles in mine.

Had to have new a head gasket set and replaced the timing chain whilst about it.

New real wheel bearings at the back.

Only irritating problem has been abnormal tyre (tire) wear on the front inside edges. Can't seem to fix this. Mainly on the offside.

Any comments may result in me going for the 300,000 mile mark.

I recently purchased a 1990 xj6 Soverin.I purchased the car for a mere seven hundred dollars. There are only a couple things wrong the car had been broken into they stole the head rests they had the TVs. And of course the speakers and CD player and the caps from the wheels, but other than that its beauttiful...

Sounds like you've had faulty wheel balancing.
